Editing Reserved powers (section)

=== United States ===
In the [[United States]], the [[Tenth Amendment to the United States Constitution|Tenth Amendment]] of the Constitution states that the powers not granted to the [[federal government of the United States|federal government]] are reserved to the states, unless prohibited to the states.<ref name="nerenberg" /><ref name="uslegal">{{citation|url=https://definitions.uslegal.com/r/reserved-power/|title=Reserved Power Law and Legal Definition|publisher=US Legal, Inc.|accessdate=August 8, 2018}}</ref> This amendment does not refer to powers “explicitly” or “expressly” granted to the federal government, and therefore the federal government possesses many [[implied powers]] that are not reserved to the states.<ref>Frank, Walter.

After [[World War II]], the [[Supreme Court of the United States|Supreme Court]] often ruled against parties challenging the powers of [[United States Congress|Congress]] per the Tenth Amendment, with exceptions during the [[Rehnquist Court]].<ref name=":0">{{Cite book|last=McAffee|first=Thomas B.|title=Powers reserved for the people and the states : a history of the Ninth and Tenth Amendments|date=2006|publisher=Praeger Publishers|others=Bybee, Jay S., Bryant, A.

National Collegiate Athletic Association]]'' (2018).

In the United States, many powers that are not reserved to the states are [[exclusive federal powers]], and thus states are forbidden to exercise them.  Alternatively, powers that are not reserved to the states may be [[concurrent powers]] that both the states and federal government can exercise at the same time (such as the power to enact taxes to raise revenue).<ref>''[https://books.google.com/books?id=MLhxnmmtivwC&pg=PA31 The Complete Idiot's Guide to U.S. Government and Politics]'', p. 31 (Penguin 2009).</ref>
