I'll believe it when I see it:

"We will submit legislation to the United States Senate which will...authorize the Congress to undertake judicial review of those signing statements with the view to having the president's acts declared unconstitutional," Judiciary Committee Chairman Arlen Specter, R-Pa., said on the Senate floor.--Specter's announcement came the same day that an American Bar Association task force concluded that by attaching conditions to legislation, the president has sidestepped his constitutional duty to either sign a bill, veto it, or take no action.
