In my last post, I looked at the influence of public choice on originalism, which I discuss in a recent paper. Here I suggest that originalism also faces challenges from public choice that it needs to address. Here are four of them:
How is Originalism Self-sustaining? Public choice originalism shows why one needs to enforce constitutional provisions according to their original meaning to prevent legislative or even popular majorities from undermining the supermajoritarian framework. But why will judges follow originalism, when the supermajoritarian framework of the Constitution makes it very difficult for people to overrule their decisions through a constitutional amendment? Recent work by rational choice political scientists has focused on the general question of how a constitution can be self-enforcing.
One possible answer is that justices will be disciplined by a culture of originalism. As Richard Posner notes, an important part of judicial satisfaction comes from feeling that they have played the game by the rules. If the rules are understood to be originalist, that understanding provides substantial discipline. One observation about this solution is that it makes the success of originalism ultimately dependent on cultural capital–in this case that of the legal culture. That fact is not necessarily surprising. Many other important social institutions, like the market economy itself, have been thought dependent on culture.
