The Kasab verdict has come as the culmination of one of India's most sensational terror attack cases in the history of the country, and playing a major part in the development was senior counsel Gopal Subramanium.
Subramanium's legal acumen in presenting the prosecution's side in terror cases had earlier made the Supreme Court pass the death sentence on the accused in the Red Fort and Parliament attack cases.
A distinguished lawyer at the apex court, he charged a token fee of Rs. 1 from the Maharashtra government for appearing on behalf of the state against Kasab.
At the start of the proceedings, Subramanium had stated that though he was appearing for the prosecution, he would like to wish Kasab the very best.
His "warm and stimulating" arguments made the court observe: "Mr Subramanium, erudite and sensitive, was full of restraint; always downplaying the prosecution's case by a notch or two and never making a statement of fact unless absolutely certain of its correctness."
Subramanium, on the other hand, modestly admitted that he had only conducted the case in a professional manner.
Appointed as the solicitor general of India in 2009, he has represented the government in many important cases. He resigned from the post this year.
Subramanium is currently assisting the SC in the Sohrabuddin Sheikh fake encounter case involving former Gujarat home minister Amit Shah.
