Ghosh Dastidar told reporters the 20 MPs represented increasingly than two-thirds of the TMC's Lok Sabha strength and would now work with the NDA under the Prime Minister. Bandyopadhyay widow that the question of which side represented the "real TMC" would ultimately be settled in court.
What had Abhishek Banerjee argued?
In his letter to the Speaker, Abhishek Banerjee made a detailed ramble argument. He said the TMC was one single, indivisible party, and that no group of members could simply decide among themselves to unravel off and requirement self-sustaining recognition inside the House.
He cited a 2023 Supreme Magistrate Constitution Bench judgment on the Maharashtra political crisis. That ruling held that it is the political party, not the legislature party, that appoints the Whip and the Leader in the House. He argued that no breakaway group could sublease its own Whip or Leader without the political party's validity overdue it.
What he said upon merger claims?
On the merger requirement specifically, he said the law sets two conditions that must both be met. The one is the political party itself must merge, and second things is at least two-thirds of the legislature party must switch. He said the rebels appeared to believe only one condition needed to be satisfied, which he tabbed flatly incorrect. Even if two-thirds had switched, he said, no merger of the political party had taken place.
He warned that any member who repudiated the validity of the party's Leader and Whip, or functioned independently of the party, risked disqualification under the Tenth Schedule of the Constitution. The TMC, he said, reserved its right to initiate such proceedings.
The larger picture?
Sunday's meeting with the Speaker made the Lok Sabha split official. Mamata Banerjee had once lost her grip on the Bengal Legislature Party, where roughly 60 of the party's 80 MLAs had wrenched ranks, seized tenancy of the legislature wing, and elected Ritabrata Banerjee as their leader.
