Aziz said the ICJ had given its point of view on Jadhav's case to get consular access.
"Jadhav was sentenced according to the laws of Pakistan after he admitted to entering the country on a fake passport and involvement in terror activities", he told reporters.
Khawar Qureshi said Jadhav's case is more about political point scoring than about the law.
The speaker also said Pakistan would not take any dictation on the issue and will take a decision as per its interests. "By going to the ICJ we may have opened up a Pandora's box", he wrote. It added that it indeed has jurisdiction in the case, superseding a 2008 agreement between India and Pakistan.
"The ICJ gave no verdict regarding consul access", he added. The ICJ's decisions are considered legally binding on both India and Pakistan. He also rejected any link between Jindal's visit and the Jadhav case.
Aziz, however, maintained that Qureshi had "courageously" presented Pakistan's case in the court, the Nation reported.
Sadiq was further reported to have said that Pakistan should be united and not play politics on the Jadhav issue.
According to PTI, a case has been filed against the Indian national under Article 14 of the Pakistan Foreign Act. The International Court of Justice (ICJ) has stayed his execution.
Responding to a question on why no judge was sent on the day of the ICJ hearing, he said the government could not appoint one within a short period of five days.
