"Since these are court matters, I don't want to give much opinion," he told reporters here.
The Supreme Court had referred the matter on remission of life imprisonment of seven convicts in the case to a Constitution Bench and said its interim order staying Tamil Nadu government's decision to free them will continue.
A bench headed by Chief Justice P Sathasivam said that the petition filed by the Centre, challenging the Tamil Nadu government's decision to remit the sentences, will be decided by the Constitution Bench.
Karunanidhi had on Saturday said that Justice Sathasivam's indication that the verdict on the petition relating to release of all seven life convicts in Rajiv Gandhi assassination case would be given in a week had led to fears of a political fallout in Tamil Nadu ahead of the April 24 Lok Sabha polls.
"With polling scheduled on April 24, Justice Sathasivam saying that an important verdict will be pronounced before his retirement date of April 25 has led to fears among many if it will lead to a political fallout and created a big debate among advocates," he had said.
