Constitutional law in the United States is, for most practical purposes, the product of ‘judicial review’, the power of judges to disallow policy choices made by other officials or institutions of government, ostensibly because those choices are prohibited by the Constitution. This extraordinary and unprecedented power, America's dubious contribution to the science of government, has made American judges the most powerful in the world, not only legislators but super-legislators, legislators with virtually the last word. Because lawmaking power divorced from popular will is tyranny, most states have attempted to reconcile the lawmaking power of judges with representative self-government by subjecting all or some judges to some form of popular election. In all but four such states, judges, encouraged and supported by their fellow lawyers in the organized bar—would-be judges and beneficiaries of judicial power—have responded by adopting codes of judicial ethics that limit what candidates for election to judicial office are permitted to say. The effect is to undermine elections as a control on judicial power by limiting criticism of judicial activism, the misuse of judicial power.
