Petition of Right, a statute of the English Parliament passed in 1628 and accepted by Charles I. This petition stated several fundamental principles of the English constitution. It ranks in importance with Magna Charta (1215) and the Bill of Rights (1689). It was largely drafted by Sir Edward Coke, former lord chancellor.

Parliament passed the petition as a reaction against the arbitrary rule of King Charles. The petition restated some of the ancient rights and privileges of Englishmen, and reaffirmed four great principles: no taxes should be levied without the consent of Parliament; no freeman should be imprisoned except by the law of the land; no soldiers should be billeted in citizens' homes without payment; and martial law should not be proclaimed in time of peace. Charles accepted the petition to get the taxes he wanted, but he continued his arbitrary rule. Eventually he was defeated in the Civil War and was put to death.
