Comparing Constitutions: India, the United States and Britain

No constitution is written in a vacuum, and India's least of all. The Constituent Assembly studied the American, British, Irish, Canadian and French systems before choosing what to borrow and what to reject. The result is a constitution that looks parliamentary like Britain, federal like America, and republican like France, yet behaves like none of them. UPSC asks this comparison almost every year, because the contrasts reveal what is distinctive about the Indian design.

Why India studied the world before writing its own

The framers were comparative constitutionalists by necessity. Constitutional adviser B.N. Rau toured the United States, Canada, Ireland and Britain before drafting. The borrowing was deliberate and selective. From Britain came parliamentary government, the rule of law, legislative procedure, single citizenship, the cabinet system, prerogative writs, parliamentary privileges and bicameralism. From the United States came fundamental rights, the independence of the judiciary, judicial review, the impeachment of the President, the removal of Supreme Court and High Court judges, and the office of the Vice-President. From Ireland came the Directive Principles of State Policy, the nomination of members to the Rajya Sabha and the method of electing the President. From Canada came the federation with a strong centre, residuary powers vesting in the centre, and the appointment of governors. From Australia came the Concurrent List and the joint sitting; from Weimar Germany, emergency suspension of fundamental rights; from the USSR, fundamental duties; from France, liberty, equality, fraternity; from South Africa, the amendment procedure; from Japan, procedure established by law. The art was in the adaptation: nothing was copied without being Indianised.

Written versus unwritten: the longest constitution and the one that isn't

The Indian Constitution is written, codified and the lengthiest in the world, originally 395 articles in 22 parts. The British constitution is unwritten and uncodified, a mix of statutes, common law, conventions and works of authority like Magna Carta (1215) and the Bill of Rights (1689). In India the Constitution is supreme; in Britain Parliament is supreme and no court can invalidate an Act of Parliament. Britain has no codified bill of rights; India entrenches fundamental rights in Part III for direct court enforcement. The unwritten constitution also explains British flexibility: what India would call a constitutional amendment, Britain achieves through an ordinary Act of Parliament.

Parliamentary versus presidential: where the real executive sits

This is the most examined contrast in the chapter. India runs a parliamentary system: the President is the nominal head of state while the Prime Minister is the real head of government, the Council of Ministers must be members of Parliament, and the cabinet is collectively responsible to the Lok Sabha under Article 75. The United States runs a presidential system: the President is both head of state and government, strictly separated from Congress, and not responsible to the legislature. India's President is elected indirectly by MPs and MLAs with no term limit; America's is chosen via the electoral college and limited to two terms by the 22nd Amendment. The Indian President's veto is suspensive: if Parliament passes a returned bill again, assent must follow. The American veto is qualified: Congress can override it only with a two-thirds majority in both Houses. In emergencies the contrast sharpens: the Indian President can proclaim national, state and financial emergencies under Articles 352, 356 and 360, while the American President relies on inherent powers plus congressional authorisation.

Federal versus unitary: holding together and coming together

Both are federations with written constitutions and dual polities, but built in opposite directions. The United States is a coming-together federation: thirteen sovereign colonies agreed to form a union, so the states retain everything not given to the centre, residuary powers vest in the states, each state has its own constitution, and citizens hold dual citizenship of the nation and their state. India is a holding-together federation: a unified country was divided into states by the Centre, so Parliament can alter state boundaries without state consent under Article 3, residuary powers vest in the Union under Entry 97 of the Union List, there is a single constitution and single citizenship, and the Centre can dismiss state governments under Articles 352 and 356, a power no American President possesses. Britain, meanwhile, is unitary: Parliament's authority extends uniformly, devolution to Scotland, Wales and Northern Ireland exists at Westminster's pleasure.

Rigid versus flexible: how each constitution changes itself

The Indian Constitution is a blend: some provisions amend by simple majority, some by special majority, and federal provisions by special majority plus ratification by half the states under Article 368. The American Constitution is rigid: amendments need two-thirds of Congress and ratification by three-fourths of the states, which is why it has only 27 amendments in over two centuries. Britain is flexible: Parliament amends constitutional law through the ordinary legislative process. Kesavananda Bharati (1973) lets Indian courts strike down amendments violating the basic structure, a power no American or British court holds. France sits between: a written rigid constitution with a directly elected President holding real powers in defence and foreign policy.

Sovereignty of Parliament versus supremacy of the Constitution

A.V. Dicey's doctrine of parliamentary sovereignty, Parliament can make or unmake any law, remains the operating theory in Britain: courts may declare legislation incompatible with human rights, but they cannot invalidate it. India's position, tested in the 2023 mains question comparing British and Indian approaches, is the opposite: parliamentary sovereignty in India is subject to constitutional limitations and judicial review. Parliament is supreme within its sphere, but the Constitution is supreme over Parliament. India's Speaker keeps party membership; Britain follows the convention of once a Speaker, always a Speaker. Privileges flow from Article 105 in India, subject to fundamental-rights review; in Britain they rest on parliamentary custom and courts stay out.

Rights and courts: who guards what

India's Part III guarantees enforceable fundamental rights, with Article 32 allowing direct access to the Supreme Court. America's Bill of Rights plays the same role, with Marbury v. Madison (1803) establishing judicial review. Britain relies on common law and the Human Rights Act, 1998. India has a single integrated judiciary, with Article 141 making Supreme Court law binding on all courts. The United States has a dual system of federal and state courts. Britain's Supreme Court interprets the separate legal systems of England and Wales, Scotland and Northern Ireland. Appointments diverge: India's collegium, America's presidential nomination with Senate confirmation, Britain's Judicial Appointments Commission with lay members. India allows liberal public interest litigation with relaxed locus standi; the United States demands concrete injury; Britain requires sufficient interest. India guarantees life and liberty by procedure established by law (Article 21); the American 5th and 14th Amendments promise due process, a wider guarantee Indian courts have partly read into Article 21 since Maneka Gandhi (1978).

Three models of secularism

Secularism is where comparison becomes philosophy. India practises positive secularism: the state has no official religion, treats all religions with equal respect, and may intervene to reform them, as with temple entry laws and the abolition of untouchability, under Articles 25 to 28. Analysts call this principled distance: a three-fold strategy of state neutrality and equal treatment of all religions, non-interference in religious practice, and selective intervention against practices that violate equality, dignity or justice. Secularism was declared part of the basic structure in Kesavananda Bharati (1973), and in S.R. Bommai v. Union of India (1994) the Court held that a state government acting against secular principles could be dismissed. The United States practises neutral secularism: the First Amendment mandates strict church-state separation. France practises laicite, a stricter separation still: religion is treated as a purely private affair, religious symbols are banned in public schools, and the state does not recognise religious minorities the way Articles 29 and 30 of the Indian Constitution do. UPSC has mined this seam repeatedly, including the 2024 question asking what France can learn from India's approach to secularism.

France: the semi-presidential republic

France offers the sharpest contrast of the four, because it mixes what the others keep separate. The Fifth Republic, founded in 1958, is unitary rather than federal, and runs a semi-presidential system: a directly elected President with real powers shares the executive with a Prime Minister answerable to Parliament. India borrowed the republican ideals of liberty, equality and fraternity from the French Revolution, but rejected the French executive model in favour of parliamentary government.

Two French ideas travel poorly but test well in exams. Cohabitation is the division of functions, not of power: when the President and the parliamentary majority come from opposite camps, the President keeps foreign affairs and defence while the Prime Minister runs day-to-day administration. Laicite is stricter than Indian secularism: the state neither supports religious activity nor permits its visible symbols in public schools and offices, leaving no room for the state-sponsored religious reform that the Indian Constitution permits.

Japan: the parliamentary monarchy India partially mirrors

Japan is the quietest comparison and a favourite Prelims trap. Its Constitution creates a parliamentary government under a unitary state, with the Emperor as the symbol of the State and of the unity of the people, performing only ceremonial duties. The Diet, Japan's bicameral legislature of the House of Representatives and the House of Councillors, designates the Prime Minister, whom the Emperor then appoints; ministers must be civilians and Diet members. India borrowed the phrase procedure established by law from Japan, and the two systems converge on judicial appointments, where both insulate judges with fixed retirement ages and difficult removal procedures.

Four constitutions at a glance

The table below compresses the whole comparison into one revision sheet:

Prelims hooks

• Britain: parliamentary government, rule of law, cabinet system, single citizenship, prerogative writs, bicameralism.
• USA: fundamental rights, judicial review, independence of judiciary, impeachment of President, Vice-President's office.
• Ireland: Directive Principles, nomination of Rajya Sabha members, method of presidential election.
• Canada: federation with strong centre, residuary powers with the centre, appointment of governors.
• Australia: Concurrent List, freedom of trade and commerce, joint sitting of Parliament.
• Basic structure doctrine (Kesavananda Bharati, 1973) lets Indian courts strike down constitutional amendments; no such power exists in the US or UK.

Mains angle

A comparison question is an invitation to show what makes India distinctive. Never list similarities and differences mechanically; organise around an argument. For parliamentary versus presidential, argue India chose accountability over stability: collective responsibility keeps the executive answerable daily, at the cost of America's fixed-term stability. For federalism, argue that holding-together federalism explains both Article 3 and Article 356: the Centre's extraordinary powers are the price of keeping a diverse union intact.

For sovereignty, the thesis writes itself: Britain trusts Parliament, America trusts the people through a rigid constitution, India trusts the Constitution as interpreted by courts. Anchor each claim in a case: Kesavananda for basic structure, Bommai for secularism, Maneka Gandhi for Article 21, and close by noting the framers borrowed everything and copied nothing.

Key Terms

• special majority plus ratification: Special majority plus ratification is the toughest Article 368 amendment procedure: the amendment needs a special majority in Parliament (majority of total membership plus two-thirds present and voting) and, because it touches federal provisions such as the Seventh Schedule or state representation, ratification by at least half of the state legislatures. It matters for UPSC because it is the standard test for identifying amendments that alter Centre-State relations, a favourite mains theme. The 101st Constitutional Amendment (GST, 2016), ratified by the states before assent.
• Human Rights Act, 1998: The Human Rights Act, 1998 is the United Kingdom's statute incorporating the European Convention on Human Rights into domestic law. It requires UK courts to interpret legislation compatibly with Convention rights and lets them issue declarations of incompatibility when statutes conflict. For UPSC's comparative constitutionalism it shows a middle path between parliamentary sovereignty and entrenched rights, unlike India's directly enforceable fundamental rights. Frequently asked in comparing-constitutions questions. UK courts used it to reshape counter-terror detention powers after the Belmarsh ruling on indefinite detention.
• Judicial Appointments Commission: The Judicial Appointments Commission is Britain's independent body for selecting judges, established in April 2006 under the Constitutional Reform Act 2005. It selects judges for England and Wales on merit through panels that include lay commissioners, taking over the appointments role once held by the Lord Chancellor. For UPSC, it is the contrast point: India's own NJAC under the 99th Amendment was struck down in 2015, so India retains the collegium system.
• basic structure doctrine: Basic structure doctrine is the constitutional principle laid down in Kesavananda Bharati (1973) that Parliament may amend the Constitution under Article 368 but cannot destroy its basic structure. Features like supremacy of the Constitution, rule of law, judicial review, and federalism are beyond amendment. For UPSC mains, it is the central doctrine in any answer on the balance between Parliament's amending power and constitutional limits. Kesavananda Bharati v. State of Kerala, Supreme Court, 1973
• separation of powers: Separation of powers is the doctrine, articulated by Montesquieu, that liberty is protected when legislative, executive and judicial functions are vested in distinct organs that check one another. India adopts it partially: functional separation exists, but with overlaps like judicial review. UPSC significance: GS-2, the Indian Constitution and polity. Montesquieu's The Spirit of Laws (1748)
• Bill of Rights: The Bill of Rights is the first ten amendments to the United States Constitution, ratified in 1791, guaranteeing fundamental liberties such as freedom of speech, religion and the press, protection against unreasonable searches, and due process of law. It became the model for written guarantees of individual rights in modern constitutions. For UPSC, it is important in comparative constitutionalism, as India's Fundamental Rights drew directly on this tradition. the first ten amendments to the US Constitution, ratified in 1791
• rule of law: The rule of law is the principle that everyone, including the state, is subject to publicly known laws applied equally, with no one above the law. Formulated by A.V. Dicey as supremacy of law, equality before law and constitutionalism, it underpins Article 14 in India. It matters for UPSC because it is a foundational GS-2 concept, invoked in mains answers on governance, judicial review and protection against arbitrary state action. Article 14 of the Indian Constitution
• collective responsibility: Collective responsibility is the constitutional doctrine, under Article 75(3), that the Council of Ministers is collectively responsible to the Lok Sabha, meaning the whole ministry stands or falls together on the government's policies. Its features are cabinet solidarity and joint accountability. It matters for UPSC because prelims tests Article 75(3) and mains links it to no-confidence motions and parliamentary accountability. the Vajpayee government's defeat in the 1999 confidence vote
• Constituent Assembly: The Constituent Assembly was the body that framed India's Constitution, constituted under the Cabinet Mission Plan of 1946 with 389 members drawn from provinces, princely states, and chief commissioners' provinces. It met first on 9 December 1946 under Sachchidanand Sinha, with Rajendra Prasad as permanent president, and adopted the Constitution on 26 November 1949. For UPSC, it is the foundation of Indian constitutional history and polity. Jawaharlal Nehru moved the Objectives Resolution on 13 December 1946, setting the Assembly's guiding principles.
• Directive Principles: The Directive Principles of State Policy are the non-justiciable guidelines in Part IV (Articles 36 to 51) of the Indian Constitution that direct the state toward social and economic justice. Borrowed from the Irish Constitution, they are fundamental to governance but unenforceable in courts. For UPSC, the tension and harmony between them and Fundamental Rights is a recurring mains theme. In Minerva Mills v. Union of India (1980), the Supreme Court held that the Constitution balances Fundamental Rights with Directive Principles.
• Indian Constitution: The Indian Constitution is the supreme law of India, adopted by the Constituent Assembly on 26 November 1949 and brought into force on 26 January 1950. It is the world's longest written constitution, blending parliamentary democracy, fundamental rights, directive principles and federalism with a strong centre. Drafted under B.R. Ambedkar's chairmanship of the Drafting Committee, it draws on the Government of India Act, 1935 and several foreign constitutions. For UPSC, it is the foundation of the entire polity syllabus.
• Kesavananda Bharati: Kesavananda Bharati was the head seer of the Edneer Mutt in Kasaragod, Kerala, who filed the 1970 writ petition challenging Kerala's land reform laws that became the landmark Kesavananda Bharati case. His thirteen-judge challenge produced the basic structure doctrine, and he died in September 2020. He matters for every GS-2 polity discussion of constitutional limits on Parliament's power to amend the Constitution. The Edneer Mutt seer who petitioned the Supreme Court in 1970
