Indian Foreign Minister Sushma Swaraj welcomed the ruling and said in a Tweet that it was "a great relief to the family of Kulbhushan Jadhav and people of India". He said Pakistan's argument before the ICJ and its refusal to accept its jurisdiction betrays a mindset of disrespect to the Vienna Convention which Pakistan has brazenly violated.
Jadhav is the fourth instance of an India-Pakistan dispute being heard by the International Court, but is the first time that a hearing has taken place under the glare of the press and social media and ensuing public scrutiny.
In April, a military court sentenced him to death for alleged involvement in spying and subversive activities.
In court on Monday, India called Jadhav's trial a "serious miscarriage of justice" because he wasn't allowed to see Indian diplomats or choose his own defense lawyer.
"This court unanimously decides that Pakistan shall take all measures at its disposal so that Kulbushan Jadhav is not executed pending a final decision of this court in the matter". Kulbhushan Jadhav is a former Naval Officer who went to Pakistan as Spy.
Talking to ANI, Jadhav's childhood friend Arvind Singh said he was hopeful that the International Court of Justice (ICJ) would give a verdict in India's favour.
In the LaGrand case, the court called on the USA to "take all measures at its disposal" to ensure that Walter LaGrand (on death row at the time) was not executed pending a final decision of the court in the proceedings instituted by Germany and inform it of all the measures taken in implementation of the order. Pakistan had defended its position by terming New Delhi's story a far-fetched one as criminal cases did not fall within the purview of the Vienna Convention.
The decision of Kulbhushan Jadhav's death penalty was read out by the President of the ICJ, Ronny Abraham.
Pakistan had argued that it didn't provide Consular access to Jadhav as India refused to provide any inputs on him.
India: Jadhav was abducted from Iran in 2016, and that there has been no credible explanation by Pakistan how he was found there.
Pakistan says it has a "confession video" of Mr. Jadhav saying he spied for India.
- Relief by way of "immediate suspension of the sentence of death awarded to the accused".
Jadhav's case is the latest flash point in the tensions between Pakistan and India.
"Pakistan has entered a revised declaration under Article 36 (2) of the Statute of ICJ (International Court of Justice) on 29th March, 2017".
India is represented by its "Agent" Deepak Mittal, who is the head of the Pakistan division in the external affairs ministry and the case is argued by its lead attorney Harish Salve.
