Which amendment states that rights not enumerated in the Constitution shall not be denied?

The Ninth Amendment to the United States Constitution explicitly states that the enumeration of certain rights in the Constitution does not mean that others do not exist. This amendment emphasizes the principle that the rights of the people are not limited to just those listed in the Constitution. Its purpose is to ensure that individuals have rights that may not be specifically mentioned, protecting them from being diminished or denied simply because they are not enumerated.

In the context of the other amendments listed: the Tenth Amendment addresses the powers reserved to the states and the people, the Eleventh Amendment deals with state immunity from certain lawsuits, and the Eighth Amendment prohibits excessive bail, fines, and cruel and unusual punishments. None of these amendments directly relates to the rights of individuals that are not explicitly stated in the Constitution, which is the focus of the Ninth Amendment.
