Joe Biden will announce plans to reform the US supreme court on Monday, Politico reported, citing two people familiar with the matter, adding that the US president was likely to back term limits for justices and an enforceable code of ethics. Biden said earlier this week during an Oval Office address that he would call for reform of the court. He is also expected to seek a constitutional amendment to limit immunity for presidents and some other officeholders, Politico reported, in the aftermath of a July supreme court ruling that presidents have broad immunity from prosecution. Biden will make the announcement in Texas on Monday and the specific proposals could change, the report added. Justice Elena Kagan on Thursday became the first member of the supreme court to call publicly for beefing up its new ethics code by adding a way to enforce it. “The thing that can be criticized is, you know, rules usually have enforcement mechanisms attached to them, and this one – this set of rules – does not,” Kagan said at an annual judicial conference held by the ninth circuit. More than 150 judges, attorneys, court personnel and others attended. The court had been considering adopting an ethics code for several years, but the effort took on added urgency after it was reported last year that Justice Clarence Thomas did not disclose luxury trips he accepted from a major Republican donor. Public confidence in the court has slipped sharply in recent years. In June, a survey for the Associated Press-Norc Center for Public Affairs Research found that four in 10 US adults have hardly any confidence in the justices and 70% believe they are more likely to be guided by their own ideology rather than serving as neutral arbiters.
