How about a civil liberty........

Civil Liberties are defined as, the rights to freedom of thought, expression, and action, and the protection of these rights from government interference or restriction. Civil liberties are the hallmark of liberal, democratic “free” societies. In the United States, the Bill of Rights guarantees a variety of civil liberties, most notably freedom of assembly, freedom of the press, freedom of religion, and freedom of speech, expressed in the First Amendment.

or

Fundamental individual rights, such as freedom of speech and religion, protected by law against unwarranted governmental or other interference.

or

Civil liberties is the name given to freedoms that completely protect the individual from government. Civil liberties set limits for government so that it can not abuse its power and interfere with the lives of its citizens.

and then from the Constitution:

We the people of the United States, in order to form a more perfect union, establish justice, insure domestic tranquility, provide for the common defense, promote the general welfare, and secure the blessings of liberty to ourselves and our posterity, do ordain and establish this Constitution for the United States of America.
