When contacted, the Prime Minister's spokesperson said: "The letter was addressed to the Chief Justice of India, and the PMO had no role to play in it as appointments of judges are decided by the collegium."
Justice Bhattacharya has also given his reasons for opposing the CJI's sister's name for judgeship, including what he has called her poor practice, reflected in her annual income-tax statements.
"In my view as an advocate who at the age of 58 years is just capable of earning a net amount of Rs 88,000 from practice should in no case be recommended for judgeship. We cannot lose sight of the fact that a High Court chaprasi gets more than Rs 13,000 per month as salary which is equivalent to Rs 1,56,000 per annum which is almost double the income of Mrs Shukla Kabir Sinha from her practice as a lawyer," he wrote in his note for the collegium, extracts from which are part of his letter to the CJI.
The letter also says that he had raised the issue of the CJI's sister taking "four years for passing BA examination after clearing senior Cambridge and five years for getting MA degree after graduation, although the usual time taken for clearing these examinations is three years and two years respectively".
"I don't have a personal inimical feeling against Mrs Sinha who is just like my sister... However, as I treat the HC to which I belong for the full time-being as my mother, I earnestly believed that to elevate Mrs Sinha at the age of 59, there is no instance in the past of elevation of a Judge from the Bar at the age of 59 years... would give a wrong signal and people would lose faith in the judiciary and the collegium system...
"For the above reasons, I made my observations which, however, didn't get the approval of the Chief Justice of the Calcutta HC and of Judge Pinaki Chandra Ghose, who was the other member of the collegium and who has superseded me this time," the letter reads. "So far as I can remember, Justice Pinaki Ghose in his recommendation observed that if Shukla Kabir is elevated as a judge, she would be an asset to the judiciary."
Justice Bhattacharya has also written, "When time came for selection of Smt Shukla Kabir Sinha as a Judge of the HC, I was pressured to agree to such a proposal as a member of the collegium, but I thought it would amount to committing rape of the Calcutta HC, which was like my mother and if I didn't raise any objections that would amount to closing my eyes while my mother was being raped.
"As a result, I used rather strong words so that by looking at the nature of words used by me, the person responsible for sending such a recommendation would have a second thought... Unfortunately, I was unsuccessful in resisting the rape of my mother in spite of my earnest endeavour. However, at the time of my death, I will not repent that I ever compromised with wrong for the sake of my career."
While rejecting the claim of the three seniormost CJs, the collegium had said that they were "not suitable to hold the office of Supreme Court judge and their elevation as such would prove to be counter-productive and not conducive to administration of justice," according to a Hindustan Times report which Justice Bhattacharya has quoted in his letter.
