United States v. Butler
United States v. Butler (1936) declared that the Agricultural Adjustment Act of 1933 was unconstitutional.
It is notable that Butler is regarded as "the last case in which this Court struck down an Act of Congress as beyond the authority granted by the Spending Clause."
The case affirmed the powers of the Tenth Amendment, declaring:
From the accepted doctrine that the United States is a government of delegated powers, it follows that those not expressly granted, or reasonably to be implied from such as are conferred, are reserved to the states, or to the people. To forestall any suggestion to the contrary, the Tenth Amendment was adopted. The same proposition, otherwise stated, is that powers not granted are prohibited. None to regulate agricultural production is given, and therefore legislation by Congress for that purpose is forbidden.
