The Indian government on Wednesday filed an appeal with Pakistan seeking a review of death sentence awarded to Indian Kulbhushan Jadhav.
However, Janjua contended Jadhav was not covered under a bilateral agreement on consular access as he was a "spy".
"Lulzsec India" - a team of 11 hackers had shot to limelight after they brought down 30 Pakistani Government websites after the Govt announced death penalty to former Indian Navy Officer Kulbhushan Jadhav, as a mark of protest.
"I humbly request appropriate and capable authorities to intervene in the matter and make sure that Mr. Kulbhushan Jadhav doesn't get punished for the act which he never committed", the petition added and it also urges United Nations to look into this matter. Pakistan was also requested to facilitate visas for the mother and father of Jadhav, who has been charged with carrying out espionage activities.
Bambawale asked Janjua to provide access to Jadhav to further pursue his case, including launching an appeal against his death sentence, local media reported. He had told reporters after the meeting that he had demanded a certified copy of the chargesheet and judgement so that India could appeal against the sentence.
"All the hacking in Pakistan was part of our operation "Justice for Kulbhushan Jadhav".
Pakistan has denied India's request for consular access to Jadhav over a dozen times in the last one year.
During the meeting, a well-placed source told Pakistan Today, the high commissioner again sought consular access to Indian spy Kulbushan Jadhav. They wish to travel to Pakistan to meet him and also to personally file the petition and appeal.
Jadhav was earlier arrested on March 3 previous year from the tensed Balochistan province.
This is the second time that high commissioner Bambawale has met Janjua since the sentence was announced.
The Pakistan Foreign Office said due judicial process was followed during Jadhav's trial and that he was provided with a lawyer in accordance with the Constitution of Pakistan.
The Pakistan Army had earlier ruled out consular access to Jadhav, saying he is not eligible for it as per the laws.
