Legislature , the last monarch to arbitrarily dissolve Parliament by using the royal prerogative The power to dissolve parliament is "perhaps the most important residual prerogative exercised personally by the sovereign, and represents the greatest potential for controversy." This prerogative is normally exercised at the request of the
prime minister, either at his or her discretion or following a
motion of no confidence. Constitutional theorists have had differing views as to whether a unilateral dissolution of Parliament would be possible today;
Sir Ivor Jennings wrote that a dissolution involves "the acquiescence of ministers", and as such the monarch could not dissolve Parliament without ministerial consent; "if ministers refuse to give such advice, she can do no more than dismiss them." A. V. Dicey, however, believed that in certain extreme circumstances the monarch could dissolve Parliament single-handedly, on the condition that "an occasion has arisen on which there is fair reason to suppose that the opinion of the House is not the opinion of the electors ... A dissolution is allowable, or necessary, whenever the wishes of the legislature are, or may fairly be presumed to be, different from the wishes of the nation." The monarch could force the dissolution of Parliament through a refusal of
royal assent; this would very likely lead to a government resigning. By convention, the monarch always assents to bills; the last time the royal assent was not given was in 1708 during the reign of
Queen Anne when, on ministerial advice, she withheld royal assent from the
Scottish Militia Bill. This does not mean that the right to refuse, even contrary to the wishes of the Prime Minister, has died: the threat of the Royal Veto by
George III and
George IV made
Catholic Emancipation impossible between 1800 and 1829, whilst
George V had been privately advised (by his own lawyer, not by the Prime Minister) that he could veto the
Third Irish Home Rule Bill; Jennings writes that "it was assumed by the King throughout that he had not only the legal power but the constitutional right to refuse assent". The royal prerogative to dissolve Parliament was abrogated by Section 3(2) of the
Fixed-term Parliaments Act 2011, and revived by the
Dissolution and Calling of Parliament Act 2022, which repealed the 2011 Act. Section 6(1) of the 2011 Act however specifically stated that the monarch's power to
prorogue Parliament is not affected by the Act. Nonetheless, the Supreme Court's 2019 judgment in
Miller II established that the prerogative of prorogation is not absolute. The appointment of the prime minister is also, theoretically, governed by the royal prerogative. Technically the monarch may appoint as prime minister anyone he wants to appoint, but in practice the appointee is always the person who is best placed to command a majority in the House of Commons. Usually, this is the leader of the political party that is returned to Parliament with a majority of seats after a general election. Difficulties may result with a so-called
hung parliament, in which no party commands majority support, as last occurred
in 2017. In this situation, constitutional convention is that the previous incumbent has the first right to form a coalition government and seek appointment. If the prime minister decides to retire in the middle of a parliamentary session, then unless there is a clear "prime minister-in-waiting" (e.g.,
Neville Chamberlain in 1937 or
Anthony Eden in 1955) the monarch in principle has to choose a successor (after taking appropriate advice, not necessarily from the outgoing prime minister), but the last monarch to be actively involved in such a process was George V, who appointed
Stanley Baldwin rather than
Lord Curzon in 1923. In more modern times, the monarch left it to the politicians involved to choose a successor through private consultations (
Winston Churchill in May 1940,
Harold Macmillan in January 1957,
Alec Douglas-Home in October 1963). Nowadays, the monarch has no discretion, as the governing party will elect a new leader who will near-automatically be appointed as he or she commands the support of the majority of the Commons (most recently
Theresa May in 2016,
Boris Johnson in 2019,
Liz Truss and
Rishi Sunak in 2022).
Judicial system The most noted prerogative power that affects the judicial system is the
prerogative of mercy, which has two elements: the granting of pardons and the granting of
nolle prosequi. Pardons may eliminate the "pains, penalties and punishments" from a criminal conviction, though they do not remove convictions themselves. This power is commonly exercised on the advice of the
Secretary of State for the Home Department; the monarch has no direct involvement in its use. Exercises of this power may also take the form of commutations, a limited form of pardon where the sentence is reduced, on certain conditions. The granting of a pardon is not subject to judicial review, as confirmed by
Council of Civil Service Unions v Minister for the Civil Service, but the courts have chosen to criticise its application or lack thereof, as in
R v Secretary of State for the Home Department, ex parte Bentley. Granting
nolle prosequi is done by the
Attorney General for England and Wales (or the equivalent in Scotland or Northern Ireland) in the name of the Crown, to stop legal proceedings against an individual. This is not reviewable by the courts, as confirmed by
R v Comptroller-General of Patents, ex parte Tomlinson, and does not count as an acquittal; the defendant may be brought before the courts on the same charge at a later date.
Foreign affairs The royal prerogative is in much use in the realm of foreign affairs. It is the monarch who recognises foreign states (although several statutes regulate the immunities enjoyed by their heads and diplomatic representatives), issues declarations of war and peace, and forms international treaties. The monarch also has the power to annex territory, as was done in 1955 with the island of
Rockall. Once territory has been annexed, the monarch has complete discretion as to the extent to which the government will take over the former government's liabilities; this was confirmed in
West Rand Central Gold Mining Company v The King. Monarchs also have the power to alter British territorial waters and cede territory. Their freedom to do these things in practice is doubtful, in that they might deprive British citizens of their nationality and rights. When the island of
Heligoland was ceded to Germany in 1890, parliamentary approval was first sought. Monarchs can also regulate colonies and dependent territories by exercising the prerogative through
Orders in Council. The courts have long fought against the monarch's use of this power: in
R (Bancoult) v Secretary of State for Foreign and Commonwealth Affairs (No 2), the Court of Appeal ruled that using Orders-in-Council to frustrate judicial rulings was an unlawful abuse of power, although this ruling was later overturned. A judgment delivered in the
Court of Appeal in 1988 (
ex parte Everett), and re-stated in a ruling of the
High Court delivered in July 2016, confirmed that granting or withdrawing
British passports has always been an exercise of the royal prerogative, and continues to be exercisable at the Secretary of State's discretion. Under the common law, citizens have the right freely to leave and enter the United Kingdom. In
R v Foreign Secretary, ex parte Everett, the courts held that it was their right to review the granting of passports to, and the withholding of passports from, British citizens. The writ of
ne exeat regno is also used to prevent a person leaving the country. The right to make treaties is a disputed prerogative power: under Blackstone's definition, a prerogative power must be one unique to the monarch. It has been held that the use of the prerogative in the sphere of foreign affairs is non-justiciable because of their subject-matter. This is known as the
Crown act of state doctrine.
Other prerogative powers Monarchs also have power to exercise their prerogative over the granting of
honours. Although the granting of most honours is normally decided by the executive, the monarch is still the person who technically awards them. Exceptions to this rule are membership of the
Order of the Garter, the
Order of the Thistle, the
Order of Merit, the
Royal Victorian Order and the
Royal Victorian Chain, which the monarch has complete discretion to grant. The right to bear the
royal arms is a royal prerogative.
Crown copyright applies
in perpetuity to depictions of the royal arms and its constituent parts under the royal prerogative, and
The National Archives restricts rights to reproduce them. Although Crown copyright usually expires 50 years after publication, Section 171(b) of the
Copyright, Designs and Patents Act 1988 made an exception for 'any right or privilege of the Crown' not written in an act of parliament. The prerogative empowers the monarch to appoint bishops and archbishops in the
Church of England, and to regulate the printing and licensing of the
Authorised (King James) Version of the Bible. The monarch also exerts a certain influence power on their weekly and closed conversations with the Prime Minister of the United Kingdom. In relation to the armed forces, the monarch is the Commander in Chief, and members are regulated under the royal prerogative. Most statutes do not apply to the armed forces, although some areas, such as military discipline, are governed by Acts of Parliament. Under the
Crown Proceedings Act 1947, the monarch is the sole authority for the armed forces, and as such their organisation, disposition and control cannot be questioned by the courts. This exercise of prerogative power gives the Crown authority to recruit members of the armed forces, appoint commissioned officers, and establish agreements with foreign governments to station troops in their territory.
R v Secretary of State for the Home Department, ex parte Northumbria Police Authority, recognised that the prerogative also includes the power to "take all reasonable steps to preserve the
Queen's peace", and in
Burmah Oil Co. v Lord Advocate, the House of Lords took the view that it extended to "doing all those things in an emergency which are necessary for the conduct of [the Second World War]." ==Use==
