The Madras High Court dismissed a public interest litigation seeking a Central Bureau of Investigation (CBI) probe into the resignation of four AIADMK legislators and their subsequent entry into the Tamilaga Vettri Kazhagam (TVK), holding that the petition was founded on suspicion rather than concrete evidence.
Background of the Case
The case, filed by advocate and AIADMK member B. Ramkumar Adityan, sought directions for the CBI to investigate alleged irregularities and corruption linked to the resignation of four elected MLAs from the Tamil Nadu Legislative Assembly and their immediate switch to TVK. The petitioner also requested criminal action under the Prevention of Corruption Act.
According to the plea, the MLAs had contested the 2026 Assembly election on AIADMK tickets but later voted in support of the TVK-led government during a confidence motion. After disqualification proceedings were initiated, they resigned from the Assembly and joined TVK. The petitioner alleged that such a rapid political shift raised questions about possible inducements and political bargaining.
A Division Bench comprising Chief Justice Sushrut Arvind Dharmadhikari and Justice G. Arul Murugan closely examined the allegations and found that the petition contained no supporting material capable of justifying a court-ordered investigation.
The Bench observed that the entire case rested on assumptions and generalized accusations.
“The entire edifice of the writ petition rests upon conjectures, suspicion and a total absence of foundational material facts,” the court noted while rejecting the claims of corruption and financial inducement.
The judges emphasized that constitutional courts cannot order investigations by specialized agencies like the CBI merely because a litigant believes wrongdoing may have occurred. They reiterated that public interest petitions involving elected representatives must be supported by precise facts and credible material rather than speculation.
Referring to Supreme Court precedents, the Bench said a CBI inquiry can be directed only in rare and exceptional situations where a prima facie case is established through evidence and where an independent investigation is necessary to maintain public confidence in the justice system.
During the hearing, the court specifically asked whether any documents or material had been produced to support the allegations. The petitioner relied on judicial precedents but could not place any factual evidence before the court.
The Bench remarked that court judgments may explain legal principles, but they cannot replace the basic facts that a petitioner must establish.
The judges further stated that even if the resignations resulted in financial costs associated with conducting by-elections, such political decisions do not automatically amount to criminal misconduct under anti-corruption laws without proof of an unlawful arrangement or benefit.
Holding that the petition was based on assumptions and lacked specific factual details, the Madras High Court dismissed the plea seeking a CBI investigation.
The court concluded that the case was legally unsustainable and declined to grant any relief.
