The government on Wednesday transferred Santokh Singh, legal adviser to the Department of Telecom (DoT) and considered a close aide of former telecom minister A Raja, to the law ministry.
Sources in the know confirmed the development.
Singh was associated with the controversial affidavit filed by the DoT in the Supreme Court, which said that all decisions taken on new unified access service (UAS) licences and allocation of 2G spectrum to new operators had the concurrence of the Prime Minister.
The affidavit resulted in Prime Minister's name being dragged into the 2G spectrum case in the Supreme Court.
The affidavit was filed by the DoT in response to a PIL filed by Janata Party leader Subramanian Swamy seeking sanction for launching prosecution proceedings against Raja and other allegedly involved in the alleged scam over allocation of 2G spectrum.
The decision to transfer Singh came just few months ahead of his superannuation. He was with the DoT for over four years and advised the department on several important issues relating to 2G spectrum allocation and 3G spectrum auction.
Singh is the second senior official who has been transferred after R K Chandolia, former economic adviser.
