Amendment X

Partial

Powers Reserved to the States and the People

Ratified December 15, 1791

The Tenth Amendment is the constitutional anchor of federalism. It was long treated as a truism with little independent force, but New York v. United States (1992) and Printz v. United States (1997) revitalized it as a genuine limit on federal commandeering of state governments and officers.
