The second round of written reply by India in the case was in response to the submissions by Pakistan in the ICJ on December 13 last year, the foreign ministry said.
India had moved The Hague-based ICJ in May last after Indian national Kulbhushan Jadhav, 47, was sentenced to death by a Pakistani military court on charges of espionage and terrorism. A 10-member bench of the ICJ on May 18 had restrained Pakistan from executing Kulbhushan Jadhav till adjudication of the case.
"In keeping with the Order of the International Court of Justice of 17 Janaury 2018, India today submitted its reply in the court in the case of Kulbhushan Jadhav," the foreign ministry said.
It said India remains committed to make all possible efforts to "secure and protect" the rights of Kulbhushan Jadhav.
Following an order by the ICJ, India had filed its written pleadings in the case on September 13, 2017 and Pakistan submitted its "counter memorial" on December 13 last.
"Today, India filed its Reply to Pakistan's submissions to the court. Pakistan has been given time till July 17 by the court to file its response (Rejoinder)," the foreign ministry said.
Pakistan claims that its security forces arrested Kulbhushan Jadhav from restive Balochistan province on March 3, 2016 after he reportedly entered from Iran.
However, India maintains that Kulbhushan Jadhav was kidnapped from Iran where he had business interests after retiring from the Navy. Kulbhushan Jadhav's sentencing had evoked a sharp reaction in India.
India had approached the ICJ for "egregious" violation of the provisions of the Vienna Convention on Consular Relations, 1963, by Pakistan in Kulbhushan Jadhav's case.
Pakistan has repeatedly denied India consular access to Kulbhushan Jadhav on the grounds that it was not applicable in cases related to spies.
