To this, the Centre had filed a petition to the Supreme Court, challenging the state government's authority to order the release, especially when its appeal against the commutation of death sentence of the three convicts was rejected.
Early in February, the court had commuted the death penalty of Rajiv Gandhi's assassins to life imprisonment due to delay in deciding the mercy plea.
To this, the Centre in March had said the TN government's decision was selective and was violating Article 14 of the Constitution. It also accused the state government for not considering several other factors such as "as many as 18 innocent lives were lost and over 200 people were injured as a result of the human bomb". The Centre had said the action of the state was in "derogation and breach of Article 21, rights of the family and victims".
Terming the decision as "hasty and malafide", the Centre had told the Apex court that it would now intervene in the same.
