1. Purpose and constitutional framework
Defection means changing political allegiance, especially after obtaining a legislative seat under a particular party label. Frequent defections after the 1967 elections destabilised governments and encouraged bargaining for ministerial office. The expression ‘Aaya Ram, Gaya Ram’ became associated with this phenomenon. A committee chaired by Y. B. Chavan examined the problem before a constitutional remedy eventually emerged in 1985.
The Fifty-second Amendment introduced the Tenth Schedule, applicable to both Houses of Parliament and the Houses of state legislatures. Its objective is to discourage political opportunism, protect the electoral mandate and promote stable government. However, the law addresses legislative membership rather than imposing a general prohibition on switching political parties.
Articles 102(2) and 191(2) provide the constitutional basis for disqualification on the ground of defection. This mechanism differs from disqualifications under Articles 102(1) and 191(1), such as holding an office of profit. Questions under those clauses ordinarily involve the President or Governor acting according to the Election Commission’s opinion; Tenth Schedule disputes go to the House’s presiding officer.
- The law covers MPs and state legislators, not automatically members of local governments.
- It applies to conduct inside the House and, for voluntarily giving up membership, relevant conduct outside it.
- Disqualification removes membership of the House; it is distinct from dismissal from ministerial office.

2. Grounds of disqualification
A member belonging to a political party incurs disqualification by voluntarily giving up membership of that party. Formal resignation is not essential. In Ravi S. Naik v. Union of India, 1994, the Supreme Court held that giving up membership can be inferred from conduct. Nevertheless, disagreement or criticism must be assessed in context rather than automatically treated as defection.
A party member can also be disqualified for voting or abstaining from voting contrary to a direction issued by the political party or a person or authority authorised by it. The member is protected if prior permission was obtained, or if the party or authorised authority condones the conduct within fifteen days of the vote or abstention. This ground is not restricted to confidence motions: it can extend to other legislative votes.
An elected independent member is disqualified upon joining any political party after election. A nominated member who was not already a party member may join a political party within six months from taking the seat without attracting this ground. Joining after that period attracts disqualification. The six-month concession does not apply to elected independents.
For the Schedule, a person elected as a party candidate is deemed to belong to that party. Expulsion does not automatically turn that member into an independent free to join another party. In G. Viswanathan v. Speaker, Tamil Nadu Legislative Assembly, 1996, the Court applied this principle to expelled legislators.
- Remember the difference between voluntarily giving up membership and submitting a formal resignation.
- For a whip violation, distinguish prior permission from condonation within fifteen days.
- The nominated-member clock runs from taking the seat, not simply from the date of nomination.
Typical disqualification proceedings
- 1. Alleged conduct attracts a Tenth Schedule ground
- 2. Petition is submitted under applicable House rules
- 3. Presiding officer gives notice and opportunity to respond
- 4. Evidence, defences and exceptions are examined
- 5. Presiding officer issues a decision
- 6. Constitutional courts may review the decision
3. Merger protection and special exceptions
Paragraph 4 protects members in the context of a qualifying merger of their original political party with another party. The statutory threshold is agreement by not less than two-thirds of the members of the legislature party. ‘Legislature party’ means the party’s members in the particular House, whereas ‘original political party’ refers to the political organisation to which they belong.
The provision protects members who become part of the other or newly formed party through the merger. It also protects members who do not accept the merger and opt to function as a separate group. A two-thirds grouping should not be understood as a general licence to defect: the protection operates through the merger provision, not an independent numerical exemption.
Earlier, paragraph 3 protected a split involving at least one-third of a legislature party. The Ninety-first Amendment deleted this provision. Consequently, a split is no longer a separate defence. The amendment also introduced restrictions on a disqualified defector’s appointment as a minister or to a remunerative political post, through Articles 75(1B), 164(1B) and 361B.
Paragraph 5 provides a narrow exception for specified presiding officers who voluntarily give up party membership because of election to that office. They must remain outside political parties while holding office; they may rejoin their original party on leaving office. The exception is not an unrestricted permission to switch parties.
- The one-third split exemption is obsolete.
- Two-thirds refers to members of the legislature party, not two-thirds of the entire House.
- Specified offices include the Lok Sabha Speaker and Deputy Speaker, Rajya Sabha Deputy Chairman, and corresponding state legislative presiding offices.
| Category | Rule | Key qualification |
|---|---|---|
| Party member | Giving up membership or violating a voting direction | Prior permission or fifteen-day condonation can protect a whip violation |
| Independent member | Joining a political party after election | No six-month concession |
| Nominated member | Joining a party after six months from taking the seat | Initially unaffiliated members may join within six months |
| Merger | Protection under paragraph 4 | Requires agreement of at least two-thirds of the legislature party |
| Split | No separate protection | Former one-third exemption deleted |
4. Decision-making and judicial review
Under paragraph 6, the Chairman or Speaker decides questions of disqualification. If the allegation concerns the presiding officer personally, the House elects another member to decide it. Paragraph 8 permits the presiding officer to frame procedural rules, subject to the Schedule’s requirements, including placement before the House.
In Kihoto Hollohan v. Zachillhu, 1992, the Supreme Court upheld the core anti-defection framework and treated the presiding officer as a tribunal when deciding disputes. Decisions are subject to judicial review for constitutional violations, mala fides, denial of natural justice and perversity. Review ordinarily follows the decision rather than intervening at every procedural stage.
The Court invalidated paragraph 7, which sought to exclude court jurisdiction, because the amendment affecting that jurisdiction had not received the required state ratification under Article 368. The remaining provisions survived. Thus, constitutional language giving finality to the presiding officer’s decision does not eliminate judicial scrutiny.
The Schedule specifies no fixed deadline for deciding petitions. In Keisham Meghachandra Singh v. Speaker, Manipur Legislative Assembly, 2020, the Court stated that, absent exceptional circumstances, three months should be the outer limit. It also suggested considering an independent adjudicatory mechanism. This judicial benchmark is not a deadline expressly written into the Schedule.
- The Election Commission does not decide Tenth Schedule petitions.
- Judicial review and an ordinary statutory appeal are different concepts.
- Procedural delay can affect legislative majorities as seriously as an incorrect decision.
5. Democratic implications and reform
The law discourages individual floor-crossing, reduces inducements to topple governments and reinforces collective party responsibility. Its principal criticism is that extensive use of whips weakens debate and executive accountability. Legislators may become answerable primarily to party leadership rather than exercising judgment on policy or representing constituency preferences.
The Speaker’s party background creates a perceived conflict between impartial adjudication and partisan incentives. Strategic delays, mass defections presented as mergers and resignations used during government formation expose the limits of a purely legal remedy. The law can regulate conduct, but cannot by itself ensure internal party democracy or ethical political competition.
The Dinesh Goswami Committee on Electoral Reforms, 1990, favoured narrowing whip-related disqualification to situations such as confidence, no-confidence and specified financial matters. The Law Commission’s 170th Report also advocated limiting compulsory voting directions to situations affecting government survival. Other proposals favour independent adjudication and enforceable decision timelines. These remain reform debates, not descriptions of the present law.
- For evaluation, balance government stability against legislative deliberation.
- Distinguish existing constitutional provisions, judicial interpretations and recommended reforms.
- Anti-defection reform should accompany greater transparency and democracy within political parties.
Real-world case studies
Karnataka resignations and disqualification, 2019
In Shrimanth Balasaheb Patil v. Speaker, Karnataka Legislative Assembly, the Supreme Court upheld disqualifications but rejected the Speaker’s additional bar on contesting elections for the remaining Assembly term. Resignation does not automatically defeat pending disqualification proceedings, but the Speaker cannot invent an extra electoral prohibition.
Maharashtra political crisis, 2022–2023
In Subhash Desai v. Principal Secretary, Governor of Maharashtra, 2023, the Supreme Court clarified that the political party, not merely its legislature-party faction, authorises the whip. Legislative numerical strength alone does not settle which faction represents the political party for Tenth Schedule purposes.
