Summary
Citadel has obtained a court ruling that allows it to pursue communications from two senior Marshall Wace executives in an ongoing legal dispute over the recruitment of former portfolio manager Daniel Shatz, according to Bloomberg. New York Supreme Court Justice Andrea Masley determined that Anthony Clake and Alan Hofmeyr fall within the scope of Citadel's subpoena and ordered the London-based hedge fund to broaden its search for documents related to Shatz's appointment as global head of credit.

The dispute centres on Citadel's allegations that Shatz improperly accessed and retained confidential firm information before leaving Citadel in 2023 and joining Marshall Wace in 2024. Citadel says the materials included recruitment lists, strategic plans for developing a global credit business and candidate evaluation records. Separately, Shatz has initiated arbitration proceedings, alleging that Citadel withheld an eight-figure deferred compensation package in retaliation for raising concerns about potential securities violations.

Citadel argues that Clake and Hofmeyr played significant roles in recruiting Shatz and in planning Marshall Wace's credit expansion before his official start date. Marshall Wace has disputed the scope of the document requests, stating that it has cooperated with the subpoena process and describing certain demands as unnecessary.

The ruling is the latest development in a broader dispute touching on hedge fund recruitment practices, confidential investment information and deferred compensation, against a backdrop of intense competition for senior portfolio managers and credit trading talent across the industry. Citadel welcomed the court's decision, while Marshall Wace declined to comment.
