India on Thursday said the International Court of Justice's decision on Kulbhushan Jadhav is an "essential first step" in ensuring justice for him.
At the hearing India heavily slammed Pakistan for not revealing any evidences against Kulbhushan Jadhav in public.
It wants the ICJ to decide whether Pakistan has broken the convention and worldwide human rights law.
The International Court of Justice instructed Pakistan to take all "necessary measures at its disposal" to ensure that Jadhav was not executed pending a final decision by it.
Judge Ronny Abraham, President of the court, will read the decision, it said. It asked Pakistan to "take all measures" to hold off the execution and allow consular access to Mr Jadhav.
ICJ on consular notification and accessThe Court then turns to the question whether the rights alleged by India are at least plausible.
Pakistan, however, rejected the plea on the ground that India had no right to invoke the jurisdiction of the UN's highest court because the Vienna Convention does not provide for matters relating to spies, terrorists and those who indulge in espionage.
India claims Mr. Jadhav was kidnapped from Iran, arrested and sentenced based on "concocted charges" and that the sentencing was not duly conveyed to India. He instead said that India was using the court as the "scene of political theatre".
Earlier, Zakaria said at the weekly press briefing said India was trying to portray Jadhav's case "as a humanitarian issue to divert the world's attention from his role in fomenting terrorism" inside Pakistan.
The court, formally known as the International Court of Justice, is the U.N.'s court for hearing disputes between states and its rulings are binding.
Pakistan, which announced the sentence on Jadhav on April 10, claims its security forces arrested him from its restive Balochistan province on March 3 past year after he reportedly entered from Iran.
The ICJ was set up in 1945 to rule on disputes between nations in accordance with worldwide law. The two countries last faced off at the ICJ 18 years ago when Islamabad sought its intervention over the shooting down of its naval aircraft.
The Vienna Convention has been a frequent subject of disputes at the ICJ, often in cases involving the United States.
India and Pakistan have routinely accused one another of sending spies into their countries, and it is not uncommon for either nation to expel diplomats accused of espionage.
