(BBC) India's Supreme Court has ordered the release of one of the convicts involved in the 1991 murder of former prime minister Rajiv Gandhi.
AG Perarivalan was in jail for over 30 years. In 1998, he was sentenced to death, but it was later commuted.
Arrested at 19, Perarivalan was convicted for procuring batteries that were used in the bomb to kill Gandhi.
Gandhi was assassinated by a female suicide bomber as he addressed an election rally in Tamil Nadu state.
Gandhi's killing was widely seen as retaliation for his having sent Indian peacekeepers to Sri Lanka in 1987 when he was prime minister.
Perarivalan was a member of the Liberation Tigers of Tamil Eelam (LTTE), a rebel group fighting for a separate Tamil state in Sri Lanka. The rebels were finally defeated by Sri Lankan troops in 2009.
On Wednesday, a three-judge bench of the Supreme Court invoked a section of the Indian Constitution that grants it extraordinary powers "for doing complete justice in any cause" to release Perarivalan, one of the seven convicts in the case, considering that he had been in jail for over 30 years.
Over the years, governments in Tamil Nadu state had asked for Perarivalan and the other convicts to be released.
In 2000, the state governor had commuted the death sentence of Nalini, a female convict in the case, and in 2014, the Supreme Court had commuted the death sentences of all the others on account of an 11-year delay in deciding their mercy petitions.
