Pakistan's Foreign Affairs Advisor Sartaj Aziz told the media that Pakistan's counsel had courageously presented their stance in the ICJ, which stayed the execution of Jadhav - in a let-down for Islamabad.
"Pakistan shall take all measures at its disposal to ensure that Mr Jadhav is not executed pending the final decision in these proceedings", said the court's president Ronny Abraham. The circumstances of Jadhav's arrest remain disputed, Judge Abraham said while reading out the world court's verdict.
Meanwhile, Pakistan said the ICJ's decision has not changed the status of Jadhav's case in any manner.
Pakistan claimed that the former Indian Navy officer confessed in a video that he was involved in spying and terror activities in Balochistan, a charge rejected by India.
"The real face of India will be exposed before the world", Foreign Office spokesperson Nafees Zakaria said.
He also ordered Pakistan to inform the tribunal that it has implemented the decision, and stressed that ICJ decisions are binding on all state members.More news: Awards for Celtic's Brendan Rodgers and Scott Brown
The interim order issued on Thursday is nominally binding, but there have been cases in the past when countries have disregarded such stays of execution.
India approached the ICJ on May 8 asking for a stay on Jadhav's death sentence, in addition to granting three other provisional measures it has sought against Pakistan, pending the court's decision on the merits of the case.
In an obvious reference to Jadhav's trial in a Pakistani military court, Jaitley said any form of judicial proceeding which is conducted in secrecy and in darkness and is not open for any public gaze, lacks the very appearance of justice.
As per reports, 11 judges today agreed with India's stand that there is urgency in the case, and noted that Pakistan had given no assurance that Mr Jadhav would not be executed till its verdict.. "The United Nations should also take a serious note of it".
Pakistan argued before the ICJ that it does not have jurisdiction in the case as it was related to its national security; it also insisted that a person convicted of terrorism can not be granted consular access. The court considers it has prima facie jurisdiction in the case.
With just a day to go for the expiry of a 40-day deadline to challenge the death sentence given to Kulbhushan Jadhav, Indian officials said on Friday they do not know if Pakistani military authorities are even considering an appeal submitted by the former Indian navy officer's mother. Also, India's allegations against Pakistan are related to the terms of the Vienna Convention and hence, ICJ does have jurisdiction, regardless of the 2008 bilateral agreement between India and Pakistan.
