The Supreme Court on Wednesday sought the CBI's response to a plea seeking the recall of its 1999 judgement upholding the conviction of seven accused in the Rajiv Gandhi assassination case. A bench of Justice Ranjan Gogoi and Justice R. Banumathi sought the Central Bureau of Investigation's response on a plea by A.G. Perarivalan- one of the seven convicts undergoing life imprisonment for his role in the conspiracy leading to the assassination of the former Prime Minister Rajiv Gandhi. In his application, Perarivalan has said that he is languishing in jail for the past 26 years. The Apex court has asked CBI to respond to the plea within three weeks and has listed the matter for hearing on February 21.
