Jadhav's case is being tried in military courts.
Pakistan on Thursday denied any deal with the Indian government on Kulbhushan Jadhav, who has been sentenced to death by a military court on charges of espionage and terrorism in April 2017.
"The action on Kulbhushan will be taken as per the law. There will be no deal. Absolutely, no question about that," said Foreign Office spokesman Muhammad Faisal in a weekly press briefing.
Earlier, there were reports about an amendment in the Pakistan Army Act to implement the International Court of Justice's condition to allow Kulbhushan to file an appeal in a civilian court.
However, the Pakistani military rejected such reports.
Kulbhushan's case is being tried in military courts and the Army Act forbids such individuals or groups from filing an appeal or seeking justice from a civilian court.
On July 17, the ICJ ordered Pakistan to grant consular access to Jadhav and also continued stay on his execution, as well as "effective" review of the death sentence.
