Alarm has been raised over reported moves by Papua New Guinea's government to remove the Chief Justice, Sir Salamo Injia, and other judges.
A former Chief Justice and the previous Attorney General, Sir Arnold Amet, says discussions are being held by senior officials to make these changes.
He warns against the move, saying attempts to tamper with the judiciary will destroy the foundations of PNG's democratic institutions.
"And there are very explicit, stringent provisions in the constitution and the organic law of processes and procedures on how to deal with institutions and leaders of institutions, should there be the need to do so and it's not capable of being arbitrarily usurped."
Sir Arnold Amet suspects the move is an attempt by the government of Peter O'Neill to affect the imminent ruling of the Supreme Court on the constitutionality of events in parliament which took it to power in August.
