Comparative Constitutional Law
Comparative constitutional law studies the structures and operation of different constitutional systems to illuminate principles, draw lessons and locate one's own constitutional order. For CSS candidates, the standard comparison set is the United States, United Kingdom, France, India and Pakistan.
A field of legal study that systematically compares constitutional texts, institutions and judicial doctrines across jurisdictions. K.C. Wheare's "Modern Constitutions" (1951) and Mauro Cappelletti's "Judicial Review in Contemporary World" (1971) are classic introductions.
Classification of constitutions
Constitutions may be classified along several axes:
- Written (USA 1787, India 1950, Pakistan 1973) vs. Unwritten (UK).
- Rigid (USA — Art. V super-majority) vs. Flexible (UK — ordinary statute).
- Federal (USA, India, Pakistan, Germany) vs. Unitary (UK, France, Japan).
- Republican (USA, France, India, Pakistan) vs. Monarchical (UK, Spain, Japan).
- Presidential (USA) vs. Parliamentary (UK, India, Pakistan) vs. Semi-presidential (France, Russia).
The United States — 1787
The world's oldest written constitution, drafted at the Philadelphia Convention 1787. Salient features:
- Federal dual-list with residual powers in the states (10th Amendment).
- Strict separation of powers — Congress (Art. I), President (Art. II), Judiciary (Art. III).
- Checks and balances — vetoes, impeachment, judicial review (Marbury v. Madison, 1803).
- Bill of Rights — first ten amendments (1791).
- Presidential system — directly elected by Electoral College.
The United Kingdom — Uncodified
The UK has no single document. Its constitution comprises:
- Statutes (Magna Carta 1215, Bill of Rights 1689, Parliament Acts 1911/1949, Human Rights Act 1998, Constitutional Reform Act 2005, European Union (Withdrawal) Act 2018).
- Common law (Entick v. Carrington, Anisminic Ltd. v. FCC).
- Conventions (cabinet collective responsibility, royal assent).
- Treatises (Dicey, Introduction to the Study of the Law of the Constitution, 1885).
The doctrines of parliamentary sovereignty and rule of law (Dicey's three meanings) are constitutional bedrock. The Supreme Court of the UK (created 2009) replaced the Appellate Committee of the House of Lords.
- Parliamentary sovereignty: Parliament can make or unmake any law (Dicey).
- Rule of law: (i) supremacy of regular law; (ii) equality before law; (iii) rights derive from courts, not abstract declarations.
- No separation of powers in the strict sense; fusion of executive and legislature.
- Constitutional conventions are politically binding but not legally enforceable (R (Miller) v. Secretary of State for Exiting the EU [2017]).
France — Fifth Republic 1958
Drafted under Charles de Gaulle, the 1958 Constitution created a semi-presidential system:
- President directly elected for five years (revised 2000); appoints the PM.
- Prime Minister heads the government and is responsible to the National Assembly.
- Bicameral Parliament — National Assembly + Senate.
- Constitutional Council (Conseil constitutionnel) performs a priori and (since 2008 reform) a posteriori review (QPC — question prioritaire de constitutionnalité).
- Declaration of the Rights of Man and of the Citizen 1789 enjoys constitutional status (preamble).
India — 1950
The longest written constitution in the world (450+ articles, 12 schedules). Distinctive features:
- Quasi-federal with strong Centre — three lists (Union, State, Concurrent).
- Parliamentary system with elected President (Article 54).
- Fundamental Rights (Part III) and Directive Principles (Part IV).
- Basic Structure Doctrine — Kesavananda Bharati (1973).
- Single integrated judiciary under the Supreme Court.
- Article 32 — fundamental right to constitutional remedies (Ambedkar's "heart and soul").
Pakistan — 1973
Pakistan's third constitution and the longest-surviving:
- Federal parliamentary republic with Islamic provisions.
- Bicameral Parliament — Senate + National Assembly.
- Fundamental Rights (Arts. 8–28) with enforcement via Arts. 184(3) and 199.
- Council of Common Interests for federalism.
- Federal Shariat Court for Islamic review (Art. 203D).
- Objectives Resolution (Art. 2A) as substantive provision.
For a CSS comparative question, use a four-column framework: (1) form of state and government; (2) source/nature of constitution; (3) protection of rights and judicial review; (4) federal/unitary structure. Always close with a critical comment on relative effectiveness — e.g. Pakistan's parliamentary federalism vs. India's stronger Centre vs. US dual federalism.
Comparative table
| Feature | USA | UK | France | India | Pakistan |
|---|---|---|---|---|---|
| Constitution type | Written, rigid | Unwritten, flexible | Written, rigid | Written, semi-rigid | Written, rigid |
| Form of state | Federal | Unitary (devolved) | Unitary | Quasi-federal | Federal |
| Head of state | Elected President | Hereditary Monarch | Elected President | Elected President | Elected President |
| System of govt. | Presidential | Parliamentary | Semi-presidential | Parliamentary | Parliamentary |
| Judicial review | Marbury v. Madison (1803) | Limited (HRA 1998) | Conseil constitutionnel | SC under Art. 32/226 | SC under Art. 184(3)/199 |
| Bill of rights | First 10 Amendments | HRA 1998 (incorporates ECHR) | DDHC 1789 | Part III | Articles 8–28 |
| Amendment | Super-majority Art. V | Ordinary statute | Articles 89, 11 | Article 368 (three procedures) | Article 239 |
Themes for analysis
- Federalism: dual (USA, Germany) vs. cooperative (India, Pakistan post-18th Amendment) vs. devolved (UK).
- Separation of powers: strict (USA), partial (France), fused (UK, India, Pakistan).
- Judicial review: decentralised (USA) vs. centralised constitutional court (France, Germany) vs. hybrid (India, Pakistan).
- Rights protection: entrenched (USA, India, Pakistan) vs. statutory (UK).
- Constitutional amendment: classified by Bryce as "flexible" or "rigid"; degree of difficulty correlates with constitutional stability.
