Show answer

Answer: (C) Both 1 and 2

Statement 1 is correct:

In Britain, Parliament is sovereign — no written constitution limits its law-making power.

In India, Parliament's power is limited by the Constitution, and laws violating it can be struck down through judicial review.

Statement 2 is correct:

India has the Constitution Bench in the Supreme Court (Articles 143 and 145(3)) — at least 5 judges constituted by the CJI to decide substantial constitutional questions.

This has no British equivalent.

Both are correct.

Answer: (c).

Why this was asked

Parliamentary sovereignty means the British Parliament can make or unmake any law without constitutional limits, while the Indian Parliament operates under constitutional constraints with judicial review.

India's Constitution Bench system allows the Supreme Court to refer substantial constitutional questions to a bench of at least 5 judges, a mechanism that does not exist in the British system.

The question tests understanding of how India modified the Westminster model by adding written constitutional supremacy and specialized constitutional adjudication.

Parliamentary Sovereignty: Britain vs India

Indian Polity British Parliament is supreme power of the Parliament to legislate is limited

Parliamentary Sovereignty: British Model vs Indian Adaptation

Must know

British Parliament is supreme — no written constitution limits its power

Indian Parliament is limited by the Constitution and judicial review

India adopted constitutional supremacy over parliamentary supremacy

Good to know

Judicial review allows Indian courts to strike down unconstitutional laws

India adopted the Westminster parliamentary model but made one crucial change — constitutional supremacy replaced parliamentary sovereignty. This fundamental shift defines how laws are made and challenged in both systems.

Key Differences

Aspect

Britain

India

Constitution

Unwritten, flexible

Written, rigid

Parliament's Power

Supreme, unlimited

Limited by Constitution

Judicial Review

No power to strike down laws

Can declare laws unconstitutional

Constitutional Amendment

Simple majority

Special procedure (Article 368)

Higher Law

Parliament's will

Constitution

Question Anchoring

Statement 1 tests this core difference — British MPs can pass any law without constitutional limits, while Article 13 and judicial review constrain Indian Parliament's legislative power.

Exam traps

Trap: Assuming India copied Britain's model completely — we adopted structure but changed power distribution

Trap: Confusing parliamentary system (government formation) with parliamentary sovereignty (unlimited law-making power)

Remember: India has constitutional supremacy, Britain has parliamentary supremacy

Constitution Bench of Supreme Court

Indian Polity Constitution Bench Supreme Court

Constitution Bench: India's Unique Constitutional Court

Must know

Minimum 5 judges constitute a Constitution Bench

CJI decides composition and refers constitutional questions

No equivalent exists in British judicial system

Good to know

Articles 143 & 145(3) provide the constitutional basis

The Constitution Bench is India's specialized mechanism for resolving major constitutional questions — a feature absent in Britain's legal system. Article 145(3) mandates at least 5 judges for substantial constitutional matters.

Key Features

Chief Justice constitutes the bench and decides which cases need constitutional interpretation

Handles constitutional amendments, fundamental rights disputes, and federal questions

Binding precedent — decisions apply to all lower courts across India

Can be constituted ad hoc or as a regular bench depending on case load

Article 143 allows President to seek advisory opinions from Constitution Bench

Question Anchoring

Statement 2 highlights this uniquely Indian institution — Britain's House of Lords (highest court) has no specialized constitutional bench structure like India's Article 145(3) system.

Exam traps

Trap: Minimum judge requirement — it's 5 judges minimum, not exactly 5

Trap: Assuming Britain has similar system — UK has no written constitution so no Constitution Bench needed

Remember: CJI decides composition, not automatic referral for all constitutional cases

Judicial Review in India

Indian Polity constitutionality Amendment Act of the Parliament

Judicial Review: India's Constitutional Safeguard

Must know

Article 13 empowers courts to strike down unconstitutional laws

Parliament and state laws both subject to judicial review

Basic Structure Doctrine limits even constitutional amendments

Good to know

Supreme Court is final arbiter of constitutional interpretation

Judicial review allows Indian courts to examine whether laws violate the Constitution. Article 13 declares that any law inconsistent with Part III (Fundamental Rights) is void — a power that distinguishes India from Britain.

Scope & Limitations

Constitutional amendments also subject to review under Basic Structure Doctrine (Kesavananda Bharati, 1973)

Ordinary laws can be struck down if they violate any constitutional provision

State laws subject to review by High Courts and Supreme Court

Executive actions also reviewable if they exceed constitutional authority

Exam traps

Trap: Thinking judicial review only applies to ordinary laws — constitutional amendments also reviewable since 1973

Trap: Confusing with judicial activism — review is about constitutional compliance, not policy preferences

Remember: Article 13 specifically mentions Part III violations but courts review entire Constitution

Written vs Unwritten Constitution

Indian Polity British model

Written vs Unwritten Constitution: Fundamental Difference

Must know

Britain has unwritten constitution based on conventions and precedents

India has written constitution — world's longest

Good to know

Written constitutions provide legal certainty and judicial review

Unwritten systems offer flexibility but less legal protection

The written vs unwritten distinction determines how constitutional principles are established, interpreted, and changed. This choice shapes the entire legal and political system.

Exam traps

Trap: Britain has some written laws but no single constitutional document

Trap: Unwritten ≠ unrecorded — Britain's constitutional principles are documented but scattered

Remember: New Zealand, Israel also have unwritten constitutions — not just Britain
