"I convey my regards and welcome him. This judgement is a victory for state autonomy and federalism", MK Stalin said in his statement.

Perarivalan had addressed the media for the first time in three decades during which he thanked his mother for her fight. 

As the verdict has turned heads from across the nation, let's take a look at Article 142 and the notable cases which had got its invocation.

The Supreme Court has on Wednesday invoked its powers under Article 142 of the Constitution and released Perarivalan, who was already on bail.

The court has also noted that Perarivalan's conduct in jail was good, and that he is being discriminated against under Article 14 of the Constitution - the right to equality. 

In her petition, Nalini has highlighted that the Supreme Court has awarded bail to Perarivalan by citing that he had spent more than three decades in prison.

She has expressed her gratitude to Tamil Nadu Chief Minister MK Stalin and for everyone who had extended their support to her struggle.

The apex judicial body has also highlighted that he is entitled to get released on bail, based on the fact that he had spent three decades in jail. 

While passing the order, the court has noted that there was no complaint about his conduct when he was released on parole three times.

He has been taking legal measures to seek a release from the prison and he also had petitioned the Tamil Nadu Governor to grant him amnesty.
