Defection as merger: On politics, the wave of defections

What Happened

  • Around 20 Lok Sabha MPs elected on a party ticket formally announced a merger with the Nationalist Citizens Party of India (NCPI), a registered regional party, in an apparent bid to avoid disqualification under the Tenth Schedule.
  • The rebel MPs, representing over two-thirds of their original party's parliamentary strength of 28 MPs in the Lok Sabha, met the Lok Sabha Speaker to formally notify the merger.
  • The original party's leadership approached the Lok Sabha Speaker seeking disqualification of the 20 MPs, arguing the claimed merger does not satisfy constitutional requirements and is an abuse of the Tenth Schedule's merger provision.
  • The dispute centres on whether the rebels' manoeuvre constitutes a valid "merger" under Paragraph 4 of the Tenth Schedule or amounts to political defection punishable with disqualification.
  • The episode has reignited debate about structural weaknesses in India's anti-defection framework and the loopholes that allow legislators to switch sides without formal accountability.

The Tenth Schedule and Anti-Defection Law

The Tenth Schedule was inserted into the Constitution by the Constitution (Fifty-Second Amendment) Act, 1985 to curb the "evil of political defections" that had destabilised governments after the 1967 general elections. It lays down grounds for disqualification of members of Parliament and state legislatures who defect from their original party. Under Paragraph 2, a member becomes liable for disqualification if they voluntarily give up membership of their political party, or vote or abstain contrary to party directions without prior permission.

  • Inserted by the 52nd Constitutional Amendment Act, 1985
  • Applies to both Parliament (via Articles 102(2) and 191(2)) and state legislatures
  • Decision-making authority: the Speaker of the House (for Parliament) or the Chairman (for Rajya Sabha / state legislative councils) — acting in a quasi-judicial capacity
  • Exception for independent members: they are disqualified if they join any political party after election
  • Exception for nominated members: they may join a party within six months of being nominated without disqualification

Connection to this news: The 20 rebel MPs sought to exploit the merger exception under Paragraph 4 to avoid the disqualification that would otherwise follow from their break with the original party.

The Merger Exception (Paragraph 4 of the Tenth Schedule)

Paragraph 4 of the Tenth Schedule provides that disqualification under Paragraph 2 does not apply when a member's original political party merges with another party, provided that at least two-thirds of the members of the legislature party concerned have agreed to the merger. Both the members who merge and those who stay with the original party are protected from disqualification in such an event.

  • Threshold: not less than two-thirds of the legislature party members must consent to the merger
  • The merger must be of the "original political party" — the organisation's formal merger, not merely a legislative bloc decision
  • A mere formation of a separate bloc or group within the legislature does not constitute a merger
  • The 91st Constitutional Amendment Act, 2003 deleted the original Paragraph 3 (which allowed a split with one-third support), tightening the law and leaving merger as the only escape route

Connection to this news: The rebels claim their numbers exceed the two-thirds threshold, making the merger valid. The original party counters that forming a new legislative bloc and joining a different regional party does not constitute a proper merger of the original political party, rendering the claim constitutionally invalid.

Role of the Speaker as Adjudicator

Under the Tenth Schedule, the Speaker (or Chairman) is the sole authority to decide disqualification petitions. This was upheld as constitutional in the landmark case of Kihoto Hollohan v. Zachillhu (1992), where the Supreme Court — by a 3:2 majority — held that vesting adjudicatory power in the Speaker was constitutionally valid. However, the Court also clarified that the Speaker's decisions are not immune from judicial review; they can be challenged before the High Court and Supreme Court under Articles 226 and 136 respectively, but only after the Speaker's order is made, not during the pendency of proceedings.

  • Kihoto Hollohan v. Zachillhu, 1992 Supp (2) SCC 651 — landmark case upholding Tenth Schedule validity
  • Speaker acts in a quasi-judicial (not legislative) capacity when deciding disqualification petitions
  • Judicial review is available, but only post-decision; no interim stay can be granted by courts during Speaker's proceedings
  • A persistent concern in constitutional commentary: the Speaker, being a member of a political party, may lack institutional independence when adjudicating defection cases involving their own party

Connection to this news: The Lok Sabha Speaker will now adjudicate whether the claimed merger is valid under Paragraph 4. This decision will be subject to judicial review if challenged.

Constitutional Amendment Process and the 91st Amendment

The 91st Constitutional Amendment Act, 2003 substantially strengthened the anti-defection framework. It deleted the original Paragraph 3 of the Tenth Schedule (which permitted a "split" if one-third of the legislature party agreed), inserted a provision disqualifying a defector from holding any office under the Council of Ministers (capping the ministerial council at 15% of the lower house strength), and made clear that the only remaining escape from disqualification is a formal merger satisfying the two-thirds threshold.

  • 91st Amendment Act, 2003: deleted the "split" exception (original Paragraph 3)
  • Also added Article 75(1A) — total council of ministers not to exceed 15% of the total strength of the Lok Sabha
  • Impact: made defection far more difficult to legitimise under the law
  • Loophole that persists: the merger route under Paragraph 4 remains available and has been exploited in several states

Connection to this news: The deletion of the split exception in 2003 is precisely why the rebel MPs chose the merger route rather than simply claiming a formal split.
