The TMC split has triggered a legal showdown after rebel MPs moved to merge with NCP(I). Senior lawyer Mahesh Jethmalani says once leaders merge with another party, they cannot claim TMC identity or symbol, ruling out any dual role. However, questions remain over the 2/3 rule under the anti-defection law, whether a partial merger is valid, and who ultimately decides party ownership-the Election Commission or internal party structure. Is this a legal escape route or a battle headed for the courts?
