Royal prerogative

The royal prerogative is a specific body of authority and privilege. It is recognized in common law and some civil law systems. These powers belong to a sovereign, such as a monarch. In many modern nations, these powers are used to carry out executive functions. This means they help the government manage the affairs of the state. While the powers technically belong to the monarch, they are often held by the government. This system helps the state function through established legal traditions.

These powers operate through two main mechanisms. The first category includes powers exercised directly by government ministers. In the United Kingdom, ministers use these powers without needing parliamentary approval. They use them to regulate the civil service or issue passports. The second category involves powers exercised nominally by the monarch. In these cases, the monarch acts "on the advice of" the prime minister or the cabinet. This is a constitutional convention that ensures the government makes the actual decisions. This structure separates the symbolic role of the monarch from the active role of the government.

There are distinct ways these powers are applied across different nations. In some constitutional monarchies, like Denmark, Norway, and Sweden, the prerogative is largely ceremonial. It serves a formal function within the state power. In other places, the powers are more active in governance. In the United Kingdom, the prerogative includes the right to ratify treaties. It also includes mineral rights for all gold and silver ores. These different types of usage show how much influence the monarch still holds in practice.

History shows a long shift in how these powers are controlled. Originally, British monarchs exercised these powers without needing consent from Parliament. This changed significantly following the Glorious Revolution of 1688. During this time, William III and Mary II were invited to take the throne. Since the accession of the House of Hanover, the prime minister or Cabinet has advised the monarch. This shift ensured that the government remained accountable to Parliament. Over time, many of these powers have been turned into statutory laws passed by legislatures.

Legal limits on these powers have been established by the courts. In 1611, the Case of Proclamations established a major rule. Judges in the English common law courts asserted their right to determine the limits of the prerogative. This confirmed that the judiciary has the power to say what the law is. This is a vital part of the judicial power. It keeps the executive power of the Crown separate from the legal power of the courts. Because the British constitution is uncodified, the courts act as the final arbiter of these powers.

In Commonwealth realms, the prerogative follows specific national rules. In Canada, the Constitution Act of 1867 outlines many of these powers. The Crown has the authority to declare war and deploy armed forces. However, this power is exercised by the federal Cabinet. The Canadian government has also used the prerogative to deny passports to specific citizens. In Australia, the prerogative resides in the monarch but is exercised by the governor-general. This includes authority over military affairs as defined by the Australian Constitution.

Even in overseas territories, the application of these powers can be complex. In the 1774 case of Campbell v. Hall, the absolute authority of the Crown in colonies was limited. The court decided that once a colony has a representative assembly, the Crown needs consent to change laws or raise taxes. There have also been modern legal battles regarding these powers. In the Chagos Archipelago, the House of Lords ruled in 2008 that an Order in Council was a lawful exercise of authority. This case involved the movement of residents to make way for a US air base in the 1960s. While the Law Lords noted the decision was morally wrong, they found it legally valid.
