As the Central Government filled up the posts for the Chief Information Commissioner (CIC) and the Chief Vigilance Commissioner (CVC) on Monday, the appointment of KV Chowdhary as the latter has irked Supreme Court lawyers Ram Jethmalani and Prashant Bhushan.Since word had got out that Chowdhary was to be made the CVC, both lawyers had written letters to Prime Minister Narendra Modi, questioning Chowdhary’s appointment.While Bhushan has called the CVC’s appointment “shameful and unfortunate”, Jethmalani tweeted out his letter to the PM, calling it his “break-up” with Modi.Both lawyers have also said that they would oppose the appointment of the CVC in the Supreme Court.Jethmalani had first written to the PM in a letter on May 26, in which he said that Jaitley had suggested Chowdhary’s name as the CVC in a meeting which he should not have been a part of in the first place.“I have repeatedly warned you that he has no interest whatsoever in identification and punishment of powerful offenders or in repatriation of the proceeds of their crimes,” he wrote of Jaitley.“KV Chowdhary by no means has a clean record. It is well known that corrupt public servant thrive with the help of corrupt politicians,” Jethmalani wrote.In his letter on June 2, the Rajya Sabha MP has issued another warning, calling Chowdhary’s then purported appointment as the “greatest disaster that will fall on this unfortunate nation.”Calling his letters “installments”, the former BJP member, in his latest letter dated June 8, has said that “The Second, the third and the fourth instalments even more incriminating are ready to be sent to you.”While Jethmalani has desisted from doling out specific allegations, former AAP member Prashant Bhushan, in his letter to the PM on May 20, has pointedly questioned Chowdhary’s role in several cases.In his letter, accessible via his Twitter account, Bhushan alleges that Chowdhary’s name featured in the much controversial list of people who had visited the then CBI director Ranjit Sinha’s residence. Bhushan also accuses Chowdhary of delaying investigations into the Radia tapes, the 2G scam and the black money investigation.“It's shameful and unfortunate that the BJP and the Congress have come together to destroy the CVC (by) appointing a dubious and pliable person as its chief,” Bhushan told IANS.This is the first time that an IAS officer has not headed the Vigilance Commission since its inception in 1964. Chowdhary is a former IRS officer who is working with the SC-appointed SIT team investigating into black money.The post of the CVC had been lying vacant since September 28 last year after Pradeep Kumar’s term had ended.Bhushan and Jethmalani though, have not taken kindly to his appointment and the latter, who had backed the PM in the run up to the elections last year, wrote: “My diminishing respect for you ends today.”Here are the letters by Jethmalani to PM Modi in chronological order: Page 1 of my Letter dated 26.05.2015 to @narendramodi regarding CVC issue.
