San Francisco — A federal appeals court has assigned a committee to investigate workplace conditions after the revelation of sexual misconduct accusations forced a high-profile judge to retire.

Chief Judge Sidney R. Thomas of the 9th U.S. Circuit Court of Appeals named four judges and an employment lawyer to the committee, which will review policies to protect workers.

Thomas said he created the committee on Dec. 17. The day before, 9th Circuit Judge Alex Kozinski announced his retirement after former clerks and others in the legal profession accused him of sexual misconduct.

Thomas did not mention Kozinski by name in announcing the committee, but noted there were rules in place to deal with complaints against federal judges.

“We do have many effective procedures in place to avoid problems in the workplace,” he said in a news release. “But we need to re-examine them, develop better means of communication, and assure our law clerks and staff of a healthy and productive workplace.”

The women who complained about Kozinski included one of his former law clerks, who said confidentiality rules in the judges’ chambers made it impossible for her and other law clerks to seek redress.

The women accused him of improprieties such as showing them pornographic images and groping, in published reports.

Ninth Circuit Judge M. Margaret McKeown will head the committee. Members include Judges Virginia A. Phillips of Los Angeles, Charles R. Breyer of San Francisco and Candy W. Dale of Idaho, and San Diego attorney Abby Silverman, an expert in employment law.
