New Delhi, Feb 18 (ANI): The Supreme Court on Tuesday commuted the death sentence of three men convicted of killing former Prime Minister Rajiv Gandhi to life in prison. The convicts, Santhan, Murugan and Perarivalan, had petitioned against their death sentence, arguing that there had been an exceptional delay in a decision on their mercy plea. A bench headed by Chief Justice P Sathasivam delivered the judgement on the mercy plea. The Centre had earlier opposed the plea by arguing that the convicts did not go through torture, agony and dehumanizing experience during pendency of the mercy pleas. The verdict drew mixed reaction from poltical leaders.
