Constitution of the United Kingdom

The Constitution of the United Kingdom is uncodified: no single document contains it, so it can be changed by ordinary Act of Parliament with no provision formally entrenched. It is drawn instead from historical documents including Magna Carta of 1215, the Bill of Rights of 1689 and the Treaty of Union of 1706, from Acts of Parliament such as the Scotland Act 1998 and the Human Rights Act 1998, from court decisions recognizing constitutional principles, and from unwritten conventions governing political conduct. The Supreme Court recognizes parliamentary sovereignty, the rule of law, democracy and internationalism as its core constitutional principles, tracing parliamentary sovereignty to the Glorious Revolution of 1688 and universal suffrage to 1928.
