A bill of rights, sometimes called a declaration of rights or a charter of rights, is a list of the most important rights to the citizens of a country. The purpose is to protect those rights against infringement from public officials and private citizens.[1]
Bills of rights may be entrenched or unentrenched. An entrenched bill of rights cannot be amended or repealed by a country's legislature through regular procedure, instead requiring a supermajority or referendum; often it is part of a country's constitution, and therefore subject to special procedures applicable to constitutional amendments.
