JD(U) Secretary General K C Tyagi also said that there should not be any political interference in the legal processes.
"It would be good if Katju remains as the chief of PCI instead of becoming the spokesperson of any party. He has been giving his opinion on everything right from Bihar to Sanjay Dutt," he said.
Tyagi also wondered whether Katju will do the same for other convicts in the 1993 Mumbai blasts case.
Tyagi said that Dutt's acting skills should be admired but his party will not in any way back his wrong deeds.

"There should not be any interference of political people in it, whether it is Katju or Amar Singh. His (Dutt's) acting skills should be admired. He did a good job in Munna Bhai (films) but we are not going to back the wrong things he did," he said.
"Dangerous weapons were found in his house. Instead of saying that he is the son of someone, it will be more appropriate to say that his conduct has proven to be disgraceful," Tyagi said.
"Sanjay Dutt's parents were glorious people, who used to spread the message of patriotism across the country. But Sanjay Dutt has done just the opposite," he added.
