Added by the 52nd Amendment (1985), this schedule provides for the disqualification of MPs and MLAs on grounds of defection, aimed at ensuring political stability and party discipline.
UPSC context
GS Paper II: Essential for topics on Parliament, State Legislatures, and the integrity of democratic institutions.
Dravida Munnetra Kazhagam (DMK)
A major regional party in Tamil Nadu founded by C.N. Annadurai in 1949. It advocates for social justice, state autonomy, and Dravidian identity, currently leading the state government.
UPSC context
GS Paper II: Significant for studying regional parties, federalism, and the evolution of Dravidian politics.
All India Anna Dravida Munnetra Kazhagam (AIADMK)
A regional party in Tamil Nadu formed by M.G. Ramachandran in 1972 after splitting from the DMK. It has historically focused on welfare schemes and a strong central outlook.
UPSC context
GS Paper II: Relevant for understanding factionalism in regional parties and their impact on state governance.
91st Constitutional Amendment Act, 2003
This 2003 amendment strengthened the Tenth Schedule by removing the 'split' exception (1/3rd members) and limiting the size of the Council of Ministers to 15% of the House strength.
UPSC context
GS Paper II: Tests knowledge of constitutional amendments aimed at curbing executive overreach and political instability.
Presiding Officer (Speaker/Chairman)
The final authority for deciding disqualification under the Tenth Schedule. Their decisions are subject to judicial review for mala fide intent as per the Kihoto Hollohan case.
UPSC context
GS Paper II: Critical for topics on the impartiality of constitutional offices and the separation of powers.
Expelled Member Status
Under the Tenth Schedule, an expelled member is still treated as belonging to their original party. Joining another party can be deemed 'voluntarily giving up membership,' leading to disqualification.
UPSC context
GS Paper II: Tests understanding of legal nuances and Supreme Court interpretations like the G. Viswanathan case.
Prelims Trap
An expelled legislator is treated as an independent and is immune from Tenth Schedule disqualification if they join a new party.
Under the SC's G. Viswanathan ruling (1996), an expelled member remains legally tied to their original party under the Tenth Schedule. Joining another party triggers disqualification.
Static Concepts Connected
How does the Tenth Schedule treat expelled legislators?
- G. Viswanathan ruling: The Supreme Court held that an expelled member continues to legally belong to their original political party for the purposes of the Tenth Schedule.
- Disqualification trigger: If an expelled member subsequently joins another political party, they attract disqualification for 'voluntarily giving up membership' of their original party.
How did the 91st Constitutional Amendment Act (2003) change the Anti-Defection Law?
- Split provision removed: It completely omitted the provision that previously protected legislators from disqualification if a 'split' by at least one-third of the legislature party occurred.
- Merger threshold: Currently, exemption from disqualification is only permitted if a party 'merges' with another, provided at least two-thirds of its legislative party members agree.
- Council size capped: The amendment simultaneously capped the total size of the Council of Ministers (including the PM/CM) at 15% of the total strength of the Lower House.
Cross-Topic Patterns
Speaker's Defection powers vs ECI's Symbol allocation
While the Speaker exclusively decides Tenth Schedule defection matters, the Election Commission independently adjudicates which faction retains the official party symbol under the Election Symbols (Reservation and Allotment) Order, 1968.
Judicial review of the Speaker's inaction
Stemming from the Kihoto Hollohan (1992) ruling, the Supreme Court has increasingly intervened to compel Speakers to decide defection petitions within a reasonable timeframe (typically 3 months), curbing partisan delays.
Prelims 2026 will likely test the contrasting Tenth Schedule rules for an 'expelled member' versus a 'nominated member' joining a party.
