Subramaniam is believed to have been miffed with the government move to hire a private lawyer to represent the Telecom Ministry on the 2G spectrum scam in the Supreme Court. He also considered the move belittling to his position.
The Solicitor General had come under fire earlier by the Supreme Court after the apex body sought an affidavit from the government over Prime Minister Manmohan Singh's inaction in the controversial issues that cropped up during A Raja's tenure as Telecom Minister. It was during this time that the 2G spectrum scam blew up causing huge loss to the country's exchequer.
Though Subramaniam ignored the apparent snub, the government went a step further and asked Attorney General G E Vahanvati to represent the Prime Minister in the Supreme Court instead of the Solicitor General. Meanwhile, Subramaniam continued to represent the Telecom Department.
