The WSJ has an excerpt from a lecture by Supreme Court Justice Clarence which concludes:
….As important as our Constitution is, there is no one accepted way of interpreting it. Indeed, for some commentators, it seems that if they like or prefer a particular policy or conduct, then it must be constitutional; while the policies that they do not prefer or like are unconstitutional. Obviously, this approach cannot be right. But, it certainly is at the center of the process of selecting judges. It goes something like this. If a judge does not think that abortion is best as a matter of policy or personal opinion, then the thought is that he or she will find it unconstitutional; while the judge who thinks it is good policy will find it constitutional. Those who think this way often seem to believe that since this is the way they themselves think, everyone must be doing the same thing. In this sense, legal realism morphs into legal cynicism. Certainly this is no way to run a railroad, not to mention interpret the Constitution. . . .
Let me put it this way; there are really only two ways to interpret the Constitution — try to discern as best we can what the framers intended or make it up. No matter how ingenious, imaginative or artfully put, unless interpretive methodologies are tied to the original intent of the framers, they have no more basis in the Constitution than the latest football scores. To be sure, even the most conscientious effort to adhere to the original intent of the framers of our Constitution is flawed, as all methodologies and human institutions are; but at least originalism has the advantage of being legitimate and, I might add, impartial.
