C.A. No. 2022-0613-KSJM
Dear Counsel:
This letter resolves issues raised in the August 15, 2022 letter to the court from
Twitter, Inc. (“Plaintiff”), which this decision refers to as Plaintiff’s “Second Discovery
Motion.” The motion seeks relief in connection with discovery directed to Defendants
Elon R. Musk, X Holdings I, Inc., and X Holdings II, Inc. (“Defendants”) concerning
Defendants’ data science analysts (the “Data Scientists”). 1

Through this action, Plaintiff seeks to specifically enforce an Agreement and Plan
of Merger (the “Merger Agreement”) dated April 25, 2022, under which Defendants agreed
to acquire Plaintiff. 2 Section 6.4 of the Merger Agreement grants Defendants the right to
information from Plaintiff (subject to certain conditions, restrictions, and exceptions) “for
any reasonable business purpose related to the consummation of the transactions
contemplated by this [Merger] Agreement.” 3 In May 2022, Defendants demanded
information pursuant to Section 6.4 concerning Plaintiff’s methods of calculating
monetizable daily active usage or users (“mDAU”). 4 In response, Plaintiff provided its
“firehose” data—i.e., a live feed of data concerning public accounts on Plaintiff’s platform.
Defendants then provided Plaintiff’s firehose data to the Data Scientists, who conducted a
“preliminary analysis” of that data. 5 Based expressly in part on that preliminary analysis,
Defendants terminated the Merger Agreement on July 8, 2022. Plaintiff filed suit, and
Defendants responded with counterclaims that reference analyses performed by the Data
Scientists (with the preliminary analysis, the “Analyses”) at least eight times. 6

Defendants have advanced a variety of positions to shield from discovery the Data
Scientists’ information, including the Analyses. Although they abandoned most of those
positions, they maintain that the Data Scientists’ information is insulated from discovery
by the non-testifying expert protection and the work product doctrine. Through its Second
Discovery Motion, Plaintiff seeks a declaration that no blanket protection or privilege
applies to this information.

non-testifying experts in anticipation of litigation. 7 Rule 26(b)(4)(B) tracks the language

preliminary estimates show otherwise.”), 117 (“An analysis of Firehose data from the first
week of July, including processing visible accounts using a publicly-available machine-
learning spam detection model, shows that, during that timeframe, false or spam accounts
accounted for 33% of visible accounts.”), 118 (“[E]ven assuming that every single one of
the invisible accounts is a legitimate user, and not a false or spam account (an assumption
as conservative as mathematically possible), these preliminary findings indicate a floor for
the prevalence of false or spam accounts among Twitter’s mDAU of 10%, rendering
Twitter’s statements that less than 5% of mDAU is comprised of false or spam accounts
materially misleading.”) (emphasis in original), 119 (“[C]ontrary to the implication in the
2021 10-K that fewer than 10.85 million mDAU were false or spam accounts, preliminary
findings suggest that more than 20 million mDAU were false or spam accounts.”), 120
(“Not only does preliminary analysis reveal that Twitter’s false or spam accounts exceed
10% of mDAU, the Musk Parties estimate that false and spam accounts make up an even
more significant portion of the mDAU that actually see ads based on Twitter’s own data
regarding ad engagement among its userbase.”), 150 (“In reality, as discussed above,
preliminary estimates based on only the 30% of mDAU visible in the Twitter Firehose
already indicate that one third of visible accounts and 10% of the mDAU count may be
made up of false or spam accounts.”).

of its federal counterpart, and this court has looked to federal authorities when applying it. 8
The restriction stems from the concern that “[a]llowing routine discovery as to [non-
testifying experts] would . . . deter thorough preparation of the case and reward those whose
adversaries were most enterprising.” 9 The restriction prevents the “additional drawback”
that, after learning of experts that a party retained but elected not to have testify, “the
opponent might later seek to call them as witnesses to attest to views that the opponent
found congenial.” 10 The theory is that “[i]f the price for seeking expert consultation is
possibly to live or die by the unknown opinion of the expert first consulted, there will be
even more reluctance to consult.” 11
Rule 26(b)(4)(B) does not provide unqualified immunity. A party may obtain
discovery from a non-testifying expert “upon a showing of exceptional circumstances
under which it is impracticable for the party seeking discovery to obtain facts or opinions
on the same subject by other means.” 12 Rule 26(b)(3), which protects work product,

contains a similar exception and permits discovery of work product “only upon a showing
that the party seeking discovery has substantial need of the materials in the preparation of
the party’s case and that the party is unable without undue hardship to obtain the substantial
equivalent of the materials by other means.” 13 The exception for non-testifying experts in
Rule 26(b)(4)(B) has been described as “more exacting” than the exception for work
product in Rule 26(b)(3). 14
Rule 26(b)(4)(B) does not “shield testimony by a natural fact witness” from
discovery. 15 As the advisory note to the rule’s federal counterpart explains, the rule does
not protect “the expert whose information was not acquired in preparation for trial but
rather because he was an actor or viewer with respect to transactions or occurrences that
are part of the subject matter of the lawsuit. Such an expert should be treated as an ordinary

witness.” 16 When a party invokes Rule 26(b)(4)(B) to shield discovery of a fact witness,
this court is rightly skeptical. 17
In this case, Defendants insist that the Data Scientists were retained by counsel in
anticipation of litigation and to assist counsel in rendering legal services as non-testifying
experts. The language of the Data Scientists’ engagement letters provides support for this
assertion, as does the timing of their retention. 18
Yet, the Data Scientists were also “actor[s] or viewer[s] with respect to transactions
or occurrences that are part of the subject matter of [this] lawsuit.” 19 Defendants expressly
relied on the Data Scientists’ preliminary analysis to justify making additional information
requests and later terminating the Merger Agreement. 20 Defendants also rely on the
Analyses throughout their counterclaims. 21 In these circumstances, it is clear that the Data
Scientists did not act solely as non-testifying experts. Rather, at least with respect to the
Analyses, they are fact witnesses.

The Data Scientists’ dual-natured role forces the following question: To what degree
do the protections of Rule 26(b)(4)(B) extend to persons who played a dual role as fact
witnesses and non-testifying experts?
Plaintiff answers this question by citing Hexion, where this court declined to
recognize a party’s designation of a fact witness with knowledge about issues at the heart
of a case as a non-testifying expert. 22 There, the plaintiff-buyer terminated a merger
agreement with the defendant-seller, claiming that the seller had suffered a material adverse
effect and that the merger could not close because the buyer’s financing sources could not
be provided with a “satisfactory solvency opinion[.]” 23 The seller purported to retain its
financial advisor for the merger, Merrill Lynch, as a litigation consultant and attempted to
shield all of Merrill Lynch’s financial advice in connection with the merger from discovery
under Rule 26(b)(4)(B).
The Hexion court rejected the seller’s argument, holding that “Rule 26(b)(4)(B)
does not apply to Merrill Lynch in its role as [the seller’s] financial advisor because in that
role Merrill Lynch has acquired and continues to acquire information as an ‘actor’ in or
‘viewer’ of the [merger] transaction, which lies at the heart of this lawsuit.” 24 Furthermore,
because Merrill Lynch did not clearly distinguish between work it performed as a financial

advisor and as an ostensible litigation consultant, the court declined to recognize Merrill
Lynch as a non-testifying expert for any purpose whatsoever.
The logic of Hexion favors Plaintiff. Rule 26(b)(4)(B) does not protect the Analyses
that lie at the heart of this lawsuit. Because Rule 26(b)(4)(B) does not protect the Analyses,
it does not protect documents or communications relating to those Analyses. And if
Defendants failed to distinguish between the Data Scientists’ work performed for those
ends and any work performed in an expert capacity, Rule 26(b)(4)(B) does not protect any
of it.
Plaintiff argues for the same result under the “exceptional circumstances” standard.
As to the Analyses, Plaintiff has demonstrated “exceptional circumstances under which it
is impracticable for the party seeking discovery to obtain facts or opinions on the same
subject by other means.” 25 Defendants relied on the Analyses as a basis for termination
and in support of their counterclaims. To probe the veracity of Defendants’ assertions,
Plaintiff requires the Analyses. Plaintiff cannot obtain those facts through any other means.
Invoking case law interpreting the work product doctrine, Defendants argue that
“dual-purpose” documents generated by an alleged expert should be protected, even though
the materials also had a nonlitigation purpose, if the documents were prepared for
litigation. 26 Defendants urge the court to apply the “because of” test rather than following
25
Ct. Ch. R. 26(b)(4)(B).
26
See Defs.’ Response to Pl.’s Second Disc. Mot. at 24 (referring back to Defendants’
work-product argument); see also 8 Wright & Miller § 2024 at 512–14 (discussing the
dual-purposes scenario).

Hexion. Under the “because of” test, the court asks in light of “the totality of the
circumstances” why the document was prepared. 27 “If a document was generated ‘because
of litigation,’ then it is likely privileged,” but “[i]f the document was created for some other
reason, such as a business purpose, then it is likely not protected.” 28
Defendants cite to cases declining to compel the production of documents under the
“because of” dual-purpose test. 29 Each of the dual-purpose cases on which Defendants rely
analyzes the dual-purpose issue with some reference to the substantial-need standard of
Rule 26(b)(3). 30 As discussed above, the substantial-need standard is less exacting and

easier to meet than the exceptional-circumstances standard. It follows that if a court denied
protection under the lower standard, then the court also should deny protection under the
higher standard.
Defendants’ reliance on Rohm & Haas illustrates why their reliance on the because-
of case law is misplaced. The discovery dispute there concerned a dynamic financial model
that the defendant used for corporation decision-making. The plaintiff argued that the
model was critical to its ability to understand the defendant’s representations to banks,
rating agencies, and its board. The defendant produced multiple versions of the model but
claimed that a recently updated version was protected work product because it was created
at the request of the defendant’s head of litigation for “litigation support and settlement
analysis.” 31 The court agreed with the defendant, observing that it was “hard pressed to
think of any information that warrants greater protection under attorney work product
doctrine than potential settlement strategies prepared at the direction of counsel.” 32
Applying the because-of test, the court observed that “the litigation purpose of the [model]
sufficiently permeates the business purpose of the model to warrant work product
protection.” 33 The court then factored that holding into the governing substantial-need
standard and concluded that the plaintiff failed to meet its burden.

Defendants parrot the “permeates the business purpose” quote of Rohm & Haas in
support of their position, claiming here that the litigation purpose of the Data Scientists’
Analyses sufficiently permeates their business purpose as to render them immune from
discovery. The court accepts Defendants’ representation to this effect. Even so, that is not
sufficient to shield the Analyses from discovery. Unlike in Rohm, Plaintiff would win
under a work product analysis because it can demonstrate substantial need for the Analyses.
The plaintiff in Rohm & Haas could not demonstrate substantial need because the plaintiff
already had access to multiple versions of the model at issue, and the model did not form
the basis for any allegations at the heart of the case. Here, Plaintiff does not have access
to any versions of the Analyses, which are central to various aspects of this case.
Plaintiff’s ability to demonstrate substantial need for the Analyses renders
Defendants’ because-of cases inapposite on the application of Rule 26(b)(4)(B). Plaintiff
has shown the exceptional circumstances necessary to warrant production of Analyses,
even if they would otherwise be protected under Rule 26(b)(4)(B).
Work Product Protection
In addition to using work product cases to bolster their invocation of the protection
for non-testifying experts, Defendants invoke the work product doctrine independently. To
that end, they contend that any otherwise-discoverable material in the Data Scientists’
possession was generated at least in part “in anticipation of litigation” and is thus shielded
by Rule 26(b)(3).
C.A. No. 2022-0613-KSJM
August 25, 2022
Page 12 of 14
Rule 26(b)(3) generally protects “documents, electronically stored information, and
tangible things” that have been “prepared in anticipation of litigation or for trial by or for
another party or by or for that other party’s representative (including the other party’s
attorney, consultant, surety, indemnitor, insurer, or agent).” 34
Rule 26(b)(3) does not provide an unqualified protection. As discussed above, the
rule permits discovery of work product “upon a showing that the party seeking discovery
has substantial need of the materials in the preparation of the party’s case and that the party
is unable without undue hardship to obtain the substantial equivalent of the materials by
other means.” 35 This decision has already explained that Plaintiff meets the substantial-
need test as to the Analyses.
Equally important, Rule 26(b)(3) only protects the work product of the attorney.
“At its core, the work-product doctrine shelters the mental processes of the attorney.” 36
The doctrine does not shelter the mental processes of the expert, which are subject to a
separate legal analysis and framework discussed above. 37 A non-testifying expert’s

See 8A Wright & Miller § 2029 at 17–18 (explaining that “[t]he knowledge of an expert

26(b)(4)(B) advisory committee’s note (1970) (noting that the provisions of subdivision
(b)(4) “repudiate the few decisions that have held an expert’s information privileged simply
because of his status as an expert” and “reject as ill-considered the decisions which have
sought to bring expert information within the work-product doctrine”).

information “is not itself work product.” 38 Thus, to the extent Defendants object to
production of all the Data Scientists’ documents on the grounds that they categorically
constitute protected work product, that objection is overruled.
That said, “as a collaborator in the development of pretrial strategy, a non-testifying
expert may become a unique repository of insights into counsel’s opinion work
product[.]” 39 And while Plaintiff has demonstrated exceptional circumstances and thus a
substantial need for the Analyses, it is possible that communications with counsel
concerning the Analyses reflect work product. It is difficult to assess that possibility at this
stage because the documents at issue have not been logged. In any event, to the extent that
Plaintiff seeks a declaration that Defendants may not assert work product protection over
any of the Data Scientists’ documents, that request is denied.
Conclusion
Summing it up, to the extent that Defendants have lodged a blanket objection to
producing all of the Data Scientists’ documents as non-testimony expert materials or work
product, that objection is overruled. At a minimum, Defendants must produce the
Analyses.
That leaves documents and communications and drafts concerning the Analyses.
Rule 26(b)(4)(B) does not apply to those materials. To the extent Defendants claim that
any document contains work product, Defendants must identify that document on a

privilege log. At that point, Plaintiff can seek production of specific documents. 40
Plaintiff’s Second Discovery Motion is therefore granted in part.
This decision also has not reached the thorny question of whether Defendants may
assert privilege over the Data Scientists’ documents and communications that post-date the
Analyses. To be clear, this decision neither endorses nor rejects any arguments concerning
that discovery. Given the dual role of the Data Scientists, however, Defendants should log
any such communications withheld on privilege grounds.
IT IS SO ORDERED.
