"Now, I am going to file a fresh Mercy petition before the President of Pakistan on Thursday, June 25, and from my side I am confident that I will not allow Pakistan government to hang an innocent person only on the basis that he is Non-Muslim or an Indian national," Ansar Burney said.
"How a court, if there is any justice in that court, can punish a person to hang without providing him any lawyer and in a case where the prisoner already spent 18 long years in a death cell that is more than a life sentence?" Burney added.
Earlier on Wednesday, Sarabjit Singh's petition to review his death sentence was rejected by Pakistan''s Supreme Court.
Sarabjit has been on death row in Pakistan since he was convicted for his alleged involvement in four bomb blasts in 1990 in different cities of Pakistan's Punjab that killed 14 people, but Sarabjit's family insists that he was wrongly convicted.
The civil rights activist condemned the decision of the Supreme Court on the review petition.
