Apparently there is no standard and no disciplinary process, but there could be. The issue has been passed back to Chief Justice Roberts. He could take action to ensure that the court itself sets up ethics standards and a review process similar to what the Judicial Council does for lower courts. Of course, the Supreme Court would be reviewing itself. But apparently the court currently does even have standards, much less a review process.The ethics question goes beyond the complaints against Kavanaugh. Some justices have made speeches that appear to compromise their objectivity. Each justice seems to be able to decide what is and is not ethical for themselves. This is a chance for the court to set up standards that apply to all of them. Even self-policing standards would be better than no standards, and would serve as a baseline for considering impeachment.If the court fails to set up ethics standards, Congress could and should do so. Roberts talks a lot about maintaining the objectivity of the court, but so far he has done nothing but talk. If Congress set up ethics standards for Supreme Court justices (it would be easy to copy and modify existing standards for lower courts) there would still be major questions about enforcing them because of separation of powers. Nevertheless Congress should start to take action. Maybe this would spur the court to head off congressional standards by setting their own standards.Unfortunately the current split government makes it difficult for Congress to move forward on this or any other issue. It is a difficult situation, but the current lack of standards is becoming untenable. Roberts needs to stop talking and take action.
