Hours before the execution of the Bali Nine pair, the lawyer for Australian citizens Andrew Chan and Myuran Sukumaran has filed a legal challenge before an Indonesian constitutional court.

A report published in The Guardian has claimed that a court in Indonesia has accepted a legal challenge brought in on behalf of the two Australians on death row, by the lawyer representing the pair due to be executed on 28 April midnight.

The appeal has raised hopes that their execution may get delayed amid increasing international interest in the fate of the death row convicts.

"For the Bali Nine (pair), we have the constitutional court appeal, we have the registration number and we have the schedule fixed on 12 May," said Leonard Arpan, lawyer for Myuran Sukumaran and Andrew Chan.

"We keep hoping that this ongoing legal process will be respected." The story is still developing and more updates on the appeal is expected.

Despite a last ditch effort of appeals from Australian foreign minister for a stay on the execution, Indonesia seems determined to execute the nine convicted drug smugglers on Tuesday midnight.

An Al Jazeera report stated that the families of the Australian convicts "paid an anguished final visit to their loved ones on Tuesday, wailing in grief as ambulances carrying empty white coffins arrived at their prison."
