The Judicial Ethics Forum (JEF)

This fairly recent research paper seeks ethics and disqualification reform in the Supreme Court:

The United States Supreme Court is the only court in the United States without a clearly defined ethics code. In the wake of the controversy over possible leaks from justices’ chambers following the decision in NFIB v. Sebelius, and in light of legislation recently introduced in Congress, this paper suggests two reforms for the Supreme Court. First, the time has finally come for the Court to adopt a comprehensive Code of Conduct. Second, the Court should alter its current recusal practice – in which decisions are made exclusively by individual justices – and instead resolve disqualification motions by a vote of the full court.
