I don't think that even Judge Scalia could get behind the notion of the Signing Statement,if he really is the Strict Constructionist he claims to be.

Bush's concept of the signing statement is the whisky-soaked-weekend bastard offspring of the Congressional introductory statement, which the Courts have used for centuries in determining the Legislative intent of a Law under review. It's a favorite tool of the Strict Constructionist crowd.

Hearings might be useful in an impeachment context, but that ain't never gonna happen. A more effective technique would be a lawsuit directly chalanging the practice.
