Constitutional Law
Constitution and Constitutionalism
Understand the difference between a constitution and constitutionalism, including limited government, rule of law, rights and judicial review.
The short answer
A constitution creates and distributes public power; constitutionalism ensures that the same power remains limited, accountable and subject to law.
What a constitution does
A constitution is the basic legal framework of a political community. It identifies institutions, allocates authority, protects interests and provides a method for lawful change.
Organises public power
It creates institutions such as the legislature, executive and judiciary, defines their powers and regulates their relationship with citizens and with one another.
Written and unwritten
A written constitution is mainly found in an authoritative text. An uncodified constitution draws more heavily on statutes, decisions and conventions. The distinction concerns form, not whether rules exist.
Rigid and flexible
A rigid constitution requires a special amendment process, while a flexible one can be changed more like ordinary law. India combines both methods because different provisions require different procedures.
Federal and unitary
A federal constitution divides authority between two levels of government. A unitary system concentrates ultimate legal authority at the national level. India has federal foundations with several centralising features.
Constitutionalism means limited government
A country may possess a document called a constitution and still lack constitutionalism if rulers can ignore limits without an effective remedy.
Rule of law
Public authorities must act under valid law, exercise power for lawful purposes and remain answerable before independent institutions.
Rights and remedies
Rights restrain State power, while Articles 32 and 226 make those restraints enforceable. A right without an accessible remedy is easily reduced to a promise.
Checks and accountability
Separation of functions, legislative responsibility, judicial review, free elections and public reasons reduce the risk of arbitrary or concentrated power.
Basic structure
Even the constitutional amendment power is limited. Parliament may change the Constitution, but it cannot destroy its basic identity.
Written, unwritten, rigid and flexible constitutions
Classifications describe how constitutional rules are found and changed, but no modern system fits perfectly into one box.
Written and codified
A written constitution places foundational rules in an authoritative text. Statutes, conventions, judgments and institutional practice can still supplement that text.
Uncodified constitution
An uncodified system draws constitutional rules from statutes, common law, conventions and authoritative practice rather than one supreme document.
Rigid amendment
A rigid constitution requires a procedure more demanding than ordinary legislation, which protects stability but can make formal change slower.
Flexible amendment
A flexible constitution allows substantial change through ordinary political processes. Flexibility does not mean that government is legally unlimited.
The essential elements of constitutionalism
A country may possess a constitutional document without practising constitutionalism. The real test is whether public power is limited and accountable.
Rule of law
Public power must rest on law, operate through fair and non-arbitrary standards and remain open to review by independent institutions.
Separation and checks
Legislative, executive and judicial functions are institutionally distributed so that no authority becomes judge of every limit on its own power.
Rights and remedies
Rights constrain majorities and officials, while effective remedies allow courts and other institutions to respond when those constraints are violated.
Responsible government
Elections, legislative confidence, reasons, transparency, federal accountability and independent oversight make authority answerable to constitutional standards.
Limited government under the Indian Constitution
Indian constitutionalism limits every organ through text, structure, rights, federal distribution and the basic-structure doctrine.
Parliament and State Legislatures possess broad democratic authority, but their laws must remain within legislative competence and constitutional rights. The executive acts under the Constitution and law. Courts exercise judicial review while remaining bound by jurisdiction, precedent and constitutional limits.
Kesavananda Bharati established that even the Article 368 amending power cannot damage the basic structure. Minerva Mills connected limited amending power, judicial review and harmony between Parts III and IV. A problem answer should therefore identify the power used, its source, the applicable limit, the reviewing institution and the remedy.
Leading cases and what they establish
Read each authority for the proposition it proves, the legal question it answers and the reasoning that supports the result.
Kesavananda Bharati v. State of Kerala
(1973) 4 SCC 225
Facts: A religious institution challenged Kerala land-reform laws while constitutional amendments had expanded Parliament’s power and protected redistributive legislation from rights review.
Legal question: Can Parliament use Article 368 to change any part of the Constitution without an enforceable substantive limit?
Held: Parliament has wide power to amend the Constitution, but it cannot alter or destroy its basic structure.
Reasoning: The amendment power is broad enough to change every provision, but the word and function of amendment require the Constitution to survive with its basic identity intact.
Why it matters: Use it to show that constitutionalism limits even a formally conferred amendment power.
Read the judgmentIndira Nehru Gandhi v. Raj Narain
1975 Supp SCC 1
Facts: While the Prime Minister’s election dispute was pending, the Thirty-ninth Amendment attempted to place that election beyond ordinary judicial adjudication.
Legal question: Could a constitutional amendment decide or immunise a specific election dispute in a way that displaced judicial process?
Held: An amendment placing a particular election dispute beyond ordinary adjudication violated basic features including democracy, equality and the rule of law.
Reasoning: Constituent power could not be used as a substitute for adjudication or to damage democracy, equality, free elections and the rule of law, which form part of the basic structure.
Why it matters: Use it as a concrete example of constitutional power crossing a constitutional limit.
Minerva Mills Ltd. v. Union of India
(1980) 3 SCC 625
Facts: The Forty-second Amendment claimed an unlimited amending power and attempted to prevent courts from reviewing constitutional amendments.
Legal question: Can Parliament enlarge Article 368 so that its own amendment power becomes unlimited and unreviewable?
Held: Limited amending power and judicial review form part of the basic structure; a power to destroy the Constitution cannot be treated as a power to amend it.
Reasoning: A limited power cannot convert itself into an unlimited one. Judicial review and harmony between Fundamental Rights and Directive Principles preserve the Constitution’s basic identity.
Why it matters: Use it for limited government and the difference between amendment and constitutional destruction.

Questions students ask
What is the simplest difference between constitution and constitutionalism?
A constitution states how power is organised. Constitutionalism requires that public power be limited, accountable and exercised according to those higher rules.
Is every written constitution rigid?
No. Written form and amendment difficulty are separate questions. A written constitution may contain both easier and more demanding amendment procedures.
Can a country have a constitution without constitutionalism?
Yes. A document may organise government while failing to limit arbitrary power, protect rights or provide effective accountability. Constitutionalism concerns the operation of limited government.
Is separation of powers absolute in India?
No. India uses functional separation with checks and overlaps. The constitutional concern is preservation of institutional boundaries, accountability and judicial independence rather than a watertight division.
How does basic structure support constitutionalism?
It prevents the constituted amending power from destroying foundational features such as constitutional supremacy, judicial review, democracy and limited government.
