Pakistan could challenge Kashmiri separatist Afzal Guru's execution in the International Court of Justice (ICJ) in the Hague.
The ministry of Kashmir affairs asked the Foreign Office to take Guru's case to ICJ on the ground that he was not given a fair trial.
According to the Express Tribune, minister for Kashmir affairs and Gilgit-Baltistan Barjis Tahir formally asked the foreign affairs ministry to complete all the formalities to take up the execution of Guru to the international court, seeking justice for him even after his death.
Indian government executed Guru in the Tihar Jail in New Delhi on February 9, 2013 for allegedly masterminding the attack on the Indian Parliament in 2001.
The execution had sparked criticism and raised many questions from across the world over the fair trial by the Indian authorities, the report said.
Tahir said the Indian courts convicted and subsequently hanged Guru without having ample evidence of his involvement in the attack on parliament, the report added.
