World Constitutions — Comparative Snapshot — UPSC Polity
The USA & Britain — Presidential vs Parliamentary
🎯 Exam priority: Foundational. Tested occasionally, mostly as quick comparative facts — written vs unwritten, rigid vs flexible, federal vs unitary, and each country's one genuinely unique feature. The exhaustive rights catalogues and article-by-article chapter tables are for reference, not memorisation.
Two constitutions anchor opposite ends of the world's constitutional spectrum — one the oldest written charter still in force, built on strict separation of powers; the other never written down at all, resting instead on centuries of custom and an all-powerful Parliament.
The American Constitution — Written, Rigid, Presidential
Adopted in 1787 at the Philadelphia Convention and in force from 1789, the US Constitution is the oldest written constitution still in force anywhere — barely 12 pages, a Preamble, 7 Articles and 27 Amendments. It is rigid: amendment needs either a two-thirds vote of both Houses of Congress plus ratification by three-fourths of the states within seven years, or a convention called on two-thirds of state legislatures' petition, again ratified by three-fourths of the states — so difficult that only 27 amendments have passed since 1789. The first ten, the Bill of Rights, were added in 1791.
It is federal (50 states plus the District of Columbia, with the Centre's powers enumerated and residuary powers left to the states) and Presidential: the President is both head of state and head of government, elected by an Electoral College of 538 members (270 needed to win) for a fixed four-year term, removable only by impeachment — never once successful, despite five attempts (Andrew Johnson 1868, Richard Nixon 1974, Bill Clinton 1998, and Donald Trump twice, 2019 and 2021). Separation of powers and checks and balances run throughout — the President's "pocket veto" and "qualified veto" over bills, Senate confirmation of top appointments and treaties, and the Supreme Court's power of judicial review over both Congress and the President.
Congress is bicameral: the Senate (100 members, two per state, six-year terms) — the most powerful upper house in the world — and the House of Representatives (435 members, two-year terms).
The British Constitution — Unwritten, Flexible, Parliamentary
Called the "mother of Constitutions," Britain's is unwritten and evolved, not enacted — drawn from five sources: conventions (unwritten political customs, like the monarch always appointing the Commons' majority-party leader as PM), Great Charters (Magna Carta 1215, the Bill of Rights 1689), statutes, common law (judge-made precedent), and legal commentaries (Dicey, Bagehot, Blackstone). It is flexible — Parliament amends it exactly as it makes ordinary law — and unitary, all power resting in a single central government at London.
Government is Parliamentary: the monarch is nominal head of state, the Cabinet (headed by the Prime Minister) is the real executive, collectively responsible to the House of Commons. The single most defining principle is the sovereignty (supremacy) of Parliament — Parliament "can do everything except make a woman a man" (De Lolme) — with the direct consequence that there is no judicial review in Britain: courts cannot strike down an Act of Parliament as unconstitutional. A.V. Dicey's rule of law adds three further pillars: no arbitrary punishment except for a proven breach of law, equal subjection of everyone to the ordinary courts, and citizens' rights flowing from judicial decisions rather than from any written charter.
Parliament is bicameral — the largely hereditary House of Lords (677 members) and the elected House of Commons (659 seats) — and the Cabinet system carries two distinctive institutions: the "Kitchen Cabinet"-style dominance later analysts have called "Prime Ministerial Government," and the officially recognised "Shadow Cabinet," run by the opposition as a ready alternative government.
France & Japan — Hybrid & Post-War Models
Between the American and British poles sit two constitutions that blend elements of both — one deliberately hybrid by design, the other a post-war import that took the British model and gave it a genuinely singular twist.
The French Constitution — Quasi-Presidential, Quasi-Parliamentary
France has changed its constitution roughly every 12 years since the 1789 Revolution; the current one, establishing the Fifth Republic, came into force in 1958 under General de Gaulle's direction, designed for a strong, stable government. It is written (originally 92 Articles across 15 chapters), rigid (a 60% majority vote in both houses, or a Presidential referendum — though the republican form itself can never be amended), and unitary, arguably even more centralised than Britain.
Its government is neither purely Presidential nor Parliamentary but a genuine hybrid: a powerful President, directly elected for a five-year term, sits alongside a Prime Minister-led Council of Ministers that remains responsible to Parliament — yet ministers may not simultaneously be members of Parliament. Parliament itself is deliberately "rationalised" — restricted to legislating only on constitutionally listed subjects, with everything else left to executive decree. A nine-member Constitutional Council reviews laws for constitutionality, but only in an advisory capacity. The bicameral Parliament comprises the dominant National Assembly (577 members, five-year terms) and the Senate (348 members, six-year terms, indirectly elected).
The President is the system's pivot — appointing and chairing the Council of Ministers, commanding the armed forces, negotiating treaties, and holding special emergency powers — removable only through impeachment for high treason. Originally indirectly elected, a 1962 referendum switched to direct election; a further amendment cut the term from seven to five years (2000), and capped the President at two consecutive terms (2008).
The Japanese Constitution — Never Once Amended
Drafted under U.S. General Douglas MacArthur's direction during the post-war Allied Occupation and operative since 1947, the Japanese Constitution — nicknamed both the "MacArthur Constitution" and the "Showa Constitution" — is written (103 Articles, 11 chapters) and rigid (two-thirds of the Diet, then ratification by a popular majority) — yet, remarkably, it has never been amended even once since 1947. It is unitary and adopts the British Parliamentary model, though with real differences: Japan's Prime Minister is chosen by the Diet but formally appointed by the Emperor (not chosen and appointed by the same person, as in Britain), and the PM alone can freely remove Ministers of State.
Japan retains a constitutional monarchy — the Emperor is stripped of all real power, a mere "symbol of the state" deriving that position from the sovereign people, acting only on Cabinet advice. Judicial review exists, as in the US, but with a difference: Japan's Supreme Court derives that power directly and explicitly from the Constitution's own text, unlike America's. A substantial Fundamental Rights chapter (31 of the 103 Articles) is guaranteed as "eternal and inviolate." Japan's single most distinctive feature is Article 9, which renounces war as a sovereign right and bars maintaining land, sea or air forces — Japan is the only modern state to have constitutionally forsworn war altogether, though it maintains "self-defence forces" for its own security. The bicameral Diet comprises the House of Representatives (512 members, four years, more powerful) and the House of Councillors (252 members, six years).
The Socialist & Post-Socialist Models — USSR, Russia & China
Three constitutions built on an explicitly socialist or single-party foundation show how differently a constitution can allocate real power — sometimes to a collective body no other system has ever replicated.
The Soviet Constitution (1977) — The World's First Socialist Charter
Formed after the 1917 Bolshevik Revolution and dissolved in 1989-91, the USSR adopted four constitutions (1918, 1924, 1936 "Stalin," and 1977 "Brezhnev") — the world's first socialist constitution, written and rigid. It was genuinely federal — 15 Union Republics, each with its own constitution and a constitutional right to secede, nested further with autonomous republics/regions/areas within them, earning the USSR the label "Federation of Federations." Government was nominally Parliamentary (a Council of Ministers responsible to the Supreme Soviet), with a bicameral Supreme Soviet (Soviet of the Union and Soviet of the Nationalities, 750 members each, equal powers).
Its single most distinctive institution was the Presidium — a 39-member "collegial" or "plural" executive combining executive, legislative, diplomatic, military and judicial functions at once, described as a genuine "20th-century innovation" no other constitution has replicated. Real power, though, lay with the constitutionally entrenched Communist Party of the Soviet Union (CPSU) — a one-party dictatorship the Constitution itself named the "leading and guiding force" of Soviet society — organised on the principle of "democratic centralism" (elected bodies accountable upward, lower bodies bound by higher ones' decisions). It listed extensive rights (work, rest, health, housing, education) alongside matching duties (labour discipline, defending the "socialist motherland," military service).
Russia (1993) & China (1982) — Two Very Different Successors
Russia, the USSR's largest constituent republic, adopted a wholly new constitution on 20 December 1993 after the Soviet collapse — federal (21 Republics, 6 Territories, 49 Regions, 10 Autonomous Areas, 2 federal cities, plus one Jewish Autonomous Region), explicitly liberal-democratic and multi-party, discarding the old totalitarian system. Its President — directly elected for four years — is genuinely powerful: head of state, head of the executive, and Commander-in-Chief, appointing the Prime Minister and other ministers. A 19-member Constitutional Court reviews the constitutionality of presidential decrees and laws; the bicameral Federal Assembly comprises the Federation Council (178 members) and the State Duma (450 members, four-year terms); impeachment for treason or grave crime needs a two-thirds vote in both Houses.
China's present (fourth) constitution dates to 1982 (after 1954, 1975 and 1978), written and rigid (two-thirds of the National People's Congress, proposed by its Standing Committee or one-fifth of its deputies) and explicitly socialist, naming leadership by the Communist Party of China (CPC) as "the defining feature of socialism with Chinese characteristics." It is unitary and unicameral — the National People's Congress (NPC), roughly 3,000 deputies, is constitutionally the "highest organ of state power." Government is Parliamentary in form (the State Council, headed by a Premier, answers to the NPC) — but China's President is only a ceremonial figure, elected by the NPC for five years, in sharp contrast with Russia's genuinely powerful, directly elected President.
Switzerland — A Third Model Entirely
One constitution refuses to fit either the Presidential or Parliamentary mould at all — instead handing executive power to a genuinely plural, seven-headed body, and giving its own citizens more direct law-making power than almost any democracy on earth.
The Swiss Constitution — A Third Model Entirely
Switzerland's current (third) constitution — after 1848 and 1874 — was adopted in 1999 and took effect on 1 January 2000; written (196 Articles, 6 titles), rigid (with separate procedures for a "total" or "partial" revision, either way needing approval of both the people and the cantons), and federal — 26 cantons (20 full, 6 "half" cantons formed by historic religious/linguistic splits), residuary powers resting with them as in the US.
Its defining feature is the "Council Model" of government — neither Presidential nor Parliamentary. The Federal Council (Bundesrat) is a genuinely plural, seven-member executive elected by the Federal Assembly for four-year terms; its President, elected annually from among the seven, is merely a primus inter pares ("first among equals") with no special powers, comparable to neither a British PM nor an American President. Council members act both collectively (making executive decisions together) and individually (each heading a department); they can be removed neither by a no-confidence vote nor by impeachment.
Parliament — the Federal Assembly — is bicameral: the Council of States (46 members, two per full canton, one per half canton, echoing the American Senate's equal-per-unit design) and the National Council (200 members, directly elected by proportional representation). Uniquely among the world's legislatures, the two chambers hold exactly equal power — no other bicameral system gives its upper house powers identical to its lower house.
Switzerland practises genuine direct democracy through mandatory and optional referendums (constitutional amendments must always go to a popular vote) and the citizen-driven initiative (100,000 voters can force a constitutional revision to a vote). And its citizenship is uniquely three-fold — of the commune (municipality) first, then the canton, then the federation — with communal citizenship regarded as the most fundamental of the three.
Comparative Snapshot — All Eight Systems at a Glance
Laid side by side, these eight constitutional systems reveal just how many genuinely different answers the world has found to the same basic questions — who writes the rules, how hard are they to change, and who actually wields executive power.

USA | 1787 / in force 1789 | Written | Rigid | Federal | Presidential | Bicameral (Senate + House of Representatives) |
Britain | Uncodified, evolved | Unwritten | Flexible | Unitary | Parliamentary (constitutional monarchy) | Bicameral (Lords + Commons) |
France | 1958 (Fifth Republic) | Written | Rigid | Unitary | Quasi-Presidential / quasi-Parliamentary | Bicameral (National Assembly + Senate) |
Japan | 1947 | Written | Rigid (never amended) | Unitary | Parliamentary (constitutional monarchy) | Bicameral (Representatives + Councillors) |
USSR (historical) | 1977 (fourth) | Written | Rigid | Federal (with a right to secede) | One-party socialist; Presidium as collegial head of state | Bicameral (Soviet of Union + Nationalities) |

Why UPSC Asks This
The classic pairwise contrasts are the highest-yield facts: written vs unwritten (USA vs Britain), rigid vs flexible, federal vs unitary, and judicial review present vs absent (Britain uniquely has none).
Each country's single most distinctive feature is disproportionately tested — Japan's zero amendments and Article 9, the USSR's Presidium, Switzerland's Council Model and equal-power bicameralism.
Don't confuse China's ceremonial President with Russia's genuinely powerful one — both are called "President," but their real authority is opposite.
