A subpoena against Orrick Herrington & Sutcliffe in a partnership dispute Jones Day initiated must be enforced, the U.S. Court of Appeals for the Ninth Circuit ruled Monday. 

Judges Kim Wardlaw, Sandra Ikuta and Bridget Bade reversed a district court order that denied Jones Days’ petitions to compel Orrick to comply with a summons, which stemmed from international arbitration Jones Day commenced against one of its partners in its Paris office, who allegedly violated an agreement when he left the firm for Orrick in 2019.
