US supreme court chief justice John Roberts is using his annual report on the federal judiciary to highlight the steps the branch has taken to combat inappropriate conduct in the workplace.

In December 2017, Roberts asked that a working group be put together to examine the judiciary’s workplace conduct policies. His request followed news reports about prominent federal appeals court judge Alex Kozinski, who retired following multiple accusations by women, including former law clerks, that he had touched them inappropriately, made lewd comments and showed them pornography.

The working group of judges and judiciary officials that Roberts asked be convened issued a report in June, finding that inappropriate conduct is not widespread among the judiciary branch’s 30,000 employees but also is “not limited to a few isolated instances”. The group offered a range of recommendations for further action.

Roberts, in his New Year’s Eve report issued just before midnight, endorsed those recommendations, which focus on revising the codes of conduct the judiciary has for judges and employees, streamlining the process for identifying and correcting misconduct, and expanding training programs aimed at preventing inappropriate behavior.

Roberts did not say anything in the report about the sexual assault allegations that nearly derailed the confirmation of the court’s newest justice, Brett Kavanaugh, and enraged many. In testimony before senators in September, psychology professor Dr Christine Blasey Ford alleged that a drunken Kavanaugh violently restrained her and attempted to rape her at a party when they were teenagers. Kavanaugh denied the allegations.

Also, last year, before he became a supreme court nominee, Kavanaugh hired the son of Kozinski, a close friend, to serve as his clerk, even though the clerk, Clayton Kozinski, had not earned a spot on the Yale Law Journal, as almost all of Kavanaugh’s previous Yale clerks had.

The decision to hire Clayton Kozinski smacked of the kind of cronyism that is rife in federal courts. It was especially common for Kavanaugh, who not only had a reputation for hiring “model-like” female clerks, but also the children of powerful friends and allies.

Roberts, meanwhile, noted that the working group did not give the judiciary branch “a completely clean bill of health” and that it concluded that when misconduct happens it is “more likely to take the form of incivility or disrespect than overt sexual harassment” and “frequently goes unreported”.

Roberts noted that since the working group’s report was issued, changes to the judiciary’s code of conduct and disciplinary procedures have been proposed, including enlarging the definition of workplace misconduct. Other changes include lengthening the time that employees have to report misconduct.

The administrative office of the United States courts, which oversees the day-to-day operation of the federal courts, has also created an office of judicial integrity to monitor workplace conduct issues. Individual federal courts have also been studying their workplaces and adopting changes, and Roberts said the supreme court would also add to its existing policies and training programs.

The working group Roberts instituted will remain in place for the next year to monitor progress.

“The job is not finished until we have done all that we can to ensure that all of our employees are treated with fairness, dignity and respect,” Roberts wrote.
