Seven out of ten AAP Rajya Sabha MPs defected to BJP, invoking the two-thirds merger clause under the Tenth Schedule to avoid disqualification, marking a significant political realignment and testing the robustness of anti-defection laws.

Key points

Anti-Defection Law (Tenth Schedule): The defection of seven AAP Rajya Sabha MPs to BJP is protected under the Tenth Schedule's two-thirds merger clause, shielding them from disqualification.

Rajya Sabha Composition: BJP's strength in Rajya Sabha will rise to 113, and NDA's to 148, inching closer to the two-thirds majority mark of 163, which is crucial for passing constitutional amendments.

Legal Threshold: The 91st Constitutional Amendment Act (2003) mandates that at least two-thirds of a party's elected members must consent to a merger for it to be legally recognized.

Role of Rajya Sabha Chairman: The Chairman must determine if the merger complies with the anti-defection law, a decision that could set a precedent for future defections.

[GS2-Governance] This incident highlights the need for stronger internal party democracy and stricter enforcement of anti-defection laws to prevent political opportunism.

Historical Precedent: Similar mergers, like the 2019 TDP Parliamentary Party's merger with BJP, have been upheld under the same legal provisions.

Election Commission's Role: In case of a split, the EC must decide which faction retains the party's symbol, based on legislative majority claims.

Way Forward: Amend the Tenth Schedule to explicitly define 'merger' and 'split' to prevent misuse, establish an independent tribunal to adjudicate defection cases, and mandate transparency in political party funding to reduce defection incentives.

Key terms

Tenth Schedule of the Constitution

The Tenth Schedule, also known as the Anti-Defection Law, was added by the 52nd Amendment Act (1985) to prevent political defections. It disqualifies MPs/MLAs who voluntarily give up party membership or vote against party directives, except when two-thirds of a party's members merge with another party. This is crucial for UPSC as it tests the balance between party discipline and legislative freedom.

91st Constitutional Amendment Act (2003)

This amendment strengthened the Anti-Defection Law by reducing the threshold for disqualification from one-third to two-thirds for splits and banning defectors from holding public office. It is significant for UPSC as it reflects efforts to curb political instability and promote ethical governance.

Rajya Sabha

The Rajya Sabha, or Council of States, is the upper house of India's Parliament, representing states and union territories. Its members are elected by state legislatures, ensuring federal representation. For UPSC, understanding its role in legislation, constitutional amendments, and checks on Lok Sabha is vital.

Election Commission of India

An autonomous constitutional body (Article 324) responsible for administering elections, including recognizing political parties and allocating symbols. Its role in adjudicating party splits and ensuring fair elections is critical for UPSC's polity and governance topics.
