An argument for why emergencies are no excuse for extralegal action by presidents Using emergency as a cause for action ultimately leads to an almost unnoticed evolution in the political understanding of presidential powers.

Thomas Crocker urges Congress, the courts, and other bodies to put those checks into practice.
