Meaning

The 91st Constitutional Amendment Act, 2003 was introduced to strengthen the Anti-Defection Law and reduce the size of the Council of Ministers.

It amended provisions related to:

• Council of Ministers
• Anti-defection law
• Ministerial appointments
• Political defections
• Tenth Schedule

The amendment mainly aimed to control political instability, jumbo ministries, and misuse of ministerial posts to reward defectors.

Background

After the 52nd Constitutional Amendment Act, 1985, India had an Anti-Defection Law under the Tenth Schedule.

However, the law had a major weakness.

It allowed a split in a political party if at least one-third members of the legislature party broke away.

This one-third split provision was frequently misused.

Instead of preventing defections, it encouraged group defections. Politicians could avoid disqualification by engineering a split with the required number of members.

This created problems such as:

• Horse-trading
• Political instability
• Artificial party splits
• Large-scale defections
• Rewarding defectors with ministerial posts
• Very large Council of Ministers
• Weakening of constitutional morality

The 91st Amendment was introduced to correct these problems.

Main Objectives

The amendment aimed to:

• Strengthen anti-defection provisions
• Remove the one-third split loophole
• Discourage mass defections
• Limit the size of ministries
• Reduce political bargaining for ministerial posts
• Improve political stability
• Strengthen public trust in representative institutions
• Prevent defectors from immediately becoming ministers

Limit on Council of Ministers

One of the most important changes was the limit on the size of the Council of Ministers.

The amendment inserted Article 75(1A) for the Union government.

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

This was done to prevent the creation of unnecessarily large ministries.

Earlier, ministerial posts were often used as political rewards to satisfy factions, coalition partners or defectors.

Limit in States

The amendment also inserted Article 164(1A) for the states.

It says that the total number of ministers, including the Chief Minister, shall not exceed 15% of the total number of members of the State Legislative Assembly.

However, there is also a minimum requirement.

The number of ministers in a state, including the Chief Minister, cannot be less than 12.

This provision was added because some smaller states have small assemblies, and a strict 15% formula could make the ministry too small for practical governance.

Disqualification from Becoming Minister

The amendment inserted Article 75(1B) at the Union level.

It says that a member of either House of Parliament who is disqualified under the Tenth Schedule shall also be disqualified from being appointed as a minister.

This disqualification continues until:

• The term of that member’s House expires, or
• The member is re-elected to Parliament

Similarly, Article 164(1B) was inserted for states.

It says that a member of a State Legislature disqualified under the Tenth Schedule cannot be appointed as a minister until:

• The term of the House expires, or
• The member is re-elected to the State Legislature

This provision was meant to stop defectors from being rewarded immediately with ministerial posts.

Disqualification from Remunerative Political Posts

The amendment inserted Article 361B.

This provision says that a member disqualified under the Tenth Schedule is also disqualified from holding any remunerative political post.

This disqualification continues until:

• The term of the House expires, or
• The member is re-elected

A remunerative political post means a political office where the person receives salary or financial benefit from the government.

This was added to stop defectors from being rewarded with posts even if they were not made ministers.

Removal of Split Provision

The most important anti-defection reform was the removal of the one-third split exception from the Tenth Schedule.

Before the 91st Amendment:

• If one-third members of a legislature party split, they could avoid disqualification.

After the 91st Amendment:

• The one-third split exception was removed.
• Only merger with another political party is protected.
• For a valid merger, at least two-thirds members of the legislature party must agree.

This made the anti-defection law stricter.

Merger Provision

The amendment retained the merger exception.

A member is not disqualified if their original political party merges with another party and the merger is supported by at least two-thirds members of the legislature party.

This means:

• Individual defection is punishable
• One-third split is no longer protected
• Two-thirds merger is still allowed

However, even the two-thirds merger rule has been criticised because it can still allow large-scale political shifts.

Key Changes Introduced

The amendment introduced the following major changes:

• Added Article 75(1A): Council of Ministers at Union level limited to 15% of Lok Sabha strength
• Added Article 75(1B): Defector disqualified from becoming Union Minister
• Added Article 164(1A): Council of Ministers in states limited to 15% of Assembly strength, with minimum 12 ministers
• Added Article 164(1B): Defector disqualified from becoming State Minister
• Added Article 361B: Defector barred from holding remunerative political post
• Amended the Tenth Schedule
• Removed the one-third split exception
• Retained the two-thirds merger exception

Significance

The 91st Amendment was important because it tried to clean up two major problems in Indian politics.

First, it made the Anti-Defection Law stricter by removing the split loophole.

Second, it limited the size of ministries, reducing the possibility of using ministerial posts as political rewards.

Its significance can be seen in the following ways:

• Reduced jumbo ministries
• Controlled political bargaining
• Strengthened anti-defection law
• Reduced open horse-trading
• Promoted stability in governments
• Protected voters’ mandate
• Discouraged reward-based defections
• Improved constitutional discipline in formation of ministries

Impact on Political System

The amendment brought more discipline to government formation.

Earlier, governments could create large ministries to satisfy many MLAs or MPs. This increased public expenditure and weakened administrative efficiency.

After the amendment, ministries had to remain within a fixed constitutional limit.

The removal of the split provision also made it harder for small groups of legislators to defect without consequences.

However, political actors later found new methods to bypass the law, such as:

• Mass resignations
• Delayed Speaker decisions
• Two-thirds merger claims
• Post-election alliances
• Strategic abstentions
• Defections followed by re-election

Limitations

The amendment strengthened the law, but it did not fully solve the problem of defection.

Major limitations include:

• Two-thirds merger provision can still be misused
• Speakers may delay decisions on disqualification petitions
• Defectors may resign and contest again
• Party leadership became stronger than individual legislators
• Ordinary legislative dissent remains restricted
• Anti-defection cases can become politically selective
• Judicial review often comes after political advantage is already achieved

The amendment reduced one loophole but did not remove the political incentives behind defection.

Criticism

The amendment has been criticised on several grounds.

It made party discipline stronger, but it also reduced the independence of elected representatives.

Because of strict anti-defection provisions, MPs and MLAs often hesitate to vote according to their conscience, local interests or independent judgment.

Main criticisms include:

• It strengthens party high command culture
• It weakens internal party democracy
• It limits free debate in legislatures
• It gives excessive importance to party whips
• It does not fully prevent mass defections
• It does not solve the problem of Speaker bias
• It fails to prevent resignation-based political manipulation

Important Judicial Context

Kihoto Hollohan Case

In Kihoto Hollohan v. Zachillhu, 1992, the Supreme Court upheld the validity of the Anti-Defection Law.

The Court held that the Speaker’s decision under the Tenth Schedule is subject to judicial review.

This case remains important because the 91st Amendment strengthened the same anti-defection framework.

Keisham Meghachandra Singh Case

In Keisham Meghachandra Singh v. Speaker, Manipur Legislative Assembly, 2020, the Supreme Court observed that Speakers should ideally decide defection petitions within three months, unless exceptional circumstances exist.

This case highlighted that delay in deciding defection cases can defeat the purpose of the Anti-Defection Law.

Way Forward

Further reforms may include:

• Fixed time limit for deciding defection cases
• Independent tribunal instead of Speaker for disqualification
• Limiting whip only to confidence motions, no-confidence motions and money bills
• Stronger internal democracy within political parties
• Faster judicial review in defection matters
• Clearer rules on resignation before disqualification
• Review of the two-thirds merger provision
• Greater transparency in coalition politics

Conclusion

The 91st Constitutional Amendment Act, 2003 was an important reform aimed at strengthening the Anti-Defection Law and reducing the misuse of ministerial posts.

It removed the one-third split loophole, retained the two-thirds merger provision, limited the size of the Council of Ministers and barred defectors from becoming ministers or holding remunerative political posts.

However, while the amendment made defections more difficult, it did not eliminate the political culture of opportunistic party switching. Its working shows that legal reform must be supported by internal party democracy, impartial decision-making and stronger constitutional morality.
