Unalienable

adj. not able to be taken away, not alienable

The term inalienable rights (or unalienable rights) refers to a theoretical set of human rights that are fundamental, are not awarded by human power, and cannot be surrendered. They are by definition, rights retained by the people. Inalienable rights may be defined as natural rights or human rights, but natural rights are not required by definition to be inalienable.
