The Ninth Amendment to the United States Constitution was added to ensure the protection of individual rights that may not be specifically listed in the Constitution or Bill of Rights. It was meant to emphasize that the enumeration of certain rights in the Constitution shouldn't be construed as a limitation on other rights that the people may have. Essentially, it serves to protect individual liberties by acknowledging that there are inherent rights that are protected by the Constitution and the government cannot infringe upon them, even if they are not explicitly stated in the document.
