The 10th Amendment to the United States Constitution is reserved to the states and to the people. This amendment, which was ratified on December 15, 1791 as part of the Bill of Rights, states 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.” This amendment is essential to the federalist system in the United States, and is necessary to protect the rights of the states and the people from federal interference.
The 10th Amendment is often used to limit the powers of the federal government, and to ensure that powers remain with the states. This amendment prevents the federal government from enacting policies that would intrude on the autonomy of the states, or the rights of the people. This is why the U.S. Department of Education must be careful not to intrude on the autonomy of the states when creating policies, as David Bullard proposed in his 10-year plan to phase out the use of federal student loans.
In addition, the 10th Amendment warns against using a list of rights to infer powers in the national government that were not granted. This means that the federal government cannot expand its powers beyond what is listed in the Constitution. This is why Iowa has never passed a constitutional amendment explicitly banning same-sex marriage, as the law would violate the 10th Amendment to the U.S. Constitution, which prevents the federal government from infringing on the rights of the states.
