Civil liberties in the United States are certain inalienable rights retained by (as opposed to privileges granted to) citizens of the United States under the Constitution of the United States, as interpreted and clarified by the Supreme Court of the United States and lower federal courts.Civil liberties are simply defined as individual legal and constitutional protections from entities more powerful than an individual, for example, parts of the government, other individuals, or corporations. The liberties explicitly defined, make up the Bill of Rights, including freedom of speech, the right to bear arms, and the right to privacy. There are also many liberties of people not defined in the Constitution, as stated in the Ninth Amendment: The enumeration in the Constitution, of certain rights, shall not be construed to deny or disparage others retained by the people.
The extent of civil liberties and the periphery of the population of the United States who had access to these liberties has expanded over time. For example, the Constitution did not originally define who was eligible to vote, allowing each state to determine who was eligible. In the early history of the U.S., most states allowed only white male adult property owners to vote (about 6% of the population). The 'Three-Fifths Compromise' allowed the southern slaveholders to consolidate power and maintain slavery in America for eighty years after the ratification of the Constitution. And the Bill of Rights had little impact on judgements by the courts for the first 130 years after ratification.
Freedom of speech is a civil liberty protected under the First Amendment to the United States Constitution, adopted on December 15, 1791.
This civil liberty grants all United States citizens the right to express themselves and enjoy the expression of others without interference of the government. This freedom of expression is often tested and can be the center of controversy because of how it is interpreted. The courts have recognized the Bill of Rights as having the intention of rights of privacy and the separation of church and state, even though it is not clearly stated. It is also thought that the amendment refers only to government interference, which leads to individual corporations and businesses violating these freedoms.
