Parliamentary Sovereignty
The orthodox view
- The orthodox view is that Parliament is legally ‘sovereign’.
What does Parliamentary Sovereignty mean?
- Parliamentary sovereignty means that Parliament has sovereign law-making supreme powers.
- Parliament can pass, amend or repeal any primary legislation in the UK.
Historical Development of Parliamentary Sovereignty
Post 1688
- The Bill of Rights 1688 is a political source of parliamentary sovereignty. The Crown took the thrown accepting that Parliament was sovereign. This was a political contract between the Crown and Parliament.
A.V. Dicey’s orthodox theory of Parliamentary Sovereignty
- Parliament can make or unmake any law on any subject matter. The courts must obey this.
- No Parliament is bound by its predecessors or can bind its successors.
- No body, including a court of law, can question the validity of an Act of Parliament.
Model 1: Wade and Continuing Sovereignty
Parliament is fully sovereign, sovereignty is fixed (or ‘continuing’), it is impossible for Parliament to do anything that would limit its own powers.
Continuing vs self-embracing sovereignty
- Wade argues the UK has a continuing sovereignty, which cannot be destroyed and therefore, cannot entrench legislation.
Model 2: Self-embracing sovereignty
The self-embracing model agrees with A.V Dicey’s theory that Parliament is sovereign. However, it disagrees with the fact that entrenchment is not possible.
The proponents of the new view
- The proponents of the new view argue that entrenchment is possible.
- Their central argument is that Parliament is and should be capable of laying binding conditions on how and what form legislation is to be enacted.
Model 3: EU law is a substantive limit on Parliament’s law-making authority
- This model rejects the first model as it characterises parliamentary sovereignty as a legal phenomenon.
