Does the Tenth Amendment let states limit rights people still have?

The Tenth Amendment is about powers not delegated to the federal government. It does not give states permission to disregard other constitutional limits. A state law can be invalid if it conflicts with a federal constitutional right, but states generally have room to legislate where no such limit applies.

The Bill of Rights originally restricted the federal government. Through the Fourteenth Amendment, courts have applied most of its protections to the states as well. State constitutions can also provide protections of their own.

The Ninth Amendment says that listing certain rights should not be read to deny or disparage other rights retained by the people. It does not spell out a complete list of those rights or, by itself, settle which restrictions are unconstitutional.

In Griswold v. Connecticut, the Court recognized a constitutional protection for marital privacy. Justice Goldberg’s concurrence discussed the Ninth Amendment, while the Court’s reasoning also drew on protections associated with other amendments and the Fourteenth Amendment. The case is an example of judicial interpretation, not a blanket rule that every claimed unlisted freedom defeats state legislation.

One distinction helps: the Supremacy Clause makes the Constitution and valid federal laws supreme over conflicting state law. It does not mean every state law has to carry out federal powers. State laws can stand unless they conflict with a controlling federal rule or violate a limit in the federal or state constitution.

Judges decide particular disputes by interpreting those rules. Their decisions can be contested and may change as cases develop, but the Tenth Amendment alone does not answer every question about an unlisted right.
