A District of Columbia judge has refused to force Orrick, Herrington & Sutcliffe to disclose certain internal information to Jones Day, which accused a former longtime practice-leading partner in Paris of breaching his partnership agreement after he departed for the rival law firm two years ago.

Jones Day lawyers asked a District of Columbia Superior Court judge in November to enforce an arbitral subpoena against San Francisco-based Orrick as part of an underlying proceeding involving the former partner. Many of the filings in the court case were redacted, leaving very little information available publicly. A judge sealed a telephonic hearing in April, denying ALM the opportunity to listen to the proceedings.
