Supreme Court Petition Seeks CBI Probe into Tamil Nadu’s Alleged Horse-Trading Scandal

There is a petition in the Supreme Court for a CBI to look into some horse-trading in Tamil Nadu, with TVK's Bussy Anand and a few ex-AIADMK MLAs at the centre of it. It's a case that has the potential to put the new government's mettle to the test and change how we see by-elections.

Put before the top court in a hurry, the plea has made a federal issue out of the post-poll mess in Tamil Nadu. The petitioner wants a CBI to go after Bussy Anand and four former AIADMK MLAs, and in doing so, has made a direct link to how the C Joseph Vijay administration was put in place.

This is more than one scandal. You have to ask: will the courts step in when a tenuous mandate is upended by a few resignations? Can by-elections be kept free from what are said to be under-the-table deals?

Why the case matters for Tamil Nadu politics

Should the Supreme Court use Article 142 to put some teeth in the rules on post-election shenanigans, it will be a different game for parties once the results are in. The petitioner is even asking for an interim hold on some by-election hopefuls, which makes for some high drama right now.

The Opposition has been saying there were inducements; the government says no. But by taking it to the apex court, you are no longer talking about the numbers on the floor, but about where the law and the institution draw the line.

What the petition asks the Supreme Court

M Srinivasan, through his lawyer Achintya Tiwari, has filed for a writ of mandamus to get the CBI to open a file. On the other side are N Anand (Bussy Anand) of the TVK and four who used to be with the AIADMK.

Here is what the filing is all about:
– Have the CBI register a case against respondents 07 to 11.
– A probe with a clock on it, and a report to the court to show for it.
– Make some rules to put a stop to horse-trading under Article 142.
– Put a bar on the four ex-MLAs from running in by-elections.

It also tells the CBI to wrap up its work and put in a final report by a date the court deems fit.

Who is named and what triggered the row

The complaint is aimed at N Anand, the TVK general secretary and a minister in the state, over claims he was behind some of the legislative support. All of this is tied to the resignations that changed the balance in the Assembly.

Then you have the four from the AIADMK: K Maragatham Kumaravel (Maduranthakam), S Jayakumar (Perundurai), P Sathyabama (Dharapuram) and Esakki Subaya (Ambasamudram). They left the party and made for the TVK on May 25 and 26. After they were out, the seats were made vacant and put in the Government Gazette.

Background: TVK’s rise and trust vote numbers

When C Joseph Vijay was sworn in as CM on May 10, 2026, he said ‘a new era of real, secular, social justice starts now’. With 108 seats, the TVK had become the single biggest party, breaking up the old DMK-AIADMK order.

Vijay didn’t have the majority in the 234-seat house, but with the Congress, VCK, CPI, CPI (M) and IUML on board, he had 120 MLAs. When the trust vote came on May 13, 25 wayward AIADMK MLAs gave him the nod while the DMK was not in the room.

The Opposition called it what it was: horse-trading. Vijay put that down, saying it was a matter of consent, not force.

What lies ahead in court

The court has been asked to tell the CBI to do its job in a set time. There is also a request for some guidelines under Article 142 to keep people from trading in their positions unless they have a good reason for it.

And to keep those four ex-MLAs off the by-election ballot, whether on their own or with a party, until the ground rules are clear. What comes out of this could well decide who runs and who doesn’t in the coming cycle.

In a way, the judgment here could be the model for other states with thin majorities. For the people in Tamil Nadu, it is a first look at whether the new regime and the system are serious about a cleaner kind of politics.
