What do civil rights mean?
Civil and political rights
Civil and political rights are a class of rights that protect individuals' freedom from infringement by governments, social organizations, and private individuals. They ensure one's ability to participate in the civil and political life of the society and state without discrimination or repression.
Constitution
In practice democratic governments do not use the lack of entrenchment of the constitution to impose the will of the government or abolish all civil rights, as they could in theory do, but the distinction between constitutional and other law is still somewhat arbitrary, usually following historical principles embodied in important past legislation. For example, several British Acts of Parliament such as the Bill of Rights, Human Rights Act and, prior to the creation of Parliament, Magna Carta are regarded as granting fundamental rights and principles which are treated as almost constitutional. Several rights that in another state might be guaranteed by constitution have indeed been abolished or modified by the British parliament in the early 21st century, including the unconditional right to trial by jury, the right to silence without prejudicial inference, permissible detention before a charge is made extended from 24 hours to 42 days, and the right not to be tried twice for the same offence.
