.The plaintiff contends that the principal of a n activist hedge fund breached his

fiduciary duties by engaging in insider trading. The plaintiff has moved for sanctions based on the defendants ’ failure to preserve electronically stored information (“ESI”). T he plaintiff served document requests that asked for t he hedge fund principal’s texts. The defendants did not produce any texts and averred that texting was contrary to the fund’s business policies. When other parties produced texts with the hedge fund principal, the plaintiff pressed the issue. After conclud ing that the hedge fund and its principal had spoliated evidence, the plaintiff filed a motion for sanctions for failing to preserve ESI. The hedge fund principal received three litigation hold notices that instructed him to take affirmative steps to pres erve texts on his personal devices . The hedge fund principal did nothing. He now posits that his texts were lost in October 2021, when he upgraded to a new iPhone

. Even the defendants admit his explanation makes no sense, because Apple backs up iMessages a nd other data to the cloud. The hedge fund principal has not suggested that other data was lost, such as pictures, applications, or contacts. Rather than remembering a devastating loss of all his data, he barely recalls the event. The iPhone upgrade thus n ot only uncharacteristically resulted in a loss of data, but strangely resulted only in the loss of texts. The plaintiff then asked for texts from other key hedge fund personnel. Eight months later, the hedge fund responded that its general counsel ha d no texts and couldn’t explain why. He now posits that his texts disappeared in early October 202 0

. He recalls that he was personally cleaning his swimming pool when he accidentally2

dropped his phone into the water. He sent the phone to be repaired, and he thinks the repair must have caused his texts to be lost. Like the hedge fund principal, t he general counsel does not recall a painful disappearance of all his data, including treasured pictures , his applications , and contacts. He only dredged an insignifi cant event from memory after finding a receipt for the repair. For purposes of this litigation, the disappearance of the hedge fund principal’s
texts proved serendipitous. The plaintiff had just served a comprehensive document request

. Weeks later, the de fendants moved to stay discovery , where they argued carefully that a stay would not prejudice the plaintiff because no then

- existing evidence would be lost. The court denied the stay. The hedge fund’s head trader also has no texts

. But in lieu of a third suspiciously flukey data loss, he admits setting his iPhone to delete texts after thirty days . Even after receiving a li tigation hold, h e never changed that setting. Court of Chancery Rule 37(e) governs when a requesting party can obtain sanctions for a responding party’s failure to preserve ESI. To obtain sanctions, the requesting party must show (i) the responding party had a duty to preserve the ESI, (ii) the ESI is lost, (iii) the l oss is attributable to the responding party’s failure to take reasonable steps to preserve the ESI, and (iv) the requesting party suffered prejudice. To obtain a presumption or a default judgment, the requesting party must show that the responding party ac ted recklessly or with the intention of preventing another party from using the evidence in litigation.3

The plaintiff made each showing. The hedge fund and its principal had a duty to preserve ESI . That duty arose at least as early as February 2018 , when the hedge fund principal received the first litigation hold notice . The hedge fund and its principal failed to take reasonable steps to preserve texts, most notably by not imaging any personal devices. The texts were lost due to that failure

. The plaintiff suffered twofold prejudice from the loss

. The plaintiff cannot use the evidence to prove its affirmative case. The plaintiff also cannot use the evidence
to cross

- examine the hedge fund principal and other defense witnesses when they attempt to prove thei r defenses. To remedy the first category of prejudice, the court will presume at trial that the hedge fund traded on the basis of a non - public approach from an acquiror. The court also will presume that the hedge fund ’s trading caused the sale process to fall outside a range of reasonableness. To remedy the second category of evidence, t he court will require the defendants to meet a burden of proof that is increased by one level. Rather than rebutting the presumptions or proving issues by a preponderance of the evidence, the defendants will have to adduce clear and convincing evidence. The plaintiff also has been prejudiced by having to spend time and resources

on this issue. T he defendants must pay all of the fees and expenses that the plaintiff incurred

. That includes not only the motion itself, but also the time required to pin down the defendants on their positions and to confirm that the ESI was not available from other sources.4 I. FACTUAL BACKGROUND The fact s are drawn from the parties’ submissions in connection with the motion seeking sanctions for spoliation

. 1 The court has also considered other documents of record. A. Denner, Bioverativ , and Sanofi D efendant Alexander J. Denner is the founder and controlling principal of Sarissa Capital, an activist hedge fund

. Four of his affiliates are defendants (collectively, “Sarissa”). In 2017, Denner was a director of Bioverativ, Inc., a publicly traded biotechnology company . In May, Sanofi S.A. approached Denner and an other director, Brian S. Posner . Sanofi expressed interest in acquiring Bioverativ for $90 per share. Bioverativ ’s common stock closed that day at $54.86 per share , so the propos al represented a 64% premium to market

. Denner and Posner told Sanofi that th e time was not right for an acquisition

. The discovery record to date indicates that Posner reported Sanofi’s interest to Bioverativ’s other directors, but did not mention the price. There are no contemporaneous documents evidencing board consideration or acknowledgement of the offer, and there was no board vote on a response. All of the Bioverativ directors testified that they knew about Sanofi’s approach. Except for Posner and Denner, none

recalled knowing the price. A contemporaneous email from Posner to outside counsel references the Sanofi approach without mentioning the price. DX 14. B. Sarissa Buys Stock. J ust days after Denner’s meeting with Sanofi , Sarissa ’s head trader began purchasing Bioverativ stock.

• On May 24, 2017, Sarissa purchased 340,000 shares.

• On May 25, 2017, Sarissa purchased 130,000 shares.

• On May 26, 2017, Sarissa purchased 450,000 shares.

• On May 30, 2017, Sarissa purchased 90,000 shares. There is no contemporaneous evidence of any prior plan to rapidly acquire su ch a large position. The only written communication relating to the trades is an email in which Denner tells the head trader to “Keep going

. ” PX 3. Before those purchases, Sarissa only owned 155,000 shares. Within a week after Denner’s meeting with Sanofi , Sarissa had purchase d 1,010,000 shares for $56.3 million . Bioverativ stock went from 3.3% of Sarissa’s p ortfolio to 27.7%. Before Sarissa’s first purchase, its general counsel (Mark DiPaolo) emailed Bioverativ’s general counsel (Andrea DiFabio) to ask if she wa s aware of any material

non - public information that c ould limit Sarissa’s ability to trade. DiPaolo did not mention Sanofi’s $90 per share offer, and DiFabio testified that she did not know about it. She therefore told DiPaolo that she did not know of anything. Posner was the only other Bioverativ director who knew about the price. He bought 2,000 shares for approximately $53.80 per share , representing a total6

investment of $107,600. No one has suggested that the other Bioverativ directors suddenly purchase d shares. C. Denner Str ings Sanofi Along
. Sarissa stood to make massive profits if Sanofi acquired Bioverativ , but Section 16(b) of the Securities Exchange Act of 1934 loomed as an impediment. That statute requires that an insider disgorge short

- swing profits from any sale that takes place less than six months after the purchase. Denner’s solution was to delay an y engagement with Sanofi so that the sale would take place after the short

- swing period closed. When Sanofi re approached in June 2017 and again in September 2017, Denner responded that Bioverativ was not for sale. The discovery record indicates that he di d not report those contacts to the b oard. See PX 11. D. Bioverativ Agrees To A Sale. By October 2017, the short

- swing period was about to expire. This time , when Sanofi came calling, Denner proposed a single

- bidder process. The board knew nothing about th at i nquiry. S everal weeks later, in late November 2017, Sanofi offered to acquire Bioverativ for $98.50 per share. Bioverativ’s management team and its financial advisors valued the company at more than $150 per share . After receiving Sanofi’s offer, the dire ctors asked for a higher bid, and Sanofi increased its offer to $101.50. At that point, the directors countered at $105 per share, almost one

- third below the standalone valuation. Sanofi accepted.7

Denner led the negotiations for Bioverativ . Stephen Sands, a Lazard banke r , led the negotiations for Sanofi. Denner and Sands had known each other professionally for over a decade. The d iscovery record reveals that they texted during the negotiations. None of those texts exist. E. The Bioverativ Hold On Janua ry 21, 2018, the companies announced the t ransaction . On February 8, 2018, Bioverativ filed its proxy statement. Stockholders filed putative class actions challenging the sufficiency of the proxy statement. On February 21, 2018, Bioverativ’s general counsel circulated a litigation hold. P X 12 (the “ Bioverativ Hold”). Denner received it. T he Bioverativ Hold informed i ts recipients that “ Bioverativ and its employees are under an obligation to hold on to any and all information and documents (including electronically

- stored information, such as emails) within their possession, custody or control that may relate to Biover ativ’s acquisition by Sanofi.” Id. The Bioverativ Hold instructed recipients to take affirmative steps to preserve documents. Under a heading titled, “What do I need to do?” it stated: You must take affirmative steps to prevent any alteration, deletion, de struction, or mo di fication of any information or documents you possess now or in the future that could be related to the hold To be clear, this legal hold applies to documents and information within Bioverativ’s possession , custody or control or your indiv idual or future possession, custody or control. Id. The Bioverativ Hold expressly extended to texts. Under a heading titled, “Other than email, what items do I need to hold on to?” the notice stated:8

Please review the list below. You must hold on to any in formation, documents and data stored in or on any medium

— paper, electronic, or other

— that may be relevant to Bioverativ’s acquisition by Sanofi even if you keep it on your mobile device or on your home computer. This includes but is not limited to:

. . .

• SMS or text messages;

. . .

• Documents and information stored in a cloud environment. To be clear, any and all documents, data and information that may relate to Bioverativ’s acquisition by Sanofi should be preserved regardless of whether they are favora ble or unfavorable to Bioverativ, or whether they appear unimportant or trivial. Id. The Bioverativ Hold extended explicitly to “ personally

- owned computers or devices (including cell phones, tablets, etc.).” Id. The re is no evidence Denner took any action in response to the Bioverativ Hold. There is no evidence that Sarissa took any action either. If they had, the lost texts would have been preserved. F. The Sanofi Hold On March 15, 2018, Sanofi issued a litigation hold. PX 13 (the “Sanofi Hol d”). Denner received it. The Sanofi Hold specifically called out texts on smart phones. Under the heading “ YOU MUST PRESERVE BOTH DOCUMENTS AND ELECTRONICALLY STORED INFORMATION ,” it stated: You must retain paper documents and ESI regardless of location or media format. For example, you must retain relevant ESI on computers and external storage devices such as cell phones, smartphones, iPads, tablets, and removable media such as USB drives.

. . . Examples of ESI:

. . . text messages

. . . on any personal de vices. Id.9

The Sanofi Hold specifically identified the need to take affirmative steps to preserve ESI. Under a heading titled, “ DO NOT DELETE RELEVANT INFORMATION , ” the Sanofi Hold stated: Do not delete e

- mail or ESI that relates to this matter

. . . If you are aware of any other documents or information that may relate to this Matter that are stored in any other format or location where they are likely to be modified or deleted (either due to automatic or manual processes), you must take affirmative actions to preserve these documents and information. Id. There is no evidence that Denner took any action in response to Sanofi Hold. There is no evidence that Sarissa took any action either. If they had, the lost texts would have been pre served. G. The S arissa Hold On September 4, 2019, the Securi ti es and Exchange Commission (“SEC”) served subpoenas on Denner and Sarissa seeking “All Documents Concerning [Biover a tiv] or trading in the securities of [Biover a tiv ],” “All Communications with Sanofi,” and “All Communications with Denner Concerning Sanofi, [Biover a tiv], or trading in the securities of [Biover a tiv].” Dkt. 212, Ex . A at Request Nos. 3

– 5 & Ex. B at Request Nos

. 3, 5. On September 5, 2019, Sarissa’s gene ral counsel (DiPaolo) circulated a litigation hold to “All staff.” PX 15 (the “Sarissa Hold”). The Sarissa Hold instructed all staff to “preserve any and all documents and/or communications with, concerning, relating to, or in any way discussing or mentio ning Biov e rativ, Inc. or Sanofi S.A.” Id. It continued: “ Until otherwise notified, do not discard, delete, alter or destroy any such materials in your possession or10

under your control even if such documents would otherwise be routinely discarded or destroy ed in the ordinary course of your business
. ” Id. The Sarissa Hold expressly encompassed texts on personal devices: You must preserve all potentially responsive documents now in existence or that may be created in the future, whether in hard

- copy form or s tored electronically, including electronic documents stored on or in any form of media, including, but not limited to, the following: mobile devices, whether firm issued or personal (including iPhones, Androids, and Blackberries),

. . . iPads, tablet devic es, PDAs,

. . . and information available in the “cloud” or on social media websites.

. . . All destruction or recycling programs, protocols and routines that would otherwise apply to the documents being preserved must be suspended immediately. Id. ; accord id. (defining “document” to include “ text messages ”). After circulating the Sarissa Hold, DiPaolo consulted with outside counsel about how to implement it. 2 Outside counsel asked DiPaolo about texts. DiPaolo responded that he did not text for busi ness and that he did not believe Denner did either , but he would verify that. DiPaolo and outside counsel decided they would not collect text messages at that time, but outside counsel asked that Sarissa’s users preserve text messages and check with counse l before buying a new phone and transferring data to a new device

. DiPaolo avers that he personally went through Denner’s phone looking for text messages relating to “Sarissa’s purchases of Bioverativ securities .” DiPaolo Aff. ¶ 6. The scope of the SEC sub poenas was much broader: They sought “All

2 Sarissa produced notes from two meetings subject to a Rule 510(f) order. Neither the production of the evidence nor this decision’s reference to it waives any privilege that otherwise might attach to the documents.11

Communications with Denner Concerning Sanofi, [Bioverativ], or trading in the securities of [Bioverativ].” Dkt. 212, Ex A at Request No. 4

. DiPaolo claims he did not find any responsive texts. In this action, other parties have produced texts from Denner relating to Bioverativ . There are also emails referring to texts from Denner relating to Bioverativ

. DiPaolo either applied his narrow definition to exclude them , missed them inadvertently, or consciously ignored them. The latter is a concern, because to the extent that Denner texted about Sarissa’s trading, he likely texted with DiPaolo . Allowing DiPaolo to review Denner’s
texts meant DiPaolo was looking for texts that could i mplicate himself. At a follow

- up meeting with outside counsel , DiPaolo reported that Sarissa’s policies prohibited the use of text for business purposes. He reiterated that he had no recollection of texting himself. He said that he had reviewed Denner’s t exts and found nothing

. Based on DiPaolo’s representations , outside counsel agreed to “table any collection of mobile data/text messages at this time but asked [Denner] to preserve this data.” Outside counsel also asked Denner to contact counsel “ for guidance should he want to buy a new device or discard the current device.” T here is no evidence that any steps were taken to preserve Denner’s data. There is no evidence that Denner contacted anyone for guidance before replacing his phone. Because the Sa rissa Hold went to all staff, it inferably went to Pat Garofalo , Sarissa’s head trader . He had his phone set to delete texts after thirty days . He did12

not turn off that setting after receiving the Sarissa Hold . He did nothing to preserve his texts. DiPaol o sent the Sarissa Hold, so he necessarily knew about it. He did nothing to preserve his texts either

. The three custodians for the SEC collection ended up being Denner, DiPaolo, and Denner’s former personal assistant, who had left Sarissa in September 2018. No

one collect ed her cell phone before she left. The SEC collection thus did not involve
any collection of texts, nor any imaging of phones to preserve ESI

. DiPaolo conducted the only sear ch for texts by reviewing Denner’s phone. That was a manual self

collection by an inferably interested party. H. The Pool Incident After the SEC collection, the DiPaolo was personally cleaning his swimming pool when he accidentally dropped his phone into the water. He has a receipt showing he had the phone repaired on September 28, 2020. DiPaolo believes that he lost his texts when the phone was repaired. Strangely, the repair seems to have affected his texts and nothing else. DiPaolo has not suggested that he lost other data, such as pictures, applications, or contacts. Rather than recalling a traumatic event involving the disappearance of treasured photos and the hassle of rebuilding his contacts and restoring other information, DiPaolo barely remembers the incident. Only the repair receipt jogged his memory. Nor do the dates work. DiPaolo believes he lost his texts as a result of the repair, yet the missing texts are not tied to September 28, 2020. He has no texts from13

before October 9, 2020. It would be s trange for a repair to cause the loss of texts sent during the twelve days after the repair took place. I. This Lawsuit On December 15, 2020, the plaintiff filed this lawsuit. Based on Sarissa’s stock purchases, the plaintiff asserts a claim against Denner fo r breach of fiduciary duty , plus a claim against Sarissa for aiding and abetting Denner’s breaches. In substance, the plaintiff assert s that Denner and Sarissa engaged in insider trading

. The plaintiffs also asserted claims against other defendants that ha ve been settled. Denner and Sarissa moved to dismiss the claims against them under Rule 12(b)(6). After complet ing briefing, the plaintiff served document requests on September 27, 2021 . Dkt. 44. The defendants responded by moving to stay discovery. They relied on a line of Court of Chancery decisions that freely grant stays of discovery pending resolution of motions to dismiss

. See Dkt. 47. Those rulings presume that a stay will not prejudice the plaintiff because the defendants will preserve potentially relevant evidence. Citing those precedents, the defendants argued that the plaintiff would not suffer prejudice in this case due to the absence of “any serious risk of currently

- available information becoming unavailable while the Court conside rs the pending Motions to Dismiss.” Id. ¶ 17. In reply, the defendants reiterated that the plaintiff did not face any risk of prejudice from his “professed concerns” about failures to preserve evidence. Dkt. 52 ¶ 17. Although not conspicuous at the time, t he defendants’ reference to “currently

- available information becoming unavailable” now seems carefully worded.14

On November 18, 2021, the court issued an order that denied the defendants’ motion for a stay, explaining: As the plaintiffs ’ authorities recount , defendants are not entitled to an automatic stay of discovery pending disposition of a pleading

- stage motion. There must be good reason to grant the stay. Here, the court has reviewed the pleading

- stage record, and it appears highly unlikely that the mot ion to dismiss will be granted, much less dispose of the case in its entirety. It is perhaps possible that a limited aspect of the complaint might be dismissed, but the probability is sufficiently low that discovery should not be stayed pending the outcome of the defendants’ pleading

stage motion

. Dkt. 5 5

. J. The Defendants Belatedly Take Steps To Identify And Preserve Evidence
. It was only after the court’s order that defense counsel began thinking about what sources of evidence would be responsive and shoul d be identified, preserved, collected, reviewed, and potentially produced. That was too late. The plaintiff filed the case in December 2020. Defense counsel should have started taking steps to identify and preserve information by at least then. Defense counsel acted too late in another sense as well. To repeat, the plaintiff served document requests in September 2021. Soon after , f or reasons that no one has been able to explain, Denner lost all of his texts from before an as - yet unidentified date in October 2021. Denner recalls upgrading his iPhone to a new model, and he thinks the upgrade caused the loss. That would be bizarre, because Apple facilitates upgrades by transferring data to the new iPhone from the cloud. No one on the defendants’ side has been able to explain why Denner’s iPhone upgrade c ould have caused the loss of his texts.15

There is no evidence that Denner consulted with anyone before replacing his iPhone

. T he litigation holds told him to do that. Outside counsel asked him to do th at

. Like DiPaolo, Denner has not suggested that he lost other data, such as pictures, applications, or contacts. Denner also does not vividly recall discovering that he had lost cherished photos , nor does he rue the burden s of restoring his data from other sources. He barely re members it

. Like DiPaolo’s pool mishap, the atypical iPhone upgrade seems to have affected his texts and nothing else. K. The Defendants Fail To Produce Any Texts. As noted, defense counsel only began to consider their preservation and collection responsibilities after the court denied the defendants’ motion to stay discovery

. For their baseline document collection, defense counsel decided to use the documents gathered in response to the SEC subpoenas in September 2019. Defense

coun sel did not take any affirmative steps to identify custodians or sources. In January 2022, defense counsel proposed to the plaintiff that Denner be the only custodian. The plaintiff initially did not ask for more custodians. The plaintiff did ask for conf

irmation that the production would include Denner’s personal email, Sarissa email, other business email, instant message, mobile devices, laptops and desktops, cloud storage, and shared network drives. At that point, defense counsel compared those data sou rces with w hat had been gathered for the SEC collection a nd identified additional data that needed to be secured , including potential ly text messages, nonbusiness email addresses, cloud

- based data, and paper documents

. Once again, defense counsel did not a ct independently or take initiative . They did not16

fulfill their own responsibilit ies to identify data sources; they merely considered what the plaintiff identified. To learn about texts, defense counsel consulted with Sarissa’s general counsel ( DiPaolo )

. He repeated his mantra that Sarissa had a policy against using text messages for business purpose and that he did not believe that Denner had any responsive text messages. Rather than imaging Denner’s phone or reviewing his text messages themselves, defens e counsel asked Denner’s assistan t to search his text s . The plaintiff had requested documents from Denner for months in 2016 that were outside the scope of the SEC collection . In February 2022, defense counsel collected additional documents from Denner’s e mail account. Later that month, the plaintiff and defense counsel agreed on a search protocol for Denner’s emails, and the plaintiff agreed that Sarissa did not need to run searches on any other Sarissa personnel. Defense counsel ran the agreed

- upon search terms and reviewed the hits for responsiveness, then produced those documents on a rolling basis. In March 2022, Denner’s assistant reported to defense counsel that no text messages from 2017 to 2018 existed on Denner’s phone an d that the earliest text messages were from October 2021. Denner’s assistant also said that Denner did not have any messages available in iCloud. Defense counsel asked for the first time about Denner’s iPad and was told no text messages from 2017 to 2018 e xisted there either. No one told the plaintiff. In June 2022, the court issued a decision that largely denied Denner and Sarissa’s motion

. Goldstein v. Denner , 2022 WL 1797224 (Del. Ch. June 2, 2022). That17

decision found it “reasonable to infer that Denne r bought the shares with the expectation that Sarissa would profit from a near

- term sale of [ Bioverativ ] ” and “reasonably conceivable that the conduct giving rise to the Insider Trading Claims tain t ed the sale process. ” Id. at *9, * 12. The decision noted t hat discovery would play an important role in supporting or refuting those inference s and that on a developed record, the court might reject or question whether the defendants had traded based on inside i n format i on. For example, discovery might show that D enner “ would have increased Sarissa’s equity position after the Spinoff in any event.” Id. at *9 n. 5

. L. The Plaintiff Questions The Lack Of Texts. Although Denner and Sarissa’s production did not contain any texts , other partie s produced texts from Denner. Two directors produced forty

- five texts, including texts sent during board meetings in which Denner complained about management’s opposition to the Sanofi t ransaction. See PX 1. On June 14, 2022, the plaintiff informed defense counsel that Denner appeared to have texted for business purposes. The plaintiff asked defense counsel to add the following custodians to the search protoc o l : Sarissa’s general counsel (DiPaolo), Sarissa’s Chief Compliance Office r Patrice ( Patrice Bonfiglio), and Sarissa’s head trader (Pat Garafalo). The p laintiff ’s counsel also asked to add Denner’s assistant. A t this point, defense counsel finally had one of its lawyers inspect Denner’s devices. The inspection confirmed that Den ner did not have any text messages from before O ctober 2021. Counsel checked Denner’s iPad and saw text messages from March 2020, but not earlier. Denner reported that he had not intentionally deleted any text messages relevant to this action and said he d id not understand why his text18

messages from the 2017

- 2018 time period were missing. Denner suggested that that he had upgraded his iPhone and then provided his old phone to one of his sons. Later that month, DiPaolo reported that Denner’s sons had newer d evices acquired after the Bioverativ

- Sanofi transaction. Defense counsel discussed the issue of texts with Sarissa’s general counsel ( DiPaolo ) and its chief compliance officer ( Bonfiglio ) , but did not conduct any formal custodia n interviews. DiPaolo and Bo nfiglio each represented that they adhered to Sarissa’s policy of not texting for business. Defense counsel accepted that representation and decided again against imaging phones. In October 2022, defense counsel finally answered the plaintiffs’ interrogato ries , which included a question about whether the defendants had preserved potentially responsive information. Seven months after learning that Denner had no texts from before October 2021, defense counsel served an interrogatory response that stated the f ollowing: [O]n or around October 2021, Alex Denner replaced his iPhone solely for the purposes of upgrading the device, a process which the Sarissa Defendants believe inadvertently caused his text messages prior to that date to no longer be accessible or r etrievable from his current device. By way of further response, the Sarissa Defendants state that, in the Sari s sa Capital Management LP Compliance Manual and Code of Ethics, Sarissa employees are not permitted to use text messages for official business correspondence (see SAR

- BIVV I D00000183). The Sarissa Defendants have sought to obtain iCloud backups, have contacted Verizon, have conducted searches of Denner’s current iPhone and iPa d devices for backup phone data (including with the assistance of Sarissa’s outside counsel.

. . . ), and have been unavailable to identify any means of recovering any text messages during the relevant time period agreed

- to by the parties. PX 17 at Interrog atory No. 27

.19

The defendants thus asserted that Denner lost his texts on some unidentified date in October 2021, one year before

. Id

. To reiterate, that was a fter Denner had received three litigation hold notices, after this litigation began, after the plaintiff served discovery requests seeking texts , and just before the defendants moved to stay discovery

. The plaintiff understandably viewed Denner’s upgrade story as in herently
susp icious

. During an upgrade, data is transferred to the new iPhone

. 3 Denner and Sarissa’s representation that they contacted Verizon also did not help. When texting on his iPhone, Denner likely used iMessage, which is an over

- the

- top (“OTT”)

me ssaging service that operates through the web. Unlike SMS texts, OTT messages do not run through a cellular carrier’s system , so the carrier has no record of them

. Denner and Sarissa thus offered an explanation for lost texts that made no

sense and took st eps to locate texts that did not help . Denner and Sarissa also sought to minimize the import of the loss by representing that under Sarissa’s Compliance Manual and Code of Ethics, “Sarissa employees are not permitted to use text messages for official busin ess correspondent.” Id. That reference implied that there were no texts to lose.

3 Moving to a New iPhone or iPad , Apple Device Support Tutorials, Apple, https://it

training.apple.com/tutorials/support/sup010 (last visited Jan. 2 6 , 2024). Defense counsel agrees. See PX 19 at 3 (“I have personally replaced my own iPhones twice over the years, and to the best of my knowledge did not lose any data.”).20

Equally important, the defendants’ response was misleadingly incomplete. The response said nothing about DiPaolo’s prior loss of all of his texts due to the post

swimming

- poo l repair. The defendants also provided an incomplete response to another interrogatory. The plaintiff asked defendants to “Identify and describe the methods and/or processes that You used to search for, Identify, collect and review Documents and Communica tions.” PX 17 at Interrogatory No. 28. The response said nothing about the SEC subpoenas, the self

- review of Denner’s phone in 2019, or almost anything we now know about defense counsel’s collection efforts. On November 14, 2022, Sarissa’s Chief Compliance Officer (Bonfiglio) circulated an email to all staff informing them that the Sarissa Hold “initially circulated September 5, 2019, is still in effect, as litigation surrounding the Bioverat i v/Sanofi transaction remains pending.” PX 18. In other words, there was never a time after September 5, 2019, when Sarissa personnel were released from their obligation to retain ESI , incl uding texts. M. The Plaintiff Tries To Obtain Texts From Other Sources The plaintiff made efforts to obtain Denner’s texts fr o m other sources. They subpoenaed Verizon themselves , but Verizon responded that it did not maintain records of Denner’s texts. T hat makes sense for texts from an OTT messaging application. The plaintiff also subpoenaed Lazard, which advised Sanofi on the t ransaction

. Recall that Sands was the primary Lazard banker, and he had known Denner for a decade. PX 21 at 12. The two had a frien dly relationship, and Lazard emails reference21

Denner and Sands’ texting each other. See PX 5, 7, 10. But Lazard could not produce any texts either. Lazard represented that Sands “no longer has the phone that he used during the relevant time period” and “hi s current phone does not have any text messages dating back to the relevant period.” PX 16. N. More Issues With Texts On December 7, 2022, during deposition preparation, Sarissa’s head trader ( Garofalo ) informed defense counsel that he recalled using text s to communicate with Denner . But he said he had no recollection of any text messages relating to Bioverativ. Based on this disclosure, defense counsel finally collected cell phones from DiPaolo, Bonfiglio, and Garofalo.

• DiPaolo’s phone had no messages from before October 9, 2020. He claimed not to know why

.

• Garofalo’s phone had no messages. It was set to delete text message data routinely every thirty days.

• Bonfig l io’s device contained 116,868 text messages. The earliest text message was dated January 30, 2014. None of the search terms hit on any texts. In addition, defense counsel reviewed all of the texts and determined that none are responsive. In short, none of the additional custodians had responsive texts. In February 2023, t he plaintiff pushed for more information about the defendants ’ failure to produce texts

. DX 32. Defense counsel responded with a letter plus a declaration from Denner. In both documents, they stuck to Denner’s story about losing his texts when he upgraded his iPhone . A t the same time, they seemed to know that the story did not make sense

. See PX 19. T he defendants also reported for the first time that DiPaolo, Garafalo, and Bonfiglio did not possess any responsive22

texts. And they reported for the first time that Denner’ s assistant during the relevant period had left Sarissa in September 2018 and that no one had collect ed her phone. O. The Motion For Sanctions On November 14, 2023, the plaintiff moved for sanctions for spoliati ng evidence. The parties briefed the motion, and the court held a hearing on January 4,
2024. During the hearing, defense counsel was unable to answer basic questions about the collection process. To ensure that the defendants had the opportunity to document what they had done, the court directed the defendants to file an affidavit describing their preservation and collection plan and how they carried it out. The defendants filed two affidavits. Defense counsel submitted an affidavit detailing their collection efforts. DiPaolo submitted a separate affidavit in which he recounted the swimming pool story for the first time. DiPaolo also reported that he had notes documenting the advice defense counsel gave for collecting and preserving documents in res ponse to the SEC subpoenas. Sarissa offered to produce the notes under a Rule 510(f) order . The court entered a Rule 510(f) order and authorized the plaintiff to file a sur

- reply. DiPaolo did not address in his affidavit whether any of his data was backed up to the cloud or whether counsel had made any efforts to check his other devices. The court directed defense counsel to file a supplemental affidavit “explaining whether any efforts were made to examine DiPaolo’s other devices, the cloud, or other sourc es for texts after the

. . . swimming pool incident.” Dkt. 213. Defense counsel reported that no data was backed up to the cloud or available from other devices. Defense counsel did not say what they did , or when , to make this23

determination. Their silence suggests that they only took those steps after the court asked. In any event, the failure to provide any detail beyond a clipped response is a further example of defense counsel’s lack of transparency and parsimon y regarding the release of information . T h at approach has undermined their credibility on the spoliation issues. II. LEGAL ANALYSIS The plaintiffs seek sanctions for spoliati ng text messages. Spoliation is the destruction or significant alteration of evidence, the failure to preserve evidence
proper l y for another ’ s use , or the improper concealment of evidence. 4 The plaintiff sought texts , which “ fit comfortably within the scope of materials that a party may request under Rule 34.” 5 Text messages are a form of ESI. 6 Court of Chancery Rule 37(e) addresses sanctions for failure to preserve ESI. It states: If ESI that should have been preserved in the reasonable anticipation of or actual notice of imminent litigation is lost because a party failed to take reasonable steps to preserve it, and it cannot be restored or replaced through additional discovery, the court: (1) upon finding prejudice to another party from loss of information, may order measures no greater than necessary to cure the prejudice; or

(2) only upon finding that the party act ed recklessly or with the intent to deprive another party of the information ’ s use in the litigation, may, among other things: (A) presume that the lost information was unfavorable to the party; or (B) dismiss the action or enter a default judgment. Ct. C h. R. 37(e). Rule 37(e) reflects longstanding public policies. Seven decades ago, the Delaware Supreme Court cited the maxim that “everything will be presumed against the despoiler” and explained that it is “the duty of a court

. . . to adopt a view of th e facts as unfavorable to the wrongdoer as the known circumstances will reasonably admit.” Equitable T

r. Co. v. Gallagher , 102 A.2d 538, 541 (Del. 1954). Imposing sanctions for spoliation embodies the more general policy that “[n] o one shall be permitted t o profit by his own fraud, or to take advantage of his own wrong, or to found any claim upon his own iniquity, or to acquire property by his own crime.” Riggs v. Palmer , 22 N.E. 188, 190 (N.Y. 1889). Court of Chancery Rule 37(e) closely resembles Federal Rule of Civil Procedure 37(e) , as amended in 201 5 , but with changes to conform to Delaware law and Chancery practice. The federal rules first addressed the preservation of ESI in 2006, but that version of Rule 37(e) proved unsatisfactory . D ifferent f ederal courts reaching different conclusions “ about how to determine when sanctions were warranted, what standards of culpability should apply to different kinds of sanctions, and what types of sanctions should be ordered. ” Tanya Pierce, Righting the Ship: What Courts Are Still Getting Wrong About Electronic Discovery, 72 SMU L. Rev. 785, 787 (2019)

.25

The federal rules were amended in 201 5 to provide a clearer and more consistent standard for the federal courts. Federal Rule 37(e) now states: If electronical ly stored information that should have been preserved in the anticipation or conduct of litigation is lost because a party failed to take reasonable steps to preserve it, and it cannot be restored or replaced through additional discovery, the court: (1) upon finding prejudice to another party from loss of the information, may order measures no greater than necessary to cure the prejudice; or (2) only upon finding that the party acted with the intent to deprive another party of the information’s use in the litigation may: (A) presume that the lost information was unfavorable to the party; (B) instruct the jury that it may or must presume the information was unfavorable to the party; or (C) dismiss the action or enter a default judgment. Fed. R. Civ. P. 37(e ). The Advisory Committee notes offer extended commentary to guide its interpretation and application. See F ed . R. C iv . P. 37(e) advisory committee ’ s note s [hereinafter AC Notes]

. The re are two difference s between current Court of Chancery Rule 37(e) and

c urrent Federal Rule 37(e) . One is that Court of Chancery Rule 37(e) omits the reference to instructing a jury that it “may or must presume the information was unfavorable,” for the obvious reason that the Court of Chancery does not have juries. 7

7 Technically, that is an overstatement. The Court of Chancery has the discretionary authority to empanel a jury to try discrete factual issues

. 10 Del. C. § 369 (“When matters of fact, proper to be tried by a jury, arise in any cause depending in Chancery, the Court of Chancery may order such facts to trial by issues at the Bar of the Superior Court.”) . Today, that power is largely vestigial. S ee Preston Hollow Cap

. LLC v. Nuveen LLC , 216 A.3d 1, 11 n. 64 (Del. Ch. 2019) (“ [T] o the extent a jury in the Court of Chancery is not extinct, it is a vestigial structure, more evocative of the human appendix or coccyx than that vital organ,26

The feder al rule nevertheless provides insight into the types of inferences that a court can draw. First, the court might hold that when acting as factfinder, it may presume the information was unfavorable to the party when considering evidence at trial. Alternatively, a court might hold that when acting as factfinder, it will presume that the information was unfavorable to the party when considering evidence at trial

. The other difference between current Court of Chancery Rule 37(e) and current Federal Rule 37(e) is the mental state required for imposing the identified sanctions. The Delaware Supreme Court held in 2006 that a court must make an evidence

- based “finding of intentional or reckless destruction of evidence as a predicate to an adverse inference

. . . . ” Sears, Roebuck & Co. v. Midcap , 893 A.2d 542, 550 (Del. 2006)

. Consistent with Sears , Court of Chancery Rule 37(e) authorizes the court to impose sanctions requiring a culpable mental state if the party “acted recklessly or with the intent to deprive another party of the information ’ s use in the litigation

. ” Ct. Ch. R. 37(e) (2)

. The federal version requires that the party have acted “with the intent to

the Superior Court petit jury.”) ; Getty Ref. & Mktg. Co. v. Park Oil, Inc., 385 A.2d 147, 151 (Del. Ch. 1978), aff ’

d , 407 A.2d 5 33 (Del. 1979) ( observing that “[t]he old procedure of framing of issues by the Court of Chancery for jury trial is now probably outmoded and this Court is certainly not equipped to hold jury trials itself even if permissible.”)

. Furthermore, “[a] jury tri al in Chancery is advisory only. An advisory jury verdict which may be disregarded by the Chancery judge is not entirely equivalent to a jury verdict at law.” Getty , 385 A.2d at 151 ; accord Scotton v. Wright , 122 A. 541, 542 (Del. Ch. 1923) (“ [T]h e verdict of the jury on an issue sent by the Court of Chancery to be tried at the bar of the Superior Court, is not binding on the Chancellor; [] the verdict of the jury is only advisory. . .

. ”). Presumably in a hypothetical case where the Court of Chancery empow ered an advisory jury, the court would have the inherent authority to grant the type of instruction contemplated by Federal Rule 37(e)(2)(B). Given the cosmic rarity of this possibility, Chancery Rule 37(e)(2) streamlines practice by omitting it

depriv e another party of the information’s use in the litigation.” Fed. R. Civ. P. 37(e)(2). A. The Threshold Issue Of Timing Before considering the motion on its merits, the defendants have raised a threshold question of timing. The y argue that the court should no t consider the motion now, maintaining that the Court of Chancery generally make s spoliation findings just before or after trial. T he defendants have collected examples to support that contention , 8 but their examples are just that. They do not establish a general rule, much less a requirement. As part of its case management authority, a trial court has discretion regarding when to address motions. “Delaware trial courts have inherent power to contro l their dockets.” Solow v. Aspect Res., LLC , 46 A.3d 1074, 1075 (Del. 2012). That authority includes determining how to proceed for the “orderly adjudication of claims.” Unbound P ’

just, speedy and inexpensive determination of every proceeding.” Ct. Ch. R. 1. Commenting on the sibling federal rule, a leading treatise states that “[t]here probably is no provision in the federal rules that is more important than this mandate. It reflects the spirit in which the rules were conceived and written, and in which they should be int erpreted.” 4 Charles Alan Wright, Arthur R. Miller & Adam N. Steinman, Federal Practice and Procedure § 1029 (4th ed.), Westlaw (database updated Apr. 2023). Court of Chancery Rule 16(a) similarly contemplates that a court may take steps to “formulat[e] a nd simplif[y]

. . . . the issues” and to address “[s]uch other matters as may aid in the disposition of the action.” Ct. Ch. R. 16(a)(1), (5). The same authoritative treatise explains that “case management [is] an express goal of pretrial procedure.” 6A Ch arles Alan Wright, Arthur R. Miller & Mary Kay Kane , Federal Practice and Procedure § 1521 (3d ed.), Westlaw (database updated Apr. 2023). To that end, the Advisory Committee’s note to the federal rule emphasizes the need for “a process of judicial managem ent that embraces the entire pretrial phase.” Fed. R. Civ. P. 16 advisory committee’s note to 1983 amendment. The commentary recognizes that “[t]he timing of any attempt at issue formulation is a matter of judicial discretion.” Id. Rule 37 “does not contai n any specific reference to the timing of the filing of a motion seeking spoliation sanctions.” Goodman v. Praxair Servs., Inc. , 632 F. Supp. 2d 494, 506 (D. Md. 2009). A review of federal decisions suggests that federal courts primarily encounter the prob lem of parties raising spoliation issues too late, rather29

than too early. 9 For that to be a major concern undercuts the defendants’ argument that spoliation issues should wait until trial. When to address a spoliation issue depends on a variety of factor s, including the nature of the issue, the stage of the case, the court’s ability to provide case

- specific relief , and any scheduling order that might apply. 10 If a party seeks an order compelling the defendants to provide additional discovery or to pay for the movant to conduct additional discovery, then it would be foolish to defer th e motion until trial. If a ruling on the motion will help the parties prepare for trial or limit the issues to be addressed at trial, then it often will make sense to address the motion before trial. If the motion turns on evidentiary issues that the court will evaluate at trial , then it will make sense to defer the motion until trial. Ultimately, the decision rests in the discretion of the court based on the facts of each case

. Here, the plaintiff seeks sanctions that will frame the issues for trial. The plaintiff asks for a combination of adverse inferences and preclusion orders. Whether the court grants the requested sanctions or imposes others will determine how the

June 8, 1999) (collecting authorities). In those settings, courts have acknowledged that “spoliation sanctions motions often follow o nly where extensive ESI recovery efforts have failed, or after forensic review gives the movant a much better idea of the quantity and nature of unproduced, deleted ESI.” Steves & Sons, Inc. v.

parties plan for trial and present evidence. T he proper time to consider the plaintiff’s motion is now. B. The Rule 37(e) Analysis The federal courts have established a step

- by

- step framework for analyzing spoliation issues under Rule 37(e)

. See Thom as J. Joyce, Finding Prejudice from Lost E SI : An Analysis of Courts ’ Standards Under Amended Federal Rule of Civil Procedure 37(e) , 71 Okla. L. Rev. 979, 980

– 81 (2019) (collecting cases). This decision adopts and applies th at framework.
1. Was There A Duty To Preserve The Text s? The first question is whether the ESI “should have been preserved.” Ct. Ch. R. 37(e). “Rule 37(e) does not apply

. . . when information or evidence is lost before a duty to preserve attaches.” Living Color , 2016 WL 1105297, at * 4. “A party in litigation has an affirmative duty to preserve potentially relevant evidence.” Shawe v. Elting , 157 A.3d 142, 150 (Del. 2017). A party also must preserve potentially relevant evidence as soon as the party either actually anticipate s litigation 11 or reasonably should have anticipated litigation. 12 The latter inquiry is an

. 14 In this case, at a minimum, Denner and Sarissa had a duty to preserve evidence starting on February 21, 2018, when Bioverativ’s general counsel circulated the Bioverativ Hold. The duty undo ubtedly arose much earlier, because litigation involving M&A transactions is sufficiently common that Denner and Sarissa should have reasonably anticipated litigation challenging the Bioverativ

- Sanofi transaction well before that. It would be easy to find that Denner and Sarissa’s duty to preserve evidence arose in May 2017, when Denner caused Sarissa to rapidly accumulate a large position in Bioverativ’s stock after Sanofi approached Denner and Posner about buying Bioverativ at a price of $90 per share. Bu t such a finding is not necessary to resolve the issues in the case. Relying on the Bioverativ Hold is sufficient. 15 The duty to preserve evidence extended to all of the Sarissa custodians at issue on this motion. F our of the custodians were obviously key players in Sarissa’s

. Another obvious custodian was Denner’s personal assistant , who would pos sess many of Denner’s documents. The duty to preserve evidence extended to the ESI at issue on this motion. The preservation obligation extended to evidence in Denner or Sarissa’s possession, custody, or control. ESI on Denner’s personal device was plainly within his possession, custody, or control.

Mar. 27, 2020) ; see also Alter v. Rocky Point Sch. Dist ., 2014 WL 4966119, at *10 (E.D.N.Y. Sept. 30, 2014) (“ Finally, Defendants claim that they were not obli ged to preserve work

- related ESI which employees such as Defendant Superintendent Ring utilized on their personal computers. However, to the extent that the School District employees had documents related to this matter, the information should have been pr eserved on whatever devices contained the information ( e.g. [,] laptops, cellphones, and any personal digital devices capable of ESI storage.”)

. See generally The Sedona Conference Commentary on BYOD: Principles and Guidance for Developing Policies and Meet ing Discovery Obligations , 19 Sedona Conf. J. 495, 528 (2018) ( “It should come as no surprise that ESI that falls within the scope of discovery is often stored on mobile devices. Organizations cannot ignore their discovery obligations merely because a devi ce containing unique, relevant ESI is also used for personal purposes.” );35

Eliminating any doubt, t he Biover a tiv Hold, the Sanofi Hol d, and the Sarissa Hold explicitly encompassed texts and expressly extended to personal devices as well
as company - issued devices

. When outside counsel advised DiPaolo about how to implement the Sarissa Hold, they specifically discussed texts and personal devices. Denner and Sarissa therefore had an obligation to preserve the lost texts starting at least as early as February 21, 2018 (though undoubtedly that duty arose much earlier). That satisfies the first element of the Rule 37(e) test.
2. Are The Texts Los t? The second issue is whether the ESI “is lost ” and “cannot be restored or replaced through additional discovery.” Ct. Ch. R. 37(e). “Information is lost for purposes of Rule 37(e) only if it is irretrievable from another source, including other custodian s.” 17 “Because [ESI] often exists in multiple locations, loss from one source may often be harmless when substitute information can be found elsewhere.” AC Notes. The plaintiff has not shown that Bonfiglio’s texts are lost. Her device contained 116,868 text messages going back to January 30, 2014. Defense counsel has determined that none of her texts are responsive, but that is a different issue than spoliation. There was no failure to preserve Bonfiglio’s te xts, so this decision does not discuss her further.

Everyone agrees that the other custodians’ texts are lost. The defendants do not argue that the plaintiff could obtain the ir texts from other sources. The plaintiff does not contend that the defendants co uld recover the ir texts by engaging in remedial efforts such as by restoring backup tapes or searching unstructured data

. Denner and Sarissa might have avoided or mitigated a sanctions ruling by coming forward with other locations where the texts might be found. Given how thoroughly iMessage backs up texts to the cloud and synchs across devices, it is hard to believe that Denner, DiPaolo, and Garafalo successfully deleted all texts across all devices. But everyone agrees that they achieved that feat. This is also not a case where discovery from other parties can fill the gap. After learning that Sarissa could not produce any responsive texts, the plaintiff subpoenaed Verizon, Denner’s cell phone provider. Verizon responded that it did not maintain records o f Denner’s texts . To reiterate, a cellular provider will not have records for an OTT application like iMessage. The plaintiff also subpoenaed Lazard, but Lazard could not produce any texts either. Lazard represented that Sands “no longer has the phone tha t he used during the relevant time period” and “his current phone does not have any text messages dating back to the relevant period.” PX 16. Deposition testimony is not a sufficient substitute. Occasionally an alleged spoliator can testify with a sufficie nt degree of specificity that deposition testimony will suffice to replace the lost information. E.g. , Floeter v. City of Orlando , 2007 WL 486633, at *6 (M.D. Fla. Feb. 9, 2007) ( denying sanctions where spoliator testified in37

such detail about the type , nu mber, and content of lost emails that the trier of fact did not need to see the emails to understand their contents ). That is the exception, not the rule. When custodians cannot recall the details of the texts, whom they texted, or other key information, t hen depositions do not remedy the loss of evidence. Skanska USA , 340 F.R.D. at 187. During his deposition, Denner’s memory repeatedly failed him.

• He had no memory of any phone calls with Sands of Lazard in early May of 2017 about Sanofi’s interest in Bioverativ

. PX 21 at 6.

• He had no recollection of Sanofi making its initial expression of interest at about a 66% premium to market. Id. at 9

.

• He could not recall a meeting with Sands of Lazard in May 2017. Id. at 20. Nor could he recall generally meeting with Sands during that period. Id. at 21

– 22.

• He could not recall calls a series of calls with Sands during May 2017. Id. at 28

– 35, 50.

• He did not recall any discussions with anyone about the short

• He did not recall a meeting with Sands in October 2017. Id. at 63.

• He did not recall any substantive conversations with S ands during October 2017. Id. at 64

– 65.

• He could not recall whether “us” meant “Sarissa” or ‘Bioverativ” and “them” meant “Sanofi.” Id. at 66.

• He did not recall discussions with Sands in January 2018. Id. at 78

– 79.

• He did not recall attempting to revise the proxy statement to assert that Posner reported to each director about Sanofi’s original offer. Id. at 87.38

Add to this that the defendants ha ve provided information about the spoliation belatedly and begrudgingly. Testimony from defense witnesses will not suffice. The texts are well and truly lost. That satisfies the second element under Rule 37(e).
3. Were The Texts Lost Due To A Failure To Take Reasonable Steps

To Preserve Them? The third question is whether the ESI was lost “because a party failed to take reasonable steps to preserve it.” Ct. Ch. R. 37(e). ESI discovery involve s five fundamental steps: (1) identification, (2) preservation, (3) collection, (4) review, and (5) production. DR Distribs

. , LLC v. 21 Century Smoking, Inc. , 513 F. Supp. 3d 839,
923 (N.D. Ill. 2021). 18 The issues here are identification and preservation. When a duty to preserve evidence arises, a party must act reasonably to
preserve the information that it knows, or reasonably should know, could be relevant to the litigation, including what an opposing party is likely to be request. 19 The standard is reasonableness. Partie s need not “preserve every shred of paper, every e

mail or elec tronic document, and every backup tape.” Zubulake IV , 220 F.R.D. at 217

.

18 Judge Iain Johnston’s decision in DR Distributors takes a deep dive into the discovery process with a particular focus on ESI and attendant obligations. It also provides helpful citations to authoritative treatises and other sources. The analysis in DR Di stributors is spot on for Delaware cases.

19 See In re Shawe & Elting LLC , 2016 WL 3951339, at *16 (Del. Ch. July 20, 2016) , aff ’ d sub nom. Shawe v. Elting , 157 A.3d 142 (Del. 2017) ; accord Steves & Sons , 327 F.R.D. at 107 (“ Once a party reasonably anticip ates litigation, it must preserve what it knows, or reasonably should know, is relevant in the anticipated action, is reasonably calculated to lead to the discovery of admissible evidence, or is reasonably likely to be requested during discovery.” ) (cleane d up).39

Taking reasonable steps to preserve evidence requires first taking reasonable steps to identify the information that should be collected and preserved

. See Skanska USA , 340 F.R.D . at 186. Th at process requires “locating the relevant people and the locations and types of ESI.” DR Distribs. , 513 F. Supp. at 927. “T he relevant people are the individuals who have custody of the relevant ESI or the ability to obtain the ESI. Counsel mu st interview them to learn the relevant facts regarding ESI and to identify, preserve, collect, and produce the relevant ESI. ” Id. “The relevant locations are those places where the ESI can be found so that it can be both (a) preserved and (b) collected an d produced. Although both are necessary, preserving ESI is distinct from collecting and producing ESI.” Id. Identifying custodians and locations requires an intentional and systematic approach that includes custodian interviews. Id. at 924. As with an initi al client interview, a reasonable custodian interview can require counsel to cross

- examine the client and test the accuracy of the client ’ s response to document requests to ensure that all appropriate sources of data have been searched and that responsive ESI has been collected

— and eventually reviewed and produced. Simply relying on a client's say so may not be reasonable. And like an initial client interview, the custodian interview can be an iterative process, requiring follow up. Id. at 927 (citations om itted). “[T] the custodian interview is not merely a theoretical best practice. Instead, like the initial client interview, a proper and thorough custodian interview is mandated by the Federal Rules of Civil Procedure and the Rules of Professional Conduct

. ” Id. at 926

– 27. The same is true under this Court’s rules. After identifying the reasonably likely sources of information, the party must take reasonable steps to collect and preserve it

. “Though a party need not preserve40

all documents in its possession

— again, perfection is not the standard

— it must preserve what it knows and reasonably ought to know is relevant to possible litigation and is in its possession, custody, or control.” Id. at 92 9. When considering what is reasonable, a court “should be sensitive to the party ’ s sophistication with regard to litigation in evaluating preservation efforts; some litigants, particularly individual litigants, may be less familiar with preservation oblig ations than others who have considerable experience in litigation.” AC Notes. For an organization, s imply circulating a litigation hold is not enough. 20 The organization must take steps to ensure that the recipients of the hold understand what it means and abide by it

. 21 The organization also must suspend or modify

a. The Failure To Take Reasonable Steps In Response To The

Bioverativ Hold Under these principles, Denner and Sarissa failed to take reasonable steps to
preserve ESI after receiving the Bio v erativ Hold . Starting on February 21, 2018 , Denner and Sarissa had a legal duty to preserve evidence, including ESI , relating to the Bioverativ

- Sanofi t ransaction. As a highly sophisticated party and the principal of an activist hedge fund , Denner was obligated to consult with counsel about his preservation obligations, identify likely sources of information, and take steps to preserve them. After Denner received the Bioverativ Hold, he should have met with DiPaolo to identify the key individuals at Sarissa who were involved with the t ransaction, including Sarissa’s trading in Bioverativ stock. At a minimum, those indi viduals would have included Denner himself, DiPaolo, and Garofalo , the head trader who carried out Sarissa’s purchases. They logically should have considered Bonfiglio as Chief Compliance Officer , but her omission was not

- consequential

.44

Denner and DiPaolo also should have identif ied the key locations where data could be kept. Through that evaluation, they should have identified Denner’s assistant as a custodian. Eighteen months later, Denner and DiPaolo identified Denner’s assistant as a custodian in respon se to the SEC subpoenas. They should have figured that out in February 2018. After identifying those five custodians, Denner and Sarissa should have taken steps to preserve ESI, including by imaging phones or backing up their data

. The Bioverativ Hold expr essly extended to ESI on personal phones. In a world where people primarily communicate using personal devices, it will almost always be necessary to image or backup data from phones. If Denner and Sarissa had proceeded in th at fashion, they would have le arned that Garafalo had set his phone to delete texts automatically after thirty days and could have instructed him to turn off that function and take steps to preserve his data. Texts from before the date he turned off the auto

- delete function would have been lost, but Denner and Sarissa would have known about the lost texts in February
201 8 and could have investigated what other sources of data were available at that time. Perhaps they would have come to the same conclusion that they reached in December 2 022, when they finally looked at Garofalo’s phone , and decided his texts were irretrievably lost. If they had acted earlier, they would have had more alternatives. If Denner and Sarissa had proceeded in that fashion, they would now have data from t he phon es belonging to Denner, his assistant, and DiPaolo. Those texts45

were lost because Denner and Sarissa failed to take reasonable steps to identify and preserve ESI in response to the Bioverativ Hold.

b. The Failure To Take Reasonable Steps In Response To The Sa nofi Hold Just as Denner and Sarissa failed to take reasonable steps to preserve ESI after receiving the Bioverativ Hold, they also failed to take reasonable steps to preserve ESI after receiving the Sanofi Hold on March 15, 2018. The steps that should hav e been taken after the Sanofi Hold are identical to the steps that should have been taken after the Bioverativ Hold, with the additional qualifier that the second hold should have made the necessity of those steps all the more apparent. If Denner and Saris sa had taken those reasonable steps, it would not have made a difference for the texts on Garofalo’s phone. It would have made a difference for the phones belonging to Denner, his assistant, and DiPaolo, where the texts would have been preserved. Those tex ts were lost because Denner and Sarissa also failed to take reasonable steps to identify and preserve ESI in response to the Sanofi Hold.

c. The Failure To Take Reasonable Steps To Implement The Sarissa Hold In addition to failing to take reasonable steps to preserve ESI after the Bioverativ Hold and the Sanofi Hold, Denner and Sarissa failed to take reasonable steps to implement the Sarissa Hold. DiPaolo issued the Sarissa Hold on September 5, 2019, after Sarissa received the SEC subpoenas on September 4. DiP aolo consulted with outside counsel about implementing the hold , yet DiPaolo and outside counsel failed to take reasonable steps to implement the hold.46

If Denner and Sarissa had fulfilled their preservation obligation after the Bioverativ and Sanofi Holds, then Sarissa already would have had images of , or backed up data from , those phones and could have continued to preserve them. They also would have already had an image of, or backed up data from, Denner’s assistant’s phone, which they could have continue d to preserve . Denner and Sarissa’s failures to respond to the earlier holds prevented them from responding properly to the Sarissa hold. Taking the Sarissa Hold in isolati on, Denner and Sarissa would not have breached their preservation obligations as to Denner’s assistant’s phone, because she left Sarissa in September 2018. One year later, h er phone was no longer in Denner or Sarissa’s possession, custody, or control, so t hey did not have an obligation to
preserve it . That does not mean that Denner and Sarissa had no obligation to identify and preserve other sources where the assistant’s data might have been maintained. They had an obligation to preserve ESI then in existen ce. But they did not have a duty, at that point, to secure the phone of an employee who had departed one year before. For purposes of Garafalo , the analysis of the Sarissa Hold is the same as the B i overativ and Sanofi Holds. Denner and Sarissa breached the ir preservation obligations by not identifying Garafalo , not instructing him to turn off his auto

- delete function, not taking steps to image his phone or preserve his data, and not looking for other sources where his lost data could have been preserved.47

M ost significantly, Denner and Sarissa failed to fulfill their preservation obligation by not imaging or backing up data from Denner’s and DiPaolo’s phones

. That occurred because DiPaolo seems to have pushed outside counsel to “table” the collection and ima ging of personal devices by stressing that Sarissa’s policies prohibited using text for business and by representing that he reviewed Denner’s phone and did not identify responsive texts. To fulfill their own obligations, outside counsel needed to be more assertive.

“ Relying solely on the client to identify the universe of relevant information, without reasonable inquiry to verify that the client accurately captured that universe, can lead to sources of information being overlooked. ” 26 “ A n attorney may not simply rely on custodian self

- collection of ESI. Instead, counsel must test the accuracy of the client ’ s response to document requests to ensure that all appropriate sources of data have been searched and that responsive ESI has been col lected

— and eventually reviewed and produced.” 27 Self

- collection of documents is particularly risky, because

Outside counsel should have given little weight to DiPaolo’s representation that no one used texts because it was contrary to Sarissa policy. Outside counsel should have reviewed both Denner’s phone and DiPaolo’s phone. A reasonable preservation effort would have resulted in counsel imaging or backing up both phones. By failing to take these steps, Denner and Sarissa breached their duty to preserve evidence. Denner and DiPaolo also breached their preservation obligation by failing to follow outside counsel’s i nstructions about preserving evidence

. Despite mistakenly tabling the collection and imaging of personal dev i ces, outside counsel gave DiPaolo and Sarissa explicit advice about preserving texts. At two successive meetings, outside counsel asked for users to preserve text messages and check with counsel b efore buying a new phone and transferring data to a new device.

If Denner and Sarissa had taken those reasonable steps, texts from Denner and DiPaolo would still exist. Those texts were lost because Denner and Sarissa failed to take reasonable steps to identify and preserve ESI in response to the Sarissa Hold.

d. The Failure To Take Reasonable Steps To Preserve Documents In Response To This Litigation Finally, Denner and Sarissa failed to take reasonable steps to preserv e documents in response to this litigation. The plaintiff filed this case in December
2020. Denner and Sarissa did not do anything to identify and preserve sources of ESI until November 2021, after the court denied the defendants’ motion to stay discovery. Serendipitously for Denner, his texts disappeared just weeks before. After the plaintiff filed this litigation, all of the defendants had an obligation to identify potential sources of evidence and take steps to preserve them. For Denner and Sarissa, tha t meant reviewing what had already been collected, evaluating what else should be collected, and taking steps to preserve that evidence. As part of that process, defense counsel should have imaged or backed up Denner ’s and DiPaolo’s phones. That did not ha ppen. The affidavits that DiPaolo and defense counsel submitted show no meaningful efforts to identify and preserve potential sources of evidence until November 2021, after the court denied the defendants’ motion to stay. At that point, defense counsel che cked what existed from the SEC collection in 2019, but otherwise remained passive. Rather than taking affirmative steps to identify custodians and locations, Defense counsel waited for the plaintiff to identify sources.50

If defense counsel had acted when t he plaintiff filed this litigation, the y would have determined that no one ever imaged Denner and DiPaolo’s phones as part of the SEC production. Defense counsel should have promptly informed the plaintiff about the loss of DiPaolo’s data and taken steps t o image Denner’s phone. Working collaboratively, the parties might have agreed on other steps to preserve data and avoid another mishap like DiPaolo’s errant repair after the pool cleaning incident. Denner’s data would have been preserved well before Octob er 2021, when his texts

— but seemingly no other data

— were permanently and irretrievably lost. In short, texts were lost because Denner and Sarissa failed to take reasonable steps to identify and preserve ESI after this litigation was filed.

e. The Failure To Provide Timely Disclosure When defending their conduct, the defendants and their counsel have stressed what they did after November 2021, when they began considering their discovery obligations. They have also stressed the efforts they took after the plai ntiff informed the defendants in June 2022 that Denner sent texts relating to Bioverativ. That was too late and too little. In their post

- November 2021 and post

- June 2022 efforts, the defendants were reactive. Instead of seeking to fulfill their discovery obligations, they sought to respond to the plaintiff’s inquiries. The defendants had an independent obligation to identify and preserve evidence. They did not take reasonable steps to fulfill it. In their post

- November 2021 and post

- June 2022 efforts, def ense counsel failed to provide timely and candid information to the plaintiff. It was not until October 2022 that defense counsel revealed how Denner had lost his texts. That information51

should have been provided shortly after March 2022, when defense counsel determined that Denner had no texts on any of his devices from before October 2021. Defense counsel was all the more dilatory in providing infor mation about other custodians. In June 2022, the plaintiffs asked about DiPaolo, Garafalo, Bonfiglio, and Denner’s assistant. It took until February 2023

— eight months later

— for d efense counsel to provide any information about those custodians, and at that point defense counsel offered no explanation for DiPaolo not having any texts. Even in January 2024, when the court held a hearing on the sanctions motion, defense counsel could
not provide any explanation the absence of DiPaolo ’s texts. No one addressed t hat issue until the court ordered defense counsel to provide an affidavit describing their collection efforts. Defense counsel described what they had done, and DiPaolo provided a separate affidavit in which he described the swimming pool incident and subs equent repair gone wrong

. , 981 A.2d at 1187 (calling for “early and, if necessary, frequent communications among counsel” regarding ESI). A problem like spoliation rapidly festers. Defense counsel should have disclosed it earlier and with greater cando r. 4. Determining The Appropriate Sanction The final issue is the appropriate sanction. Like its federal counterpart, Court of Chancery Rule 37 (e) authorizes sanctions to cure prejudice, then conditions an adverse inference or a default judgment on a culpable mental state. The Advisory52

Notes to the federal rule observe that sanctions for curing prejudice should not include or have the same effect as an adverse inference or a default judgment unless the requisite mental state is shown. Rule 37(e) establishes a framework for ESI

- related sanctions that requires prejudice before sanctions can be imposed. Rule 37(e)(i) does not identify the possible sanctions that could be warranted , but t he Advisory Notes to the federal rule refer to orders forbidding a party from putting on certain evidence, permitting other parties to present evidence , or authorizing arguments to the factfinder about the loss of evidence

. Delaware decisions have identified additional possibilities, including orders establishing certa in facts as true, precluding the use of certain evidence, striking particular pleadings or claims , modifying the burden of proof for particular issues, allowing additional discovery, entering default judgments, or awarding attorneys ’ fees and costs. See Ct . Ch. R. 37(b); Fortis Advisors, LLC v. Dematic Corp ., 2020 WL 6784129, at *3

– 4 (Del. Super. Nov. 18, 2020) ; Terramar Retail Ctrs. , LLC v. Marion #2

- Seaport Tr. U/A/D June 21, 2002 , 2018 WL 6331622, at *14 (Del. Ch. Dec. 4, 2018). Rule 37(e)(2) specifies a mental culpability requirement for two sanctions. Under that rule, a court may only presume that the lost information was unfavorable or enter a default judgment if a party “acted recklessly or with the intent to deprive another party of the information’s use in the litigation.” Ct. Ch. R. 37(e)(2). Here, the plaintiff asks that the court to :

• p resume Denner’s stock purchases were motivated by Sanofi’s initial expression of interest;53

• p reclude any testimony, from fact witnesses or experts, that would disavow scienter;

• p reclude any testimony about alternative reasons for Sarissa’s trades, such as a preexisting plan;

• i nfer that the destroyed texts would have supported plaintiffs’ argument that the sale process fell outside the range of reasonableness because Denner maneuvered to secure a near

- term sale that would lock in the profits from his insider trading. These sanct ions are sufficiently significant to require both prejudice and a culpable mental state

.
a. Prejudice Rule 37(e)(1) requires that that a party have suffered prejudice before a court will impose sanctions for failing to preserve ESI. Prejudice exists when spo liation prevents a party from obtaining and potentially using relevant evidence. See Paisley Park , 330 F.R.D. at 236. Proving that lost evidence is relevant , however, can be difficult, precisely because the evidence no longer exists. Like its federal coun terpart, Court of Chancery Rule 37(e) does not allocate the burden of proving or disproving prejudice to one party or the other. Instead, “ [t] he rule leaves judges with discretion to determine how best to assess prejudice in particular cases.” AC Notes. Fe deral courts have taken different positions when allocating the burden of showing prejudice. There are three broad positions : (1) the requesting party generally has the burden to show prejudice; (2) the spoliating party generally has the burden of proof to show lack of prejudice; or (3) the spoliating party bears the burden to show non

- prejudice if it acted with a culpable state of mind. Joyce,
supra , at 982.54

The majority rule imposes some level of burden on the requesting party, but decisions vary in the level of burden imposed . All strive not to make the burden too heavy . Joyce, supra , at 983

– 87 (collecting cases) . In a case involving the loss of an entire hard drive, a court required only that the plaintiff explain how the lost evidence could have been relevant to the case. Core Labs. LP v. Spectrum Tracer Servs., L.L.C. , 2016 WL 879324, at *2 (W.D. Okla. Mar. 7, 2016). Another line of cases requires “plausible, concrete suggestions” about what the lost evidence c ould have shown. 28 A more demanding requirement calls for “some evidence regarding the particular nature of the missing ESI

. . . . ” Eshelman v. Puma Biotechnology, Inc. , 2017 WL 2483800, at *5 (E.D. N.C. June 7, 2017). A minority of district courts place the burden on the non

- producing part y to show a lack of prejudice. Joyce, supra , at 987. The rationale for the burden shift is that the spoliating party is better position ed to know what evidence was destroyed and “should not be able to benefit from its wrongdoing.” Joyce, supra , at 987

– 88

. That approach also comports with the Advisor y Committee notes to the federal rule, which suggest it is reasonable for the requesting party to bear the burden when the nature of the lost information is self

- evident , the information seems relatively unimport ant, or the remaining preserved information appears sufficient to meet all parties ’ needs. As a general rule, the Advisory Committee observes that “ [d]etermining the content

- Toledo , 2017 WL 1155743, *1 (D.P.R. 2017) ; Hynix Semiconductor Inc. v. Rambus Inc. , 897 F. Supp. 2d 939, 981 (N.D. Cal. 2012) ( quoting Micron Tech., Inc. v. Rambus Inc. , 645 F.3d 1311, 1328 (Fed. Cir. 2011)).55

of lost information may be a difficult task in some cases, and placing the burden of proving prejudice on the party that did not lose the information may be unfair.” AC Notes. A small number of courts, including the District of Delaware, have analyzed the non

- producing party’s mental state first. Joyce, supra , at 990 , 992

. If there is evidence that the non

- producin g party destroyed evidence intentionally, then the court may infe r that the evidence was unfav o rable, shifting the burden of proof to the

non - p r oducing party to show lack of prejudice. 29 “ The primary justifications for this approach are that only the party engaged in the destruction of evidence can know how much prejudi ce was caused by the spoliation, and it is unlikely that the non

spoliating party will be able to prove what was contained within the destroyed information. ” Joyce, supra , at 990. That is the same rationale for shifting the burden
to the non

- producing part y in the first place, but the additional requirement of showing bad faith narrows the situations when the burden shifts. Based on how Delaware approaches disputes over relevance, a plaintiff seeking to establish prejudice under Rule 37(e) must provide a p lausible explanation as to why the evidence could have been relevant such that the failure to preserve is prejudicial. When a party seeks discovery under Rule 26(b)(1), the party bears an initial burden to “provide some minimal explanation as to why the di scovery satisfies the requirements of relevance and conditional admissibility.” In re Appraisal of Dole

29 E.g. , Ala. Aircraft , 319 F.R.D. at 743

– 44 ; GN Netcom, Inc. v. Plantronics, Inc. , 2016 WL 3792833, at * 9 (D. Del. July 12, 2016).56

Food Co., Inc. , 114 A.3d 541, 551 (Del. Ch. 2014) (collecting authorities). The party opposing discovery then must “show that the explanation is erroneo us and that the Rule 26(b)(1) standard has not been met.” Id. Likewise when showing prejudice from spoliation, the requesting party must provide some minimal explanation as to why the lost ESI could have been relevant and either admissible in its own righ t or reasonably likely to lead to the discovery of admissible evidence. At that point, the party that failed to preserve the ESI must convince the court that the lost material could not have been relevant, would not have been admissible or potentially led to the discovery of admissible evidence, or otherwise could not have been used by the requesting party to its advantage. In this case, the plaintiff has shown prejudice. The extant record is virtually devoid of contemporaneous documents about Sarissa’s pu rchases, yet someone at Sarissa approved them, someone informed DiPaolo so that he could reach out to Bioverativ’s general counsel to ask about them, and someone told the head trader to start and stop buying. There are no substantive internal Sarissa email s about the purchases. The only email that references the purchases involved Denner
encourag ing the head trader to “ [k] eep going.” PX 3. There are no communications about why Sarissa octupled its stake so rapidly, but in internal Lazard notes, the bankers expressed the view that Denner turned down a high offer outright in May 2017 because “Denner would like to build up a stake in the firm prior to selling.” PX 2. Lazard later reported that Sanofi viewed Sarissa’s massive p urchases of stock in57

May 2017 as “a positive for the deal” from Sanofi’s perspective. PX 4. The no

- longer extant texts plausibly could have shed light on all of those issues. The extant record is also virtually devoid of contemporaneous documents from with in Sarissa about Sanofi’s acquisition of Bioverativ . The only substantive internal emails from Sarissa about the acquisition involve Denner a n d DiPaolo discussing the Schedule 14D

- 9, after the deal was signed. T he no - longer

- extent texts inferably would hav e include d exchanges between Denner and Sands about Sanofi’s attempts to engage. The y also inferably would have include d exchanges about the negotiations that Denner led on behalf of Biover a ti v after October 2017. See PX s 5 , 7 , 23 at ’ 15827. If the texts e xisted, the plaintiff could use them to prove their affirmative case. But that is not the only harm the plaintiff has suffered. Denner and Sarissa intend to present testimony at trial about a preexisting plan to purchase stock , such that the timing of Sari ssa’s sudden and significant investment was unrelated to Sanofi’s offer. If the plaintiff had access to contemporaneous texts, the plaintiff could have used the
texts to cross

- examine the defense witnesses and impeach their story. Denner and Sarissa lack any credible response. The plaintiff has pointed to prejudice, and the defendants have not shown that it does not exist.

b. The Sanctions Necessary To Cure The Prejudice Rule 37(e)(1) authorizes the court to impose sanctions as necessary to cure the prejudi ce. For sanctions to alleviate the harm in this case , they must address both of it s dimensions. They must address the lack of evidence that the plaintiff has to prove its affirmative case and compensate for the greater ability of the defendants to testify with impunity.58

To address the first issue, the court will presume at trial that Denner and Sarissa traded based on Sanofi’s initial approach. The court also will presume at trial that the lost texts would have supported plaintiffs’ position that the sale process fell outside the range of reasonableness because Denner maneuvered to secure a near

term sale that would lock in the profits from his insider trading. Both presumptions are rebuttable. Under Delaware Rule of Evidence 301, “[ i] n a civil case, unless a statute or these Rules provide otherwise, the party against whom a presumption is directed has the burden of proving that the nonexistence of the presumed fact is more probable than the existence of the presumed fact .” D.R.E. 301; see Alaska Elec. Pension Fund v. Brown , 988 A.2d 412, 418 n. 19 (Del. 2010) (“Delaware law does not embrace the ‘bursting bubble’ rule adopted by the Federal Rules of Evidence.”). This is a meaningful sanction. Although Delaware decisions assert that presumptions and thei r close cousin

— the burden of proof by a preponderance of the evidence

— merely determine how a judge rules when the evidence is precisely in equipoise, 30 th at is an incomplete description of their effect. Far more often, th ey

30 See In re S. Peru Copper Corp. S ’ holder Deriv

. Litig ., 52 A.3d 761, 792 (Del. Ch. 2011) (asserting that “the burden becomes relevant only when a judge is rooted on the fence post and thus in equipoise

. . . . ”), aff’d sub nom. Ams

. Mining Corp. v. Theriault , 51 A.3d 1213 (Del. 2012); In re Cysive, Inc. S ’ holders Litig. , 836 A.2d 531, 548 (Del. Ch. 2003) ( assertin g that the practical effect of shifting the burden of persuasion under a preponderance standard “is slight” because “ the outcome of very few cases hinges on what happens if

. . . the evidence is in equipoise.”). If allocating the burden of proof was such a non - issue, then it would be strange for it to be an issue of law that warrants reversal when mis

- imposed. Compare State Farm Mut. Auto. Ins. Co. v. Spine Care Del

. , LLC , 238 A.3d 850, 858

determine what happens if there is no credible evidence on a topic , or if there is some credible evidence, but not enough that either side could carry a burden by a preponderance. In each of those common situations, the party favored by the presumption prevails. The party with the burden loses. 31 In this case, the presumption could be outcome

- determinative. The plaintiff has represented that no contemporaneous evidence exists on particular topics. If so, and if the court discredits the testimony of Sarissa’s witnesses, then neither party could carry a burden. The side with the burden loses; the side with the presumption

of De l. , 267 A.3d 996, 1008 (Del. 2021) (rejecting request for reversal based on misallocation of burden of proof).

31 For a concrete example of the latter scenario, assume three equally likely scenarios. With each one

- third likely, none prevails by a preponderance. For a concrete example of the former scenario, recall the debates over appraisal arbitrage and the inability of anyone to prove under the federally imposed system of immobilized reco rd ownership how individual shares were voted. Whoever bore the burden of proof would lose. If an investor bought shares in the public market after the record date, no one could match the shares to a proxy and determine how the shares were voted. If the in vestor bore the burden of proving that those shares were not voted in favor of the merger, then the investor could not seek appraisal. See In re Appraisal of Transkaryotic Therapies, Inc. , 2007 WL 1378345, at *1

– 2 (Del. Ch. May 2, 2007)

. For a more recent example, consider the problem of proving whether a dispositive number of stockholders relied on a material misstatement or omission for purposes of establishing damages for a disclosure claim. As a practical matter, it is impossible to gather first

- hand ev idence about whether thousands of stockholders relied on a particular misstatement or omission. If a class plaintiff bears the burden of proving reliance, then class claims for damages from disclosure claims cannot succeed. See In re Columbia Pipeline Grp. , Merger Litig. , 299 A.3d 393, 494 (Del. Ch. 2023) (“ The only reasonable takeaway from the Dismissal Decision was that the plaintiffs would have to prove reliance, causation, and quantifiable damages. TransCanada ’ s post

- trial argument called attention to t he implications of such a rule

— a practical impossibility to recover class

- wide compensatory damages for breaches of the duty of disclosure. ”).60

wins. Because the defendants spoliated evidence, the plain tiff should prevail in that setting. The presumption thus helps remedy the problem created by the absence of evidence, but it does not remedy the difficulties that the plaintiff will face cross

examining Sarissa’s witnesses w ithout contemporaneous documen ts. To address that issue, the plaintiff asks for preclusion orders, but the court will not go that far. Instead, the court will impose a sanction that this court previously deployed wh en a party engaged in spoliation: raising th at party’s standard of proo f by one level on any issue where th at party has the burden. TR Invs., LLC v. Genger , 2010 WL 541687, at *2 (Del. Ch. Feb. 3, 2010). By way of example, if the defendants would have to prevail by a preponderance of the evidence, they will instead have to pr evail at trial by producing clear and convincing evidence. In Genger , the court went further and held that because the spoliator’s conduct called his credibility into question, he “will be unable to prevail on any material factual issue if the only eviden ce in support of his position is his own testimony.” Id. Under that ruling, “[a]bsent corroborating testimony or documents , [ the spoliator’s] mere word will be insufficient to meet his burden of persuasion.” Id. Although the court could take that additional step in this case, the court will consider the testimony of Sarissa witnesses and give it the weight due, taking into accou nt when the testimony is uncorroborated. Finally, the plaintiff is awarded the reasonable attorneys ’ fees and expenses incurred pursing the spoliation issue, including the correspondence relating to that61

issue, the subpoena issued to Verizon, and the brief ing of the motion. T he parties will exchange information about their respective attorneys ’ fees and costs and attempt to reach accord in good faith. If they cannot agree, the plaintiff may file an application.

c. A Culpable Mental State To remedy the prejudi ce that the failure to preserve ESI caused in this case, the court has awarded sanctions under Rule 37(e)(1) that include presumptions that are adverse to the defendants. Because of the significance of the presumptions , it seems likely that the court only can impose them only if Denner and Sarissa acted recklessly or intentionally. They at least acted recklessly, so that standard is met. Under Delaware law, “[i]ntentional conduct means conduct that a person undertook with a knowing desire or with a conscio us objective or purpose.” Urb. Concepts LLC v. Gruber , 2023 WL 4423978, at *4 (Del. Super. July 7, 2023) (cleaned up) . “Reckless conduct r eflects a knowing disregard of a substantial and unjustifiable risk. It amounts to an ‘ I don ’ t care ’ attitude. ” Id. (c leaned up). For purposes of spoliation, a court can find recklessness when an actor is under a duty to preserve evidence and takes part in the destruction of evidence while being consciously aware of a risk that he or she will cause or allow evidence to be spoiled by action or inaction and that risk would be deemed substantial and unjustifiable by a reasonable person. Beard Rs ch

. , 981 A.2d at 1192

.

i. Denner and DiPaolo Based on the current record, the court could find that Denner and DiPaolo acted intentiona lly in not preserving ESI. At a minimum, they were reckless.62

A party can prove a culpable mental state through either direct or circumstantial evidence. See Skanska USA , 340 F.R.D. at 188; E*Trade Sec., LLC v. Deutsche Bank AG , 230 F.R.D. 582, 59 0 (D. Minn. 2005). A court ultimately looks for evidence of a “serious and specific sort of culpability regarding the loss of relevant ESI.” Paisley Park , 330 F.R.D. at 236 (cleaned up) . This court previous ly found that a party “was at least reckless” in failing to preserve ESI on a personal phone where th e party (i) moved to stay discovery and represented that no potentially relevant information would be in jeopardy, (ii) subsequently lost his phone, (iii) never identified any actions taken to preserve the contents of the phone

— or to even consider that issue

— after the duty to preserve arose and before the phone was lost, (iv) initially represented that he had no text messages and claimed that he generally di d not text for business purposes. Kan

- Di

- Ki, LLC v. Suer , 2015 WL 4503210, at *29 (Del. Ch. July 22, 2015). Here, Denner and DiPaolo engaged in comparable conduct. Both knew about their obligation to preserve texts on their personal devices. Denner receive d three litigation hold notices: the Bioverativ Hold, the Sanofi Hold, and the Sarissa Hold. DiPaolo issued the Sarissa Hold. Each litigation hold discussed the need to take affirmative steps to preserve texts on personal device s . For the Sarissa Hold, ou tside counsel gave DiPaolo specific advice about preserving texts. DiPaolo induced outside counsel to defer gathering texts from personal phones by representing (incorrectly) that Denner did not text and claiming63

that he had personally reviewed Denner’s te xts and not found any relating to Bioverativ. The limited texts that the plaintiff has been able to obtain disprove that. Outside counsel nevertheless instructed DiPaolo that Sarissa employees needed to preserve their texts and to consult with counsel bef ore upgrading their phone. There is no evidence that anyone took any steps to implement that instruction. DiPaolo lost his text s in October 2020. That was after he had personally issued the Sarissa Hold and received instructions from outside counsel on how to preserve
texts. Denner lost his texts in October 2021. That was just after the plaintiff served a document request seeking texts and just before the defendants moved to stay discovery based in part on the assertion that the plaintiff would not suffer a ny prejudice. Both Denner and DiPaolo lost their texts through inexplicable failures of their phones to back up their texts from the cloud. For Denner, that supposedly happened when he upgraded his iPhone, but everyone agrees that an iPhone upgrade does n ot have that effect. For DiPaolo, that supposedly happened after he was personally cleaning his swimming pool, dropped the phone in the water, and then sent it to be repaired. No one has suggested that Denner or DiPaolo lost other data from their phones. Neither have described emotionally crushing losses of beloved family photos. Neither have suggested that they had to rebuild their contacts from other sources or64

repurchase all of their applications. The strange failure to transfer data to their new phones seems only to have affected their texts

. That is a lot to believe, particularly when neither explanation is credible, and when Denner and DiPaolo claim merely to be speculating about how their texts could have been lost. This court previously found a party to be reckless where the party took no steps to preserve devices and “threw up his hands up in bewilderment as to what happened to them

. ” Triton , 2009 WL 1387115, at * 8

. That is basically what Denner and DiPaolo have don e. Both Denner and DiPaolo have averred that they never intentionally deleted any texts . The objective facts speak more loudly. Denner’s failures to recall anything about more memorable issues provide additional reason to question whether he would accurately remember intentionally deleting text s . DiPaolo’s failure to identify texts on Denner’s phone about Bioverativ, when we now know Denne r sent them, provide s additional reason to question whether he would know whether he intentionally deleted texts. Denner and DiPaolo had ample motive to delete their texts. The texts violated Sarissa’s internal policies and federal record keeping laws. The y could have (i) subjected the defendants to fines, (ii) incriminated them in an SEC investigation, (iii) supported the plaintiff’s claims, or (iv) undermined the defendants’ explanations. Denner and DiPaolo also had the opportunity and ability to delete t heir texts, because their devices were never imaged or backed up.65

For purposes of sanctions under Rule 37(e)(2), recklessness is sufficient. For now, the court finds only that Denner and DiPaolo acted recklessly. Both sides may present evidence regarding spoliation at trial. As part of its post

- trial findings, the
court may revisit this issue and evaluate whether Denner and DiPaolo’s conduct went beyond recklessness to reach the level of intentionality.

ii. Sarissa Just as the court could find that Denner and DiPaolo acted intentionality, the court could reach the same finding regarding Sarissa. Here again, the court finds only that Sarissa was at least reckless. There are multiple paths to finding Sarissa acted with culpable intent. The most straightforward i s imputation. When senior officers of an investment firm act with a particular state of mind, Delaware law imputes that knowledge to the firm. 32 Denner is the founder and principal of Sarissa; DiPaolo is its general counsel. When they acted recklessly, at a minimum, to spoliate evidence in a case brought against

Therefore, the court may infer CIBC’s kno wledge of the Special Limited Partner’s and Investment Advisor’s breaches of fiduciary duty.”).66

both Denner and Sarissa, their culpable state of mind is imputed to Sarissa for purposes of the spoliation motion. Garofalo’s actions in failing to turn of f his auto

- delete function are also attribu table to Sarissa. This court has found that the failure to turn off an auto

- delete feature “was at least reckless.” Gener8 , 2023 WL 6381635, at *15

. Federal decisions reach the same conclusion. See , e.g. , Skanska USA , 340 F.R.D. at 185. Garafalo was Sariss a’s head trader, and Sarissa had an obligation to preserve his texts. For purposes of the sanctions motion, Garofalo’s recklessness is attributable to Sarissa.

iii. Culpability Requirement Met The findings regarding recklessness satisfy the requirements of Rule 37(e)(2) for purposes of the sanctions that the court finds necessary to cure the plaintiff’s prejudice. The court therefore need not search for alternative sanctions that would be less w ell suited to the harm the plaintiff suffered. III. CONCLUSION The motion for sanctions based on the failure to preserve ESI is granted . The allocation of burdens and presentation of evidence at trial will conform to the rulings in this decision.
