Every president to date has declared the War Powers Resolution to be unconstitutional, and the Supreme Court
has struck down the 'legislative veto' embodied in Section 5 of the Resolution in the case INS v. Chadha (1983). However,
in every instance since the act was passed, the President has requested and received authorization for the use of force (though
not a formal declaration of war) consistent with the provisions of the resolution. The reports to Congress required of the
President have been drafted to state that they are "consistent with" the War Powers Resolution rather than "pursuant to" so
as to take into account the Presidential position that the Resolution is unconsitutional.
The intended purpose of the act was to serve as a check on the power of the President to commit the United
States to military action by exercising the constitutional authority of Congress to declare war under Article One. Many constitutional
scholars have questioned the usefulness of the resolution, pointing out that Congress has tended to defer to the Executive
when conducting war.
