Tenth Amendment

"Legal Lexicon":
TENTH AMENDMENT - The Tenth Amendment provides that " 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. " U.S. Const. amend. X. As a textual matter, therefore, the Tenth Amendment "states but a truism that all is retained which has not been surrendered." United States v. Darby, 312 U.S. 100, 124 (1941). By its terms, the Amendment does not purport to limit the commerce power or any other enumerated power of Congress.
In recent years, however, the Tenth Amendment has been interpreted "to encompass any implied constitutional limitation on Congress' authority to regulate state activities, whether grounded in the Tenth Amendment itself or in principles of federalism derived generally from the Constitution." South Carolina v. Baker, 485 U.S. 505, 511 n.5 (1988). Thus, "the Tenth Amendment confirms that the power of the Federal Government is subject to limits that may, in a given instance, reserve power to the States." New York v. United States, 505 U.S. 144, 157 (1992).
There are numbers of ways in which the federal government is permitted to secure the assistance of state authorities in achieving federal legislative goals. First and most directly, the federal government may coerce the states and their employees into complying with federal laws of general applicability. Garcia v. San Antonio Metropolitan Transit Authority, 469 U.S. 528 (1985). Second, Congress may condition the grant of federal funds on the States' taking governmental action desired by Congress. South Dakota v. Dole, 483 U.S. 203 (1987).
State judicial and administrative bodies may be required to apply federal law. Testa v. Katt, 330 U.S. 386 (1947); FERC v. Mississippi, 456 U.S. 742, 760-61 (1982). The federal government may offer to preempt regulation in a given area, and permit the states to avoid preemption if they regulate in a manner acceptable to Congress. Hodel v. Virginia Surface Mining & Reclamation Ass'n, 452 U.S. 264, 290-91 (1981).
The federal government has been permitted effectively to compel the states to issue registered rather than bearer bonds. South Carolina v. Baker, 485 U.S. 505, 514 (1988). Finally, the federal government has been permitted to require state utility regulators to consider prescribed federal standards in determining regulatory policies. FERC v. Mississippi, 456 U.S. at 765. In the course of the latter ruling, the Supreme Court referred to and rejected the "19th century view" that "Congress has no power to impose on a State officer, as such, any duty whatever, and compel him to perform it." Id. at 761 (quoting Kentucky v. Dennison, 24 How. 66, 107 (1861)). That view, said the Court, "is not representative of the law today." Id. "The federal government has some power to enlist a branch of state government . . . to further federal ends." Id. at 762.
United States v. New York, 505 U.S. 144 (1992), "a direct order to regulate, standing alone, would . . . be beyond the power of Congress." Id. at 176. the Court in New York stated: "whether or not a particularly strong federal interest enables Congress to bring state governments within the orbit of generally applicable federal regulation, no Member of the Court has ever suggested that such a federal interest would enable Congress to command a state government to enact state regulation." Id. at 178. In the same vein was the Court's conclusion after reviewing the debates at the time of the founding of the Constitution:
