Jadhav, 45, was sentenced to death by a Pakistani military court in April.
"The ICJ has written a letter to Pakistan informing us of their decision," the attorney general said.
"India had adopted the stance that the matter was one of life and death, but Pakistan had stated that the ICJ is not a court of appeals."
"The ICJ is supposed to conclude whether or not Jadhav can receive consular access, for which a time period of two to three months is more than enough to file a response," he said.
In a hearing of the case on May 18, a 10-member bench at the The Hague-based ICJ restrained Pakistan from executing Jadhav.
Pakistan claims its security forces arrested him from its restive Balochistan province on March 3 last year after he reportedly entered from Iran. However, India maintains that he was kidnapped from Iran where he had business interests after retiring from the Navy.
