"Pakistan's security is so important and we have to maintain our fundamental sovereign right", Aziz said. Calling the ICJ jurisdiction, "Pandora's Box", he said that Pakistan must be happy that India went to the ICJ for a single man's life as they could now raise a variety of issues, particularly about Kashmir in an worldwide forum, something to which India has always objected.
The ICJ ordered Pakistan to stay Jadhav's execution over allegations of spying until its final decision on India's petition to annul his death sentence.
Addressing a press conference here, Aziz said that when it comes to cases involving the death penalty, the global court has always given a stay order.
Aziz also rejected all such reports stating that Indian businessman Sajjan Jindal's visit to Pakistan last month was focused on seeking reprieve for Jadhav.
The ICJ has asserted its jurisdiction over the case of the 46-year-old former Indian Navy officer while noting that the circumstances of his arrest remain disputed. Pakistan's Geo News reported that announcement was made by Ashtar himself, saying that the country's defence against India's case before the ICJ was prepared by the government in consultation with all stakeholders. He said the ICJ had not decided on consular access either and had only intimated that the matter would come under discussion.More news: Fighter Jets Scrambled After 'Disturbance' on American Flight

The Adviser said that Kulbhushan Yadav was using fake passport in Pakistan and was involved in numerous subversive activities to destabilize Pakistan.
ICJ had previously stayed Jadhav's death sentence who was trialed in a military court and confessed to being tasked by RAW to conduct terror activities in Pakistan.
The International Court of Justice on Thursday blocked the execution of Jadhav, sentenced to death by a Pakistani military court on charges of spying and subversion.
According to PTI, a case has been filed against the Indian national under Article 14 of the Pakistan Foreign Act.
"We will go with a strong team in the next hearing", Aziz added. After the verdict yesterday, Foreign Minister Sushma Swaraj tweeted, "I assure the nation that under the leadership of Prime Minister Narendra Modi, we will leave no stone unturned to save Kulbhushan Jadhav".
