What is considered the basis for English constitutional liberties?

The basis for English constitutional liberties is primarily rooted in historical documents like the Magna Carta of 1215, which established the principle of the rule of law and limited the power of the monarchy. Other key influences include the Bill of Rights of 1689, which outlined individual rights and parliamentary sovereignty, and the development of common law. Together, these elements have shaped the evolution of personal freedoms and legal protections in England.
