He said Pakistan has not taken a step so far on the issue.

"We have reached the point that we may have to go to ICJ for consequential direction. Because Pakistan has not moved," Salve was quoted as saying by WION.

''I know the current situation," he said and added, India and Pakistan have had 7-8 exchanges and New Delhi was hoping that via backchannel.

"We will persuade Pakistan to let him go. Even if it is a humanitarian ground, we want him back. Because it has become a big ego problem in Pakistan," he was quoted as saying by the Indian news channel.

Ending all speculations, the International Court of Justice (ICJ), last year, in a 15:1 judgement ruled in favour of India as it passed its verdict in the case related to Indian national Kulbhushan Jadhav, who was sentenced to death in Pakistan on charges of espionage. The international court thus stayed the execution of Jadhav by Pakistan.

The verdict was read out  in a public sitting of the United Nations court  in The Hague.

A Pakistani military court in April 2017 sentenced Jadhav to death on charges of espionage and terrorism.

The International Court of Justice had earlier asked Pakistan to hold off the execution till it reaches its final verdict in the case.

Even as Jadhav, 48, was sentenced to death by a Pakistani military court in April 2017,  following the Indian government's move to the international court, the 10-member bench of the ICJ on May 18, 2017 had given a stay order and 'restrained' Pakistan from executing Jadhav till adjudication of the case.

In its written pleadings, India had accused Pakistan of violating the Vienna Convention by not giving consular access to Jadhav arguing that the convention did not say that such access would not be available to an individual arrested on espionage charges.

India had said the so called trial of Jadhav by a military court in Pakistan was "farcical".

Later in December, 2017, Kulbhushan Jadhav was allowed to meet his wife and mother but the MEA in Delhi had said it appeared Jadhav was “under considerable stress” and “speaking in an atmosphere of coercion”.
