Summary
Citadel has escalated its legal dispute with Marshall Wace by filing allegations in New York court that the London-based hedge fund is obstructing evidence discovery in a recruitment-related matter. According to Bloomberg, the conflict centers on Daniel Shatz, a former Citadel portfolio manager who joined Marshall Wace in 2024 to establish and lead its credit operation.
The underlying dispute involves competing claims about Shatz's departure and compensation. Shatz has initiated arbitration against Citadel, asserting that the firm wrongfully withheld an eight-figure deferred compensation package following his resignation. Citadel counters that Shatz forfeited this payment by violating his employment agreement and misappropriating confidential information prior to his departure. A New York judge ruled in June that Citadel had legal grounds to obtain relevant records from Marshall Wace to support its position in this arbitration.
Citadel's latest filing alleges that Marshall Wace has deliberately impeded the discovery process over a nearly three-month period. The hedge fund specifically accuses Marshall Wace of refusing to search communications involving senior executives Anthony Clake and Alan Hofmeyr, despite evidence suggesting these executives played central roles in recruiting Shatz and building Marshall Wace's credit division. Citadel is seeking a court order that would expand the scope of document searches and mandate inclusion of these executives' communications.
Marshall Wace has rejected the obstruction characterization. Through legal counsel, the firm stated it has responded to subpoenas "with diligence and good faith," though it declined further public comment on the dispute. The case underscores the competitive tensions inherent in hedge fund recruitment and the enforcement mechanisms available to firms seeking to protect proprietary information and enforce contractual obligations around deferred compensation and non-competition provisions.
