Pakistan's response came after India, on August 29, had asked for "immediate, effective and unhindered" consular access to the former navy officer.
PM Imran Khan told a rare joint sitting of Pakistan's Parliament on August 6 that he will raise the Kashmir issue at every forum.
The JKPM official told this newspaper that Faesal was to fly to Turkey from where he was to reach ICJ in The Hague, Netherlands, to file the case.
On Thursday, India sent a communication to Pakistan making clear its position that the consular access must be "unimpeded" and should be in the light of the ICJ judgement.
Jadhav, 49, a retired Indian Navy officer, was sentenced to death by a Pakistani military court on charges of "espionage and terrorism" in April 2017 following which India had moved the ICJ.
Making a statement in Rajya Sabha, the EAM said the verdict of the International Court of Justice is not only a vindication for Jadhav but also for all those who believe in the rule of law.
The International Court of Justice’s verdict in the Kulbhushan Jadhav case comes at a time when India-Pakistan relations are in deep freeze.
The ICJ ruling in favour of India in the Kulbhushan Jadhav case is built on India’ main contention that Pakistan violated the Vienna Convention by denying consular access to Jadhav.
Similar celebrations were organised at the Silver Oak building at Powai, where Jadhav’s family was residing, by workers of local Congress MLA Naseem Khan.
The observation of the ICJ that the Pakistani authorities have violated the provisions of the Vienna Convention is also a big moral victory for the Indian legal team and the authorities.
Pak’s own admission about the functioning of its military courts seems to have worked against it in the Jadhav case at The Hague
In its 42-page ruling, the court ruled that Pakistan had "breached" the Vienna Convention, which gives countries the right to consular access when their nationals are arrested abroad.
The Foreign Office reiterated that Jadhav entered Pakistan "without a visa on authentic Indian Passport with a fake alias Hussain Mubarak Patel".
The Indian PM said that he is sure that Jadhav "will get justice" and his government will "always work for the safety and welfare of every Indian".
The case began on March 2016 when Jadhav, a former Indian Navy officer, was arrested by Pakistani authorities.
