Staff and lawyers were evicted from the Court House for about two hours.
Court officials say the threat was issued before 8am today.
An anonymous caller had called the officer of the Chief Justice notifying them of a possible bomb threat.
At 8am, all staff were evicted from the Court House and the gate closed with the guards turning away the public.
At around 9:30 personals from the PNGDF’s Explosive and Ordinance Division arrived to visibly check the area.
