Tightening ethics rules for the Supreme Court has become a public policy concern due to recent revelations about Justice Clarence Thomas, who did not disclose extravagant gifts and financial arrangements with a billionaire Republican donor. However, the Supreme Court’s ethics rules are among the weakest in the federal government. Despite proposals in Congress to create a binding code of ethical conduct for the court, these proposals face political and constitutional obstacles. While the justices voluntarily follow financial disclosure rules established by the Judicial Conference, the rules are not constitutionally binding. Additionally, the code of ethical conduct for lower-court judges does not apply to Supreme Court justices. The court has no interest in adopting a binding code and Congress lacks the power to force one upon them. Any change in ethics rules for the court is seen as an attempt by liberals to delegitimize the court, according to Republicans. Efforts to tighten ethics rules for the Supreme Court face political polarization and constitutional limitations. The best solution would be for the court itself to adopt stronger ethics rules but it remains unclear how these rules would be enforced.
