[I]mpeachment does not require proof of a crime... The argument that only criminal offenses are impeachable is deeply and profoundly wrong. It misunderstands the Constitution, U.S. history, and the nature of criminal law in important ways.

American Constitutional Law... final chapter... "The Problem of State Action," grappled with one of the most perplexing aspects in the law of the U.S. Constitution: its character as a body of law addressing not ordinary private conduct but only government conduct. ...[T]he law of the Constitution is a kind of meta-law. ...many instances of what might be regarded as government inaction pose troubling constitutional questions. ...[T]he Supreme Court has generally interpreted constitutional provisions as having nothing at all to say about non-governmental choices. ...One might ...say that the constitutional principle limiting the Constitution’s reach to "state action" is an unwritten command ...essentially "heard" in the sounds of constitutional silence. ...I closed the book with the question: "[I]s it not fitting that a book about the Constitution should close by studying what the Constitution is not about?"

[M]ost of us would readily concede that the framers of the 1787 Constitution adopted a federal system of government organization in order to, among other goals, help secure the institution of private property. When Madison, in his theory of faction, suggested that shifting the legislative responsibility for certain problems from the state to the national level could help assure that majorities would not trample on minority rights, the problems he had in mind were largely economic; the minority rights... were, for the most part, rights of property and contract.
