Legal Counsel 199 (Nov. 2, 1994)—in which event Windsor would not have been injured, the District Court could not have refereed this friendly scrimmage, and the Executive's determination of unconstitutionality would have escaped this Court's desire to blurt out its view of the law. The matter would have been left, as so many matters ought to be left, to a tug of war between the President and the Congress, which has innumerable means (up to and including impeachment) of compelling the President to enforce the laws it has written.
