Jadhav, who was arrested in Pakistan for espionage and sabotage activities, has been handed down death sentence by the military court, confirmed the Inter-Services Public Relations (ISPR).
A Pakistani military court sentenced an Indian accused of espionage to death on Monday, reports said.
Addressing a full Senate chamber, Aziz had said that the dossier on Jadhav that Pakistan submitted contained mere statements.
Pakistan claims its security forces had arrested Jadhav from the restive Balochistan province on March 3 a year ago after he reportedly entered from Iran.
Pakistan accuses India of helping the separatist movement in Baluchistan, a charge denied by India.
According to Pakistani authorities, Jadhav told judges past year that he was a naval officer who had started doing work for Indian intelligence following a 2001 attack on parliament that India blamed on militants backed by Pakistan.
New Delhi while reacting over death sentence of Yadev said that if the order was carried out (his death sentence), it would be perceived as "premeditated murder".
Pakistan had, however, turned down India's request seeking consular access to Jadhav a year ago due to his involvement in "subversive activities" in Pakistan.
Jadhav, in pursuit of targets set by his RAW handlers, was arrested by Pakistani authorities on March 3, 2016, when he attempted to cross over into the country from the Saravan border in Iran.
Another neighbour, Subrato Mukherjee, said Jadhav and his family have always been very helpful to all the society members and he had even taken Marathi lessons from his parents.
Shortly after his arrest, Islamabad released a video in which he was shown admitting involvement in spying. Pakistan says Jadhav is a commander rank officer in Indian Navy. However, that will not happen, with official sources being quoted by agencies as saying that this is "not the right time" for such a gesture.
However, public opposition to Indian rule remains deep and is now principally expressed through street protests marked by youths hurling stones at government forces. Expressing wrath over Pakistan's decision to execute an Indian national for "spying", India on Monday decided not to release a dozen of Pakistani prisoners, who were to be repatriated on Wednesday after completion of their prison term.
