Core Points

• The anti-defection law was introduced through the 52nd Constitutional Amendment Act, 1985, which inserted the Tenth Schedule.
• It sought to prevent political instability caused by legislators changing parties or defying their parties to obtain office or other advantage.
• The 91st Constitutional Amendment Act, 2003 removed the exemption previously available to a split involving at least one-third of a legislature party.
• Disqualification does not apply where at least two-thirds of the members of a legislature party agree to a merger with another political party.
• Retaining the two-thirds exemption has shifted political incentives from individual defections towards larger, organised realignments.
• Decisions on disqualification are taken by the Speaker or Chairman. Delayed decisions can allow a legislator to retain office, influence confidence votes or complete much of the House’s tenure.
• The Supreme Court has held that, absent exceptional circumstances, disqualification petitions should ordinarily be decided within three months. Keisham Meghachandra Singh v. Speaker, Manipur Legislative Assembly
• Vesting adjudicatory authority in a presiding officer associated with party politics creates recurring concerns about impartiality.
• Defection changes not only party arithmetic but also the representative basis on which the legislator obtained the electoral mandate.
• An automatic vacancy followed by a fresh election could return the decision to voters, but it might encourage repeated by-elections or strategic resignations unless carefully designed.
• Restricting disqualification to votes affecting government survival, financial legislation and formally declared manifesto commitments could protect stability without eliminating ordinary legislative dissent.
• Reform must address adjudicatory independence, enforceable timelines, internal party democracy and the scope of binding party whips.

Prelims Relevance

• The Tenth Schedule contains the constitutional provisions relating to defection.
• Articles 102(2) and 191(2) connect Tenth Schedule disqualification with Parliament and State Legislatures.
• Voluntarily giving up party membership can be inferred from conduct and does not require a formal resignation.
• A legislator may also be disqualified for voting or abstaining against a party direction without prior permission, unless the act is condoned within 15 days.
• An independent member is disqualified for joining a political party after election.
• A nominated member may join a political party within six months of taking the seat without attracting disqualification.

Mains Relevance

• GS II: Anti-defection law, presiding officers, legislative accountability and electoral reform.
• GS II: Role of political parties, representative democracy and legislative deliberation.
• GS IV: Public office, political integrity and accountability to voters.

Supporting Fact Box

• Speaker’s decision and judicial review: In Kihoto Hollohan v. Zachillhu (1992), the Supreme Court upheld the Tenth Schedule while permitting judicial review of the presiding officer’s final decision.
• Merger requirement: Protection requires at least two-thirds of the legislature party; a split by one-third members no longer receives protection.
• Presiding officer exemption: A Speaker, Deputy Speaker, Deputy Chairman or Chairman may give up party membership after election to that office without disqualification, subject to the Schedule’s conditions.
• Ministerial limit: The 91st Amendment limits the Union and State Councils of Ministers to 15% of the strength of the popular House, subject to a minimum of 12 ministers in a state.
• Disqualified defectors: A member disqualified under the Tenth Schedule cannot be appointed a minister until re-election or expiry of the original legislative term.
