Douglas Jae Woo Kim Seeks to Bar Chainalysis Expert from Testifying in Upcoming H
On Friday, December 27, 2024, Douglas Jae Woo Kim filed a motion in the US District Court for the Northern District of California, seeking to exclude the expert testimony of Ryan Gordon from Chainalysis, Inc., along with any evidence derived from the company’s work. The motion comes as Kim prepares for a hearing set for February 3, 2025, at 9:30 AM in San Francisco, overseen by Judge Charles R. Breyer.
The motion articulates concerns regarding Chainalysis’s prior engagement with Kim, alleging that the company violated a professional services agreement by subsequently working with the government in this case. Kim’s legal counsel, Dean D. Paik, contends that Chainalysis had initially agreed not to assist the government in matters related to Kim’s case, a stipulation that was crucial for Kim’s willingness to share confidential defense strategies with the firm.
According to the motion, Chainalysis was engaged by Kim in August 2020 to provide expert witness services related to cryptocurrency transactions central to the charges against him. The company proposed a non-exclusivity agreement that allowed it to work with multiple clients, but Kim’s attorneys insisted on a modification to ensure that Chainalysis would not work on his case while also assisting the government. Chainalysis reportedly accepted this modification.
In January 2021, however, Chainalysis referred Kim to another cryptocurrency expert and did not inform him that it would be providing services to the government in his case. Kim’s team asserts that had they known of Chainalysis’s decision to work for the prosecution, they would not have disclosed sensitive information regarding Kim’s defense strategies.
The filing cites Chainalysis’s actions as a breach of the revised professional services agreement, arguing that the company’s failure to maintain its contractual obligations undermines the integrity of the judicial process. Kim’s attorneys emphasize that Chainalysis’s involvement with the government raises significant ethical concerns, particularly given the confidential information shared during their previous consultations.
The motion highlights that Chainalysis’s actions not only jeopardize the fairness of the proceedings but also conflict with established legal principles that protect confidential communications between expert witnesses and their clients. Kim’s legal team argues that allowing Chainalysis to testify would essentially reward the company for breaching its commitments and undermining the confidentiality of its previous engagements.
In the motion, Kim’s attorneys assert that federal courts possess the authority to disqualify expert witnesses to safeguard the integrity of the legal process and ensure public confidence in judicial proceedings. They contend that disallowing Gordon’s testimony, as well as any evidence linked to Chainalysis’s work, is a necessary step to uphold these principles.
The filing also outlines the nature of the confidential relationship between Kim and Chainalysis, detailing multiple instances where Kim’s counsel shared sensitive strategies and information with Chainalysis’s team, which included discussions about the strengths and weaknesses of the government’s case against Kim. Given the depth of this relationship and the confidential information exchanged, Kim’s attorneys argue that Chainalysis should be disqualified from serving as an expert for the government.
