Mandatory recusal by U.S. Supreme Court Judges on any case with conflicts of interest. This is already the law everywhere else, but for some reason does not apply to judges/attorneys serving in the U.S. Supreme Court. This would prevent judges who were previously attorneys for corporations to vote on cases involving those corporations. i.e. Clarence Thomas used to work for Monsanto, yet he still votes on all of Monsanto's cases (and always sides with them).
