Constitutional Evolution, Features & Basic Structure — UPSC CSE Mains GS2

Weightage: the foundational GS2 subject — its provisions and doctrines are the citations every other subject in the paper draws on, and the basic structure doctrine alone recurs across questions on amendment power, federalism, secularism, and judicial review.

1. Historical underpinnings: what the Constitution inherited

The Indian Constitution did not begin from a blank page in 1947. A sequence of colonial statutes had already established much of the administrative architecture the Constituent Assembly would adapt: the Government of India Act, 1919 introduced dyarchy in the provinces, dividing subjects into transferred and reserved categories; and the Government of India Act, 1935 — by far the most significant antecedent — supplied the federal structure with a strong centre, the office of the Governor, the three-fold division of legislative subjects, the framework of the judiciary, Public Service Commissions, and the emergency provisions, much of which passed into the Constitution with modification rather than replacement. A meaningful proportion of the Constitution's text derives structurally from the 1935 Act, which is why describing the Constitution as wholly original overstates the case, and why the more interesting analytical question is not what was inherited but what was deliberately changed: the 1935 Act's structures were retained while their purpose was inverted, from instruments of colonial administrative control to instruments of representative self-government answerable to an elected legislature.

2. The borrowed-features question, read properly

The Constitution draws identifiable features from several foreign constitutions: parliamentary government and the law-making procedure from Britain; Fundamental Rights and judicial review from the United States; Directive Principles from Ireland; the federal structure with a strong centre, residuary powers vested in the Union (Article 248), and the Supreme Court's advisory jurisdiction (Article 143) from Canada; Fundamental Duties from the erstwhile Soviet constitution (added later, by the 42nd Amendment); and the amendment procedure and the Rajya Sabha election method from South Africa.

The trap in this topic is treating it as a memorisation exercise. UPSC's actual questions ask something more analytical: whether borrowing so extensively produced a coherent constitution or a patchwork. The defensible answer is that the borrowing was selective and adapted rather than transplanted — India adopted judicial review from the United States but not its rigid due process clause, instead writing "procedure established by law" into Article 21 (a formulation the Supreme Court would later expand substantively in Maneka Gandhi, 1978); it adopted federalism from Canada rather than the United States precisely because the Canadian model vests residuary power in the centre; and it adopted parliamentary government from Britain while writing it into a supreme, justiciable written constitution that Britain does not have. Each borrowing was fitted to a specific Indian requirement — national unity in a newly partitioned country, social transformation in a deeply unequal society — which is what distinguishes adaptation from imitation.

3. Fundamental Rights and Directive Principles: the relationship, and how it shifted

Fundamental Rights (Part III) are justiciable — enforceable directly through the courts, with Article 32 itself a fundamental right, which Ambedkar famously described as the heart and soul of the Constitution. Directive Principles of State Policy (Part IV) are expressly non-justiciable under Article 37, yet declared fundamental in the governance of the country and a duty of the state to apply in making laws.

The relationship between them has moved through identifiable phases rather than remaining static, and a strong answer traces the movement rather than describing the two parts separately:

• Early judicial reasoning treated Fundamental Rights as clearly prevailing where the two conflicted.
• The 42nd Amendment (1976), enacted during the Emergency, sought to invert this by giving certain Directive Principles primacy over specified Fundamental Rights.
• The 44th Amendment (1978) reversed much of that inversion after the Emergency, alongside its other corrections — most notably removing the right to property from Part III entirely and re-establishing it as a constitutional (not fundamental) right under Article 300A, and replacing "internal disturbance" with "armed rebellion" as the ground for a national emergency.
• Subsequent judicial reasoning settled on harmonious construction: the two Parts are read as complementary rather than competing, with the courts attempting to give effect to Directive Principles wherever this can be done without abrogating a Fundamental Right.

The examinable point is that the FR-DPSP relationship is a worked example of the basic structure doctrine's practical function — the 42nd Amendment's attempted inversion is precisely the kind of alteration the doctrine exists to constrain.

4. The basic structure doctrine: how it was arrived at

The doctrine did not appear fully formed. It emerged from a sustained institutional contest over the scope of Parliament's amending power under Article 368, and tracing that sequence is what a well-prepared answer does:

• Shankari Prasad (1951) and Sajjan Singh (1965) upheld Parliament's power to amend Fundamental Rights, treating a constitutional amendment as outside the meaning of "law" in Article 13.
• Golaknath (1967) reversed course, holding that Parliament could not abridge Fundamental Rights at all — a position that resolved the immediate question but left the Constitution rigid in a way that impeded land reform and other social legislation.
• Kesavananda Bharati v. State of Kerala (1973) — heard by a thirteen-judge bench, the largest in Indian judicial history, and decided by a 7:6 majority — struck the balance that has held since: Parliament can amend any part of the Constitution, including Fundamental Rights, but cannot alter or destroy its basic structure. The doctrine's genius, and the reason it has proved durable, is that it constrains amendment power without freezing the Constitution, permitting reform while placing the constitutional identity itself beyond amendment.
• Indira Nehru Gandhi v. Raj Narain (1975) then applied the doctrine to strike down a constitutional amendment for the first time, and Minerva Mills (1980) struck down parts of the 42nd Amendment, holding that limited amending power is itself part of the basic structure and reaffirming the balance between Parts III and IV.

The Court has deliberately never issued an exhaustive list of what the basic structure contains, developing it case by case instead. Elements identified across judgments include the supremacy of the Constitution, the rule of law, separation of powers, judicial review, federalism, secularism, free and fair elections, and the limited nature of the amending power itself. This open-endedness is sometimes criticised as giving the judiciary undefined power; the counter-argument is that an exhaustive list would have been simultaneously over- and under-inclusive, and that case-by-case development is how common-law doctrines are supposed to evolve.

Worked example 4.1 (illustrating a full 15-mark GS2 answer). "The basic structure doctrine has been criticised as judicial overreach with no textual basis in the Constitution. Critically examine. (15 marks, ~250 words)"

Model answer. The criticism has a genuine textual foundation. Article 368 confers amending power in unqualified terms and nowhere refers to a basic structure or any implied limitation on what may be amended. On this reading, the Court in Kesavananda Bharati (1973) created a substantive limitation the framers did not write, and — by declining to define the doctrine's contents exhaustively — reserved to itself the power to determine case by case which amendments are permissible, a power with no clear boundary and no democratic check.

Against this, the doctrine responds to a structural problem the text left unresolved: if the amending power is genuinely unlimited, Parliament could use it to dismantle the very framework from which it derives its authority, including free elections and judicial review, through formally valid procedure. The Kesavananda Court read Article 368's power to "amend" as necessarily implying the continued existence of something to amend, rather than a power to replace the Constitution with a different one.

The doctrine's subsequent record supports its practical necessity. It was invoked in Indira Nehru Gandhi (1975) against an amendment insulating the Prime Minister's election from judicial scrutiny, and in Minerva Mills (1980) against 42nd Amendment provisions that had made the amending power unlimited and subordinated Fundamental Rights to Directive Principles — precisely the Emergency-era overreach that gives the doctrine its strongest justification.

The more defensible position is that the doctrine is genuinely extra-textual but structurally sound: it constrains amendment without freezing it, and the criticism is better directed at the absence of principled criteria for identifying basic features than at the doctrine's existence.

5. Salient features worth stating precisely

Several features recur in GS2 questions and are worth holding in precise, citable form rather than as general impressions:

• Lengthiest written constitution of any sovereign country, a length driven by its federal provisions covering both Union and States, the incorporation of administrative detail inherited from the 1935 Act, and separate provisions for specific regions and communities.
• Blend of rigidity and flexibility: Article 368 provides for amendment by special majority, with certain federal provisions additionally requiring ratification by at least half the state legislatures, while a substantial set of provisions can be altered by simple majority.
• Federal in structure, unitary in spirit: the Constitution never uses the word "federation," describing India in Article 1 as a "Union of States," and combines federal features (three Lists, bicameral Parliament, independent judiciary) with strong unitary features (single citizenship, all-India services, emergency provisions, residuary powers with the Union, and Parliament's power under Article 249 to legislate on a State List subject in the national interest).
• Parliamentary government at both levels, with a nominal head of state and a real executive answerable to the legislature — chosen over the presidential model on the reasoning that responsibility to a legislature mattered more than stability of tenure in a country building democratic habits.
• Integrated and independent judiciary: a single judicial hierarchy enforcing both Union and State law, unlike the dual-court structure of American federalism.
• Fundamental Duties (Part IVA, Article 51A), added by the 42nd Amendment on the Swaran Singh Committee's recommendation — non-justiciable, but usable by courts as an interpretive aid.

Common traps UPSC sets here

• Treating the borrowed-features topic as a memorisation list rather than answering the analytical question about whether selective adaptation produced coherence.
• Describing Fundamental Rights and Directive Principles separately when the question asks about their relationship, which has a traceable four-phase history culminating in harmonious construction.
• Citing Kesavananda Bharati without the sequence that produced it — Shankari Prasad, Golaknath, and the post-Kesavananda applications in Indira Nehru Gandhi and Minerva Mills are what demonstrate genuine command.
• Claiming the Supreme Court has defined the basic structure exhaustively — it has deliberately not, developing it case by case, and the criticism of that open-endedness is itself examinable.
• Calling India federal without qualification — Article 1 says "Union of States," and the unitary features are as examinable as the federal ones.

Memory aids

• "1935 gave the structures, 1950 inverted their purpose" — the colonial-inheritance framing.
• "Selective and adapted, not transplanted" — the borrowed-features analytical line.
• "Justiciable Part III, fundamental-in-governance Part IV, harmonised by the courts" — the FR-DPSP relationship.
• "Prasad, Golaknath, Kesavananda, Minerva" — the amendment-power sequence in four names.
• "Amend anything, destroy nothing" — the basic structure doctrine in three words.
• "Union of States, not federation" — the Article 1 precision point.

Exam protocol

• Cite the article number for every constitutional provision referenced, and the case name for every interpretive position.
• For basic structure questions, trace the doctrinal sequence rather than citing Kesavananda in isolation.
• For FR-DPSP questions, present the relationship's evolution across the 42nd and 44th Amendments and the harmonious-construction settlement, not two static descriptions.
• Qualify claims about Indian federalism with the specific unitary features that make it distinctive, using Article 1's own wording.
• Where a question invites criticism of a doctrine or provision, state the criticism at its strongest before answering it — a strawman version of the opposing view weakens the answer that defeats it.
