"This is not the only issue on which Rajanikanth has not expressed his opinion. But there are several other issues also and it is not right to point only to one issue," he told reporters here.
Kamal, who had met Rajinikanth before launching his party, was replying to a specific question on Rajinikanth maintaining 'silence' on the Cauvery water sharing issue with Karnataka.
Rajinikanth, who has earlier come under flak from various quarters for not actively taking part in protests organised by the film industry in the past over the Cauvery issue, has recently expressed disappointment over the Supreme Court verdict reducing the quantum of water to Tamilnadu from Cauvery river.
He had also urged the state government to file a review petition in the apex court. To a question on the constitution of the Cauvery Management Board, Kamal said the Centre must set up the board immediately.
He replied in the negative when asked whether he had discussed Bhavani river and check dam issue when he met Kerala Chief Minister Pinarayi Vijayan recently.
The actor-politician alleged that the law and order situation in Tamilnadu was deteriorating.
