Collectively Britain's overseas territories encompass an approximate land area of , with a total population of approximately 250,000. The overseas territories also give the UK the world's fifth largest exclusive economic zone at . A 1999 UK government white paper stated that: "[The] Overseas Territories are British for as long as they wish to remain British. Britain has willingly granted independence where it has been requested; and we will continue to do so where this is an option." Self-determination is also enshrined in the constitutions of several overseas territories and three have specifically voted to remain under British sovereignty (Bermuda in 1995, Gibraltar in 2002 and the Falkland Islands in 2013).

The power to pass legislation affecting the islands ultimately rests with their own respective legislative assemblies, with the assent of the Crown (Privy Council or, in the case of the Isle of Man, in certain circumstances the Lieutenant-Governor). Since 2005 each Crown dependency has had a Chief Minister as its head of government.

Both English law, which applies in England and Wales, and Northern Ireland law are based on common-law principles. The essence of common law is that, subject to statute, the law is developed by judges in
