Law Tutor - The Doctrine of Parliamentary Sovereignty is a fundamental principle of the UK constitution. It means that Parliament has the supreme legal authority to make, amend, or repeal any law, and no other body, including the courts, can override or challenge its legislation. This doctrine ensures that Parliament’s decisions are final and absolute. However, it is subject to some practical limitations, such as political constraints and EU law influences (before Brexit). Established by constitutional scholars like A.V. Dicey, parliamentary sovereignty underpins the UK’s uncodified constitution, maintaining the legislature's dominance in the legal system.
