Civil liberties are guarantees and freedoms that governments commit not to abridge, either by constitution, legislation, or judicial interpretation, without due process. Though the scope of the term differs between countries, civil liberties may include the freedom of conscience, freedom of press, freedom of religion, freedom of expression, freedom of assembly, the right to security and liberty, freedom of speech, the right to privacy, the right to equal treatment under the law and due process, the right to a fair trial, and the right to life. Other civil liberties include the right to own property, the right to defend oneself, and the right to bodily integrity. Within the distinctions between civil liberties and other types of liberty, distinctions exist between positive liberty/positive rights and negative liberty/negative rights. Overview Many contemporary nations have a constitution, a bill of rights, or similar constitutional documents that enumerate and seek to guarantee civil liberties. Other nations have enacted similar laws through a variety of legal means, including signing and ratifying or otherwise giving effect to key conventions such as the European Convention on Human Rights and the International Covenant on Civil and Political Rights.

In authoritarian regimes in which government censorship impedes on perceived civil liberties, some civil liberty advocates argue for the use of anonymity tools to allow for free speech, privacy, and anonymity. The degree to which democracies acknowledge civil liberties is affected by the influence of terrorism. Whether the existence of victimless crimes infringes upon civil liberties is also a matter of dispute. Another matter of debate is the suspension or alteration of certain civil liberties in times of war or state of emergency, including whether and to what extent this should occur. The formal concept of civil liberties is often dated back to Magna Carta, an English legal charter agreed in 1215 which in turn was based on pre-existing documents, namely the Charter of Liberties. Asia China The Constitution of the People's Republic of China (which applies only to mainland China, not to Hong Kong, Macau, and Taiwan) especially its Fundamental Rights and Duties of Citizens, claims to protect many civil liberties. Taiwan, which is separated from Mainland China, has its own Constitution. Although the 1982 constitution guarantees civil liberties,
