The California Courts lost another great judge this week. Richard M. Mosk served on the California Court of Appeal, but was renowned for a career that spanned three decades of public service working on a host of high profile commissions.

While serving on the Warren Commission, Mosk had the rather unique task of directly investigating the background of Lee Harvey Oswald.

The LA Times reports: “He firmly believed that Lee Harvey Oswald was the lone gunman,” said Matthew Mosk, his son and an ABC News producer. “He did not want to see history distorted by conspiracy theories.”

Mosk also served on Iran-US Claims Tribunal at The Hague. The Tribunal was created following the hostage crisis to resolve issues between the two countries.

The Times reports, “Richard Mosk also served on the Christopher Commission — which investigated the LAPD in the wake of the Rodney King beating — the Los Angeles Board of Inquiry on Brush Fires, the Los Angeles Commission on Judicial Procedures, the L.A. County Law Library board and the Stanford Athletic Board. He also was on the boards of the California Museum of Science and Industry and Town Hall California.”

At CCM, we send our deepest condolences to his family and friends who are mourning his passing, and we salute a long-standing public servant of the California Courts
