Is the Indian Parliament sovereign, or is its authority constrained by constitutional supremacy and judicial review when compared to the Westminster model of parliamentary sovereignty?

Parliamentary Supremacy vs Parliamentary Sovereignty: Interpreting Legislative Authority in Democratic Systems and the Indian Context

---

Introduction

The doctrines of parliamentary supremacy and parliamentary sovereignty represent distinct yet interrelated conceptions of legislative authority in democratic constitutional theory. While often used interchangeably, the terms reflect different constitutional traditions and legal norms. Parliamentary sovereignty, rooted in British constitutional jurisprudence, implies the absolute and unrestricted power of Parliament. Parliamentary supremacy, on the other hand, refers to the preeminence of the legislature within the separation of powers, but still bound by constitutional limitations, particularly in systems with written constitutions and judicial review.

This essay examines the conceptual distinction between the two doctrines, analyzes their theoretical underpinnings, and applies them to the Indian context. It argues that the Indian Parliament, while institutionally supreme within its domain, cannot be characterized as sovereign in the British sense, due to the overarching framework of constitutionalism, fundamental rights, and an empowered judiciary capable of invalidating legislative actions.

1. Doctrines Defined: Parliamentary Supremacy vs Parliamentary Sovereignty

A. Parliamentary Sovereignty: The British Model

The doctrine of parliamentary sovereignty, as theorized by A.V. Dicey, is a defining feature of the British constitutional system, which operates without a written, supreme constitution. According to Dicey:

• Parliament can make or unmake any law, and
• No person or body, including courts, can question the validity of an Act of Parliament.

In this model:

• There is no entrenched bill of rights or superior constitution,
• Parliament is not bound by precedent, and
• There is no scope for judicial review in the constitutional sense.

The UK Parliament is, therefore, legally omnipotent, subject only to political constraints and public opinion.

B. Parliamentary Supremacy: A Constitutional Limitation

In contrast, parliamentary supremacy in many liberal democracies reflects the preeminence of Parliament in law-making, but within the boundaries of a written constitution that enshrines fundamental rights, federalism, and judicial review.

• In this framework, Parliament is supreme in the legislative domain, but not sovereign in an unrestricted manner.
• The constitution functions as a higher law, and courts may strike down unconstitutional statutes, especially those violating fundamental rights or basic structural principles.

This model is evident in jurisdictions such as India, the United States, Canada, and Germany, where constitutional supremacy limits legislative authority.

2. Legislative Authority in India: Institutional Supremacy within Constitutional Bounds

A. Constitutional Supremacy and the Basic Structure Doctrine

India is a constitutional democracy, governed by a written constitution adopted in 1950, which explicitly affirms constitutional supremacy under Article 13(2):

“The State shall not make any law which takes away or abridges the rights conferred by this Part [Fundamental Rights]…”

Additionally, the Kesavananda Bharati v. State of Kerala (1973) verdict introduced the Basic Structure Doctrine, asserting that:

• Parliament has wide powers to amend the Constitution under Article 368,
• But it cannot alter the basic structure or essential features of the Constitution (e.g., rule of law, separation of powers, judicial review, secularism, federalism).

This landmark doctrine restricts Parliament’s authority and entrenches constitutionalism as the normative basis of the Indian polity.

B. Judicial Review and the Role of the Supreme Court

The Indian judiciary, particularly the Supreme Court, has been empowered under Articles 32 and 226 to enforce constitutional rights and review legislative and executive actions.

• In Minerva Mills v. Union of India (1980), the Court struck down constitutional amendments for violating the basic structure.
• In I.R. Coelho v. State of Tamil Nadu (2007), even laws placed under the Ninth Schedule were held to be subject to judicial scrutiny if they violate fundamental rights.

Thus, Parliament’s legislative power is not absolute, and Indian constitutionalism is characterized by a deliberate tension between democratic majoritarianism and constitutional limits.

3. Federalism, Fundamental Rights, and Separation of Powers

A. Federal Limitations

India’s quasi-federal structure distributes legislative authority between the Centre and the States, under the Seventh Schedule.

• Parliament cannot legislate on items in the State List, except under extraordinary circumstances (e.g., national emergency, President’s Rule, Rajya Sabha resolution under Article 249).

This federal division imposes spatial limitations on parliamentary authority, contrary to the unitary scope of British parliamentary sovereignty.

B. Entrenched Rights and Horizontal Accountability

• Fundamental rights under Part III of the Constitution act as normative constraints on legislative action.
• Citizens can challenge laws violating rights such as equality (Article 14), freedom (Article 19), and life and liberty (Article 21).
• This legal architecture ensures that constitutional morality prevails over legislative majorities.

The separation of powers, though not explicitly mentioned, has been interpreted as part of the basic structure. It ensures that Parliament cannot override the judiciary or the executive arbitrarily.

4. Can the Indian Parliament Be Considered Sovereign?

A. Arguments Against Sovereignty

• Indian Parliament is not sovereign in the Diceyan sense, as it operates under the framework of a written Constitution, and its actions are subject to judicial review.
• The presence of entrenched rights, federalism, and amendment limitations underscore the primacy of the Constitution, not the legislature.
• The Basic Structure Doctrine imposes substantive constraints even on constitutional amendments—a feature unknown in British constitutionalism.

B. Limited Supremacy in Law-Making

However, within the constitutional framework, Parliament retains supremacy in legislative matters, especially when:

• It legislates on Union or Concurrent List subjects,
• It passes money bills under Article 110, where the Rajya Sabha has limited powers,
• It initiates constitutional amendments, subject to basic structure review.

Thus, Parliament can be seen as supreme but not sovereign—its power is institutional, not juridical.

Conclusion

The distinction between parliamentary supremacy and sovereignty is crucial for understanding the nature of legislative authority in modern democracies. While sovereignty implies unbounded legislative power, supremacy acknowledges preeminence within a constitutional framework.

In India, Parliament is a powerful democratic institution, but it is not sovereign. Its authority is mediated by a written Constitution, judicial review, federalism, and fundamental rights. The supremacy of the Constitution, not of Parliament, is the foundational principle of Indian democracy.

Consequently, Indian constitutionalism prioritizes normative legitimacy over numerical majorities, embedding legislative authority within a system of institutional checks and constitutional values. This model serves not only as a guardrail against majoritarian excess but also as a blueprint for a rights-based, rule-of-law-centric democratic polity.
