Rights
An uncodified constitution built on parliamentary sovereignty
There is no single constitutional document. Statutes, common law, conventions and devolution settlements together form the constitution, and Parliament remains legally supreme.
Key rules
- Courts may declare legislation incompatible with the Human Rights Act 1998 but cannot strike it down.
- Three devolved settlements distribute power to Scotland, Wales and Northern Ireland by reserved-matters lists.
- Royal prerogative powers are exercised by ministers and are reviewable by the courts.
Governing law
- Human Rights Act 1998Incorporates the ECHR into domestic law
- Constitutional Reform Act 2005Created the Supreme Court
- Scotland Act 1998
In practice
Miller (2017) and Miller II (2019) confirmed that even high-politics prerogative decisions are justiciable, making judicial review the central constitutional remedy.
