The Rawalpindi bench of the Lahore High Court set aside the appeal filed by Aqeel Ahmed alias Doctor Usman, a former personnel of the army's Medical Corps who was convicted for the 2009 attack.
During the hearing, Justices Mazhar Iqbal and Ibadur Rahman Lodhi pointed out that the federal government had not yet decided on implementing death sentences. The appeal would be heard after the government makes a decision on the issue, they said.
Following this, Usman challenged his death sentence in the Lahore High Court. He contended that he was sentenced without being given an opportunity to defend himself.
Some 10 heavily armed militants wearing suicide vest had stormed the General Headquarters in 2009. Eleven soldiers were killed in the attack.
A moratorium on executions imposed by outgoing President Asif Ali Zardari expired recently. The PML-N government had decided to execute four death row prisoners, including members of banned terror groups, later this month.
