In a statement, AMMK's TTV Dhinakaran said the decision to expel Kamaraj was taken because he had acted independently against the party's official stand by expressing support for TVK in the Assembly.
Dhinakaran and the complainants — M A Muniasamy, Ramanathapuram district secretary of the AIADMK, and R M Babu Murugavel, the spokesperson for the party — were present in the court.
