The constitutional role of the monarch

The Crown sits at the formal apex of the British constitution and at the effective margin of it. Acts of Parliament are enacted ''by the Queen's most Excellent Majesty, by and with the advice and consent of the Lords Spiritual and Temporal, and Commons''; the courts are ''Her Majesty's''; the executive is ''Her Majesty's Government''; and the armed forces, the Civil Service, and the Crown Prosecution Service are all formally Crown bodies. Yet the personal autonomous power of the monarch — the capacity to refuse a Bill, to sack a Prime Minister, to dissolve Parliament against advice — is, for every practical purpose in the modern era, extinct.

This week explores the gap between formal and effective monarchy. It traces how seventeenth-century constitutional struggles produced the doctrines that empty the Crown of substantive content: that the personal prerogatives are exercised on ministerial advice, that ministers (not the sovereign) bear political responsibility, and that constitutional conventions — not legal rules — police the behaviour of the monarch.

The topic matters for three reasons. First, it forces students to think carefully about the distinction between legal and political constitutional rules — many of the most important norms governing the Crown are conventions, unenforceable in court but routinely observed. Secondly, it provides the cleanest test case for Bagehot's celebrated ''dignified versus efficient'' typology, and for the republican critique advanced by Adam Tomkins and others. Thirdly, it raises questions of the highest practical importance: who, if anyone, may refuse to dissolve Parliament; what the sovereign's role is in a hung parliament; and what (if any) reserve power survives the Fixed-term Parliaments Act 2011 and its replacement by the Dissolution and Calling of Parliament Act 2022.

The current settlement is the residue of two centuries of constitutional contest. The Stuart period brought open conflict over the legal limits of royal power — the Case of Proclamations (1611) 12 Co Rep 74 (Coke CJ: ''the King hath no prerogative, but that which the law of the land allows him''); the Petition of Right 1628; the Civil War; the regicide of 1649; the Restoration of 1660; and finally the Glorious Revolution of 1688–89, which ejected James II and seated William and Mary on terms set by the political nation.

The Bill of Rights 1689 is the foundational text. It declared illegal the suspending power, the dispensing power, and the levying of money without parliamentary consent; secured freedom of speech in Parliament; and required regular parliaments. The Act of Settlement 1701 added the security of judicial tenure (''quamdiu se bene gesserint'') and Protestant succession. Together these statutes converted the monarchy from one whose authority rested on divine-right theory and inherited prerogative into one constituted by, and subordinate to, statute.

The nineteenth century saw the political prerogatives migrate to ministers. The defeat of George III's intervention against the Coalition in 1783–84, the resignation of William IV's last attempt to choose a Prime Minister against the Commons majority in 1834, and the accession of Victoria — who came to accept (with prompting from Albert and Stockmar) that her role was to advise, encourage, and warn but not to govern — completed the process. By the time Bagehot wrote The English Constitution in 1867, the picture he painted was already settled: the Cabinet governed, the monarch reigned.

The twentieth century tested the residue. George V navigated the Lloyd George–Asquith reconstruction (1916), the Irish settlement (1921), the first minority Labour government (1924), and the National Government crisis of 1931. Each episode left the same imprint: the sovereign's role is to recognise the political fact of who can command the Commons and to act on advice. The post-war period removed nearly all remaining substantive choice points — the dissolution prerogative was put to sleep by the FTPA 2011 and partially reawakened by the Dissolution and Calling of Parliament Act 2022, while honours, judicial appointments, and most Crown patronage have been progressively detached from royal initiative.

The constitutional role of the monarch is defined by three interlocking principles, each developed by convention rather than statute, and each the product of the long retreat from personal rule that this week traces.

(1) The sovereign acts on advice. The orthodox formulation is that of Sir Ivor Jennings: ''the Sovereign acts on the advice of the responsible Ministers, and the responsibility for those acts rests on the Ministers and not on the Sovereign'' (Jennings, Cabinet Government, 3rd edn (CUP 1959) 339). The advice is constitutionally binding on the sovereign in the sense that refusal to follow it would precipitate a constitutional crisis: ministers would resign (or, if they would not, would have to be dismissed and replaced by ministers who would advise differently — a step the modern monarch cannot realistically take).

Five graded practice questions are listed in the Practice Questions panel below this note. Two foundation questions test recall and application of the personal prerogatives; two standard questions test analytical engagement with Miller II and the 2022 Act; one challenge question requires comparative argument and engagement with Tomkins and Twomey.
