Parliamentary sovereignty is a principle of the UK constitution. It makes Parliament the supreme legal authority in the UK which can create or end any law. Generally, the courts cannot overrule its legislation and no Parliament can pass laws that future Parliaments cannot change.
The concept of parliamentary sovereignty was central to the English Civil War: Royalists argued that power held by the King, and delegated to Parliament, challenged by the Parliamentarians. The issue of taxation was a significant power struggle between Parliament and the King during the Stuart period.
