Powers of the King

The phrase “Powers of the King” generally refers to the legal and constitutional powers exercised by the monarch in a monarchy, especially under the British constitutional system. Historically, the King possessed absolute authority, but over time these powers became limited by constitutional principles, parliamentary supremacy, and judicial control.

In constitutional law, these powers are commonly known as the Royal Prerogatives.

Meaning of Royal Prerogative

Royal prerogative means the special rights, powers, and immunities traditionally belonging to the Crown and exercised by the King (or Queen). In modern constitutional practice, most prerogative powers are exercised by ministers in the name of the Crown.

According to constitutional scholar A.V. Dicey:

“The prerogative appears to be the residue of discretionary or arbitrary authority left in the hands of the Crown.”

Thus, prerogative powers are those powers which:

• originate from common law,
• are not derived from statute,
• historically belonged to the monarch.

Historical Development of the King’s Powers

1. Absolute Monarchy

In medieval England, the King was considered:

• the source of law,
• head of the army,
• supreme executive authority,
• fountain of justice.

The doctrine:

“The King can do no wrong”

gave enormous authority to the Crown.

2. Limitation of Royal Power

Over centuries, several constitutional developments restricted the King’s powers:

• Magna Carta (1215)
• Petition of Right (1628)
• Bill of Rights (1689)
• Constitutional conventions
• Growth of Parliamentary democracy

Today, the monarch reigns but does not rule.

Types of Powers of the King

I. Executive Powers

The King is formally the head of the executive.

These include:

• appointment of the Prime Minister,
• appointment of ministers,
• conduct of foreign affairs,
• recognition of states,
• issuing passports,
• administration of government.

In practice, these are exercised on ministerial advice.

II. Legislative Powers

The monarch has certain legislative functions:

(a) Summoning Parliament

The King summons Parliament into session.

(b) Dissolution of Parliament

Historically, the King could dissolve Parliament.

(c) Royal Assent

No bill becomes law until the monarch gives assent.

Today this is merely formal.

III. Judicial Powers

Historically, justice flowed from the Crown.

The King:

• appointed judges,
• granted pardons,
• acted as supreme judicial authority.

Modern judicial independence has greatly restricted these powers.

IV. Military Powers

The King is the Commander-in-Chief of armed forces.

Powers include:

• declaring war,
• making peace,
• deployment of troops.

These are exercised through the government.

V. Foreign Affairs Powers

The Crown has prerogative powers concerning:

• treaties,
• diplomacy,
• recognition of foreign governments,
• passports.

However, Parliament increasingly supervises these powers.

VI. Mercy Powers

The King possesses the prerogative of mercy:

• pardon,
• remission of punishment,
• commutation of sentence.

This is exercised on ministerial advice.

Nature of Modern Royal Powers

Modern constitutional monarchy is based on:

1. Parliamentary sovereignty
2. Rule of law
3. Responsible government
4. Constitutional conventions

Thus:

• The King acts on advice.
• Ministers are politically responsible.
• Courts may review prerogative powers.

Important Principles Governing the King’s Powers

1. The King Cannot Override Law

The monarch cannot suspend or dispense with laws without Parliament.

2. Parliament Is Supreme

Statutes prevail over prerogative powers.

3. Courts Can Review Prerogative Powers

Judicial review now extends to many prerogative acts.

4. Ministers Are Responsible

Though powers belong formally to the Crown, ministers are accountable.

Important Case Laws on Powers of the King

1. Case of Proclamations (1611)

Case of Proclamations

Facts

King James I issued proclamations prohibiting construction in London and manufacture of starch without Parliamentary approval.

Issue

Can the King create new law through proclamation?

Judgment

Chief Justice Coke held:

• The King cannot create new offences or laws by proclamation.
• The King has no prerogative except that allowed by law.

Principle Established

The monarch cannot legislate without Parliament.

This case laid the foundation for constitutional limitation on royal authority.

2. Entick v Carrington (1765)

Entick v Carrington

Facts

Government officers entered Entick’s house under authority of a warrant issued by the Secretary of State.

Issue

Could the Crown authorize actions without legal authority?

Judgment

The court held the search unlawful.

Lord Camden stated:

If it is law, it will be found in our books; if not found there, it is not law.

Principle Established

• Executive power must have legal basis.
• The Crown cannot interfere with individual liberty arbitrarily.

This became a cornerstone of civil liberties and rule of law.

3. Attorney General v De Keyser’s Royal Hotel Ltd. (1920)

Attorney General v De Keyser's Royal Hotel Ltd.

Facts

During World War I, the government took possession of a hotel under prerogative powers without compensation.

Issue

Can prerogative powers operate where statute already governs the matter?

Judgment

The House of Lords held:

• When Parliament legislates on a subject, statutory power replaces prerogative power.

Principle Established

Statute overrides prerogative.

This case strongly affirmed parliamentary supremacy.

4. Burmah Oil Co. v Lord Advocate (1965)

Burmah Oil Co. v Lord Advocate

Facts

British forces destroyed oil installations in Burma during wartime to prevent enemy capture.

Issue

Whether compensation was payable for destruction under royal prerogative.

Judgment

The House of Lords held compensation was payable.

Principle Established

Even wartime prerogative powers may attract legal liability and judicial scrutiny.

5. Council of Civil Service Unions v Minister for the Civil Service (GCHQ Case) (1985)

Council of Civil Service Unions v Minister for the Civil Service

Facts

The government banned trade union membership at GCHQ using prerogative powers related to national security.

Issue

Can prerogative powers be judicially reviewed?

Judgment

The House of Lords held:

• Prerogative powers are generally reviewable by courts.
• However, matters involving national security may limit review.

Principle Established

Judicial review applies to prerogative powers.

This is one of the most important modern constitutional law cases.

6. R (Miller) v Secretary of State for Exiting the European Union (2017)

R (Miller) v Secretary of State for Exiting the European Union

Facts

The UK government sought to trigger Article 50 (Brexit process) using prerogative powers.

Issue

Can the government alter domestic law through prerogative powers without Parliament?

Judgment

The UK Supreme Court held:

• The government could not trigger Article 50 without Parliamentary authorization.

Principle Established

Prerogative powers cannot change domestic law or remove statutory rights.

7. R (Miller) v The Prime Minister (2019) — Prorogation Case

R (Miller) v The Prime Minister

Facts

Prime Minister Boris Johnson advised the Queen to prorogue Parliament for five weeks during Brexit debates.

Issue

Whether the advice to prorogue Parliament was lawful.

Judgment

The UK Supreme Court declared the prorogation unlawful.

Principle Established

• Even constitutional prerogatives are subject to judicial review.
• Executive action cannot frustrate parliamentary democracy.

Constitutional Conventions Limiting the King

Though legal powers remain formally with the Crown, conventions require the monarch to:

• act on ministerial advice,
• remain politically neutral,
• avoid personal interference in governance.

Examples:

• appointing the leader of majority party as Prime Minister,
• granting Royal Assent automatically,
• not vetoing legislation.

Modern Position of the King

Today, the monarch’s role is largely:

• ceremonial,
• symbolic,
• constitutional.

The famous principle is:

“The King reigns but does not rule.”

Actual governance is carried out by:

• Prime Minister,
• Cabinet,
• Parliament.

Critical Evaluation

Advantages of Royal Powers

• Constitutional continuity
• Political neutrality
• Symbol of national unity
• Stability in governance

Criticisms

• Undemocratic origin
• Lack of direct accountability
• Some prerogatives remain vague
• Potential executive misuse

Conclusion

The powers of the King evolved from absolute authority to constitutionally restricted powers under parliamentary democracy. While the monarch historically controlled legislation, justice, war, and administration, modern constitutional law subjects these powers to:

• Parliament,
• rule of law,
• constitutional conventions,
• judicial review.

The development of royal prerogative illustrates the gradual triumph of constitutionalism over arbitrary power. Landmark decisions such as the Case of Proclamations, Entick v Carrington, De Keyser’s Royal Hotel, GCHQ, and the Miller cases firmly establish that even the Crown is subordinate to law and constitutional principles.
