The Supreme Court has played a major role in defining the powers, limitations and constitutional position of State Legislatures.
Important judgments have clarified:
For UPSC, these judgments should be studied not as isolated cases but as:
Case → Constitutional Issue → Principle → Significance
The case concerned:
Article 356
and the dismissal of State Governments / dissolution of State Legislative Assemblies.
The Court examined the constitutional validity of the use of President's Rule in States.
The judgment had major implications for:
The Supreme Court held that:
The judgment significantly restricted arbitrary use of Article 356. :contentReference[oaicite:0]{index=0}
Remember:
Bommai → Article 356 + Floor Test + Federalism + Judicial Review
The case concerned:
Dissolution of the Bihar Legislative Assembly
under Article 356.
The Supreme Court held the proclamation dissolving the Bihar Assembly to be:
Unconstitutional
Although the Court did not restore the Assembly because of the changed factual circumstances, the judgment reinforced that constitutional powers relating to dissolution are subject to judicial scrutiny. :contentReference[oaicite:1]{index=1}
The case is important for:
Memory:
Rameshwar Prasad → Bihar Assembly Dissolution
The case involved:
Governor's powers relating to the State Legislative Assembly
and the relationship between:
The Governor advanced the Assembly session without following the normal constitutional process based on ministerial advice.
The issue involved the constitutional scope of gubernatorial discretion.
The Supreme Court placed significant limits on the Governor's power in relation to legislative proceedings and held that the Governor could not ordinarily interfere with the functioning of the Assembly in the manner involved in the case. :contentReference[oaicite:2]{index=2}
Important for:
Governor + Legislative Assembly + Article 174 + Federalism
Memory:
Nabam Rebia → Governor cannot arbitrarily control Assembly proceedings
The case concerned:
Tenth Schedule
and the:
Anti-Defection Law
The Supreme Court:
The judgment directly concerns disqualification of members of Parliament and State Legislatures under the Tenth Schedule. :contentReference[oaicite:3]{index=3}
Remember:
Kihoto Hollohan → Tenth Schedule + Speaker + Judicial Review
The case concerned:
Delay in deciding Anti-Defection petitions
by the Speaker.
The Supreme Court emphasised that disqualification petitions under the Tenth Schedule should not be kept pending indefinitely and recognised the need for timely adjudication.
The case became an important authority on:
Speaker's delay + Tenth Schedule + Judicial Review
The matter arose from prolonged inaction by the Manipur Speaker. :contentReference[oaicite:4]{index=4}
Memory:
Keisham Meghachandra → Delay in Defection Cases
The case arose from the:
Maharashtra political crisis
and involved:
The Supreme Court specifically identified constitutional questions relating to the interpretation of the Tenth Schedule and the powers of the Speaker and Governor. :contentReference[oaicite:5]{index=5}
The judgment examined:
Remember:
Subhash Desai → Maharashtra Crisis + Governor + Speaker + Tenth Schedule
The case involved:
Legislative Privilege
and the Punjab Legislative Assembly's action against former Chief Minister Amarinder Singh.
The Supreme Court held that the Assembly had exceeded its privilege powers because the alleged conduct did not constitute a valid breach of legislative privilege in the circumstances.
The case demonstrates that:
Legislative Privilege is not unlimited.
Courts can scrutinise the exercise of privilege where constitutional or jurisdictional limits are crossed. :contentReference[oaicite:6]{index=6}
Important for:
Memory:
Amarinder Singh → State Legislative Privilege + Judicial Review
The case concerned the conflict between:
Legislative Privilege
and:
Judicial Power
The controversy arose after the Uttar Pradesh Legislative Assembly acted against Keshav Singh for alleged breach of privilege.
The case established that:
Remember:
Keshav Singh → Legislative Privilege + Judiciary
The case concerned:
Legislative Privilege + Freedom of Speech and Publication
The dispute involved publication of legislative proceedings and the relationship between:
The judgment is an important early authority on the constitutional relationship between:
Legislative Privilege
and:
Fundamental Rights
It demonstrates that legislative privilege has a special constitutional character.
Memory:
M.S.M. Sharma → Privilege + Freedom of Speech/Publication
The case primarily concerned:
Parliamentary Privilege
but its principles are highly relevant to State Legislative Privileges under Article 194.
The Supreme Court recognised that:
Legislative Privileges are not completely immune from Judicial Review
Courts may examine serious constitutional or legal defects in the exercise of privilege.
Though it concerned Parliament, the judgment is important for understanding:
Article 194 + Judicial Review of State Legislative Privilege
The case concerned:
Article 254
and:
Repugnancy between State and Union laws
on matters in the Concurrent List.
The Court explained that:
The Supreme Court has continued to rely on these principles in later repugnancy cases. :contentReference[oaicite:7]{index=7}
Memory:
M. Karunanidhi → Article 254 + Repugnancy
The case concerned:
Legislative competence + Repugnancy + Taxation
The Court clarified the constitutional distribution of legislative fields and explained the operation of Article 254.
Repugnancy arises only when:
Both legislatures are competent to legislate in the same field
particularly in the Concurrent List context. :contentReference[oaicite:8]{index=8}
Important for:
Legislative Competence + Concurrent List + Article 254
Memory:
Hoechst → Legislative Field + Repugnancy
A large body of Supreme Court jurisprudence has developed around:
Legislative Competence
The Court applies principles such as:
The key principle is:
State Legislature can legislate only within its constitutional field.
Recent Supreme Court judgments continue to reaffirm that a law beyond legislative competence is constitutionally invalid. :contentReference[oaicite:9]{index=9}
The doctrine was developed through several constitutional cases and is repeatedly applied by the Supreme Court.
The Court examines the:
True Nature and Character
of the legislation rather than merely its form or incidental effects.
If the legislation substantially falls within the Legislature's competence, incidental encroachment into another field does not automatically invalidate it.
Memory:
Pith and Substance → True Nature of Law
The doctrine prevents a Legislature from doing indirectly what it cannot do directly.
The principle is:
What cannot be done directly cannot be done indirectly.
If a State Legislature lacks competence over a subject, it cannot disguise legislation on that subject under an apparently valid legislative entry.
Memory:
Colourable Legislation → Constitutional Competence
The case established the:
Basic Structure Doctrine
Although not exclusively about State Legislatures, it is essential for understanding the constitutional limits within which State legislation operates.
The judgment established that:
The Constitution is supreme
and constitutional amendments cannot destroy its basic structure.
Ordinary State legislation must remain within:
Memory:
Kesavananda → Basic Structure
The case reinforced:
Limited Government + Judicial Review + Constitutional Supremacy
It is relevant to State Legislatures because it reinforces that constitutional power is:
Limited, not Absolute
Memory:
Minerva Mills → Limited Power + Judicial Review
The Supreme Court has consistently treated legislative privilege as:
Constitutionally Protected but Not Unlimited
Important cases include:
The broad principle is:
Legislative Privilege + Constitutional Limits + Judicial Review
Important cases include:
These cases establish that:
Important cases include:
The broad constitutional principles are:
Speaker → Initial Decision
Judicial Review → Available
Delay → Constitutionally Problematic
Party Direction → Relevant to Tenth Schedule
The relationship between the Governor and State Legislature concerning Bills has become an important area of recent Supreme Court constitutional jurisprudence.
The Supreme Court's Constitution Bench decision in November 2025 considered:
Article 200
and clarified the constitutional options available to the Governor when a Bill is presented for assent.
The Court addressed:
For current UPSC preparation, this topic should be studied separately as a:
Governor + State Legislature + Article 200
issue.
The Supreme Court's official records show a Constitution Bench proceeding in November 2025 concerning this Article 200 controversy. :contentReference[oaicite:10]{index=10}

31. Mains Perspective
Supreme Court judgments have played a crucial role in defining the constitutional boundaries of State Legislatures.
They have generally reinforced four principles:
Constitutional Supremacy
State Legislatures are subject to the Constitution.
Federal Balance
The Union cannot arbitrarily destroy State legislative autonomy.
Judicial Review
Legislative and executive actions remain subject to constitutional scrutiny.
Responsible Government
Majority questions should ordinarily be resolved on the floor of the House.
The case-law therefore demonstrates that:
State Legislative Power is Democratic but Constitutionally Limited
32. Significance
The Supreme Court's jurisprudence has:
Protected State autonomy
Restricted misuse of Article 356
Strengthened floor tests
Controlled arbitrary gubernatorial action
Regulated Anti-Defection adjudication
Protected legislative privilege while recognising constitutional limits
Clarified Union-State legislative conflicts
Strengthened judicial review
Thus:
Judicial Review + Federalism + Legislative Democracy
form the core of this jurisprudence.
33. Case-Law as Constitutional Checks and Balances
The major judgments can be understood as a system of checks:
Governor
↓
Judicial Review
↓
Bommai / Nabam Rebia
Speaker
↓
Judicial Review
↓
Kihoto / Keisham / Subhash Desai
Legislature
↓
Constitutional Limits
↓
Privilege Cases
State Law
↓
Judicial Review
↓
Article 254 / Legislative Competence Cases
This prevents any one constitutional institution from exercising unlimited power.
34. Reform Perspective
The lessons from these judgments suggest several institutional reforms:
Time-Bound Defection Decisions
Reduce uncertainty caused by prolonged Speaker inaction.
Clearer Governor Conventions
Majority should ordinarily be tested on the floor.
Better Legislative Privilege Rules
Privileges should be clear enough to avoid unnecessary constitutional conflict.
Stronger Legislative Drafting
Clearer laws can reduce disputes over competence and repugnancy.
Better Centre-State Dialogue
Federal conflicts should be addressed through constitutional consultation where possible.
35. Conclusion
Important Supreme Court judgments have shaped the constitutional position of State Legislatures in four major areas:
Governor and Assembly
→ S.R. Bommai
→ Rameshwar Prasad
→ Nabam Rebia
→ Subhash Desai
Anti-Defection
→ Kihoto Hollohan
→ Keisham Meghachandra
Legislative Privileges
→ Keshav Singh
→ M.S.M. Sharma
→ Raja Ram Pal
→ Amarinder Singh
Legislative Competence
→ M. Karunanidhi
→ Hoechst Pharmaceuticals
The fastest UPSC revision formula is:
Bommai → 356
Nabam → Governor
Kihoto → Defection
Keisham → Delay
Subhash Desai → Maharashtra Crisis
Keshav Singh → Privilege
Amarinder Singh → State Privilege
Karunanidhi → Repugnancy
Hoechst → Legislative Competence
Kesavananda → Basic Structure
Minerva Mills → Judicial Review + Limited Power
The broader constitutional lesson is:
State Legislature + Federalism + Judicial Review + Responsible Government = Constitutional Balance
