What does the 10th Amendment reserve?

The 10th Amendment to the United States Constitution reserves powers that are not specifically delegated to the federal government by the Constitution, nor prohibited to the states, to the states themselves or to the people. This amendment underscores the principle of federalism, which is a foundational concept in American governance that establishes a division of responsibilities and powers between the national and state governments.

The significance of the 10th Amendment lies in its affirmation of state sovereignty and the rights of the individual. It serves as a constitutional guarantee that any power not explicitly granted to the federal government remains with the states or the people, allowing for a diverse array of laws and governance structures based on local needs and values. This framework encourages states to legislate and make decisions that reflect their unique circumstances without overreach from federal authority.
