that the plaintiff considered their contract to be breached
and was “likely going to do something about it” triggered the
defendant’s preservation obligations)).
Text messages from a plaintiff to a defendant threatening a
lawsuit two years before litigation started, even where the
plaintiff subsequently apologized for the text messages and
appeared friendly, but did not expressly retract the threat
(Clear-View Tech., Inc. v. Rasnick, 2015 WL 2251005, at *2, *7
(N.D. Cal. May 13, 2015)).
On the other hand, courts have held that written demand letters
that do not adequately warn of litigation might be insufficient to
trigger the duty to preserve (see, for example, Cache La Poudre
Feeds, LLC v. Land O’Lakes, Inc., 244 F.R.D. 614, 623 (D. Colo.
2007) (finding a plaintiff’s demand letters that described the
defendant’s potential trademark infringement were insufficient
to trigger the defendant’s duty to preserve because the letters
did not threaten litigation outright and even suggested the
possibility of a non-litigious resolution); Ind. Mills & Mfg., Inc.
v. Dorel Indus., Inc., 2006 WL 1749410, at *4 (S.D. Ind. Feb. 16,
2006) (similar); but see Goodman v. Praxair Servs., Inc., 632 F.
Supp. 2d 494, 510-11 (D. Md. 2009) (distinguishing Cache and
holding the defendant’s duty to preserve relevant evidence
began when the defendant received the plaintiff’s letter stating
that the plaintiff had consulted two attorneys and, if forced
to litigate, the plaintiff could receive damages in excess of the
disputed contract amount)).
Sending preservation demand letters to an adversary
requesting that certain evidence be preserved before bringing
formal claims has become an increasingly popular practice in
recent years. These demand letters are likely to trigger a party’s
duty to preserve once the party receives the letter (see Stedeford,
2016 WL 3462132, at *9-10). However, where a request to
preserve evidence does not sufficiently warn the receiving
party of potential litigation and does not clearly indicate that
the evidence described in the letter might be relevant to
potential litigation, some courts have found that the notice
was insufficient to trigger the recipient’s duty to preserve (see,
for example, McIntosh, 2016 WL 1274585, at *33 (finding there
was no duty to preserve where the “tone, informality, and other
characteristics” of a letter might not have forecasted litigation to
a reasonable observer, and the letter did not clearly convey that
videotape evidence might be relevant to future litigation)).
DETERMINING THE SCOPE OF PRESERVATION
BEFORE LITIGATION
A potential litigant is not expected or required to “preserve
every shred of paper, every e-mail or electronic document, [or]
every backup tape.” Instead, parties that reasonably anticipate
litigation should preserve “unique, relevant evidence that
might be useful to an adversary” or “is reasonably likely to be
requested during discovery.” (Zubulake, 220 F.R.D. at 217; see
also Marten Transp. Ltd., 2016 WL 492743, at *5, *10 (denying
the defendant’s motion for sanctions under FRCP 37(e) in
part because the lost ESI was outside the scope of the duty to
preserve).) In the context of FRCP 37(e), this analysis requires a
potential litigant to assess:
Which individuals are potential custodians of ESI that must
be retained.
The categories of ESI that the party must preserve.
Noting the expense that preservation can impose on parties,
the 2015 advisory committee note to FRCP 37(e) suggests that
proportionality might be relevant to a party’s determination
of the scope of preservation (see 2015 Advisory Committee’s
Note to FRCP 37(e)). Although no court has yet addressed
this issue, the recently proposed Third Edition of the Sedona
Principles expressly direct parties to consider proportionality
when determining preservation scope (The Sedona Principles,
Third Edition: Best Practices, Recommendations & Principles for
Addressing Electronic Document Production, Principle 5 & cmt.
5.a. (Mar. 2017) (Public Comment Version)).
IDENTIFYING CUSTODIANS OF ESI
The “duty to preserve extends to those employees likely to
have relevant information – the ‘key players’ in the case”
(Zubulake, 220 F.R.D. at 218). Identifying these key players is
a fact-specific inquiry that might require counsel to interview
potential custodians to determine who might have discoverable
information about potential claims.
Counsel should keep in mind that potential custodians are not
limited to a party’s employees and officers. A party’s duty to
preserve can also extend to ESI it owns or controls but is in the
possession of a third party (see GenOn Mid-Atl., LLC v. Stone &
Webster, Inc., 282 F.R.D. 346, 353-56 (S.D.N.Y. 2012); In re NTL,
Inc. Sec. Litig., 244 F.R.D. 179, 195-97 (S.D.N.Y. 2007) (finding
the defendant had a duty to preserve documents and ESI even
though the majority of these materials were in a non-party’s
possession), aff’d sub nom., Gordon Partners v. Blumenthal, 2007
WL 1518632 (S.D.N.Y. May 17, 2007)).
Search Possession, Custody, and Control of ESI for information on the
applicable federal rules on the possession, custody, and control of ESI,
the traditional tests courts use to determine control over documents
that non-parties possess, and emerging jurisdictional issues about
cloud-based ESI.
Identifying the appropriate custodians and third parties
with relevant information is a dynamic process. As litigation
proceeds, or if pleadings are amended, counsel might need
to identify and consult with other custodians of ESI that might
become relevant as discovery reveals new facts or as claims or
allegations are added or modified in a case.
IDENTIFYING WHAT ESI MUST BE RETAINED
A party must take reasonable steps to preserve all relevant ESI
under FRCP 37(e), including emails, shared files, social media,
and data sources (Marten Transp., Ltd., 2016 WL 492743, at *5;
see also, for example, Congregation Rabbinical Coll. of Tartikov,
Inc. v. Vill. of Pomona, 138 F. Supp. 3d 352, 387-88 (S.D.N.Y.
2015) (holding the duty to preserve applied to social media
posts and text messages)). The preservation duty includes an
obligation to identify, locate, and maintain “information that
