Which amendment ensures that the rights of the people cannot be restricted to those specifically mentioned in the Constitution?

The Ninth Amendment is crucial because it explicitly states that the enumeration of certain rights in the Constitution does not imply that individuals do not possess other rights that are not specifically mentioned. This amendment serves to protect the rights of the people by acknowledging that they have more rights than those listed in the Constitution, allowing for a broader interpretation of individual liberties. It ensures that the absence of specific rights from the listed amendments does not mean those rights are unrecognized or denied, reflecting the framers' intention to safeguard the various rights of individuals.

In contrast, the other amendments mentioned focus on more specific rights and judicial processes rather than the protection of unenumerated rights. Thus, the Ninth Amendment plays a pivotal role in supporting the notion that the list of rights in the Constitution is not exhaustive.
