What an idiot. The Supreme Court is our living code of ethics. America's founded upon a moral theory, expressed prosaically and rhetorically in our Declaration. The Constitution is the legal expression of that moral theory, version two (version one didn't work and the Constitution is the embodiment of the founders' understanding of both our moral theory and plus the lessons learned from version one). The Supreme Court has, in the Constitution, the power to review laws that the Legislative Branch makes, and because laws are judged according to the Constitution, and because the Constitution is a legal expression of a moral theory, the Supreme Court is our living code of ethics. In judging their constitutionality the Court also judges the morality of our nation's laws. If Washington made a code of ethics for the Supreme Court, the Supreme Court is going to have the power to review that law, to see if it comports with the Constitution, and that is what we literally pay these guys and gals to already be doing. The only way you can correct a problem in the Supreme Court is with impeachment, and nobody's saying impeachment because we all know how ridiculous impeaching Justice Thomas over this is.
