⚖️ Anti-Defection Law

Context

Six out of nine Lok Sabha MPs from a Shiv Sena faction are reportedly planning to defect to the rival faction led by Maharashtra's Deputy Chief Minister, bringing renewed attention to India's Anti-Defection Law.

What is the Anti-Defection Law?

  • The Anti-Defection Law is contained in the Tenth Schedule of the Constitution of India.
  • It penalizes elected legislators who change political allegiance after being elected.
  • It applies to both Members of Parliament (MPs) and Members of Legislative Assemblies (MLAs).
Aim: To prevent political defections, ensure government stability, and protect the integrity of electoral mandates.

Grounds for Defection and Disqualification

Key Features and Exemptions

  • Two-Thirds Merger Rule (Para 4): No disqualification if at least two-thirds of legislators support a merger with another political party.
  • Abolition of Split Provision: The 91st Constitutional Amendment Act, 2003 removed protection earlier available to one-third splits.
  • Presiding Officer Exemption: Speaker/Deputy Speaker may resign from their political party upon election to the office to maintain neutrality.

Important Judicial Interpretations

  • Defection can be inferred from conduct.
  • Formal resignation from the party is not necessary.

Girish Chodankar v. Speaker, Goa Assembly (2022)

  • A two-thirds breakaway group joining another party may qualify as a valid merger.

Subhash Desai v. Principal Secretary, Maharashtra (2023)

  • After deletion of Para 3, a split is no longer a valid defence.
  • The real political party is determined by its constitution and organizational leadership, not merely by legislative majority.

Significance of the Law

  • Promotes political stability.
  • Prevents opportunistic party switching.
  • Protects the electoral mandate of voters.
  • Strengthens party discipline within legislatures.
  • Reduces the possibility of government collapse through defections.
