Welcome back to our "Crunching Concepts" series, where we aim to clarify essential legal concepts using simplified summaries generated by CaseSnappy. In this instalment, we explore the critical principle of parliamentary sovereignty, a central tenet of the UK constitution that establishes Parliament's supremacy in the legal system.
What is Parliamentary Sovereignty?
Parliamentary sovereignty is the principle that asserts the supremacy of the UK Parliament over other branches of government, including the executive and judiciary, as well as the legal system itself. Parliament, consisting of the House of Commons and the House of Lords, has the ultimate authority to make, amend, or repeal any law, with no other institution able to challenge or override its decisions.
Why is Parliamentary Sovereignty Important?
The importance of parliamentary sovereignty lies in the following:
1. It underpins the democratic legitimacy of the UK legal system, ensuring that elected representatives in Parliament are the ultimate decision-makers in creating or changing laws governing the country.
2. Parliamentary sovereignty provides legal certainty, as there can be no confusion or doubt regarding the ultimate source of authority for any legal rule in the UK.
3. It enables necessary legal changes to be made promptly and effectively either in response to societal developments or to address pressing issues.
Highlighting Parliamentary Sovereignty Through Example Cases
Understanding parliamentary sovereignty is best illustrated through relevant case law:
• R (Jackson) v Attorney General  UKHL 56 - This case concerned the validity of the Hunting Act 2004 and its potential impact on the principle of Parliamentary sovereignty.
• AXA General Insurance Ltd v HM Advocate  UKSC 46 - The Supreme Court held that courts could review acts of the Scottish Parliament for compatibility with common law. However, they also recognized its competence and supremacy in its legislative capacity.
• R (Miller) v Secretary of State for Exiting the European Union  UKSC 5 - This case determined that the government could not trigger the UK's exit from the European Union (EU) without parliamentary authorization, demonstrating that parliamentary sovereignty is retained when dealing with international agreements and treaties.
