UPSC Civil Services• POLITY• Union Executive• Council of Ministers — 91st Constitutional Amendment and Size of Ministry
The 91st Constitutional Amendment Act, 2003 introduced a 15% ceiling on the Union Council of Ministers based on Lok Sabha strength and a 15% ceiling on State Councils based on Legislative Assembly strength, with a minimum of 12 ministers for States. It also strengthened anti-defection provisions through Articles 75(1B), 164(1B) and 361B. The topic covers the objectives, constitutional provisions, examples, UPSC Prelims facts and traps, significance for coalition politics and political patronage, and a Mains answer framework.

Council of Ministers — 91st Constitutional Amendment and Size of Ministry

Introduction

The Constitution originally did not prescribe a maximum size for the Union Council of Ministers or State Councils of Ministers.

This allowed governments to create very large ministries, often for political accommodation and patronage.

The:

91st Constitutional Amendment Act, 2003

introduced constitutional limits on the size of ministries and strengthened the anti-defection framework.


1. Objectives of the 91st Amendment

The amendment aimed to:

  • Reduce oversized ministries
  • Discourage political patronage
  • Reduce incentives for defections
  • Promote administrative efficiency
  • Strengthen political stability
  • Limit ministerial expansion

2. Union Council of Ministers — 15% Ceiling

Article 75 was amended to provide that:

The total number of ministers, including the Prime Minister, shall not exceed 15% of the total number of members of Lok Sabha.


3. Article 75(1A)

Article 75(1A) provides the:

15% Constitutional Ceiling

for the Union Council of Ministers.


4. What Is Included?

The calculation includes:

  • Prime Minister
  • Cabinet Ministers
  • Ministers of State
  • Deputy Ministers, if appointed

Thus:

Total Council of Ministers ≤ 15% of Lok Sabha Strength


5. Prime Minister Is Included

This is a common UPSC Prelims trap.

The Prime Minister:

Is Included

in calculating the 15% ceiling.


6. What Is the Base?

The ceiling is calculated with reference to:

Total Number of Members of Lok Sabha

It is not based on:

  • Rajya Sabha strength
  • Total Parliament strength
  • Number of Cabinet Ministers
  • Electoral strength of the ruling party

7. Example

Suppose Lok Sabha has:

543 members

15% of 543:

81.45

Since the number of ministers must be a whole number and cannot exceed the constitutional maximum:

Maximum = 81 Ministers

This includes the Prime Minister.


8. Union Maximum

For the present 543-member Lok Sabha:

Maximum Union Council of Ministers = 81


9. Is There a Constitutional Minimum for Union Ministers?

No.

The Constitution does not prescribe a general minimum number of Union ministers.

The Prime Minister determines the composition within constitutional limits.


10. State Council of Ministers

The 91st Amendment also imposed a ceiling on the size of State Councils of Ministers.

The total number of ministers, including the Chief Minister, cannot exceed:

15% of the total number of members of the Legislative Assembly of that State.


11. Minimum Number in States

The Constitution also provides:

The number of ministers, including the Chief Minister, shall not be less than 12.

This minimum applies to:

States

and not the Union.


12. Union vs State

UnionState
Maximum 15% of Lok SabhaMaximum 15% of Legislative Assembly
PM includedCM included
No general minimumMinimum 12
Article 75Article 164

13. Special Rule for Small States

The 15% ceiling could create an extremely small ministry in States with very small Legislative Assemblies.

Therefore, the Constitution provides:

Minimum 12 Ministers

for State Councils.


14. Example — State

Suppose a State Legislative Assembly has:

40 members

15% =

6 ministers

But the Constitution requires a minimum of:

12 ministers

Therefore, the State can have:

12 ministers


15. Important Prelims Trap

The State's minimum of 12:

Does Not Apply to Union Council of Ministers.


16. Article 75(1A) vs Article 164(1A)

Article 75(1A)

Union:

15% of Lok Sabha

Article 164(1A)

State:

15% of Legislative Assembly

with:

Minimum 12


17. Anti-Defection Connection

The 91st Amendment also inserted:

Article 75(1B)

and:

Article 164(1B)

These provisions restrict ministerial appointment of persons disqualified under:

Tenth Schedule


18. Article 75(1B)

A member of either House of Parliament who is disqualified under:

Paragraph 2 of the Tenth Schedule

is disqualified from being appointed as a Minister during the specified period.


19. Article 164(1B)

A member of a State Legislature who is disqualified under the:

Tenth Schedule

is similarly restricted from becoming a Minister during the prescribed period.


20. Why Was This Added?

The amendment attempted to reduce:

Defection for Ministerial Office

A common political incentive for defection is:

Expectation of Ministerial Reward

The amendment sought to reduce this incentive.


21. Six-Month Restriction

A person disqualified under the Tenth Schedule faces restrictions on ministerial appointment for:

The period specified by the Constitution

including the relevant period following the expiry of the term of the House, as provided in Article 75(1B).

The key principle is:

Defection Cannot Be Used as an Immediate Route to Ministerial Office.


22. Article 361B

The 91st Amendment also inserted:

Article 361B

It provides restrictions concerning holding:

Remunerative Political Post

for a person disqualified under the Tenth Schedule.


23. What Is a Remunerative Political Post?

A remunerative political post is a political position carrying:

  • Salary
  • Allowances
  • Other remuneration

as defined under the constitutional framework.


24. Significance of Article 361B

The provision extends the anti-defection consequences beyond ministerial office.

It seeks to prevent:

Political Rewards Following Defection


25. Removal of Article 368(3)

The 91st Amendment also removed the former:

Article 75(1) / State-related provisions

and changed the constitutional structure to strengthen the anti-defection framework.

The most important UPSC-relevant provisions are:

  • Article 75(1A)
  • Article 75(1B)
  • Article 164(1A)
  • Article 164(1B)
  • Article 361B

26. Why Ministry Size Matters

An unrestricted ministry can lead to:

  • Political patronage
  • Financial burden
  • Administrative complexity
  • Weak accountability
  • Coalition bargaining
  • Office distribution for political support

27. Political Patronage

Before the amendment, ministerial office could potentially be used as:

A Political Reward

for supporting the government.

The size ceiling limits the number of such positions.


28. Coalition Governments

The amendment is particularly important for:

Coalition Governments

because coalition partners may demand:

  • Cabinet positions
  • Minister of State positions
  • Other ministerial offices

The 15% ceiling limits the government's ability to expand the ministry indefinitely.


29. Administrative Efficiency

A smaller ministry may promote:

  • Faster decision-making
  • Better coordination
  • Clearer accountability
  • Lower administrative costs

30. Is Smaller Always Better?

Not necessarily.

A very small ministry may create:

  • Excessive workload
  • Portfolio concentration
  • Coordination difficulties
  • Limited political representation

Therefore, the constitutional ceiling establishes:

An Upper Limit

rather than an ideal size.


31. Prime Minister's Role

Within the ceiling, the Prime Minister determines:

  • Who becomes minister
  • Which category they belong to
  • Portfolio allocation
  • Cabinet structure
  • Reshuffling

subject to constitutional requirements.


32. President's Role

The President formally appoints ministers.

However, the appointment of ministers operates on:

The Advice of the Prime Minister


33. Cabinet vs Council Ceiling

The 15% ceiling applies to:

Entire Council of Ministers

It does not mean:

Cabinet alone cannot exceed 15%.

The Cabinet is only a part of the Council.


34. Example

Suppose:

Lok Sabha = 543

Maximum Council = 81

The government could theoretically structure these 81 positions among:

  • Cabinet Ministers
  • Ministers of State
  • Deputy Ministers

according to its organisational requirements.


35. Is 15% Calculated from Actual Vacancies?

No.

The constitutional ceiling is based on:

Total Number of Members of Lok Sabha

not the number of seats currently occupied by ministers or temporary vacancies.


36. Does a Vacant Lok Sabha Seat Reduce the Ceiling?

The constitutional base is:

Total Number of Members of Lok Sabha

Therefore, the calculation is not simply based on the number of currently occupied seats.


37. Important Prelims Point

The Union ministry ceiling is:

15% of Lok Sabha

not:

15% of the Council of States


38. State Ministry Ceiling

For States:

15% of Legislative Assembly Strength

not:

15% of State Legislature including Legislative Council


39. Bicameral State

Even if a State has:

Legislative Council

the ceiling is calculated using:

Legislative Assembly Strength
