The Ninth Amendment to the United States Constitution, ratified in 1791, states that the enumeration of certain rights in the Constitution does not mean that other rights not listed are not protected. This amendment emphasizes that individuals have more rights than those explicitly mentioned in the Constitution, ensuring that unenumerated rights are still recognized. The purpose of the Ninth Amendment is to prevent the government from claiming that the only rights people have are those specifically outlined in the Constitution. It serves as a reminder that personal liberties extend beyond the written text, safeguarding individual freedoms and promoting a broader interpretation of rights.
