In an emergency ICJ hearing on May 15, Indian representatives said Jadhav's death sentence last month followed an "unjust" trial in a Pakistani military court and that Islamabad failed to respond to New Delhi's demands for information about the case.
The UN court said Pakistan should not carry out the death penalty on Kulbhushan Jadhav pending the outcome of a case filed by India alleging that Pakistan breached his right to consular assistance following his arrest a year ago.
As India celebrated ICJ's decision in Kulbhushan Jadhav case, Pakistan responded by saying that it does not accept the United Nations court's jurisdiction in matters of national security.
The death sentence to Jadhav, was awarded by a Pakistan military court on March 3 previous year, last month for espionage and subversive activities.
In April, a Pakistani military court had sentenced Jadhav to death.
Reading out the verdict this evening at The Hague, Netherlands, ICJ President Ronny Abraham said that India has the right to consular access to Mr Jadhav under Vienna convention. ICJ upholds India's right to consular access, put a stay on death execution.
He also ordered Pakistan to inform the tribunal that it has implemented the decision, and stressed that ICJ decisions are binding on all member states. Qureshi said that the issue at hand concerns national stability of Pakistan and ICJ does not have the jurisdiction to rule over such case.
The decision of the International Court of Justice to stay the execution of Kulbhushan Jadav was applauded by the politicians cutting across party lines.
"Proper homework needs to be done in following up this case", the former Minister said.
"Major victory for India #KulbhushanJadhav case". The Court sensed that the clemency period actually meant the country would execute Jadhav even before the matter was heard and settled.
Pakistan keeps on saying that the Jadhav case does not fall in the jurisdiction of the ICJ because it knows the ICJ judgement can not be enforced on Pakistan. "I assure the nation that under the leadership of Prime Minister Modi we will leave no stone unturned to save (him)".
