Madras HC Dismisses PIL Seeking CBI Probe into MLA Resignations and Switch to TVK as Conjecture-Based Fishing Expedition

The Madras High Court dismissed a PIL by an AIADMK advocate demanding a CBI inquiry into four MLAs who resigned and joined TVK, finding no tangible material beyond suspicion.

A Division Bench of the Madras High Court, led by Chief Justice Sushrut Arvind Dharmadhikari and Justice G. Arul Murugan, dismissed a public interest litigation on 16 June 2026 that sought a writ of mandamus directing the Central Bureau of Investigation to probe alleged corruption behind the resignations of four AIADMK MLAs from the 17th Tamil Nadu Legislative Assembly and their immediate entry into the Tamilaga Vettri Kazhagam. The bench found the petition built entirely on conjecture and suspicion, with no foundational material to support the allegation of illicit gratification. The court held that directing a CBI investigation on such a basis would amount to ordering a fishing expedition, which Article 226 does not permit.

The Dispute Before the High Court

The petitioner, B. Ramkumar Adityan, a practising advocate and member of AIADMK, filed W.P.No.22340 of 2026 under Article 226 of the Constitution of India. He named seventeen respondents, including the Secretaries of the Ministry of Home Affairs and the Ministry of Law and Justice, the Chief Election Commissioner, Tamil Nadu government officials, the CBI Director and its Regional Director in Chennai, the Director General of Police Tamil Nadu, and the general secretaries of both AIADMK and TVK.

The factual backdrop, as set out in the petitioner's affidavit, was this: after the general elections to the 17th Tamil Nadu Legislative Assembly held on 23 April 2026, TVK emerged as the single largest party with 108 seats but fell short of the majority threshold of 118 in a House of 234. TVK forged a coalition and a vote of confidence was executed on 13 May 2026. Respondents 12 to 15 — who had contested and won as AIADMK candidates — allegedly voted in favour of the TVK government during the floor test, contrary to the whip issued by AIADMK. Disqualification petitions under the Tenth Schedule were filed before the Speaker. Before those petitions could be decided, respondents 12 to 15 tendered their resignations from the Assembly on 25 and 26 May 2026. The Speaker accepted the resignations. The four then joined TVK.

The petitioner's core argument was that legislators who had spent up to the statutory ceiling of Rs. 40,00,000 on their election campaigns could not have surrendered their seats within days of taking the oath unless induced by illicit gratification or promises of executive or political office. He characterised the conduct as “party-hopping” and “political horse-trading” amounting to a “murder of democracy,” and contended that the resulting bye-elections would impose a burden of approximately Rs. 100 crores on the public exchequer. He had made complaints to the CBI on 27 May 2026 and 30 May 2026. Receiving no response, he approached the High Court.

The Legal Issue

The central question was whether a constitutional court can direct the CBI to investigate alleged corruption in the absence of any concrete evidentiary material, relying solely on the inference that rapid party-switching must have been induced by financial inducement.

The petitioner sought to invoke the Prevention of Corruption Act, 1988 as amended in 2018, and prayed for criminal proceedings to be initiated against the respondents. The prayer was framed as a mandamus to the CBI to investigate “irregularities and corruption” in the matter of the resignations and the subsequent party switch.

How the Bench Reasoned

The bench, in an order authored by the Chief Justice, examined the pleadings, affidavits, and the materials in the typed set of papers. Its assessment was direct: the entire edifice of the writ petition rested on conjectures, suspicion, and a total absence of foundational material facts. The petitioner had made highly generalised, sweeping, and vague allegations of corruption and financial inducement without producing an iota of tangible material.

When the court specifically asked whether any documents supported the assertions in the writ petition, counsel for the petitioner referred only to decisions of the Supreme Court. The bench rejected that approach plainly: judgments and legal precedents are authorities for the propositions of law they decide and do not serve as a substitute for the foundational facts that a petitioner is bound to establish within the four corners of his pleadings.

The bench restated the governing constitutional principle that a CBI investigation cannot be ordered as a matter of course solely on the subjective belief of a litigant. Pleadings in a PIL targeting public dignitaries and elected representatives must carry a high degree of precision and must be backed by relevant material, not speculative hypothesis.

The court relied on the Supreme Court's decision in Save Mon Region Federation and Another v. State of Uttar Pradesh (2026 INSC 320), which consolidated the jurisprudence on CBI directions. That decision, drawing on the earlier Constitutional Bench ruling in State of W.B. v. Committee for Protection of Democratic Rights (2010) 3 SCC 571, held that while a constitutional court has the authority to direct a CBI inquiry, the power must be exercised with great restraint. The extraordinary jurisdiction is to be invoked sparingly and only in exceptional situations where a prima facie case of a clear cognizable offence is established by evidentiary facts — not merely because allegations have been levelled.

The Save Mon Region Federation decision identified three conditions a court ordinarily examines before entrusting investigation to the CBI: whether the material discloses a prima facie case raising serious questions of legality; whether circumstances suggest that investigation by ordinary State machinery may not inspire confidence where high public functionaries are implicated; and whether an independent inquiry is necessary to preserve public confidence in the rule of law. None of those conditions were met here.

The bench also addressed the petitioner's broader political grievance. It acknowledged that a sudden realignment of political loyalty by respondents 12 to 15 may cause financial strain due to the necessity of conducting bye-elections. But it held that such political choices do not ipso facto translate into criminal misconduct under the Prevention of Corruption Act in the complete absence of proof of an unlawful quid pro quo. The inference that spending up to the election expenditure ceiling and then resigning must mean corruption is not a substitute for evidence of an actual corrupt transaction.

Outcome

The Division Bench held the writ petition to be entirely misconceived, devoid of specific factual details, and legally unsustainable. W.P.No.22340 of 2026 was dismissed without costs on 16 June 2026.
