Hearing has begun. India will present its case first.
The Indian national, who had been arrested on March 3 previous year and sentenced to death on allegations of espionage and subversive activities, had been framed on the basis of confessional statements extracted from him when he was in Pakistan's military custody, Salve added. Pakistan was to respond later Monday.
"India has been unable or perhaps more accurately unwilling to provide an explanation for this passport which is the most obvious indication of covert and illegal activity", he said.
Battling Pakistan in the UN's highest judicial body, India said the situation was grave and urgent, prompting it to approach the court "at such short notice".
"We gave a free trial to a terrorist like Kasab and Pakistan hasn't even revealed in what condition Kulbhushan is in".
Treatment told the court that Jadhav's tape was doctored.
India is seeking relief in the form of immediate suspension of the death sentence. He was accused of spying for Indian intelligence agency, the Research and Analysis Wing, and aiding separatist elements in restive Balochistan. "We will fight for his justice", he added. Pakistan has not provided the chargesheet, any documents on the case despite repeated requests. "It is unlikely that decision will come today", CNN-News18 quoted Harish Salve as saying. India has stated its case in the morning.
Senior Pakistani government officials stated that the incarcerated Jadhav's confession is the "crux" of Islamabad's case, Geo News reported.
The legal teams of India and Pakistan have arrived at Hague.
In its submission, Salve had earlier pointed out that the consular pact between India and Pakistan was not relevant as it was not registered with the UN.
"It is clear that Jadhav has been denied of his right to seek legal counsel". Pakistan had later released a video which showed Jadhav allegedly confessing to his crimes.
The hearing will be carried out in two phases.
India also alleged that "it was not informed of Jadhav's detention until long after his arrest", and learned about the death sentence through the media.
■ All requests for consular access to Kulbhushan Jadhav fell on "deaf ears": India. "Kulbhushan Jhadav's case can not be tried in the International Court of Justice", he said.
India has denied he was a spy, and last week lodged a protest at the ICJ in The Hague accusing Pakistan of "egregious violations of the Vienna convention".
Attorney General Ashtar Ausuf will be present for the hearing via a video link.
