The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people.
Because the Tenth Amendment concerns the relationship between the federal government’s powers and those powers reserved to the states, it is sometimes invoked—implicitly or explicitly—in cases exploring the limits of Congress’s various enumerated powers.1 These decisions are primarily addressed elsewhere in the Constitution Annotated under the particular enumerated federal power at issue.2
The key issue in Tenth Amendment doctrine, as such, is whether the Amendment imposes affirmative limitations on federal power beyond the limits inherent in the various enumerated powers themselves. In other words, assuming that an enumerated power supports congressional action in a particular area, may the Tenth Amendment (or the federalism principles it confirms3 ) nonetheless render the legislation beyond federal power? And, if so, what are the contours of the limitations that the Tenth Amendment imposes?
The Supreme Court’s jurisprudence on these questions has not followed a straight line.4 At times, the Court has stated that the Tenth Amendment lacks substantive constitutional content and “does not operate as a limitation upon the powers, express or implied, delegated to the national government.” 5 At other times, the Court has found affirmative federalism limitations in the Amendment, invalidating federal statutes “not because Congress lacked legislative authority over the subject matter, but because those statutes violated the principles of federalism contained in the Tenth Amendment.” 6
The Supreme Court’s Tenth Amendment jurisprudence has gone through several cycles over its history. In the 19th century, Chief Justice John Marshall’s landmark opinion in McCulloch v. Maryland rejected the notion that the Tenth Amendment denied implied or incidental powers to the federal government, adopting an approach to assessing congressional power focused not on the Tenth Amendment itself, but the larger constitutional context.7
In the early 20th century, the Court relied on the Tenth Amendment to strike down various economic regulations as invasive of the police power reserved to the states by the Amendment.8 Beginning in the late 1930s, many of these decisions were overruled or limited as the Court embraced a broader conception of Congress’s Commerce Clause power, along with the view that the Tenth Amendment does not bar federal action that is necessary and proper to the exercise of federal power.9
Tenth Amendment doctrine then laid largely dormant until the mid-1970s. In National League of Cities v Usery, the Court relied on the Amendment to hold that Congress may not use its commerce power to “directly displace the States’ freedom to structure integral operations in areas of traditional governmental functions.” 10 Less than a decade later in Garcia v. San Antonio Metropolitan Transit Authority, however, the Court overruled National League of Cities as “unworkable” and “inconsistent with established principles of federalism,” 11 while implying that the Tenth Amendment lacked any judicially enforceable protections for state sovereignty.12
In the 1990s, the Court changed course again, holding in New York v. United States that the Tenth Amendment prohibits Congress from “commandeering” the states—that is, directly compelling them to enact or enforce a federal regulatory program.13 The resulting “anti-commandeering” doctrine has been the subject of a line of Supreme Court cases continuing to the present.14
