The recent scandal involving Justice Clarence Thomas accepting lavish gifts from Dallas billionaire Harlan Crow has reignited the debate over whether Supreme Court justices should be subject to a public code of conduct. While lower federal judges are bound by a code of ethics, the Supreme Court has long resisted adopting one. Justice Thomas has accepted private jet rides, free vacations, and other gifts from Crow over many years without disclosing them as required by law. The issue is not the friendship between the two men, but the potential for impropriety and harm to the Court’s credibility. The lack of a public code of ethics makes it possible for judges to operate in secrecy, and it puts the entire supreme court at risk. The Supreme Court should adopt a code of conduct that is transparent and that is enforced by either the court itself or an external body. The code should be explicit about what is allowed and what isn't, modeling the highest standards of ethical behavior worthy of the highest court of the land. The goal should be to ensure that the Court and its members avoid any appearance of impropriety and maintain the trust of the American people.
