The Rule of Law: Foundation of Constitutional Governance

When a powerful official can detain you without legal cause, or when the rich escape consequences that ordinary people cannot, something fundamental has broken down. That “something” is the rule of law. It is the principle that governments must act according to known, established legal rules rather than the personal whims of those in power. The idea sits at the very heart of constitutional governance, and understanding it explains why democracies invest so heavily in courts, constitutions, and the separation of powers.

What the rule of law actually means 🔗

At its core, the rule of law holds that everyone, including the government itself, is bound by and accountable to law that is publicly known and fairly applied. No person or institution stands above the law. Power flows from legal authority, not from rank, wealth, or office.

The phrase was popularised by the British jurist A.V. Dicey in his 1885 work Introduction to the Study of the Law of the Constitution. Dicey did not invent the concept, which stretches back to Aristotle, but he gave it a clear framework that still anchors constitutional discussion today. He broke the rule of law into three core components: the absence of arbitrary power, equality before the law, and the predominance of the legal spirit.

Absence of arbitrary power 🔗

Dicey’s first principle states that no person should be punished or made to suffer except for a clear breach of law, established through ordinary legal proceedings before ordinary courts. The government cannot act on whim or personal vendetta. As Dicey himself warned, wherever officials hold wide, unregulated discretion, the freedom of citizens is at risk. Predictability is the goal: people should be able to know in advance what the law requires.

Equality before the law 🔗

The second principle insists that everyone is subject to the same ordinary law, administered by the same ordinary courts, regardless of rank or status. A minister breaking the law faces the same tribunals as any private citizen. No man is above the law, as the old maxim “Be you ever so high, the law is above you” captures.

Predominance of the legal spirit 🔗

Dicey’s third principle reflected his belief, rooted in the British unwritten constitution, that individual rights were best protected through the decisions of ordinary courts rather than through abstract constitutional declarations. In Britain, he argued, the general principles of the constitution were the result of judicial decisions determining the rights of private persons in actual cases.

Why an independent judiciary is essential 🔗

The rule of law is only as strong as the institution that enforces it. Laws on paper mean little if there is no impartial body to interpret them and to hold the government accountable when it oversteps. This is why an independent judiciary is treated as a non-negotiable part of constitutional governance.

Independence means judges can decide cases according to law without fear of political reprisal or hope of reward. They must be free to rule against the very government that appointed them. Without this independence, the courts become an extension of executive power, and the promise of equality before the law collapses into empty words.

The Supreme Court has spelt out what this requires in practice. In Bachan Singh v. State of Punjab, the Court observed that the rule of law rests on three pillars: that law-making must be done by a democratically elected legislature, that even the legislature cannot wield unlimited power, and that there must be an independent judiciary to protect citizens from misuse of power by the legislature and the executive.

Judicial review: the rule of law’s sharpest tool 🔗

If an independent judiciary is the guardian of the rule of law, judicial review is its most powerful instrument. Judicial review is the power of courts to examine the actions of the legislature and the executive and to strike them down if they conflict with the constitution. It transforms the constitution from a statement of ideals into an enforceable limit on power.

The American origin: Marbury v. Madison 🔗

The doctrine of judicial review was crystallised in the United States in the 1803 case Marbury v. Madison. This was the first time the Supreme Court invalidated a law passed by Congress. Chief Justice John Marshall, writing for the Court, reasoned that the Constitution is the supreme law of the land and that any ordinary law repugnant to it must be void.

Interestingly, the US Constitution does not expressly grant courts this power. The Supreme Court established the doctrine itself by interpreting the logic of a written, supreme constitution. Marshall held a section of the Judiciary Act of 1789 unconstitutional, and in doing so asserted that it is the judiciary’s authority to assess the constitutionality of statutes and invalidate those that violate the Constitution. This single decision reshaped the balance of power among the branches of government and made the judiciary a genuine co-equal partner.

Why judicial review protects liberty 🔗

Judicial review matters because legislatures, even elected ones, can pass laws that trample on individual rights or concentrate power dangerously. The power to overturn unconstitutional laws gives citizens a meaningful remedy. It is the mechanism that allows courts to prevent abuses such as civil rights violations and to compel officials to act within constitutional limits. By policing the boundary between lawful and unlawful state action, judicial review keeps the rule of law from becoming a mere slogan.

How the rule of law is embedded in the Constitution 🔗

The framers of the Constitution absorbed the rule of law through two channels: the British constitutional tradition that Dicey articulated, and the Constituent Assembly’s deliberate choice to entrench equality, liberty, and judicial oversight directly in the text. The result is a written constitution that distributes Dicey’s principles across several key provisions.

Article 14 and equality before the law 🔗

Article 14 is the most direct textual expression of Dicey’s equality principle. It declares that the State shall not deny to any person equality before the law or the equal protection of the laws. The first expression, “equality before the law,” is of British origin and is a negative concept that prohibits special privileges. The second, “equal protection of the laws,” is borrowed from the American Constitution and requires that people in similar situations be treated alike.

The courts have read Article 14 expansively. It does not merely forbid open discrimination; it prohibits arbitrary state action of every kind. Any classification a law draws must satisfy two tests: there must be an intelligible difference between the groups, and that difference must bear a rational connection to the law’s purpose. This is how the equality guarantee adapts to address real-world inequality without descending into mechanical sameness.

Articles 13 and 21 🔗

Article 13 gives judicial review its constitutional anchor, empowering courts to strike down any law or executive action that violates the fundamental rights in Part III. Article 21 protects life and personal liberty. In the landmark Maneka Gandhi v. Union of India (1978), the Supreme Court held that any procedure restricting liberty must be fair, just, and reasonable, not merely formally enacted. A law cannot escape scrutiny simply because it was passed correctly; its substance must also meet constitutional standards.

The basic structure doctrine 🔗

The rule of law received its strongest constitutional shield in Kesavananda Bharati v. State of Kerala (1973). By a narrow 7-6 majority, the Supreme Court held that while Parliament can amend the Constitution under Article 368, it cannot alter or destroy its basic structure. The Court identified core features that lie beyond Parliament’s reach, including democracy, separation of powers, the rule of law and the independence of the judiciary.

Crucially, the Court treated judicial review itself as part of this basic structure, meaning Parliament cannot strip the courts of their power to test laws against the Constitution. The doctrine ensures that all laws and constitutional amendments remain subject to judicial review, with the Supreme Court as the final interpreter. This is the rule of law operating at its most fundamental level: even the power to amend the highest law is itself bounded by law.

The gap between principle and practice 🔗

The rule of law is an aspiration as much as an achievement. Dicey’s vision of perfect equality before the law is complicated in practice by unequal access to legal resources, which means wealthier litigants often navigate the system more effectively than the poor. Global assessments reflect this gap. The World Justice Project’s Rule of Law Index 2025 ranked India 114 out of 143 countries on civil justice and 89 out of 143 on criminal justice, pointing to the distance between constitutional promise and daily reality.

Recognising this gap is not a rejection of the rule of law but a measure of the work that remains. Strong constitutional text, an independent judiciary, and the power of judicial review provide the architecture. Whether that architecture delivers genuine justice depends on enforcement, access, and the integrity of the institutions that operate within it.

What do you think? If judicial review allows unelected judges to overturn laws passed by an elected legislature, where should the line be drawn between protecting the constitution and respecting the democratic will of the majority? And given the persistent gap between the rule of law as a principle and its practice, what reform would do the most to close it?
