The Tenth Amendment clarifies the federal government's limited powers
The Tenth Amendment to the United States Constitution was proposed by the 1st United States Congress in 1789 during its first term following the adoption of the Constitution. It was ratified on December 15, 1791, and it clarifies the federal government's limited powers. The amendment states that any powers not specifically given to the federal government, nor withheld from the states, are reserved for the states or the people. In other words, the federal government only has the powers delegated to it by the Constitution. This amendment was designed to address the concerns of Anti-Federalists, who opposed the creation of a stronger federal government.
The Tenth Amendment has been interpreted as a clarification of the federal government's limited powers and has been invoked in several Supreme Court decisions to determine if the federal government has overstepped its authority. For example, in United States v. Lopez (1995), the Supreme Court ruled that a federal law mandating a "gun-free zone" on and around public school campuses was unconstitutional because there was no clause in the Constitution authorizing it. This ruling limited the federal government's authority to enact policies through the Commerce Clause.
The Tenth Amendment also played a role in Gonzales v. Raich (2005), where a California woman sued the Drug Enforcement Administration after her medical cannabis crop was seized by federal agents. Although medical cannabis was legal under California state law, it was prohibited at the federal level. The Supreme Court upheld the federal government's action, stating that growing one's own cannabis affects the interstate market for cannabis.
The amendment has been considered by some legal scholars as a tautology or a statement affirming that the federal government does not have any rights that it has not been given. However, others view it as a necessary clarification of the relationship between the national and state governments, ensuring that the federal government cannot exercise powers not granted to it by the Constitution.

It addresses the relationship between national and state governments
The Tenth Amendment to the United States Constitution was proposed by the 1st United States Congress in 1789, during its first term following the adoption of the Constitution. It was ratified on December 15, 1791, and it addresses the relationship between national and state governments.
The Tenth Amendment states that the Federal Government only has those powers delegated to it in the Constitution. It clarifies that any powers not specifically given to the federal government, nor withheld from the states, are reserved for those respective states or the people at large. This means that the federal government is limited to the powers granted in the Constitution, and it cannot infringe on the liberties of the people. The amendment was designed to ensure that the federal government had limited, enumerated powers, and to allay fears that the new national government might seek to exercise powers not granted to it.
The Tenth Amendment has been invoked in several Supreme Court decisions to determine if the federal government operated within or overstepped its bounds of authority. For example, in United States v. Lopez (1995), a federal law mandating a "gun-free zone" on and around public school campuses was struck down. The Supreme Court ruled that there was no clause in the Constitution authorizing the federal law, and this limited the federal government's authority to enact policies through the Commerce Clause.
The Tenth Amendment also played a role in Gonzales v. Raich (2005), where a California woman sued the Drug Enforcement Administration after her medical cannabis crop was seized and destroyed by federal agents. Although medical cannabis was legal under California state law, it was prohibited at the federal level. The Supreme Court stated that growing one's own cannabis affects the interstate market, and the federal government's authority to regulate interstate commerce superseded the state law in this case.

The amendment was proposed by Thomas Burke

Burke wanted to ensure that there was no ambiguity concerning the differences in state and federal power. The amendment was designed to reaffirm the principles of federalism and reinforce the notion of the Federal Government maintaining only limited, enumerated powers.
The Tenth Amendment states:
> 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.
In essence, the amendment clarifies the relationship between the national and state governments. It confirms that the federal government is a limited government with only the powers granted in the Constitution. This was particularly important to Anti-Federalists, who opposed the creation of a stronger federal government.
The Tenth Amendment has been described as a truism or a tautology, stating a self-evident truth. It was proposed to allay fears that the new national government might seek to exercise powers not granted and to ensure that the states could fully exercise their reserved powers. The amendment was passed by the Continental Congress, and the states ratified it in 1791 as part of the Bill of Rights.

The Tenth Amendment has been invoked in several Supreme Court decisions
The Tenth Amendment of the United States Constitution was proposed by the 1st United States Congress in 1789 during its first term following the adoption of the Constitution. It was passed to reaffirm the principles of federalism and reinforce the notion that the Federal Government maintains only limited, enumerated powers. The amendment states:
> 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.
In United States v. Lopez (1995), the Supreme Court ruled against a federal law mandating a "gun-free zone" on and around public school campuses, stating that there was no clause in the Constitution authorizing the federal law. This decision limited the government's power under the Commerce Clause and was the first modern Supreme Court opinion to do so.
In Printz v. United States (1997), the Supreme Court reaffirmed states' rights and the Constitution's anti-commandeering provisions. The Court struck down part of the Brady Handgun Violence Prevention Act, which required local sheriffs to perform gun background checks, as it conflicted with the concept of "anti-commandeering" set out in an earlier case, New York v. United States (1992).
In Gonzales v. Raich (2005), a California woman sued the Drug Enforcement Administration after her medical cannabis crop, legal under California state law, was seized by federal agents due to federal prohibition. The Supreme Court ruled that growing one's own cannabis affects the interstate market, demonstrating the continued complexity of federal and state power dynamics.
