The Court has before it defendant Youbi Capital (Cayman) GP ("Youbi")'s motion for sanctions against plaintiffs and counterclaim defendants arising out of a discovery issue.[FN1]


Background

Plaintiffs commenced this action in 2021, arising from a dispute concerning the parties' joint venture in creating Youbi to manage investments in cryptocurrency assets. The complaint essentially alleges that while plaintiffs substantially contributed to Youbi's growth from inception to a net asset value of nearly $300 million, the individual defendants have wrongfully deprived plaintiffs of Youbi's profits and have engaged in acts of fraud, breach of fiduciary duty, and conversion.

In response, Youbi filed counterclaims, including misappropriation of trade secrets; breach of confidence under Cayman law; breach of fiduciary duty under Cayman law; aiding and abetting breach of fiduciary duty; conversion; unjust enrichment; and declaratory judgment. In January 2023, the Court denied plaintiffs' motion to dismiss these counterclaims.

In this motion, Youbi asserts that although plaintiffs left Youbi in November 2018, they improperly continued to access Youbi's centralized document database (the "ShareDrive") and downloaded thousands of documents therefrom, including Youbi's trade secrets and confidential strategic materials with information on how to successfully operate a cryptocurrency investment fund.[FN2] According to movant, plaintiffs "engaged with Youbi files on March 28, April 15, and April 27, 2022, as well as March 15, April 11, June 1, June 26, June 27, and August 24, 2023," and used "their unauthorized access to documents from Youbi Share Drive, including a document titled "GP-ELP-NV by project and wallet info.xlsx," for the purposes of this litigation." Youbi contends that "Because of Plaintiffs' deliberate failure to comply with the Court's orders and their misrepresentations regarding their inspection of, and the location of, [*2]Youbi files, Youbi and this Court have been deprived of forensic evidence needed to fully understand where Youbi's stolen files were ultimately moved, or how those files were used. This deliberate misrepresentation and discovery misconduct alone warrants severe sanctions." As a result, it seeks "an order imposing adverse inferences to remedy the prejudice upon Plaintiffs, monetary penalties under 22 NYCRR § 130-1.2, and awarding Defendants their attorneys' fees and costs."

In March 2023, the Discovery Referee appointed by the Court directed plaintiffs to produce an electronic audit log showing what they did with the files from the ShareDrive. Plaintiffs thereafter produced a master file table ("MFT") for the ShareDrive documents on Zhou's laptop. Youbi contends that this was "an incomplete MFT," and that there "various other folders on Zhou's laptop containing Youbi files," but that plaintiffs directed "selective imaging" and "concealed other folder locations and limited Youbi's ability to fully trace Plaintiffs' misappropriation." In response, plaintiffs contend that while they did only produce one file, "On August 5, 2022, Plaintiffs produced all documents downloaded from the ShareDrive, with metadata." Plaintiffs explain that the other files were "copies for purposes of litigation (i.e., work product)" and that they produced "the original set of files as downloaded" but "not any work-product versions of the documents."

In August 2024, the Court entered an Order (that the parties drafted and the Court so-Ordered) directing plaintiffs to produce an audit log (the "Audit Log") from a forensic image of Zhou's computer, which focused upon 42 ShareDrive files that were stored there. The Order states that "Plaintiffs will use the following five forensic artifact types from a forensic image of Plaintiff Zhou's computer for purposes of developing an audit log ('Audit Log') of the ShareDrive files stored on Plaintiff Zhou's computer: 1) shell bags, 2) jump lists, 3) LNK, 4) web history, and 5) a connected USB device analysis."[FN3] There was an option to obtain eight additional files but, according to plaintiffs (and apparently unrebutted by movant), Youbi did not take advantage of this option.[FN4]

In February 2025, plaintiffs produced the Audit Log. According to movant, "Although in response to Defendants' repeated requests for all relevant devices Plaintiffs repeatedly maintained that only one device — a laptop belonging to Zhou — was relevant, the analysis of the Audit Log revealed that Plaintiffs concealed the existence of another relevant device — a removable drive (the 'Removable Drive'). When Defendants' counsel inquired why this device was never disclosed, Plaintiffs' counsel suggested that it was 'not relevant' because it contained 'copies' of the documents downloaded from the Share Drive."

Youbi further contends that at a Court conference on July 2, 2025, "the Court ordered an inspection of the Removable Drive." This is not quite accurate. A review of the transcript of that Court appearance shows that the Court ordered something far more limited: all that the [*3]Court ordered was a review of two files on the "My Passport drive," which appears to be the same thing as the Removable Drive.

Approximately one month later, Youbi's counsel requested "that the Court compel Plaintiffs to complete the court-ordered forensic inspection of Zhou's removeable drive. At the July 2, 2025 conference, Plaintiffs were ordered to conduct a forensic inspection of a previously-unidentified removeable drive aimed at two Youbi Capital files that exist on the device."
