The Supreme Court on Wednesday ordered the release of AG Perarivalan, who has served over 30 years of life term in the Rajiv Gandhi assassination case. The change in the sentencing comes 31 years after the former Prime Minister was killed in a suicide bombing attack by Liberation Tigers of Tamil Eelam (LTTE) militants on May 21. AG Perarivalan was released days before Gandhi's 21st death anniversary after a bench headed by Justice L Nageswara Rao invoked its extraordinary power under Article 142 to grant relief to Perarivalan.
