Real Parties in Interest.
INTRODUCTION AND OVERVIEW
Real parties in interest Derrick Hunter and Lee Sullivan (defendants) were
indicted by a grand jury and await trial on murder, weapons, and gang-related charges
arising out of a drive-by shooting in San Francisco. Each defendant served a subpoena
duces tecum on one or more petitioners, social media service providers Facebook, Inc.
(Facebook), Instagram, LLC (Instagram), and Twitter, Inc. (Twitter) (collectively, social
media providers, or simply providers). The subpoenas broadly seek public and private
communications, including any deleted posts or messages, from the social media
accounts of the homicide victim and a prosecution witness.



As explained below, the federal Stored Communications Act (18 U.S.C. § 2701 et
seq., hereafter SCA or Act)1 regulates the conduct of covered service providers, declaring
that as a general matter they may not disclose stored electronic communications except
under specified circumstances (including with the consent of the social media user who
posted the communication) or as compelled by law enforcement entities employing
procedures such as search warrants or prosecutorial subpoenas. Providers moved to
quash defendants’ subpoenas, asserting the Act bars providers from disclosing the
communications sought by defendants. They focused on section 2702(a) of the Act,
which states that specified providers “shall not knowingly divulge to any person or entity
the contents of” any “communication” that is stored or maintained by that provider. They
asserted that section 2702 prohibits disclosure by social media providers of any
communication, whether it was configured to be public (that is, with regard to the
communications before us, one as to which the social media user placed no restriction
regarding who might access it) or private or restricted (that is, configured to be accessible
to only authorized recipients). Moreover, they maintained, none of various exceptions to
the prohibition on disclosure listed in section 2702(b) applies here. And in any event,
providers argued, they would face substantial technical difficulties and burdens if forced
to attempt to retrieve deleted communications and should not be required to do so.
Defendants implicitly accepted providers’ reading of the Act and their conclusion
that it bars providers from complying with the subpoenas. Nevertheless, defendants
asserted that they need all of the requested communications (including any that may have
been deleted) in order to properly prepare for trial and defend against the pending murder
charges. They argued that the SCA violates their constitutional rights under the Fifth and
Sixth Amendments to the United States Constitution to the extent it precludes compliance
with the pretrial subpoenas in this case.

Future undesignated statutory references are to title 18 of the United States Code.

The trial court, implicitly accepting the parties’ understanding of the SCA, agreed
with defendants’ constitutional contentions, denied providers’ motions to quash, and
ordered them to produce the requested communications for the court’s review in camera.
Providers sought, and the Court of Appeal issued, a stay of the production order. After
briefing and argument, the appellate court disagreed with the trial court’s constitutional
conclusion and issued a writ of mandate, directing the trial court to quash the subpoenas.
We granted review.
Our initial examination of the Act, its history, and cases construing it, raised
doubts that section 2702 of the Act draws no distinction between public and restricted
communications, and that no statutory exception to the prohibition on disclosure could
plausibly apply here. In particular, we questioned whether the exception set out in
section 2702(b)(3), under which a provider may divulge a communication with the
“lawful consent” of the originator, might reasonably be interpreted to permit a provider
to disclose posted communications that had been configured by the user to be public.
Accordingly, we solicited supplemental briefing concerning the proper
interpretation of section 2702. In that briefing, all parties now concede that
communications configured by the social media user to be public fall within section
2702(b)(3)’s lawful consent exception to section 2702’s prohibition, and, as a result, may
be disclosed by a provider. As we will explain, this concession is well taken in light of
the relevant statutory language and legislative history.
The parties differ, however, concerning the scope of the statutory lawful consent
exception as applied in this setting. Defendants emphasize that even those social media
communications configured by the user to be restricted to certain recipients can easily be
shared widely by those recipients and become public. Accordingly, they argue that when
any restricted communication is sent to a “large group” of friends or followers the
communication should be deemed to be public and hence disclosable by the provider
under the Act’s lawful consent exception. On this point we reject defendants’ broad view
3

and instead agree with providers that restricted communications sent to numerous
recipients cannot be deemed to be public — and do not fall within the lawful consent
exception. Yet we disagree with providers’ assertion that the Act affords them
“discretion” to defy an otherwise proper criminal subpoena seeking public
communications.
In light of these determinations we conclude that the Court of Appeal was correct
to the extent it found the subpoenas unenforceable under the Act with respect to
communications addressed to specific persons, and other communications that were and
have remained configured by the registered user to be restricted. But we conclude the
court’s determination was erroneous to the extent it held section 2702 also bars disclosure
by providers of communications that were configured by the registered user to be public,
and that remained so configured at the time the subpoenas were issued. As we construe
section 2702(b)(3)’s lawful consent exception, a provider must disclose any such
communication pursuant to a subpoena that is authorized under state law.
Ultimately, whether any given communication sought by the subpoenas in this
case falls within the lawful consent exception of section 2702(b)(3), and must be
disclosed by a provider pursuant to a subpoena, cannot be resolved on this record.
Because the parties have not until recently focused on the need to consider the
configuration of communications or accounts, along with related issues concerning the
reconfiguration or deletion history of the communications at issue, the record before us is
incomplete in these respects. Accordingly, resolution of whether any communication
sought by the defense subpoenas falls within the statute’s lawful consent exception must
await development of an adequate record on remand.
We will direct the Court of Appeal to remand the matter to the trial court to permit
the parties to appropriately further develop the record so that the trial court may reassess
the propriety of the subpoenas under the Act in light of this court’s legal conclusions.

I. FACTS AND LOWER COURT PROCEEDINGS
A. Grand Jury Proceedings and Indictment2
According to testimony before the grand jury, at midday on June 24, 2013, Jaquan
Rice, Jr., was killed and his girlfriend, B.K., a minor, was seriously injured in a drive-by
shooting at a bus stop in the Bayview district of San Francisco. Various surveillance
videos showed a vehicle and someone firing a handgun from the rear window on the
driver’s side. A second person was depicted leaving the vehicle from the rear passenger-
side door and firing a gun with a large attached magazine.
Witnesses identified defendant Derrick Hunter’s 14-year-old brother, Quincy, as
one of the shooters. During questioning in the early morning hours after the events,
police homicide detectives told Quincy that they had “pulled all Instagram . . . [and]
Facebook stuff,” and were aware that he knew the shooting victim. Quincy related that
the victim had “tagged” him on Instagram in a video featuring guns. The detectives
responded that they had been “working all day” on the matter and had “seen those posts.”
Quincy admitted that he shot the victim six times — and asserted that the victim “would
have done the same thing to us.”3
Quincy stated that “Nina,” his girlfriend’s sister, had provided the car in which he,
his brother, and one other male had driven. Within a few minutes of the shooting, police
2
This and the following sections are based on the grand jury transcripts, of which
we have taken judicial notice, as well as material in providers’ appendix of exhibits —
including pretrial moving papers and the transcripts of two sessions of a pretrial hearing.
3
Ultimately Quincy was tried in juvenile court, found to be responsible for Rice’s
murder and the attempted murder of B.K., declared a ward of the court, and committed
to the Department of Juvenile Justice for a term of 83 years four months to life. Under
Welfare and Institutions Code section 607, subdivision (b), however, because of his age
at the time of the crimes, he will not be confined beyond his 25th birthday. After the
Court of Appeal affirmed in an unpublished opinion (A142771), we granted review
(S238077) and held that matter pending disposition of the present litigation.

had stopped Nina, whose real name is Renesha Lee (hereafter sometimes Renesha), while
driving the vehicle shown in the videos.
Renesha was codefendant Lee Sullivan’s then girlfriend. She had rented the car
used in the shooting and gave varying accounts of the events. According to her testimony
before the grand jury, during the course of multiple interviews on the day and night of the
killings, she initially “just made up names and stuff.” Eventually she told the police that
defendant Derrick Hunter and his younger brother Quincy were among those who had
borrowed her car. Renesha did not mention defendant Sullivan’s name until a few days
later, when she “told them the truth about [Sullivan],” and that he had been involved
along with the Hunter brothers.
Renesha related that on the day of the shooting she had driven with Sullivan and
the Hunter brothers to a parking lot where they “got out and walked to Quincy[’s] house.”
She explained that Sullivan told her the three young men were going to a store. Renesha
recalled that she replied she would remain at the house and talk to her sister. She testified
that Sullivan had not been wearing gloves when he and the others initially approached her
to borrow the car, but she noticed that he was wearing gloves when they came out of
Quincy’s house and when they departed. According to Renesha, Sullivan drove away
with the Hunter brothers in the backseat. She testified that when the three returned the
car to her shortly thereafter it contained the phones of Sullivan and Derrick Hunter. She
also testified that she had never seen Sullivan or either of the Hunter brothers with a gun.
Renesha explained that she had initially not revealed Sullivan’s involvement
because she had been scared and “just didn’t want to have no parts of it because I’m the
one that still has to live and walk these streets.” She elaborated that once the police
informed her that she might be arrested for murder, she “told them the truth,” and yet still
avoided implicating Sullivan until later in the process because she remained fearful of
him. She maintained that after being threatened with prosecution she eventually told the
full truth about Sullivan’s role.
6

In presenting the case to the grand jury, the prosecution contended that defendants
and Quincy were members of Big Block, a criminal street gang, and that Rice was killed
for two reasons: (1) Rice was a member of West Mob, a rival gang, and (2) Rice had
publicly threatened defendant Derrick Hunter’s younger brother Quincy on social media.
Inspector Leonard Broberg, a gang expert and member of the San Francisco Police
Department Gang Task Force, testified that in his opinion the alleged crimes were
committed for the benefit of the Big Block gang. He explained that “gangsters are now
in the 21st century, and they’ve taken on a new aspect of being gangbangers, and they do
something they call cyber banging. [¶] They will actually be gangsters on the internet.
They will issue challenges; they will show signs of disrespect, whether it’s via images or
whether it’s via the written word. . . . [¶] [They use] Facebook, . . . Instagram,
Socialcam, Vine . . . [and] YouTube. . . . They will disrespect each other in cyberspace.”
Inspector Broberg described a YouTube video made by victim Rice and shared by him
via his Facebook account, in which he gave a tour of his West Point/ Middle Point
neighborhood and identified specific places where he could be located — including the
bus stop where he was shot. Broberg characterized the video as a challenge to others.
In a subsequent declaration, Broberg explained that he “rel[ies] heavily on records from
social media providers such as Facebook, Instagram, and Twitter to investigate and
prosecute alleged gang members for gang crimes,” and that in the present case, he “relied
in part on” such records to secure evidence that Rice, Sullivan, and the Hunter brothers
“were members of rival gangs and that the shootings were gang related.” The same
declaration adds: “We [the police] have not sought search warrants as to Renesha Lee.”4
4
Toward the end of the proceedings, the prosecutor read to the grand jury some
“exculpatory evidence . . . that was requested by the defense attorneys in this case be
presented to you.” The panel was told that two witnesses reported to police that a young
woman had been driving the car, and that one witness had identified the driver as
Renesha Lee. Yet another witness identified the driver as Quincy Hunter.
7

Defendants were indicted and are presently charged with the murder of Rice and
the attempted murder of B.K. They also face various gang and firearm enhancements.
(Pen. Code, §§ 187, 664, 186.22, subd. (b)(1), 12022, subd. (a), 12022.53, subds. (d) &
(e)(1).
B. Description of the Subpoenas
Prior to trial, in late 2014, both defendants served subpoenas duces tecum (Pen.
Code, § 1326, subd. (b)) on Twitter. Defendant Sullivan’s subpoena sought “[a]ny and
all public and private content” that had been “published by” Renesha Lee, who was
identified by an attached photocopied screen shot of one of her Twitter accounts. The
request specified no temporal boundary and stated that it “includes but is not limited to”
(1) so-called record data, consisting of “user information [and] associated e-mail
addresses,” “activity logs,” and “location data”; and (2) content information, such as
“photographs, videos, private messages, . . . posts, status updates, . . . , and comments
including information deleted by the account holder.” It further sought the identity and
contact information concerning the custodian of records who could authenticate the
requested materials. Defendant Hunter’s subpoena, issued a few weeks later, sought all
“accounts” and tweets originating from Renesha Lee’s “account and in response to or
linking her account” from the beginning of 2013 “to the present.” Neither defendant
sought from Twitter any communication concerning victim Rice.
Only defendant Sullivan served subpoenas on Facebook and Instagram. The
Facebook subpoena requested information regarding the accounts of both Rice and
Renesha Lee. The language of the subpoena tracked Sullivan’s request to Twitter,
broadly seeking “[a]ny and all public and private content,” including deleted material,
that had been “published by” either Rice or Renesha Lee, each of whom was identified by
an attached photocopied screen shot of that person’s Facebook account. As with
Sullivan’s subpoena served on Twitter, the subpoena specified no temporal boundary and
sought the same record data, content, and authentication information mentioned above.
8

Sullivan’s subpoena served on Instagram similarly sought “[a]ny and all public
and private content,” including deleted material, published by Rice and Renesha Lee,
each of whom was again identified by photocopied screen shots showing their account
information.5 In all relevant respects the demands for record, content, and authentication
information tracked the demands directed to the other social media providers.
C. Providers’ Responses to the Subpoenas
Counsel for Facebook and its subsidiary Instagram responded to the Sullivan
subpoenas by a single letter in December 2014, asserting that as providers governed by
federal statute (the SCA), they are precluded under that law from divulging the requested
stored communications. The letter stated that under the SCA only the government may
compel covered providers to divulge such stored content. Accordingly, the letter
recommended that defense counsel instead seek the requested information directly from
the account holder or from “any party to the communication” — persons who, unlike a
covered provider, are “not bound by the SCA.” Alternatively, the letter suggested that
defense counsel might “work[] with the prosecutor to obtain” the requested information
via an additional search warrant issued by the government.6 A few days later, different
5
It appears from the record that there may have been up to four relevant Instagram
accounts, at least one for Renesha Lee and possibly three for Rice. A photocopied
screenshot attached as an exhibit to the subpoena pertaining to Renesha Lee indicated the
account had four posts, one follower, and eight accounts that the account holder was
following. It also shows an image of a padlock, with a notation, “this user is private.”
According to subsequent pretrial briefing by defendants, “Mr. Rice had multiple social
media accounts” and “many . . . have been deleted, including accounts gang expert
Leonard Broberg relied upon at the grand jury hearing.” Moreover, according to that
same subsequent briefing, defendants also asserted that “many of [Renesha Lee’s social
media] accounts have been deleted.”
6
Finally, the letter explained that if defense counsel were to withdraw each
subpoena “to the extent it seeks content,” Facebook and Instagram might produce “non-
content information” regarding the specified accounts, “such as basic subscriber
information and [internet protocol] logs” — information that defense counsel might use
to contact other parties to the communications, in order to attempt to obtain the
9

counsel in the same law firm responded similarly on behalf of Twitter to defendant
Sullivan.
Eventually all three providers moved to quash the subpoenas. They reiterated the
assertions in their letters that defendants might try to obtain the requested information
directly from the social media user who posted the communication, or from any recipient7
— or perhaps via an additional search warrant issued by the prosecution.8 They also
information directly from them. (“Basic subscriber information” (more fully described
post, fn. 23) and internet protocol logs are forms of record/non-content data that, as
implied in the letter, might be employed to identify a recipient of a communication in
order to attempt to obtain electronic communications directly from that person.
7
In this regard, providers relied on decisions such as O’Grady v. Superior Court
(2006) 139 Cal.App.4th 1423, 1447 (O’Grady) [even when the Act precludes disclosure
by a provider, it “does not render the data wholly unavailable; it only means that the
discovery must be directed to the owner of the data, not the [SCA-regulated service
provider] bailee” who is barred from disclosure]. (See generally Fairfield & Luna,
Digital Innocence (2014) 99 Cornell L.Rev. 981, 1058 [suggesting that a “defendant
could locate the relevant originator or recipient by accessing non-content identifying
information, such as an IP address, and then seek production [from that person]
directly”].
8
Of course defendants are independently entitled to general criminal discovery,
including exculpatory evidence, from the prosecution under Penal Code section 1054.1.
Moreover, under authority such as Brady v. Maryland (1963) 373 U.S. 83, People v.
Salazar (2005) 35 Cal.4th 1031, 1042-1043 (and cases cited), and Barnett v. Superior
Court
(2010) 50 Cal.4th 890, 900-901, the prosecution is obligated to share with the
defense any material exculpatory evidence in its possession — including that which is
potentially exculpatory. (See also Rules of Prof. Conduct, Rule 5-110(D), amended Nov. 2,
2017 [requiring “timely disclosure to the defense of all evidence or information known to
the prosecutor that the prosecutor knows or reasonably should know tends to negate the
guilt of the accused, mitigate the offense, or mitigate the sentence”] and corresponding
discussion [observing that “the disclosure obligations in paragraph (D) are not limited to
evidence or information that is material as defined by Brady v. Maryland . . . and its
progeny. For example, these obligations include, at a minimum, the duty to disclose
impeachment evidence or information that a prosecutor knows or reasonably should
know casts significant doubt on the accuracy or admissibility of witness testimony on
which the prosecution intends to rely.”].) As explained below, consistent with its
discovery obligations under state and federal law, the prosecution has apparently shared
10

objected that the requests as drafted were overbroad and vague. In any event, providers
asserted, disclosure directly from them, as entities covered by the SCA, was barred by
that federal law. In that respect providers’ motions relied upon section 2702(a), which
broadly states that a covered “person or entity” such as providers “shall not knowingly
divulge to any person or entity the contents of a communication while in electronic
storage by that service.” (Italics added.) Based on this language, providers asserted that
the SCA’s prohibition on a provider entity’s ability to disclose any content information
applies broadly and does not depend on whether the registered user configured a given
communication as private/restricted as opposed to public. Moreover, providers asserted,
none of section 2702(b)’s exceptions to the bar on disclosure by a provider applies here.
Nor, they observed, does the Act contemplate procedures for criminal defendants to
compel production of such communications.
D. Defendants’ Opposition to the Motions to Quash
Defendants opposed the motions to quash,9 but they did not contest providers’
assertion that section 2702(a) prohibits providers from disclosing any of the sought
communications — even those configured by the registered user to be public. Nor did
defendants challenge providers’ assertion that none of section 2702(b)’s exceptions apply
in this case. Instead, defendants argued that their federal constitutional rights under the
Fifth and Sixth Amendments to a fair trial, to present a complete defense, and to cross-
examine witnesses support their subpoenas and render the SCA unconstitutional to the
with defendants information relating to victim Rice’s social media accounts. (See post,
fn. 10.)
9
As the Court of Appeal observed below: “[T]he record before us [makes it unclear
whether defendant] Hunter joined in the opposition to the motions to quash below, but he
has formally joined in Sullivan’s arguments in this court. For simplicity’s sake, we refer
to the opposition below as that of [d]efendants collectively.” We adopt the same
approach.
11

extent it purports to afford providers a basis to refuse to comply with their subpoenas.
Defendants acknowledged that no court had ever so held, and asked the trial court to be
the first in the nation to do so.
Defendants presented offers of proof concerning the information sought from the
various accounts. The prosecution had secured from Facebook and Instagram some of
the available social media communications attributed to Rice and, as obligated, had
shared that information with defendants in the course of discovery.10 Regarding the
information concerning Rice’s communications, defendants asserted that review of the
full range of content from those various accounts is required in order to “locate
exculpatory evidence” and to confront and cross-examine Inspector Broberg, in order to
challenge his assertion that the shooting was gang related. In support defendants cited
Broberg’s grand jury testimony and attached examples of five Facebook screen shots
reflecting videos alleged to have been posted by Rice. Counsel asserted that the
subpoenaed records would show that Rice was “a violent criminal who routinely posted
rap videos and other posts threatening Quincy Hunter and other individuals.”
Although the prosecution had secured and shared some of Rice’s Facebook
communications and a portion of the Instagram posts attributed to him, the prosecution
had not sought from providers the social media communications of their key witness,
Renesha Lee. Nevertheless, it appears from the record that at least one of Renesha Lee’s
Twitter accounts was public and contained numerous tweets that were accessible to
defense counsel. Counsel evidently accessed that account and identified content that,
10
(See ante, fn. 8.) Defendants subsequently asserted, however, that although they
have had “access to some of Mr. Rice’s social media records through the discovery
process that tend to support the prosecution’s theory of the case,” still they lacked “access
to records necessary to present a complete defense and to ensure the right to effective
assistance of counsel.” Thereafter, in their joint reply brief filed in this court, defendants
characterized the prosecution as having declined to obtain all of Rice’s various Instagram
accounts.
12

they asserted, indicated a strong likelihood that other similar, yet undiscovered — and
possibly deleted — communications might exist. Defendants alleged that the
prosecution’s case turns on Renesha Lee’s credibility and that “she is the only witness
who implicates Sullivan in the killing.”11 Moreover, defendants explained, they sought
additional corroborating information, consistent with that found already in Renesha Lee’s
public tweets, to demonstrate that she was motivated by jealous rage over Sullivan’s
involvement with other women and that she had repeatedly threatened others with
violence.
In support of these assertions defendants’ opposition appended, as an exhibit,
photocopied screen shots of what was represented as two of Renesha Lee’s Twitter
accounts. They quoted a September 2013 tweet showing a photograph of a hand holding
a gun and making specific threats: “I got da. 30 wit dat extend clip….. BIIIITCH I
WILL COME 2YA FRONT DOOR…..” Various other tweets from both accounts
suggested a similar theme. Defendants asserted their need for and intention to use these
and any other similar tweets, posts, comments, or messages, including deleted content,
made by Renesha Lee on Twitter, Facebook, or Instagram, in order to impeach her
anticipated testimony at trial. Defense counsel stated that, despite diligent efforts,
Renesha Lee could not be located to be served with a subpoena duces tecum.
E. The Hearing on the Motions to Quash
The first session of the bifurcated hearing on the motions to quash was held in
early January 2015. The trial court began by explaining that, in light of the pleadings, it
was inclined to find the sought material “critical” to the defense against the pending
charges, and to conclude that “defendants have a [constitutional] right to . . . information
11
Quincy, in his earlier confession, acknowledged that his brother Derrick was with
him in the car when the shooting occurred, but he did not mention Sullivan as being in
the car with them. Instead, he asserted that a third person, named Johnson, had been with
him and his older brother in the car.
13

that’s authentic . . . [and] reliable.” The court questioned providers’ alternative proposal
that the prosecution could or should issue additional search warrants to them (the service
providers) on behalf of defendants: “First, I think the District Attorney’s office is going
to . . . say[], . . . our job is not to perform your investigation for you. And, besides, the
Penal Code . . . authorizes search warrants to be obtained [only] under certain
circumstances, and . . . not to find evidence that might support an affirmative defense or
mitigate a mental state [or impeach a witness].” The court also expressed concern about
defendants’ ability to obtain any tweets or posts that may have been deleted by the
account holder, and regarding how those communications might be authenticated
sufficiently to be allowed into evidence. In that respect, the court questioned whether
Renesha Lee would be willing to “take ownership” of tweets attributed to her and quoted
above, “[s]ome [of which] could be subjecting her to criminal liability.”
The trial court next addressed Twitter’s assertion that any “deleted contents”
would “not [be] reasonably available” and hence providers would “not . . . be able to
produce deleted contents or authenticate deleted content.” The court expressed
skepticism concerning Twitter’s assertion that it would be unable to produce deleted
content, observing: “[W]hat I . . . know from my time in discovery [is] that when I delete
e-mails, they are not all deleted. [¶] Now, I don’t know . . . to what extent they are kept
on some server or archive that could be retrieved through some sort of search function, or
whether some forensic computer person has a way of reconstructing files or not. [¶] So
. . . if you are going to say that you complied and . . . state under penalty of perjury
[supported by a] showing . . . that you have done what you can do, that’s a separate thing.
But, I doubt very much I am going to change my position that this material is critical, it
has to be produced, and you are the ones holding it.” Accordingly, the court tentatively
denied the motions to quash and ordered that the materials be provided to it for in camera
review pursuant to Penal Code section 1326. At the same time, the trial court allowed
additional briefing to be filed before it ruled finally on the matter.
14

In its subsequent brief Twitter reiterated its assertion that section 2702 of the SCA
fails to “distinguish between ‘private’ and ‘public’ content for purposes of its restrictions
on providers’ disclosure” and it maintained that “service providers are prohibited from
producing any content, regardless of status.” Facebook and Instagram asserted in their
own subsequent brief that section 2702 of the SCA bars the requested discovery and that
the Act “contains no exception for criminal defense subpoenas.” Consistent with their
broad assertion that no exception applied under section 2702, they did not address
whether any of the sought communications had been configured by the account holder to
be public or private/restricted. Twitter, by contrast, directly confronted that issue in its
own final supplemental responsive brief, noting that one of the accounts in question is
public, and that “[a]s of this filing, anyone can visit the account and review its content,
including messages, photos, and videos. In fact, defendant has already done this and
included some public content from the account in . . . support of his Opposition [brief].”12
In response, defendants contested the assertions by Facebook and Instagram that
defendants could gain access to the sought communications by other means.13 They
12
Twitter also stated: “On Twitter, if an account is public, its Tweets are public — a
user cannot make individual Tweets public or private on a post-by-post basis.” Further,
Twitter addressed the trial court’s stated concerns regarding retrieval of deleted content.
It asserted that even if the SCA permitted it to comply with the subpoenas’ demands, still,
any “content deleted by the user is not reasonably available to Twitter.”
13
Regarding Rice, defendants noted that because Facebook allows the default to be
changed — and posts to be configured as public or private on a post-by-post basis — not
all friends might have “content that Mr. Rice decided to withhold from a particular user.”
As observed ante, footnote 10, defendants conceded that they had access to some of
Rice’s social media records through the discovery process. But, they insisted, they
nevertheless lacked access necessary to present a complete defense. Regarding Renesha
Lee’s social media records, defendants did not contest Twitter’s assertions that one of her
Twitter accounts was public and remained open and accessible to all as of the time of the
trial court briefing and hearings. Still, defendants asserted, “many of [her other]
accounts” (apparently referring especially to the Facebook and Instagram accounts
mentioned earlier) “have been deleted,” and hence they had no access to them, and yet
providers did possess those “inactive and active accounts.”
15

argued that unless providers are ordered to comply with the subpoenas, they will be
deprived of the information they need and also will be hampered in their effort to
“persuade a jury that the records in question originated from Ms. Lee’s social media
accounts.”
After considering the additional briefing, in late January 2015 the trial court
confirmed its earlier conclusions, commenting that it would be “untenable” to deny the
requested material to defendants. The court further explored with the parties the issues of
deleted communications and burdens that compliance would impose on providers. In that
regard counsel for providers asserted that deleted tweets “don’t persist in backup for all
eternity” and to the extent some remained in storage, “they are going to be very
cumbersome and burdensome to obtain.” The court responded that it had insufficient
information with which to weigh the benefit of production versus burdens, and noted that
it could easily impose a temporal restriction on the information sought in order to render
the request more reasonable and less burdensome. The court then asked counsel to
address recovery of deleted content concerning “your other clients” — Facebook and
Instagram. But that discussion never occurred, producing an evidentiary lacuna as to
those providers. Thereafter, neither the parties nor the court addressed whether any of the
sought tweets had been configured as public, or whether, for any time period, the user
had protected the account and made tweets sent during that time accessible to followers
only. Nor did the court or parties address the privacy configurations of the remaining
Facebook and Instagram communications sought by defendants.
F. The Trial Court’s Ruling on the Motions to Quash
The trial court finalized its tentative rulings, denying all three motions to quash
and ordering that providers submit all of the sought materials for its in camera review by
a deadline in late February 2015.14 The court stated that it understood providers might
14
As the Court of Appeal observed, defendant Hunter apparently did not formally
oppose Twitter’s motion to quash his subpoena. Nevertheless, the trial court assumed
16

seek writ review challenging its oral production order, and recognized that the Court of
Appeal might stay its production order.
After discussing the need for a preservation order (see post, fn. 47), the court
vacated the trial date, which had been set for the next day. All parties agreed to
reconvene in early March, after the trial court had an opportunity to conduct in camera
review of the information that the providers had been ordered to produce, or alternatively
at a later date pending resolution of the writ proceeding providers intended to file
contesting the court’s oral production order.
G. The Writ of Mandate Proceeding
Providers jointly filed a petition for a writ of mandate in the Court of Appeal
contending that the trial court abused its discretion in denying the motions to quash.
They asked the appellate court to “preserve the status quo” by issuing an immediate stay
of the trial court’s production order and planned in camera review. That court stayed the
trial court’s production order and issued an order to show cause asking why the relief
sought in the petition should not be granted.
After full briefing and oral argument, the Court of Appeal filed an opinion
concluding that the SCA barred enforcement of defendants’ pretrial subpoenas and
rejecting defendants’ arguments that the Act violated their rights under the Fifth and
Sixth Amendments to the federal Constitution. Reviewing the relevant case law with
respect to the constitutional claims, the appellate court concluded: “The consistent and
clear teaching of both United States Supreme Court and California Supreme Court
jurisprudence is that a criminal defendant’s right to pretrial discovery is limited, and
lacks any solid constitutional foundation.” (Italics in original.) The appellate court
stressed, however, that its conclusion was confined to “this stage of the proceedings” and
such a motion and denied it on the same basis that it denied the motions to quash
defendant Sullivan’s subpoenas.
17

limited to the “pretrial context in which the trial court’s order was made.” (Italics in
original.) It observed that defendants would remain free to seek “at trial the production
of the materials sought here.” The appellate court commented that the trial judge who
would eventually conduct the trial “would be far better equipped” than the appellate court
itself “to balance [defendants’] need for effective cross-examination and the policies the
SCA is intended to serve,” and suggested that the SCA might eventually need to be
declared unconstitutional to the extent it precludes enforcement of such a trial subpoena
issued by the trial court itself, or by defendants, with production to the court. With
respect to the pretrial context, however, the appellate court directed the trial court to
vacate its order denying providers’ motions to quash the pretrial subpoenas, and to grant
the motions to quash.
II. PROPER INTERPRETATION OF THE
STORED COMMUNICATIONS ACT
Because the parties agreed in the trial court that the SCA precluded providers from
complying with defendants’ subpoenas and the court accepted that proposition, the trial
court proceeded on the assumption that providers’ refusal to comply with the subpoenas
raised only constitutional questions. It then decided the matter by resolving those
constitutional issues in defendants’ favor. As explained above, the Court of Appeal
likewise viewed the case as raising only constitutional issues, and its decision in
providers’ favor was grounded on the appellate court’s conclusion that defendants’
constitutional claims were not viable in the pretrial context.
In their initial briefing in this court, the parties again proceeded on the assumption
that the litigation raised only constitutional issues, and they debated the merits of
defendants’ constitutional contentions. Defendants reiterated the view that their federal
constitutional right to due process under the Fifth Amendment, and their confrontation,
compulsory process, and effective assistance of counsel rights under the Sixth
Amendment, require that the Act be declared unconstitutional to the extent it precludes
18

the enforcement of their subpoenas in this case. They candidly recognized that case
authority supporting their position is sparse. Ultimately, they suggested that we should
overrule or distinguish our own decisions (especially People v. Hammon (1997
15 Cal.4th 1117 and its progeny) in order to declare the SCA unconstitutional as applied
and uphold their pretrial subpoenas. Providers, by contrast, asserted that no decision of
any court supplies authority supporting defendants’ entitlement to pretrial enforcement of
their subpoenas. They argued that, to the extent defendants might later at trial be able to
establish a due process right to the information they seek in order to secure a fair trial,
their remedy at trial would not lie in a judicial declaration that the SCA is
unconstitutional as applied to them. Instead, providers asserted, the trial court should at
that time put the prosecution to a choice: (1) use its authority under the Act to acquire the
sought materials on behalf of defendants and share them with defendants at trial, or
(2) suffer consequences in the form of an adverse evidentiary ruling at trial, including
potentially pivotal instructions to the jury, or outright dismissal of the prosecution’s case.
As mentioned, our initial review of the SCA and the relevant legislative history of
the pertinent provisions, as well as prior judicial decisions addressing related issues, led
us to question the validity of the statutory interpretation of the SCA on which the case
was litigated below. Specifically, we questioned whether the relevant statute, section
2702(a), which appears to bar providers from disclosing electronic communications
configured by the user to be private or restricted, also bars providers from disclosing
communications that had been configured by the user to be public. Accordingly, we
requested supplemental briefing directed to that issue, identifying the portions of the
legislative history that appeared most relevant.
As explicated post, part III.A., in the ensuing supplemental briefing all parties
concede that section 2702(b)(3)’s lawful consent exception permits providers to disclose
public communications. In order to understand the relevant provisions of the SCA and
why we also conclude that the statute should be so construed, it is appropriate to review
19

the Act’s general history, the language of the relevant statutory provisions, the specific
legislative history of those provisions, and prior relevant case law.
A. The SCA — History and General Background
Congress enacted the Electronic Communications Privacy Act in 1986. (ECPA;
Pub.L. No. 99-508, 100 Stat. 1860.) Title I of that law, amending the prior “Wiretap
Act,” addresses the interception of wire, oral, and electronic communications. (§§ 2510-
2521.) Title II of the law, set out in chapter 121, is often referred to as the Stored
Communications Act, or SCA. It addresses unauthorized access to, and voluntary and
compelled disclosure of, such communications and related information. (§§ 2701-2712.
Prior to the ECPA’s enactment, the respective judiciary committees of the House
of Representatives and the Senate prepared detailed reports concerning the legislation.
Each explained that the main goal of the ECPA in general, and of the SCA in particular,
was to update then existing law in light of dramatic technological changes so as to create
a “fair balance between the privacy expectations of citizens and the legitimate needs of
law enforcement.” (H.R. Rep. No. 99-647, 2d Sess., p. 19 (hereafter House Report); see
also Sen. Rep. No. 99-541, 2d Sess., p. 3 (hereafter Senate Report) [speaking of
protecting both “privacy interests in personal proprietary information” and “the
Government’s legitimate law enforcement needs”].)15 Each report also highlighted a
related objective: to avoid discouraging the use and development of new technologies.16
15
The House Report described privacy protection as “most important,” and noted:
“[I]f Congress does not act to protect the privacy of our citizens, we may see the gradual
erosion of a precious right. Privacy cannot be left to depend solely on physical
protection, or it will gradually erode as technology advances.” (House Report, supra, at
p. 19, fns. omitted.) The Senate Committee expounded on this theme, observing that
“computers are used extensively today for the storage and processing of information,”
and yet because electronic files are “subject to control by a third party computer operator,
the information may be subject to no constitutional privacy protection” absent new
legislation. (Sen. Rep., supra, at p. 3; accord, House Rep., supra, at pp. 16-19.
16
In this latter regard, the House Report, noting the “legal uncertainty” that
surrounded the government’s legitimate access to such stored information, expressed
20

These three themes — (1) protecting the privacy expectations of citizens, (2) recognizing
the legitimate needs of law enforcement, and (3) encouraging the use and development of
new technologies (with privacy protection being the primary focus) — were also
repeatedly emphasized by the bill authors in their debate remarks.17 As this history
reveals, and as a leading commentator on the SCA has explained, Congress was
concerned that “the significant privacy protections that apply to homes in the physical
world may not apply to ‘virtual homes’ in cyberspace,” and hence “tried to fill this
possible gap with the SCA.” (Kerr, A User’s Guide to the Stored Communications Act,
and a Legislator’s Guide to Amending It (2004) 72 Geo. Wash. L.J. 1208, 1210.)18
concern that such conditions may expose law enforcement officers to liability, endanger
the admissibility of evidence, encourage some to improperly access communications, and
at the same time, “unnecessarily discourage potential customers [from] using such
systems.” (House Rep., supra, at p. 19.) Similarly, the Senate Report cited the same
potential problems, and added that legal uncertainty might not only discourage use of
“innovative communications systems” but also “may discourage American businesses
from developing new innovative forms of telecommunications and computer
technology.” (Sen. Rep., supra, at p. 5.
17
For example, Congressman Kastenmeier, the bill’s primary author, stressed as a
governing principle “that what is being protected is the sanctity and privacy of the
communication.” (132 Cong. Rec. 14879 (1986), at p. 14886.) Senator Leahy, the bill’s
sponsor in the upper house, repeatedly referred to the need to “update our law to provide
a reasonable level of Federal privacy protection to these new forms of communications”
in order to address inappropriate acquisition by “overzealous law enforcement agencies,
industrial spies, and just plain snoops” of “personal or proprietary communications of
others.” (132 Cong. Rec. 14599 (1986), at p. 14600.) Cosponsor Senator Mathias
described the legislation as “a bill that should enhance privacy protection, promote the
development and proliferation of the new communications technologies, and respond to
legitimate needs of law enforcement.” (Id., at p. 14608.
18
Congress’s conception of the internet more than 30 years ago was, of course,
substantially different from the internet that exists today. “The World Wide Web had not
been developed, and cloud computing services and online social networks would not
exist for nearly a decade. Internet users in 1986 could essentially do three things:
(1) download and send e-mail; (2) post messages to online bulletin boards; and (3) upload
and store information that they could access on other computers. The definitions and
prohibitions listed in the SCA align with these three functions as they existed in 1986.
21

B. Key Provisions of the SCA
1. Rules regarding unauthorized access to stored communications: Sections
2701 and 2511(2)(g)(i)
Section 2701(a) provides that, subject to specified exceptions, “whoever . . .
intentionally accesses without authorization a facility through which an electronic
communication service is provided” or “intentionally exceeds an authorization to access
that facility” and “thereby obtains” an “electronic communication while it is in electronic
storage in such system” commits an offense punishable by a fine or imprisonment. At the
same time, a separate provision contained in another part of the ECPA, section
2511(2)(g)(i), articulates a substantial limitation on section 2701’s access prohibition:
“It shall not be unlawful under . . . chapter 121 [that is, the SCA] . . . [¶] . . . to . . .
access an electronic communication made through an electronic communication system
that is configured so that such electronic communication is readily accessible to the
general public.”19
2. Rules prohibiting disclosure by service providers and listing exceptions
under which providers are permitted to disclose “communications” or
“customer records”: Section 2702

Section 2702 addresses disclosure by certain covered service providers — and by
no other person or entity. (Wesley College v. Pitts (D.Del. 1997) 974 F.Supp. 375, 389.
Subsection (a)(1) declares that, subject to specified exceptions, “a person or entity
providing an electronic communication service[20] to the public shall not knowingly
Because Congress has not updated the statute, courts have struggled to apply the SCA in
light of the explosive growth of the World Wide Web.” (Ward, Discovering Facebook:
Social Network Subpoenas and the Stored Communications Act
(2011) 24 Harv.J.L. &
Tech. 563, 566, fns. omitted (Discovering Facebook).
19
Section 2707 authorizes a civil action to enforce these and the following
provisions of the SCA.
20
An electronic communication service (ECS) is defined as “any service which
provides to users thereof the ability to send or receive wire or electronic
communications.” (§ 2510(15).
22

divulge to any person or entity the contents of a communication while in electronic
storage by that service.” (Italics added.) Similarly, and again subject to the same
exceptions, subsection (a)(2) declares that “a person or entity providing remote
computing service[21] to the public shall not knowingly divulge to any person or entity the
contents of any communication which is carried or maintained on that service . . . .”
(Italics added.) Finally, subsection (a)(3) bars any service provider from knowingly
divulging any non-content “record or other information pertaining to a subscriber or
customer” to any governmental entity.
The next two subsections of section 2702 — (b) and (c) — list exceptions to the
general prohibition on disclosure by a service provider set forth in subsection (a).
Subsection (b) describes eight circumstances under which a provider “may divulge the
contents of a communication.” As relevant here, subparts (1)-(3) of subsection (b) permit
disclosure: (1) “to an addressee or intended recipient of such communication or an agent
of such addressee or intended recipient”; (2) pursuant to section 2703, which, as
described below, permits a “governmental entity” to compel a covered provider to
disclose stored communications by search warrant, subpoena or court order; and
(3) “with the lawful consent of the originator or an addressee or intended recipient of
such communication, or the subscriber in the case of [a] remote computing service”
(italics added). As explained below, some of the communications sought under the
subpoenas at issue here may fall within the lawful consent exception set forth in section
2702(b)(3).22
21
The term “remote computing service” (RCS) is defined as “the provision to the
public of computer storage or processing services by means of an electronic
communications system.” (§ 2711(2).
22
The five other exceptions listed in section 2702(b) include disclosure incidental to
the provision of the intended service or protection of the rights or property of the service
provider; matters related to child abuse; and disclosure to a law enforcement agency of
inadvertently obtained information that appears to pertain to a crime.
23

Finally, subsection (c) of section 2702 describes six circumstances under which a
covered provider may divulge non-content information — that is, any “record or other
information pertaining to a subscriber or to a customer of such service (not including the
contents of communications. . . ).”23 As relevant here, the last of these exceptions
permits disclosure “to any person other than a governmental entity” (§ 2702(c)(6)) —
which includes defendants in this case.24


3. Rules governing compelled disclosure by a service provider to a

governmental entity: Section 2703
As alluded to above, section 2703 governs compelled disclosure by covered
providers to a “governmental entity.” It sets forth the rules under which law enforcement
entities may compel ECS and RCS providers to disclose private as well as public
communications made by users and stored by covered service providers.25
23
Such “non-content” records consist of logs maintained on a network server, as
well as “basic subscriber information,” including the following: “(A) name; [¶] (B
address; [¶] (C) local and long distance telephone connection records, or records of
session times and durations; [¶] (D) length of service (including start date) and types of
service utilized; [¶] (E) telephone or instrument number or other subscriber number or
identity, including any temporarily assigned network address; and [¶] (F) means and
source of payment for such service (including any credit card or bank account number).”
(§ 2703(c)(2).
24
The five preceding listed exceptions include disclosures of non-content
information (1) authorized under compulsion by a “governmental entity” under section
2703; (2) with the lawful consent of the customer or subscriber; (3) as necessary and
incidental to the provision of the intended service or protection of the rights or property
of the service provider; (4) self-initiated to a law enforcement agency under emergency
conditions; or (5) related to child abuse. (§ 2702(c).
25
(§ 2703(a) & (b).) As alluded to ante, footnote 23, subsection (c) addresses
compelled disclosure to a governmental entity of certain non-content information. Other
subsections articulate the requirements of any court order compelling disclosure
(§ 2703(d)), specify that there can be no cause of action against a provider who discloses
information pursuant to this chapter (§ 2703(e)), and impose on providers a requirement
to preserve evidence on request of a governmental entity “pending the issuance of a court
order or other process” (§ 2703(f)(1)).
24

C. House and Senate Reports Concerning the Relevant Provisions
The 1986 congressional reports took special note of then-existing electronic
bulletin boards — early analogues to the social media platforms at issue here. In the
course of these discussions, the respective judiciary committees focused on the
configuration of posts as being private or public and indicated an understanding that
section 2701, governing unauthorized access to communications, was intended to cover
and protect only private and not public posts. Significantly, the reports indicated the
same understanding regarding section 2702’s ban on provider disclosure of electronic
communications, as reflected in that section’s lawful consent exception to the ban.
The extensive House Report, issued first, repeatedly focused on the public/private
theme. It did so initially in a passage addressing section 2511(2) of the ECPA, which as
noted above states in subsection (g)(i) that it “shall not be unlawful” under either the
omnibus ECPA or its SCA subset to “access an electronic communication made through
an electronic communication system that is configured so that such electronic
communication is readily accessible to the general public.” The committee explained
that under this provision, it would be “permissible to intercept electronic communications
made through an electronic communication system that is configured so that such
electronic communication is readily accessible to the general public” and that “[t]he term
‘configure’ is intended to establish an objective standard of design configuration to begin
determining whether a system receives privacy protection.” (House Rep., supra, at
p. 41.) Later, when the report addressed the SCA’s analogue to this access rule, it
explained that section 2701 would not “hinder the development or use of ‘electronic
bulletin boards’ or other comparable services. The Committee believes that where
communications are readily accessible to the general public, the sender has, for purposes
of Section 2701(a), extended an ‘authorization’ to the public to access those
communications. A person may reasonably conclude that a communication is readily
accessible to the general public if the . . . means of access [is] widely known, and if a
25

person does not, in the course of gaining access, encounter any warnings, encryptions,
password requests, or other indicia of intended privacy. To access a communication on
such a system should not be a violation of the law.” (House Rep., supra, at p. 62, italics
added.) On the other hand, the report noted, some electronic bulletin boards may
provide, in addition to a public forum, private e-mail services — and it observed:
“Section 2701 would apply differently to the different services. Those . . . electronic
communications which the service provider attempts to keep confidential would be
protected, while the statute would impose no liability for access to features configured to
be readily accessible to the general public.” (Id., at p. 63, italics added.) The subsequent
Senate Report similarly focused on electronic bulletin boards and repeatedly echoed the
same public/private distinction. (Sen. Rep., supra, at pp. 8-9, 35-36.
The House Report next turned to the provision that we must construe here, section
2702, prohibiting disclosure by covered providers of communications contents. The
committee revealed its understanding that the theme of distinguishing between public and
private posts carried over from section 2701’s access rule and applied as well to section
2702’s bar on the divulging of communications by providers.
The report observed that although section 2702(a) articulates a general prohibition
on disclosure by a provider, section 2702(b)(3), setting out one of eight exceptions to that
rule, permits such a provider to divulge contents “with the lawful consent of the
originator or any addressee or intended recipient” of the communication. (House Rep.,
supra, at p. 66.) The committee explained that, in its view, implied lawful consent by a
user — and hence permissible disclosure by service providers — would readily be found
with regard to communications configured by the user to be accessible to the public. It
stressed that consent as contemplated by section 2702(b)(3) “need not take the form of a
formal written document of consent.” (Ibid.) The report viewed consent to disclosure as
being implied by a user’s act of posting publicly, and/or by a user’s acceptance of a
provider’s terms of service: “Consent may . . . flow from a user having had a reasonable
26

basis for knowing that disclosure or use may be made with respect to a communication,
and having taken action that evidences acquiescence to such disclosure or usee.g.,
continued use of such an electronic communication system.” (Ibid., italics added.) The
report explained that “[a]nother type of implied consent might be inferred from the very
nature of the electronic transaction. For example, a subscriber who places a
communication on a computer ‘electronic bulletin board,’ with a reasonable basis for
knowing that such communications are freely made available to the public, should be
considered to have given consent to the disclosure or use of the communication.” (Ibid.,
italics added.) Moreover, the report continued, “If conditions governing disclosure or use
are spelled out in the rules of an electronic communication service, and those rules are
available to users or in contracts for the provision of such services, it would be
appropriate to imply consent on the part of a user to disclosures or uses consistent with
those rules.” (Ibid., italics added.) In other words, the committee indicated its
understanding that with regard to electronic communications configured by the user to be
accessible to the public, a covered service provider would be free to divulge those
communications under section 2702(b)(3)’s lawful consent exception. Nothing in the
subsequent Senate Report took issue with this analysis. (Sen. Rep., supra, at pp. 36-38.
D. Cases Construing the SCA in Light of the House and Senate Reports
Prior decisions have found that Facebook and Twitter qualify as either an ECS or
RCS provider and hence are governed by section 2702 of the SCA.26 All parties assume
the same with respect to all three providers before us. We see no reason to question this
threshold determination.
26
See, e.g., Crispin v. Christian Audigier, Inc. (C.D.Cal. 2010) 717 F.Supp.2d 965,
987-990 (Crispin) [regarding Facebook posts and private messages]; Ehling v.
Monmouth-Ocean Hosp. Service Corp
. (D.N.J. 2013) 961 F.Supp.2d 659, 665-670
(Ehling) [implicitly concluding the same regarding Facebook posts].) A New York trial
court has implicitly reached the same conclusion regarding Twitter tweets. (People v.
Harris
(N.Y.Crim.Ct. 2012) 949 N.Y.S.2d 590, 596.
27

Only a few decisions have construed the relevant provisions of the SCA, and
nearly all have concerned civil litigation. Most have focused on claims that a party had
obtained unauthorized access to stored communications under section 2701, and hence
are not directly applicable here. Two decisions have addressed the question we face in
this criminal matter whether section 2702 bars covered service providers from
divulging social media communications in response to a subpoena. For context — and
because, as we will see, one of the key section 2702 disclosure cases subsequently relied
on some of the section 2701 access cases — it is useful to briefly address the access cases
before discussing the disclosure decisions.
1. “Unauthorized access” cases interpreting section 2701
Konop v. Hawaiian Airlines, Inc. (9th Cir. 2002) 302 F.3d 868 (Konop) concerned
asserted unauthorized access to communications on a restricted and password-protected
electronic bulletin board. The Ninth Circuit panel, citing some of the passages set out in
the two judiciary committee reports noted above, concluded that this legislative history
“suggests . . . Congress wanted to protect electronic communications that are configured
to be private, such as email and private electronic bulletin boards” and that Congress
intended the configuration of communications would “ ‘establish an objective standard
[for] determining . . . privacy protection.’ ” (Id., at pp. 875 & 879, fn. 8, quoting House
Rep., supra, at p. 41.) Subsequently, Snow v. Direct TV, Inc. (11th Cir. 2006) 450 F.3d
1314, quoted and extended Konop’s observation. The Eleventh Circuit concluded that in
light of section 2511(2)(g)(i) and some of the legislative history described earlier,
Congress intended to confine the reach of section 2701’s access bar to those stored
electronic communications that were configured to be restricted and not readily
accessible to the general public. (450 F.3d at pp. 1320-1321.
More recently, in Ehling, supra, 961 F.Supp.2d 659, a federal district court
addressed a party’s asserted unauthorized access to a user’s restricted Facebook posts.
The court highlighted the House Report’s understanding that the configuration of
28

communications would determine whether any given post is “accessible to the public”
(id., at p. 666), and it relied on section 2511(2)(g)(i) (permitting access to
communications that are “readily accessible to the general public”) as well as Konop and
Snow in concluding that “the SCA covers: (1) electronic communications, (2) that were
transmitted via an electronic communication service, (3) that are in electronic storage,
and (4) that are not public.” (Ehling, supra, at p. 667, italics added.) The court found
that Facebook “posts . . . configured to be private meet all four criteria.” (Ibid.) In
reaching this conclusion the court observed that decisions “interpreting the SCA confirm
that information is protectable as long as the communicator actively restricts the public
from accessing the information.” (Id., at p. 668, italics added.
The Ehling court elaborated: “The touchstone of the Electronic Communications
Privacy Act is that it protects private information. The language of the statute makes
clear that the statute’s purpose is to protect information that the communicator took steps
to keep private.” (Ehling, supra, 961 F.Supp.2d at p. 668.) It reasoned: “Facebook
allows users to select privacy settings . . . . Access can be limited to the user’s Facebook
friends, to particular groups or individuals, or to just the user. The Court finds that, when
users make their Facebook . . . posts inaccessible to the general public, [those] posts are
‘configured to be private’ for purposes of the SCA. . . . [W]hen it comes to privacy
protection, the critical inquiry is whether Facebook users took steps to limit access to the
information [in their posts]. Privacy protection provided by the SCA does not depend on
the number of Facebook friends that a user has.” (Ibid., italics added.)27
27
The court in Ehling observed that the plaintiff user had “approximately 300
Facebook friends” (961 F.Supp.2d at p. 662), and concluded that because she had
configured her communications as limited to them, the posts were covered by section
2701. (Ehling, at p. 668.) Nonetheless, the court ultimately rejected the plaintiff’s claim
of unauthorized access, finding that because an authorized recipient/friend had
voluntarily shared the plaintiff’s restricted communications with others, section 2701’s
“authorized user” exception was applicable. (Ehling, at pp. 669-671.
29

2. “Prohibited disclosure” cases interpreting section 2702
In addition to the civil decisions construing section 2701’s access rules and
recognizing a public/private distinction in that setting, a few civil cases have concerned
section 2702’s prohibition on disclosure, as applied to third party subpoenas designed to
compel providers to divulge electronic communications by the providers’ users.
a. O’Grady and related cases regarding subpoenas to providers seeking
e-mail communications
The first group of decisions addresses requests for disclosure by e-mail providers
of their users’ e-mail communications. A leading example is O’Grady, supra, 139
Cal.App.4th 1423, in which a California appellate court held section 2702 prevented an e-
mail service provider from complying with a subpoena issued on behalf of Apple
Computer (Apple). Apple sought the e-mail communications of an online news
magazine to discover the identities of those who leaked confidential information about an
impending Apple product. In concluding that section 2702 prohibited disclosure by the
provider of such private e-mails (O’Grady, at pp. 1440-1451), the court distinguished
between public posts that were made available “to the world,” and the “contents of
private [e- mail] messages” at issue in that case. (Id., at p. 1449, italics omitted.) The
court noted that it would reach a different conclusion, and presumably find disclosure
permissible, “if the discovery [could] be brought within one of the statutory exceptions
— most obviously, a disclosure with the consent of a party to the communication” under
the lawful consent exception of section 2702(b)(3). (O’Grady, at p. 1446; see also id., at
p. 1447.) Likewise, other courts have concluded that section 2702 bars e-mail service
providers from divulging private e-mail communications in response to third party civil
subpoenas when, as in O’Grady, no exception to the Act’s prohibitions on disclosure is
applicable. (See, e.g., In re Subpoena Duces Tecum to AOL, LLC (E.D.Va. 2008) 550
F.Supp.2d 606, 611 [“[a]greeing with the reasoning in O’Grady” and declining to enforce
30

a subpoena seeking production of private e-mail communications absent an applicable
exception to the prohibition on disclosure].
b. Viacom and Crispin — regarding subpoenas served on providers
seeking social media communications
Two additional section 2702 disclosure cases are more pertinent to our present
inquiry because they concerned disclosure by service providers, not of private e-mail, but
of social media communications. As explained below, these decisions reflect an
understanding that Congress intended section 2702 to prohibit disclosure by providers of
only private or restricted, but not public, social media communications.
The first opinion, Viacom Int’l Inc. v. YouTube Inc. (S.D.N.Y. 2008) 253 F.R.D.
256, addressed efforts by copyright owners to compel a social media provider, YouTube,
to divulge stored information regarding videos that users had configured as private or
restricted. (Id., at p. 264.) The federal district court quoted the House Report’s
observation, noted ante, part II.C., that one who posts a communication with a reasonable
basis for knowing that it will be available to the public should be considered to have
implicitly consented to such disclosure under section 2702(b)(3). (253 F.R.D. at p. 265.
The court held, however, that YouTube was barred under section 2702(a) from disclosing
“videos that [users] have designated as private and chosen to share only with specified
recipients” — and that on the facts presented, section 2702(b)(3)’s lawful consent
exception was inapplicable. (Viacom, at pp. 264-265.
The second decision, Crispin, supra, 717 F.Supp.2d 965, also concerned
disclosure by a social media service provider under section 2702 in response to a civil
discovery subpoena. The plaintiff in Crispin, an artist, sued the defendants, clothing
manufacturers, asserting they violated a license to use his art. The defendants in turn
issued subpoenas to various service providers, including Facebook and social media
provider MySpace. The subpoenas broadly sought all manner of communications,
ranging from public to private, between the plaintiff and others. The plaintiff moved to
31

quash the subpoenas on various grounds, including that the providers were barred by
section 2702 from making the disclosures. A magistrate concluded that the section did
not apply, and declined to quash the subpoenas with respect to any of the
communications.
On review, the district court, relying on the legislative history of the SCA and the
decision in Konop, supra, 302 F.3d 868, discussed above, determined first that so-called
“private messaging” communications, like the e-mails in Konop, were configured to be
private and hence protected from disclosure by service providers under section 2702(a).
(Crispin, supra, 717 F.Supp.2d at p. 987.) Turning to the other communications,
Facebook posts and MySpace comments, the court analogized those communications to
the technology that existed in 1986 — postings on a “ ‘computer bulletin board’ ” system.
(Id., at p. 980.) The court concluded that “a completely public [bulletin board system]
does not merit protection under the SCA” — and that “ ‘[o]nly electronic bulletin boards
which are not readily accessible to the public are protected under the Act.’ ” (Id., at
p. 981, italics added.) In other words, the court determined that Facebook posts and
MySpace comments configured by registered users to be public are not protected from
disclosure under section 2702(a) of the Act. But, the court reasoned, those
communications would not be subject to disclosure by a provider if the user, like users of
older restricted-access electronic bulletin boards, had configured the post or comment to
be accessible only by a restricted group. (Crispin, at p. 981.
Accordingly, the court in Crispin determined that the dispositive question was
whether the posts had been configured by the user as being “sufficiently restricted that
they are not readily available to the general public.” (Crispin, supra, 717 F.Supp.2d at
p. 991.) Further, the court found that any restrictive privacy configuration employed by
the user should be honored, and would bar disclosure by a service provider under
32

section 2702 of the SCA, even if the restricted group is comprised of all of a user’s
Facebook friends. (Crispin, at p. 990.)28
Applying these principles to the motion to quash the civil subpoenas before it, the
Crispin court observed that the parties had provided an incomplete record regarding the
nature of the various private message services and other posts and comments services
offered by those social media entities. Accordingly, the court remanded the matter “so
that [the magistrate] can direct the parties to develop a fuller evidentiary record regarding
plaintiff’s privacy settings and the extent of access allowed to his Facebook [posts] and
MySpace comments.” (Crispin, supra, 717 F.Supp.2d at p. 991.
The gist of Crispin’s discussion and treatment was that communications
configured by the user to be restricted in some manner fall within section 2702’s
prohibition on disclosure by providers and are not subject to a civil subpoena directed to
those providers. On the other hand, the subpoenas would be enforceable to the extent
they sought Facebook posts and MySpace comments that had been configured by the
registered user to be publicly accessible.
In reaching these conclusions Crispin relied heavily on the SCA’s access
provisions and related case law — and it focused generally on section 2702’s disclosure
bar without also considering specifically the lawful consent exception set out in section
2702(b)(3). Accordingly, the decision can be read as concluding that if Congress
intended to withhold liability under section 2701 concerning those who access public
28
The Crispin court reasoned: “Although here a large number of [registered] users,
i.e., all of plaintiff’s Facebook friends, might access the storage and attendant
retrieval/display mechanism, the number of users who can view the stored message has
no legal significance. Indeed, basing a rule on the number of users who can access
information would result in arbitrary line-drawing and likely in the anomalous result that
businesses such as law firms, which may have thousands of employees who can access
documents in storage, would be excluded from the statute.” (Crispin, supra, 717
F.Supp.2d at p. 990.
33

communications, Congress must also have intended not to protect those same public
communications from disclosure by covered providers under section 2702. Under this
view, which appears to have been endorsed by some commentators,29 the Act simply
would not cover or protect communications that have been configured to be public. We
do not endorse this reading of the Act, however. Instead, we conclude that, by virtue of
section 2702(a), the Act generally and initially prohibits the disclosure of all (even
public) communications — but that section 2702(b)(3)’s subsequent lawful consent
exception allows providers to disclose communications configured by the user to be
public. Thus, although we agree with the result in Crispin, we conclude that the decision
in that case should have been grounded on the lawful consent exception to the general
prohibition.
As observed ante, part II.C., the House Judiciary Committee discussed the
public/private distinction articulated under section 2511(2)(g)(i) of the ECPA, and
revealed that it viewed that same distinction as carrying over and applying under the
related access provision of the SCA, section 2701. The House Report then proceeded to
describe the disclosure provision, section 2702, in a manner showing that it considered
the same public/private distinction to apply in that context as well via the lawful consent
29
See, e.g., Discovering Facebook, supra, 24 Harv.J.L. & Tech. at page 584 [“Under
the SCA, information that is ‘readily accessible to the general public’ is not protected
from disclosure”]; Hankins, Compelling Disclosure of Facebook Content Under the
Stored Communications Act
(2012) 17 Suffolk J. Trial & App. Adv. 296, 314, 319 [“case
law has made clear that communications that are ‘readily accessible’ by the public are not
protected by the SCA”; “where a user’s privacy settings allow the general public to view
such communications, it is clear that the SCA will not govern such ‘readily accessible’
communications”; and when comments can be “viewable by anyone with internet access”
they “would not be protected by the SCA”]; see also Comment, Balancing the Scales of

would not be covered under the SCA”].

exception contained in section 2702(b)(3). We conclude that the Crispin decision
properly focused on the user’s configuration of communications, and it also reached the
correct result — even though it did not explicitly rely, as it should have, on the lawful
consent exception and legislative history illuminating that exception.30
E. Conclusion Regarding Section 2702(b)(3)’s Lawful Consent Exception
In light of the foregoing analysis, we conclude that communications configured by
a social media user to be public fall within section 2702(b)(3)’s lawful consent exception,
presumptively permitting disclosure by a provider.
30
We also briefly note a recent Tennessee intermediate appellate court decision,
State v. Johnson and Williams (Tenn.Crim.App. 2017) 538 S.W.3d 32 (Johnson). That
litigation, like the present case, arose pretrial in a criminal prosecution. A percipient
witness told the police that various “social media communications” concerning the events
had been sent and received by her, as well as the victim and other friends of the victim,
and both defendants, before and after the alleged offenses occurred. (Id., at p. 38.) One
of two defendants issued subpoenas to, among others, the relevant social media service
providers, broadly seeking all such communications. The state — but not the providers
— moved to quash the subpoenas. (Id., at pp. 44-48.) The trial court denied the state’s
motion as to the providers, finding that the state lacked standing to object on their behalf.
(Id., at pp. 47-49.) On review the appellate court agreed and then proceeded, in dictum,
to address matters that might arise on remand.
The court described the evolution of the SCA, extensively quoted sections 2701,
2702 and 2703, and briefly discussed some of the cases cited above, including Crispin.
(Johnson, supra, 539 S.W.3d at pp. 63-69.) The appellate court next focused solely on
section 2703, which as noted earlier concerns a governmental entity’s authority to compel
disclosure from providers. (Johnson, at pp. 69-70.) The court observed that the
underlying defendants did not qualify as governmental entities — and from there jumped
to the broad conclusion that the defendants “could not obtain” pursuant to their
subpoenas “any information directly from the social media providers under the terms of
the SCA.” (Id., at p. 70, italics added.) In proceeding as it did, the Johnson court’s
dictum failed to consider the legislative history outlined above, the scope of section
2702’s disclosure bar, or the lawful consent exception to that bar. As a result, the court
failed to consider whether any of the sought social media communications had been
configured by the users to be public, and thus were disclosable by the providers pursuant
to the defense subpoenas.
35

III. APPLICATION TO THIS CASE
A. Overview: The Parties’ General Agreement in Their Supplemental Briefs
That Public Communications May Be Disclosed Under the Lawful
Consent Exception; Limitation of Our Analysis to That Statutory Issue;
and the Need for Remand to the Trial Court

As alluded to earlier, in supplemental briefs concerning section 2702 filed in
response to questions posed by this court, both parties now agree that a social media
communication configured by a registered user to be public falls within section
2702(b)(3)’s lawful consent exception.31 In reaching this conclusion, providers retreat
from their assertions that no exception to the prohibition applies with respect to any of
the sought communications. Providers concede that, based on the legislative history
described earlier, “[w]hen a user chooses to make a communication freely accessible to
the public, he or she has necessarily consented to its disclosure.” Accordingly, providers
acknowledge that “as applied to communications that are available to the public, [section
2702(b)(3)’s] lawful consent exception allows a provider to disclose communications to
any member of the public.”
31
In their supplemental brief, providers initially maintain that defendants’ failure to
challenge providers’ proposed statutory interpretation in the lower courts precludes this
court from addressing the propriety of that statutory interpretation at this juncture. We
reject this contention. It is this court, not defendants, that has raised issues different from
those argued below. When this court discovers a possible statutory interpretation
question that may obviate the need to address a constitutional claim and solicits
supplemental briefing on that issue, the statutory interpretation question is properly
before us for resolution. (See Rules of Court, rule 8.516(b)(2) [“The court may decide an
issue that is neither raised nor fairly included in the petition or answer if the case presents
the issue and the court has given the parties reasonable notice and opportunity to brief
and argue it”].) Here we are guided by the familiar principle that we should address and
resolve statutory issues prior to, and if possible, instead of, constitutional questions (see,
e.g., Santa Clara County Local Transportation Authority v. Guardino (1995) 11 Cal.4th
220, 230-231, and cases cited), and that “we do not reach constitutional questions unless
absolutely required to do so to dispose the matter before us.” (People v. Williams (1976
16 Cal.3d 663, 667, and cases cited.
36

Nevertheless, both parties urge us to address not only the scope of the lawful
consent exception, but also the constitutional issues originally framed and briefed. As
alluded to in footnote 31, and as explained below, we find it proper at this point to
address only the statutory issues, and not the constitutional claims.
As observed earlier, in the lower court proceedings the parties did not focus on the
public/private configuration distinction. The trial court made no determination whether
any communication sought by defendants was configured to be public (that is, with
regard to the communications before us, one as to which the social media user placed no
restriction on who might access it) or, if initially configured as public, was subsequently
reconfigured as restricted or deleted. Nor is it clear that the trial court made a sufficient
effort to require the parties to explore and create a full record concerning defendants’
need for disclosure from providers — rather than from others who may have access to the
communications. Consequently, at this point it is not apparent that the court had
sufficient information by which to assess defendants’ need for disclosure from providers
when it denied the motions to quash and allowed discovery on a novel constitutional
theory. In any event, because the record is undeveloped, we do not know whether any
sought communication falls into either the public or restricted category — or if any
initially public post was thereafter reconfigured as restricted or deleted.
In light of our interpretation of the Act, it is possible that the trial court on remand
might find that providers are obligated to comply with the subpoenas at least in part.
Accordingly, although we cannot know how significant any sought communication might
be in relation to the defense, it is possible that any resulting disclosure may be sufficient
to satisfy defendants’ interest in obtaining adequate pretrial access to additional
electronic communications that are needed for their defense. For these reasons, we will
not reach or resolve defendants’ constitutional claims at this juncture. Instead, we
conclude that a remand to the trial court is appropriate.
37

In order to provide guidance to the trial court on remand, we discuss two issues
regarding the statutory question that have been raised by the parties in their supplemental
briefs.
B. Defendants’ Contention That Implied Consent to Disclosure by a Provider
Is Established When a Communication Is Configured by the User to Be
Accessible to a “Large Group” of Friends or Followers

The parties now generally agree that communications configured by a social
media user to be public fall within section 2702(b)(3)’s lawful consent exception and
presumptively may be disclosed by a provider. Beyond this point of agreement, the
parties disagree starkly concerning the proper scope and interpretation of the implied
consent exception.
Defendants advance an expansive interpretation of the exception. They argue that
a user’s implied consent to disclosure by providers under section 2702(b)(3) should be
triggered not only by communications configured by the user to be public, but also by
those configured by the user to be restricted, but nonetheless accessible to a “large
group” of friends or followers. Defendants contend that, in practice, social media users
“lose[] control over dissemination once the information is posted,” and can have no
reasonable expectation of privacy even with regard to such restricted communications in
light of the fact that any authorized recipient can easily copy any communication and
share it with others. (Cf. Moreno v. Hanford Sentinel, Inc. (2009) 172 Cal.App.4th 1125,
1229-1230 [social media user had no reasonable expectation that a communication
configured as restricted would not be shared with others and hence could not maintain a
tort action for public disclosure of private facts].) Defendants observe that the internet,
attendant technology, and social media itself did not exist when Congress considered and
enacted the SCA. (See ante, fn. 18.) Therefore, they assert, section 2702 of the Act,
generally prohibiting providers from disclosing stored communications, “should be
38

deemed inapplicable” on the ground that “social media posts to large groups are
essentially public posts in which the user has no reasonable expectation of privacy.”
In support, defendants rely primarily on distinguishable decisions finding social
media communications discoverable in civil litigation from a social media user, not, as
here, from a social media provider. (E.g., Fawcett v. Altieri (N.Y.Sup.Ct. 2013) 960
N.Y.S.2d 593, 597 [private social media posts may be compelled from a user in civil
discovery “just as material from a personal diary may be discoverable”].) They also rely
on cases such as U. S. v. Meregildo (S.D.N.Y. 2012) 883 F.Supp.2d 523, 526 (Meregildo
[rejecting Fourth Amendment claim and holding that a criminal defendant who restricted
Facebook communications to “friends” had no legitimate expectation that a friend would
not share that information with the government].) But none of these cases involving the
propriety of compelling disclosure by social media users concerned or construed section
2702’s prohibition on disclosure by providers.
Defendants criticize decisions such as Crispin, supra, 717 F.Supp.2d 965, and
Ehling, supra, 961 F.Supp.2d 659, for analogizing social media communications to what
they characterize as “nearly obsolete” electronic bulletin boards. They insist that
focusing on such allegedly outdated sites prevented those courts from understanding that
sharing is the essence of modern social media. Indeed, defendants and amici curiae on
their behalf argue that, in the context of social media communications, there generally is
no such thing as true privacy. Accordingly, they assert, even those social media
communications configured by a user to be available to only specific friends or followers
and that exhibit a “veneer of privacy” should nevertheless be treated as public.
Defendants argue that such communications should not be protected by section 2702(a
— or that, alternatively, they should be deemed to fall within the lawful consent
exception of section 2702(b)(3).
Providers and amicus curiae Google, LLC (Google), by contrast, assert that a
registered user who configures a communication to be viewed by any number of friends
39

or followers — but not by the public generally — evinces an intent not to consent to
disclosure by a provider under 2702(b)(3), but instead to preserve some degree of
privacy. They too rely on Meregildo, supra, 883 F.Supp.2d 523, 525, which observed
that Facebook “postings using more secure privacy settings reflect the user’s intent to
preserve information as private.” They also rely on Ehling, supra, 961 F.Supp.2d at
page 668, which, as noted earlier, focused on whether a Facebook user “actively
restrict[ed] the public from accessing information” and found that when a user configures
a communication to be available on only a limited basis and “inaccessible to the general
public,” such a post is “ ‘configured to be private’ for purposes of the SCA.” Under this
authority, providers assert, a service provider remains prohibited from disclosing such
communications. For reasons that follow, we agree with providers and Google on this
point.
To begin with, we reject defendants’ unsupported and rather startling assertion that
social media communications and related technology fall categorically outside section
2702(a)’s general prohibition against disclosure by providers to “any person or entity.”32
32
For similar reasons we reject a somewhat related alternative interpretation of that
quoted phrase advanced by amici curiae on behalf of defendants, the California Public
Defenders’ Association and the Public Defender of Ventura County. Asserting that the
phrase “any person or entity” in section 2702(a) should be interpreted to exclude a court,
amici curiae propose to interpret that phrase to permit providers to disclose any and all
stored communications (no matter how configured) to a trial court for its in camera
review — and then, presumably, for the trial court to release at least some of those
private communications to defendants.
In support of their argument that a trial court does not qualify as a person or entity
under the statute, amici curiae simply cite Marbury v. Madison (1803) 5 U.S. 137. They
argue that Congress must be presumed to have been aware of “existing law” (including
Penal Code section 1326’s in camera review procedures) as well as the Fifth and Sixth
Amendment rights of defendants — and hence, they postulate, Congress must have
contemplated that such an exception for in camera and ex parte review by a trial court
would be “read into the Act” by the courts, “when and if,” as here, “the need arises.”
Amici curiae add that “Congress . . . knows that the courts are the forum where
controversies such as the one here will be resolved and that the courts will determine
their own procedures” — including amici curiae’s contemplated compelled compliance
40

Nor can we accept defendants’ interpretation of section 2702(b)(3)’s lawful consent
exception, which would sweep far more broadly than was envisioned by Congress. The
legislative history suggests that Congress intended to exclude from the scope of the
lawful consent exception communications configured by the user to be accessible to only
specified recipients. There is no indication in the legislative history of any intent to do
otherwise in the case of communications sent by a user to a large number of recipients
who, even in 1986 when the Act was adopted, could have shared such communications
with others who were not intended by the original poster to be recipients.
In this respect, providers argue, defendants’ view “would effectively eliminate
expectations of privacy in all communications” and hence “would undermine the privacy
rights of all users, including those of criminal suspects and defendants. If the SCA
excluded electronic communications that are made to [‘large’] groups of people, then it
would necessarily place no restriction on private party or law enforcement access to such
communications. And if people had no reasonable expectation of privacy in
communications sent through and maintained by the intermediary, simply because those
communications could be later shared by their recipients, that would remove all Fourth
Amendment protections for communications as well.” (Italics in original.) Providers
assert there is no indication that Congress contemplated such a result.33
with in camera review by the trial court. Finally, amici assert that to the extent the Act
“is interpreted to prohibit [in camera] judicial assessment of the exculpatory significance
of the subpoenaed records,” the SCA, as applied in this case, violates defendants’ Fifth
and Sixth Amendment rights, and hence is unconstitutional. Putting aside the
constitutional claim, neither the statutory language nor its legislative history supports
amici curiae’s claim that the statute can reasonably be interpreted to permit disclosure of
all electronic communications, private or public, to a court under all circumstances.
33
Moreover, as amicus curiae Google notes, if defendants’ “premise were correct, a
communication shared with only one person would be equally public because a single
recipient could share a private communication with the world (and some recipients
do). . . . The ability to share an electronic communication accordingly cannot be the basis
41

As observed ante, part II.C., the House Judiciary Committee suggested, in its
discussion of access rules, an understanding that a user’s configuration would “establish
an objective standard” to determine privacy protection. When subsequently addressing
the disclosure rules — and the lawful consent exception to those rules — the House
committee stressed that a user’s consent to disclosure could be implied in view of, among
other things, providers’ available published policies. (House Rep., supra, at p. 66.
Providers’ posted policies and answers to frequently asked questions (FAQs), described
below, are readily available, and they appear to shed light on the issues presented in this
litigation. Although we will highlight and quote some of these available policies and
FAQs, we emphasize that in doing so we do not preclude any party from advancing any
additional point or argument — including the legal significance that should or should not
be accorded such policies and FAQs.
The policies and FAQs warn registered users that a communication configured as
public will generally become, in the words of the House Report, supra, at page 62,
“readily accessible to the general public,” and available to any person via the internet,
whether that person is registered with the social media provider, or not.34 This
for removing privacy protections from content posted with less-than-public privacy
settings.”

widespread availability of public posts on the internet is the result of providers’ business
model, which allows and facilitates crawling and indexing by search engines (and in
some instances, use of a so-called firehose stream) that generate search results lists
displaying a link to the user’s current social media page, a title and a snippet of text.35 In
other words, when, for example, a Facebook user configures a post as public, that
communication becomes both (a) available to all two billion registered Facebook users,
and (b) again in the words of the House Report, “readily accessible to the general public”
via crawling by search engines. The result is that, as counsel for providers conceded at
oral argument, a public communication is available to “everyone in the world” — even to
those who are not registered Facebook users, but who have open access to the internet.
Providers’ FAQs warn that even communications configured as restricted still
might be shared by an authorized recipient with anyone else.36 At the same time, nothing

Definition of Twitter fire hose <http://lexicon.ft.com/Term?term=Twitter-fire-hose> [as
of May 22, 2018].
In addition, the three largest search engines — Google, Bing, and Yahoo! — also
display in their results a link to a cached version of the social media user’s page. (See,
e.g., Google, Search Help/View webpages cached in Google Search Results/How to get a
cached link
<https://support.google.com/websearch/answer/1687222?hl=en> [as of
May 22, 2018].) Google explains that “[c]ached links show you what a webpage looked
like the last time Google visited it” and that “Google takes a snapshot of each webpage as
a backup in case the current page isn’t available. . . . If you click on a link that says
‘Cached,’ you’ll see the version of the site that Google stored. (Ibid.
36
Even with regard to communications that a user configures — either initially when
sent, or subsequently as reconfigured — to be available to only a defined group (such as
followers or friends), any such restriction operates only within the confines of the service
and the licensing agreements under which other entities interact with the provider.
Providers are generally careful to avoid describing the effect of privacy configuration
more broadly. (See, e.g., Facebook Help Center, When someone re-shares something I
posted, who can see it?
<https://www.facebook.com/help/569567333138410> [as of
43

of which we are aware in any of providers’ policies or answers to FAQs suggests that
users would have any reason to expect that, having configured a communication to be
available not to the public but instead to a restricted group of friends or followers, the
user nevertheless has made a public communication — and hence has impliedly
consented to disclosure by a service provider, just as if the configuration had been public.
May 22, 2018] [“When someone clicks Share below your post, they aren’t able to share
your photos, videos or status updates through Facebook with people who weren’t in the
audience you originally selected to share with
” (italics added, boldface omitted).]
Accordingly, when a user configures a post to be available to only specifically
listed persons, the provider will be able to honor that user’s choice only within the service
— by disabling those recipients from, in turn, sharing that communication with others
within the system through the system’s sharing tools. Moreover, all three providers warn
users that such configuration protection within each system does not prevent any
authorized recipient from employing mechanisms outside the system to copy any post
(by, for example, downloading or creating a screen shot) and then sharing the
communication with anyone on the internet. (See, e.g., Twitter, About public and
protected Tweets/Who can see my Tweets?
<https://support.twitter.com/articles/14016>
[as of May 22, 2018] [“Keep in mind that when you choose to share content on Twitter
with others, this content may be downloaded or shared”].) Indeed, as Twitter advises,
even when a user protects communications by restricting them to specific persons, that
user’s communications might nevertheless be shared by any such person with anyone
else. (Twitter Help Center, Twitter Privacy Policy/Information Collection and
Use/Direct Messages and Non-Public Communications

44

For all of these reasons we reject defendants’ proposed broad interpretation of the
lawful consent exception. We hold that implied consent to disclosure by a provider is not
established merely because a communication was configured by the user to be accessible
to a “large group” of friends or followers.37
C. Providers’ Argument That Section 2702 Affords a Provider Discretion to
Decline to Comply with a Valid State Subpoena

Providers contend that to the extent section 2702(b)(3)’s lawful consent exception
applies to any of the communications at issue here, that provision simply authorizes them
to comply with the subpoenas, but does not by itself compel them to comply with the
subpoenas. They further assert that section 2702(b) affords providers who are authorized
to disclose, the “discretion” to refuse to do so — even in the face of an otherwise proper
subpoena lawfully issued under state law. We agree with the first proposition, but not
with the second.
37
At the same time, we do not endorse the view, expressed by counsel for providers
at oral argument, that if it were possible for a registered Facebook user to restrict a
communication to “only” all of the other two billion Facebook users, such a
communication would not qualify as public under the Act. To our knowledge, no case
has endorsed that view and on its face the claim seems rather questionable, particularly
inasmuch as Facebook does not generally limit who may join its social media platform.
In this regard, we note that what is public under the SCA is not defined by what a social
media provider labels as “public.”
Nor are we aware of any prior case involving a user who has placed minimal
restrictions on a communication within a large social media service (as another
hypothetical example, a user who might disseminate a communication to all two billion
Facebook users except for one or two people). Although we hold that limiting a
communication to a “large group” does not render a post public, and acknowledge that on
remand the trial court might find that the public configurations at issue in this case render
the resulting communications public under the SCA, we also observe that neither the
hypothetical discussed at oral argument nor this additional hypothetical involving
minimal restrictions is presented in this case. Therefore, we need not and do not resolve
whether such communications would be sufficiently public to imply consent to disclosure
under section 2702(b)(3).
45

As observed earlier, section 2702(a) sets out a general prohibition against
disclosure of communications by a service provider; and section 2702(b) lists exceptions
under which a provider “may” disclose such communications — including, in subsection
(3), communications regarding which a user has lawfully consented to disclosure. As the
parties have conceded, such consent is applicable when a user posts a communication
configured to be public. Plainly, section 2702(b) merely permits a provider to disclose,
and it does not by itself impose a duty or obligation to disclose. Yet providers maintain
that by use of the word “may,” the section also operates to “ensure that providers would
retain the discretion to choose whether to disclose content based on a user’s consent” —
even in the face of a lawful subpoena. In support, they rely on language in an order by a
federal magistrate judge, In re Facebook, Inc. (N.D. Cal. 2012) 923 F.Supp.2d 1204,
1206, stating that although “consent may permit production by a provider, it may not
require such a production.” (Italics in original, boldface omitted.) Providers also rely on
that order’s footnote 7, which cited United States v. Rodgers (1983) 461 U.S. 677, 706
for the general proposition that “[t]he word ‘may,’ when used in a statute, usually implies
some degree of discretion.”
As explained below, a California Court of Appeal decision, Negro v. Superior
Court (2014) 230 Cal.App.4th 879 (Negro), has thoroughly considered and rejected
providers’ argument. In that litigation, the plaintiff sued multiple defendants concerning
business transactions. Prior to trial, the plaintiff subpoenaed defendant Negro’s e-mail
service provider, Google, seeking e-mail communications between him, his codefendants,
and others. Defendant Negro eventually expressly consented to disclosure by Google of
e-mails between himself and specific persons and entities covering a defined range of
dates. But despite its user’s express consent, Google refused to comply with the civil
subpoena. On review, the Court of Appeal considered and applied section 2702(b)(3)’s
lawful consent exception, ultimately finding that the defendant had given his express and
enforceable written consent to service provider Google’s disclosure of his e-mails.
46

(Negro, at pp. 893-899.) Having found the lawful consent exception satisfied, the
appellate court further concluded that the subpoena was itself enforceable and that
Google was required to comply with it. In the process, the court carefully considered and
rejected the contention that providers raise now — that the statute empowers providers to
defy subpoenas seeking communications that are exempted from section 2702’s
prohibition on disclosure under the section’s lawful consent exception. (Id., at pp. 899-
904.) Because we find the Negro court’s reasoning persuasive, we quote that decision’s
analysis at some length.
As an initial matter, the court in Negro, supra, 230 Cal.App.4th 879, rejected the
claim that the SCA confers “a blanket exemption or immunity on service providers
against compulsory civil discovery process.” (Id., at p. 899.) The court acknowledged
that the SCA does not, on its face, contain any exception for or mention of civil (or for
that matter criminal) discovery subpoenas. But the court explained that the Act’s failure
to expressly include such subpoenas does not “suggest that it rendered” the normal state
law “discovery process impotent in all circumstances.” (Ibid.)38
Turning to the same argument reprised by providers here, the court in Negro
addressed Google’s assertion “that the language of the Act makes the consent exception
‘permissive’ and the provider’s disclosure under it ‘voluntary’ . . . so that ‘Google may
not be compelled by an order issued in a civil proceeding to disclose content, even with
38
The court continued: “Nor do we . . . perceive anything in the language of the Act
suggesting that Congress intended to grant service providers a blanket immunity from
obligations imposed by discovery laws. The Act does not declare civil subpoenas
unenforceable; it does not mention them at all. As we have said, it preempts state
discovery laws insofar as they would otherwise compel a service provider to violate the
Act.
It is this preemption that excuses service providers from complying with process
seeking disclosures forbidden by the Act. But nothing in the Act suggests that service
providers remain shielded from state discovery laws when the disclosures sought are not
forbidden by the Act.” (Negro, supra, 230 Cal.App.4th at p. 900, fn. omitted, first italics
added, subsequent in original.
47

the user’s consent.’ ” (Negro, supra, 230 Cal.App.4th at p. 900.) The appellate court
observed that Google relied on section 2702(b)’s “use of the word ‘may’ to frame the
exception for disclosure based on a user’s consent,” and on the passage quoted above
from the federal magistrate’s order in In re Facebook, Inc., supra, 923 F.Supp.2d at page
1206. (Negro, at p. 900.) The court determined that the magistrate’s reasoning “places
much more weight on a very small word than it is designed to bear. It is certainly true
that ‘may’ generally conveys permission, and that when used in contradistinction to
‘shall’ it implies a discretionary power or privilege, as distinguished from a mandatory
duty. [Citations.]” (Id., at p. 901.) But, the court reasoned, “The subdivision where
‘may’ appears is framed not as a grant of discretionary power or as the imposition of a
mandatory duty but as a special exception to a general prohibition. In such a context all
‘may’ means is that the actor is excused from the duty, liability, or disability otherwise
imposed by the prohibition. Stating that the actor ‘may’ engage in the otherwise
proscribed conduct is a natural way — indeed the most natural way — to express such an
exception.” (Id., at p. 902, italics in original.
The appellate court in Negro continued: “Another federal magistrate judge has
observed that ‘there should be a clear expression of congressional intent before relevant
information essential to the fair resolution of a lawsuit will be deemed absolutely and
categorically exempt from discovery and not subject to the powers of the court under
[rules governing disclosure].” [Citation.] Congress’s use of the word ‘may’ to frame an
exception to the Act’s general prohibition on disclosure is not such a ‘clear expression
of . . . intent’ as will justify a reading of the Act that categorically immunizes service
providers against compulsory civil process where the disclosure sought is excepted on
other grounds from the protections afforded by the Act.” (Negro, supra, 230 Cal.App.4th
at p. 902.
Finally, the appellate court concluded: “In sum, we find no sound basis for the
proposition that the Act empowers service providers to defy civil subpoenas seeking
48

discovery of materials that are excepted from the Act’s prohibitions on disclosure.
Insofar as the Act permits a given disclosure, it permits a court to compel that disclosure
under state law.” (Negro, supra, 230 Cal.App.4th at p. 904.) Accordingly, the court held
that in light of the fact that the user/defendant had consented to disclosure by the service
provider, “the Act does not prevent enforcement of a subpoena seeking materials in
conformity with the consent given.” (Ibid.
Providers do not directly address the logic or substance of the Negro court’s
analysis quoted above. Instead, they assert, first, that the appellate court’s decision is
distinguishable because the underlying lawful consent in that case was express, whereas
the present case concerns implied consent. This attempt to avoid Negro’s analysis
ignores the legislative history described ante, part II.C., disclosing that Congress
specifically contemplated that implied lawful consent would satisfy the lawful consent
exception. It also is in tension with providers’ own concession that implied lawful
consent is effective with regard to communications configured by a registered user to be
public. (See ante, pt. III.A.
Alternatively, providers suggest that the SCA should be interpreted to bar the
enforcement of any state subpoena that directs service providers to divulge public
communications that the Act permits but does not require them to disclose. They assert
that Negro’s contrary analysis and conclusion must be wrong because “it would permit a
state subpoena to compel disclosure of content where the SCA itself does not. Such an
expansion would weaken the protections of the SCA and impermissibly broaden federal
law. It would thereby conflict with the SCA’s comprehensive scheme of regulating the
circumstances under which the disclosure of content is permissible or required.”
In this respect providers implicitly rely on the fact that section 2703 lists
circumstances in which a provider is compelled to disclose to governmental entities —
and yet, as the Negro court observed, the Act, although preempting state discovery laws
that would compel a provider to violate the federal statute, “does not mention” civil (or
49

criminal) subpoenas issued by nongovernmental entities in that section or indeed at all.
(Negro, supra, 230 Cal.App.4th at p. 900; see ante, fn. 38.) Consistently with Negro’s
analysis, we believe that if Congress intended to preclude a state from enforcing a
nongovernmental entity’s civil or criminal subpoena that is lawful under state law (and as
to which the federal statute does not preclude disclosure), such a prohibition would have
been made clear in the Act. We find no intent by Congress to preempt state law in this
setting.39
D. Additional Issues Raised in the Supplemental Briefs, Some of Which
Should Be Explored and Resolved on Remand to the Trial Court

Having addressed the legal issues that can be decided on the present record, we
turn to other matters raised in providers’ briefs that cannot be resolved at this stage —
and some of which must await exploration on remand.
1. Providers’ assertion that most of the communications at issue are private
and hence the lawful consent exception will not assist defendants
As observed earlier, the subpoenas in this case broadly seek “any and all public
and private content.” Providers in their supplemental briefs assert variously that “much”
or “most” (or all except a “small subset”) of the communications sought by the subpoenas
were configured by the users to be private or restricted, not public, and hence the lawful
consent exception generally will not assist defendants in this case. Because the parties
did not acknowledge the relevance and applicability of the lawful consent exception in
the trial court, no reliable record was made concerning either registered user’s
configuration of the social media communications at issue here.40 Moreover, as noted
39
To the extent dictum in Johnson, supra, 538 S.W.3d 32, is inconsistent (see ante,
fn. 30), we disagree with its approach and analysis.
40
At the time relevant in this case, it appears that each provider’s default setting for
registered users was public, meaning that unless the user configured communications to
be private, they were public. (Regarding Twitter, see Twitter Privacy Policy/Information
Collection and Use/Tweets, Following, Lists, Profile, and other Public Information

50

earlier, it is not apparent that the trial court had sufficient information to fully assess
defendants’ need for discovery when it denied providers’ motions to quash and allowed
defendants discovery on a novel constitutional theory.
2. Providers’ assertion that lawful consent to disclosure is revoked by a
user’s reconfiguration of a communication from public to restricted
or by a user’s deletion of a public communication

As noted, providers concede that they may, pursuant to the lawful consent
exception set forth in 2702(b)(3), disclose a post configured by the user to be public.
They maintain, however, that the fact a user may have initially configured a post for
public distribution should not necessarily resolve the question of the applicability of the

Frontier Foundation, Facebook’s Eroding Privacy Policy: A Timeline (Apr. 28, 2010

[observing that in November 2009, Facebook reset user privacy default settings to

(May 22, 2014) <http://newsroom.fb.com/news/2014/05/making-it-easier-to-share-with-

communications at issue in this litigation were sent — Facebook again changed its
privacy policy default, reverting, for new users, from public to friends, and giving
existing users new tools to help ensure that they post publicly only when they intend to
do so]; regarding Instagram, see Instagram Help Center, Controlling Your
Visibility/Setting Your Photos and Videos to Private
<https://help.instagram.com/116024195217477> [as of May 22, 2018].
From what we can glean from the record, it appears that Renesha Lee may not
have changed the default on one of her Twitter accounts and made her tweets and/or any
replies private. (See ante, pt. I.D. and related discussion.) The record does not address
the configuration of Renesha Lee’s Facebook communications. Finally, regarding
Instagram, the record suggests that Renesha may have configured one Instagram account
to be private. In addition, the record suggests that she may have had, and deleted,
multiple additional accounts with some or all of the social media providers. The
configurations of these additional accounts are unknown. (See ante, fn. 5.) Regarding
victim Rice, the limited record suggests that he had accounts, perhaps multiple, and of
unknown configuration, with Facebook and Instagram — and that some if not all of those
accounts (including at least one relied upon by the prosecution’s gang expert) have been
closed. (Ibid.
51

lawful consent exception. Specifically, providers observe that a communication
originally configured to be public subsequently can be reconfigured by the user to be
restricted, can be deleted by the user, or the user can close the account.41 They argue that
when such a change occurs before a provider is served with a subpoena, the
reconfiguration or deletion should be understood as a revocation of lawful consent for
purposes of section 2702(b)(3) — with the result that the provider would be prohibited by
section 2702(a) from complying with a subpoena regarding any such communication.42
41
In this regard Facebook tells users: “If you accidentally share a post with the
wrong audience, you can always change it.” (Facebook, Privacy Basics/Manage Your
Privacy
<https://www.facebook.com/about/basics/manage-your-privacy/posts#6> [as of
May 22, 2018]; see also Facebook Help Center, How can I adjust my privacy settings?
<https://www.facebook.com/help/193677450678703?helpref=related> [as of May 22,
2018] [“You can view and adjust your privacy settings at any time”].) Twitter allows an
account to be changed from unprotected to protected and vice versa, and states: “If you
at one time had public Tweets (before protecting your Tweets), those Tweets will no
longer be public on Twitter, or appear in public Twitter search results [within the
provider’s system]. Instead, your Tweets will only be viewable and searchable on
Twitter by you and your followers.” (Twitter Help Center, About public and protected
Tweets/What happens when I change my Tweets from public to protected?

<https://support.twitter.com/articles/14016#> [as of May 22, 2018].) At the same time,
Twitter explains, the opposite also occurs: “If you later change your account settings to
no longer protect your Tweets, Tweets that were previously protected will become public
and may be indexed by third-party search engines.” (Twitter Help Center, Why are my
Tweets appearing on Google after deleting or protecting them?/Protected Tweets

<https://support.twitter.com/articles/15349#> [as of May 22, 2018].) Finally, Instagram
also allows an account to be changed from the default (public) to private, and vice versa.

2018].
42
Amicus curiae Google hypothesizes that any given communication originally
configured as public, or any subsequent reverse reconfiguration of a communication from
restricted to public, might conceivably be undertaken not by a registered user him- or
herself, but by a person or entity who uses or hacks the user’s account. Any such action,
Google argues, should be viewed as not constituting implied consent to disclosure by a
provider. We agree, and observe that the trial court on remand will be in a position to
permit providers to attempt to establish, as a preliminary matter, that a given
52

Defendants, by contrast, insist that once a registered social media user configures a
communication as public and posts it, triggering section 2702(b)(3)’s lawful consent
exception and presumptively allowing disclosure by a provider, the user cannot
subsequently revoke that implied consent to disclosure, even if the user promptly
reconfigures any post as restricted or deletes the post or closes the account. In support,
defendants assert that “any reasonable user knows once you make information publicly
available on social media it will be ‘. . . broadly and instantly disseminate[d]’ . . . ‘to a
wide range of users, customers, and services, including search engines, developers, and
publishers . . .’ just as Twitter advises in its terms of service.”43 Defendants assert that
after a public communication has been made so widely available, “[r]evoking consent is
as possible as un-ringing a bell.”
The parties have cited no decision explicitly addressing whether reconfiguration,
deletion or account closure operates to revoke consent for purposes of section 2702(b)(3),
nor have we found any such case. It appears that providers’ revocation claim poses a
question of first impression.
Providers may be understood to invoke Congress’s intent to protect users’ privacy
(as described ante, pt. II.A.), and to suggest that their proposed interpretation — under
which a provider would be required to honor a user’s reconfiguration or deletion so long
as it was undertaken by the time a subpoena is issued — would afford greater protection
to that privacy interest.44 Defendants, on the other hand, question whether a social media
communication was configured, reconfigured, or deleted, by someone other than the
registered account owner without authority of the owner.
43
See ante, footnote 34.
44
In support providers cite Van Patten v. Vertical Fitness Group, LLC (9th Cir.
2017) 847 F.3d 1037, 1047, which notes the “common law principle that consent is
revocable.” (Accord, Neder v. United States (1999) 527 U.S. 1, 21 [“ ‘ “[W]here
Congress uses terms that have accumulated settled meaning under . . . the common law, a
court must infer, unless the statute otherwise dictates, that Congress means to incorporate
53

user’s reconfiguration or deletion of a public post can in reality effectuate a revocation of
consent to disclosure45 — and whether Congress intended to ensure revocability of
consent in this context. Because the record does not indicate whether, in fact, any public

2014) 746 F.3d 1242, 1253 [quoting a dictionary for the proposition that “ ‘[u]nder the
common law understanding of consent, the basic premise of consent is that it is “given
voluntarily,” ’ ” and quoting the Rest.2d of Torts, § 892 for the proposition that
“ ‘Consent is a willingness in fact for conduct to occur’ ” and that “ ‘ “[C]onsent is
terminated when the actor knows or has reason to know that the other is no longer willing
for him to continue the particular conduct” ’ ”]; see also State v. Brown (Ore. 2010) 232
P.3d 962, 967 [“[A] person who places an item in plain view has relinquished any
constitutionally protected privacy interest in the item. That person, however, may renew
the privacy interest simply by removing the item from plain view.”].
45
In this regard, providers warn users, the acts of reconfiguration or deletion (or
even account closure) do not reach outside the provider’s system and prevent third parties
that may have indexed and cached any communication from continuing to make a given
communication available in its prior form to anyone on the internet. For example,
Facebook notes that in that situation it has no “control over content that has already been
indexed and cached in search engines” and it offers the same advice as do Instagram and
Twitter to their own registered users: in order to “request the immediate removal of [a
particular] search listing, you will have to contact the specific search engine’s support
team.” (Facebook Help Center, Appearing in Search Engine Results/I’m showing up in
the results of other search engines even though I’ve chosen not to

<https://www.facebook.com/help/392235220834308/?helpref=hc_fnav> [as of May 22,
2018].) And yet even if a user identifies each search engine that displays the
communication and seeks expedited recognition of any reconfiguration or deletion, the
providers indicate that the most that can be said is that any given search engine will
“eventually index updated . . . information” to reflect any reconfiguration protection or
post deletion. (Twitter Help Center, Why are my Tweets appearing on Google after
deleting or protecting them?/How and when to send Google a request to remove
information
<https://support.twitter.com/articles/15349#> [as of May 22, 2018].) Indeed,
Instagram observes that there is no such thing as immediate reconfiguration or deletion of
a public communication that has become available on a search engine; instead, “[i]t may
take some time for these [other third party search engine] sites and Google to re-index
and remove” a given communication “even if you delete your account.” (Instagram Help
Center, Controlling Your Visibility/Instagram Privacy on the Web/How can I remove my

54

communication sought by defendants was subsequently reconfigured or deleted before
the relevant underlying subpoena was issued, we express no opinion on the revocation of
consent issue — and leave it to be explored, if necessary, by the trial court on remand.
3. Technical difficulties that providers may face in determining the applicable
privacy configuration and retrieving deleted communications
and
protecting providers from excessive burdens

Providers assert that in light of a registered user’s ability to reconfigure
communications, “providers may not easily be able to determine the intended audience of
a communication at any given point in time” and “it may be difficult for a provider to
accurately identify” whether a given communication when posted was public or
restricted. Likewise, speaking on providers’ behalf, amicus curiae Google avers:
“Providers do not routinely maintain records of past privacy settings for each post or
message. Lacking such records, it would be impossible to determine the privacy
configuration that applied when a communication was posted or sent.” (Italics added.
Providers also assert that “if a user changes the privacy setting for a communication, a
service may not be able to accurately determine prior privacy settings.” In addition,
providers assert it would be difficult for them to retrieve deleted communications. As
noted by the trial court, however, a subpoena recipient has a general obligation to
undertake reasonable efforts to locate responsive materials. Again, any technical
difficulties a given provider may face in determining the relevant history of a particular
communication, or retrieving any deleted communication, are matters to be explored at
the anticipated hearing on remand.
Providers similarly urge that they should be protected from excessive burdens. As
observed ante, part II.A., Congress articulated its main purposes in enacting the SCA:
affording privacy protections to users while accommodating the legitimate needs of law
55

enforcement. It also articulated a tertiary goal: to avoid discouraging the use and
development of new technologies. Providers’ briefs characterize this additional purpose
as one of “enhanc[ing] the use of communications services and protect[ing] providers
from being embroiled as a nonparty in litigation.” Amicus curiae on providers’ behalf,
Google, characterizes this additional purpose even more specifically as “protecting
providers from an otherwise limitless burden of responding to requests to disclose their
users’ communications.” Providers rely on dictum in O’Grady, supra, 139 Cal.App.4th
1423, in which the court voiced concern about the prospect of such subpoenas to
providers in routine civil cases. (Id., at pp. 1445-1447.)46
In light of the statutory scheme, it appears that Congress sought to limit burdens
placed on service providers by various means — most obviously, by establishing broad
prohibitions and specific exceptions regarding access and disclosure under sections
2701and 2702, along with rules and procedures pursuant to which the government may
compel disclosure under section 2703. With regard to burdens related to disclosure in
particular, Congress significantly limited the potential onus on providers by establishing a
scheme under which a provider is effectively prohibited from complying with a subpoena
issued by a nongovernmental entity — except in specified circumstances. But when any
one of the exceptions does apply, there is no indication that Congress intended that
providers would be categorically relieved from the burden of compliance with an
46
In a related vein, providers observe that they stand in jeopardy of incurring civil
liability under section 2707 of the Act if they knowingly or intentionally violate the SCA.
But that section by its terms contemplates liability only for a provider that violates the
Act “with a knowing or intentional state of mind.” (Id., subd. (a).) Moreover, the statute
provides a safe harbor for a provider who, in “good faith,” relies on “a court . . . order.”
(Id., subd. (e)(1).
56

otherwise lawful civil or criminal subpoena. Hence, as the court held in Negro, supra,
230 Cal.App.4th 879, a provider may properly be subject to the burden of compliance
with a subpoena, even with respect to communications configured by the
registered user to be private, when a user expressly consents to disclosure by his or her
service provider. Likewise, a provider may properly be subject to the burden of
compliance with a subpoena when a user implicitly consents to disclosure by configuring
a social media communication as public.
Of course, any third party or entity — including a social media provider — may
defend against a criminal subpoena by establishing that, for example, the proponents can
obtain the same information by other means, or that the burden on the third party is not
justified under the circumstances. (City of Alhambra v. Superior Court (1988) 205
Cal.App.3d 1118, 1134; cf. Kling v. Superior Court (2010) 50 Cal.4th 1068, 1074-1075,
1078.) Indeed, the Act itself specifically contemplates that providers may raise such
issues in the context of compelled disclosure to a governmental entity under section
2703(d) (a court “may quash or modify such order, if the information or records
requested are unusually voluminous in nature or compliance with such order otherwise
would cause an undue burden on such provider”), and the same principles would apply in
the present setting.
As noted, providers advanced similar arguments regarding the burden of
compliance with the subpoenas in the earlier trial court proceeding. (Ante, part I.E.) In
response, the trial court ruled that absent additional factual information demonstrating
impossibility or the extent of burdens, it could not engage in any such balancing of
57

production versus burden. Providers’ current claim of undue burden can properly be
addressed by the trial court on remand.47
47
The trial court on remand might also consider two additional and somewhat
related legal issues that have been only generally alluded to in the briefing to date in this
case, but which are highlighted in our January 17, 2018 order granting review in the
related matter of Facebook, Inc., v. Superior Court (Touchstone) (2017) 15 Cal.App.5th
729 (S245203). That order directs the parties to address, among other things (1) whether
a trial court may compel a witness to consent to disclosure by a provider, subject to in
camera review and any appropriate protective or limiting conditions; and (2) whether a
trial court may compel the prosecution to issue a search warrant under the Act, on behalf
of a defendant.
Finally, yet another matter, not discussed in the parties’ briefs, may require
consideration on remand. As alluded to ante, part I.F., after the trial court confirmed its
production ruling, counsel for defendant Sullivan asked that providers be ordered to
preserve all data at issue in this case. The court stated that it would not immediately issue
an oral preservation order because it wanted the parties to first work out among
themselves language addressing the providers’ preservation obligations, and stated:
“You will have to draft something and submit it, and see if you can reach an agreement.
And if you get competing orders, we will have to have another hearing about that.” The
record before us, however, contains no preservation order; no mention of such an order
appears in the briefs; and the superior court docket for each case, as to which we have
taken judicial notice, reflects no such order. (See, e.g., Williams v. Russ (2008) 167
Cal.App.4th 1215, 1223 [addressing a party’s “failure to preserve evidence for another’s
use in pending or future litigation” and corresponding sanctions].
