Pakistani prison officials have missed Tuesday's court deadline to explain how they would hang a paraplegic man.
Abdul Basit is paralysed from the waist down and uses a wheelchair after an illness he contracted while in prison.
He was convicted six years ago of murder but maintains his innocence. He was to be hanged in Lahore last month but this was postponed. A petition for his pardon was dismissed.
Hanging him would constitute cruel and degrading treatment, his lawyers say.
They add that this is prohibited under Pakistani and international law.
Pakistan has executed more than 200 people since reintroducing the death penalty in December 2014.
At the time the government said it was a measure to combat terrorism after the Taliban massacred more than 150 people, most of them children, in a Peshawar school.
Pakistan's jail manual gives no instructions on how to execute disabled prisoners.
A high court judge had told prison officials they had until 1 September to come up with specific steps if they were to be allowed to proceed with the execution of Mr Basit.
The BBC's Shaimaa Khalil says Mr Basit remains on death row but his sentence has effectively been stayed until the jail authorities come up with a clear plan for how they will execute him.
