He said Katju has written a "wholly misconceived" letter to the Governor and others, including Law Minister Ashwani Kumar and I&B Minister Manish Tewary, members of film fraternity and office bearers of Congress, NCP and Samajwadi parties "have jumped on to his ex-Lordship's bandwagon".
He said Dutt has been convicted under the Arms Act and the Governor's power of pardon under Article 161 of the Constitution does not extend to conviction under this law.
"For their part, Kumar and Tewari, both eminent men of law, would serve the interest of the nation better if they applied their energies to upholding the law, rather than blindly seeking exoneration for a convict who by design or dim-wittedness facilitated the death of so many innocent victims on that fateful day in Mumbai", he said.
"It ill befits a retired Judge of the SC and Chairman of PCI, to display such unseemly haste in seeking complete exoneration for Dutt in the 1993 bomb blast case.
"Hardly has the ink dried on the Supreme Court's judgement upholding the actor's conviction under the Arms Act that the ex-Judge has lamented the decision, extolled Sanjay Dutt's virtues and regretted his suffering of the last twenty years," he said.
