Reserve power in the context of "Monarchy of Jamaica"

The monarchy of Saint Kitts and Nevis is a system of government in which a hereditary monarch is the sovereign and head of state of Saint Kitts and Nevis. The current monarch of Saint Kitts and Nevis, since 8 September 2022, is King Charles III. As sovereign, he is the personal embodiment of the Crown of Saint Kitts and Nevis. Although the person of the sovereign is equally shared with 14 other independent countries within the Commonwealth of Nations, each country's monarchy is separate and legally distinct. As a result, the current monarch is officially titled King of Saint Christopher and Nevis and, in this capacity, he and other members of the royal family undertake public and private functions domestically and abroad as representatives of Saint Kitts and Nevis. However, the King is the only member of the royal family with any constitutional role.

All executive authority is vested in the monarch, and royal assent is required for the National Assembly of Saint Kitts and Nevis to enact laws and for letters patent and Orders in Council to have legal effect. Most of the powers are exercised by the elected members of parliament, the ministers of the Crown generally drawn from amongst them, and the judges and justices of the peace. Other powers vested in the monarch, such as dismissal of a prime minister, are significant but are treated only as reserve powers and as an important security part of the role of the monarchy.

A prime minister, also known as a chief of cabinet, chief minister, first minister, minister-president or premier, is the head of the cabinet and the leader of the ministers in the executive branch of government, often in a parliamentary or semi-presidential system. A prime minister is not the head of state, but rather the head of government, serving as the chief of the executive under either a monarch or a president in a republican form of government.

In parliamentary systems of government (be they constitutional monarchies or parliamentary republics), the Prime Minister (or occasionally a similar post with a different title, such as the Chancellor of Germany) is the most powerful politician and the functional leader of the state, by virtue of commanding the confidence of the legislature. The head of state is typically a ceremonial officer, though they may exercise reserve powers to check the Prime Minister in unusual situations.

A monarch is the head of a monarchy, a form of government in which a state is ruled by an individual who normally rules for life or until abdication, and typically inherits the throne by birth. Monarchs may be autocrats (as in all absolute monarchies) or may be ceremonial figureheads, exercising only limited or no reserve powers at all, with actual authority vested in a legislature and/or executive cabinet (as in many constitutional monarchies). In many cases, a monarch will also be linked with a state religion. Most states only have a single monarch at any given time, although a regent may rule when the monarch is a minor, not present, or otherwise incapable of ruling. Cases in which two monarchs rule simultaneously over a single state, as is the current situation in Andorra, are known as coregencies.

A variety of titles are applied in English; for example, "king" and "queen", "prince" and "princess", "grand duke" and "grand duchess", "emperor" and "empress". Although they will be addressed differently in their local languages, the names and titles in the list below have been styled using the common English equivalent. Roman numerals, used to distinguish related rulers with the same name, have been applied where typical.

The monarchy of Belize is a system of government in which a hereditary monarch is the sovereign and head of state of Belize. The current Belizean monarch and head of state, since 8 September 2022, is King Charles III. As sovereign, he is the personal embodiment of the Belizean Crown. Although the person of the sovereign is shared with 14 other independent countries within the Commonwealth of Nations, each country's monarchy is separate and legally distinct. As a result, the current monarch is officially titled King of Belize and, in this capacity, he and other members of the royal family undertake public and private functions as representatives of the Belizean state. However, the King is the only member of the royal family with any constitutional role.

All executive authority is vested in the monarch, and royal assent is required for the National Assembly to enact laws and for letters patent and Orders in Council to have legal effect. Most of the powers are exercised by the elected members of parliament, government ministers, and judges. Other powers vested in the monarch are significant but are treated only as reserve powers and as an important security part of the role of the monarchy.

The President of Germany, officially titled the Federal President of the Federal Republic of Germany (German: Bundespräsident der Bundesrepublik Deutschland), is the head of state of Germany. The current officeholder is Frank-Walter Steinmeier who was elected on 12 February 2017 and re-elected on 13 February 2022. He is currently serving his second five-year-term, which began on 19 March 2022.

Under the 1949 constitution (Basic Law) Germany has a parliamentary system of government in which the chancellor (similar to a prime minister or minister-president in other parliamentary democracies) is the head of government. The president has a ceremonial role as figurehead, but also has the right and duty to act politically. They can give direction to general political and societal debates and have some important "reserve powers" in case of political instability (such as those provided for by Article 81 of the Basic Law). The president also holds the prerogative to grant pardons on behalf of the federation. The German presidents, who can be elected to two consecutive five-year terms, have wide discretion about how they exercise their official duties.

The governor-general of Australia is the federal representative of the monarch of Australia, currently Charles III. The governor-general has many constitutional and ceremonial roles in the Australian political system, in which they have independent agency. However, they are generally bound by convention to act on the advice of the prime minister and the Federal Executive Council. They also have a significant community role, through recognising meritorious individuals and groups, and representing the nation as a whole. The current governor-general is Sam Mostyn.

Significant functions of the governor-general include giving royal assent to bills passed by the houses of parliament, issuing writs for elections, exercising executive power on the advice of the Federal Executive Council, formally appointing government officials (including the prime minister, other ministers, judges and ambassadors), acting as commander-in-chief of the Australian Defence Force, and bestowing Australian honours. However, in almost all instances the governor-general only exercises de jure power in accordance with the principles of the Westminster system and responsible government. This requires them to remain politically neutral and to only act in accordance with Parliament (such as when selecting the prime minister and providing royal assent) or on the advice of ministers (when performing executive actions). However, in certain limited circumstances, the governor-general can exercise reserve powers (powers that may be exercised without or against formal advice), most notably during the 1975 Australian constitutional crisis. These situations are often controversial and the use of and continued existence of these powers remains highly debated.
