In a setback to former Tamil Nadu Minister V. Senthil Balaji, the Supreme Court on Monday (May 11, 2026) refused to interfere with a Madras High Court order directing a CBI probe into an alleged ₹397-crore scam in the procurement of transformers during his tenure as the State’s Electricity Minister between 2021 and 2023.

A bench of justices Vikram Nath and Sandeep Mehta refused to entertain the plea challenging the Madras High Court’s (HC) direction for a CBI probe into the alleged irregularities.

Senior advocate Siddharth Dave, appearing for an official of the Tamil Nadu Generation and Distribution Corporation (TANGEDCO), said there was no specific prayer before the HC seeking a CBI investigation and contended that the proceedings were politically motivated.

“There was no prayer for a CBI enquiry before the HC. It’s a politically motivated case,” Mr. Dave submitted.

Justice Nath said the court was empowered to direct such a probe if the circumstances warranted.

“We don’t need a prayer. It depends upon how the court feels,” the Bench observed.

Declining to entertain the special leave petition against the HC order, the apex court ordered that it was not inclined to entertain the appeal and said investigation in the matter should proceed independently without being influenced by any observations made by the HC.

On April 29, the HC ordered a CBI inquiry into the alleged irregularities surrounding the procurement of 45,000 distribution transformers by the Tamil Nadu Government.

Following the HC order, Mr. Balaji had maintained that all procedures were duly followed in the tender process and that no irregularities were committed in the procurement of transformers.

The DMK leader also said the procedures of procurement had been in place since 1987 and that the “same procedures were followed till now”.

The HC order came on allegations that the State exchequer suffered a loss of ₹397 crore between 2021 and 2023.

The court passed the order on a petition filed by NGO Arappor Iyakkam seeking an inquiry by a Special Investigation Team, while AIADMK legal wing functionaries E Saravanan and Rajkumar sought a CBI probe into the alleged irregularities.

The petitioners alleged that irregularities amounting to ₹397 crore took place in the procurement of 45,000 transformers during Mr. Balaji’s tenure as Electricity Minister in the then DMK Government.

The HC directed that all related complaints be transferred to the CBI for a detailed investigation.

Ordering the CBI to conduct a fresh investigation into this matter, the HC directed the Directorate of Vigilance and Anti-Corruption (DVAC) to hand over all documents related to the case to the central agency within two weeks.

It had further directed the CBI, upon receiving the documents, to conduct and conclude the investigation expeditiously and to take appropriate action in accordance with the law.

The HC also ordered TANGEDCO, the DVAC, and the Tamil Nadu Government to extend their full cooperation to the CBI during the investigation.
