In this reading of William Blackstone's Commentaries the jurist is neither a conservative promoter of arbitrary power nor a modern liberalizer of the common law. He is a proceduralist who emphasizes due process of law as the way to reconcile political liberty with parliamentary sovereignty. Blackstone's jurisprudence reflects a particular reading of political history, one that sees Parliament at the forefront of the protection of English liberties. While the legislature is capable of tyranny, it is in the king and the courts that historically he finds the greatest examples of arbitrary rule. And it has been the exercise of parliamentary sovereignty that has reinstated and guarded due process—in particular, habeas corpus—thereby preserving and facilitating public liberty.
