The Rule of Law

Introduction

The rule of law is a fundamental constitutional principle that underpins the entire English legal system. It holds that no one is above the law — not the government, not the monarch, and not any individual. The concept provides a framework for how state power should be exercised and ensures that citizens are protected from arbitrary authority. For AQA A-Level Law, you need to understand Dicey's formulation of the rule of law, modern challenges to the principle, and its relationship with parliamentary sovereignty and judicial review.

A.V. Dicey and the Rule of Law

The most influential formulation of the rule of law in English constitutional law comes from Albert Venn Dicey (1835–1922), a constitutional lawyer and academic. In his landmark work An Introduction to the Study of the Law of the Constitution (1885), Dicey identified three key principles that together constitute the rule of law.

Principle 1: No Arbitrary Punishment

"No man is punishable or can be lawfully made to suffer in body or goods except for a distinct breach of law established in the ordinary legal manner before the ordinary courts of the land."

This principle means:

• A person can only be punished for a breach of an existing law.
• There must be a clear legal rule that has been broken — the state cannot punish people for conduct that was not illegal when it was committed.
• Any punishment must be imposed by the ordinary courts following a proper legal process.
• The state cannot exercise arbitrary power over individuals.

Implications:

• Laws should be prospective (forward-looking), not retrospective. Creating a law today and punishing someone for conduct they engaged in last year is contrary to this principle.
• The principle is connected to the concept of legal certainty — citizens must be able to know in advance what is and is not lawful.
• It relates to the Latin maxim nullum crimen sine lege — "no crime without law."

Challenges to this principle:

• War Crimes Act 1991 — This Act allows prosecution for war crimes committed during World War II, even though the conduct may not have been a crime under English law at the time. It is therefore retrospective.
• Anti-terrorism legislation — Powers under the Terrorism Act 2000 and subsequent Acts allow for detention and control orders that some argue verge on arbitrary punishment.
• ASBO/Civil Injunction orders — Anti-Social Behaviour Orders (and their replacement under the Anti-Social Behaviour, Crime and Policing Act 2014) can restrict an individual's conduct in ways that may seem disproportionate.

Principle 2: Equality Before the Law

"No man is above the law, but every man, whatever be his rank or condition, is subject to the ordinary law of the realm and amenable to the jurisdiction of the ordinary tribunals."

This principle means:

• Everyone — including government officials, police officers, and even the Prime Minister — is subject to the same law and the same courts.
• There should not be separate courts or special legal rules for government officials (unlike some European systems, which have separate administrative courts).
• The law applies equally regardless of a person's wealth, status, or power.

Challenges to this principle:

• Diplomatic immunity — Foreign diplomats cannot be prosecuted in UK courts under the Diplomatic Privileges Act 1964, regardless of what offences they commit.
• Parliamentary privilege — Members of Parliament cannot be sued for defamation for statements made in parliamentary proceedings (Bill of Rights 1689, Article 9).
• Judicial immunity — Judges cannot be sued for actions taken in the course of their judicial duties.
• Wealth and access to justice — In practice, wealthy individuals can afford better legal representation, making the law more effective for them than for those who cannot afford it. The cuts to legal aid under the Legal Aid, Sentencing and Punishment of Offenders Act 2012 (LASPO) have exacerbated this inequality.
• Crown immunity — Historically, the Crown could not be prosecuted. While the Crown Proceedings Act 1947 allowed civil claims against the Crown, some immunities remain.

Principle 3: The Constitution Arises from the Ordinary Law

"The general principles of the constitution are the result of judicial decisions determining the rights of private persons in particular cases brought before the courts."

This principle means:

• In the UK, constitutional rights are not found in a single written document but arise from the common law and from specific statutes.
• Individual rights are protected through ordinary court cases, not through an abstract constitutional declaration.
• The constitution is the product of the ordinary law of the land, particularly judicial decisions.

Implications:

• Dicey was contrasting the UK position with countries that have a codified constitution (such as the USA or France), where rights are set out in a single document.
• In the UK, rights have historically been developed through cases — for example, the right to freedom of expression was developed through defamation cases and the law of contempt.

Challenges to this principle:

• The Human Rights Act 1998 incorporated the European Convention on Human Rights into UK law, creating a set of defined rights more akin to a written constitution.
• The European Union (prior to Brexit) imposed a body of law that took precedence over ordinary UK law.
• The increasing use of statute law rather than common law to define rights arguably moves the UK away from Dicey's model.

Modern Interpretations of the Rule of Law

While Dicey's formulation remains central to the AQA specification, several modern thinkers have developed and expanded the concept.

Lord Bingham — The Rule of Law (2010)

Lord Bingham, a former Senior Law Lord, identified eight sub-rules that make up the rule of law in his influential book The Rule of Law (2010):

1. The law must be accessible and so far as possible intelligible, clear, and predictable.
2. Questions of legal right and liability should be resolved by application of the law and not by the exercise of discretion.
3. The laws of the land should apply equally to all, except where objective differences justify differentiation.
4. Ministers and public officers must exercise their powers in good faith, fairly, and for the purpose for which they were conferred, without exceeding limits.
5. The law must afford adequate protection of fundamental human rights.
6. Means must be provided for resolving, without prohibitive cost or inordinate delay, bona fide civil disputes.
7. Adjudicative procedures provided by the state should be fair.
8. The state must comply with its obligations in international law.

Lord Bingham's version is broader than Dicey's, incorporating human rights, international law, and concerns about access to justice.

Joseph Raz — Formal and Substantive Rule of Law

Joseph Raz distinguished between a formal (or "thin") conception of the rule of law, which focuses on how laws are made and applied (clarity, stability, prospectivity), and a substantive (or "thick") conception, which requires the law to uphold certain moral values such as human rights and dignity.
