U.S. Supreme Court Justice Elena Kagan has called for the addition of an enforcement mechanism to the court's new ethics code, which was established last November but lacks means of implementation. Kagan suggested that Chief Justice John Roberts could form a committee of respected lower-court judges to monitor compliance and address violations. She emphasized that while the current rules are good, they are insufficient without an enforcement mechanism. Kagan did not speak on behalf of the entire court and acknowledged the complexity of determining who should oversee justices' conduct. Her remarks come amid heightened scrutiny and criticism of the court's ethics, particularly involving Justices Samuel Alito and Clarence Thomas.
