Nauru's chief justice and only magistrate - both Australian citizens - have reportedly been sacked and deported from the country.
The ABC reports Nauru's president Baron Waqa fired resident magistrate and supreme court registrar Peter Law on Sunday.
Mr Law says he was deported on the first plane after the sacking and says Mr Waqa's actions are clearly in contempt of court.
The ABC says Chief Justice Geoffrey Eames had intervened by issuing an injunction against Mr Waqa's deportation of Mr Law, but that was ignored, and the Chief Justice's visa was revoked, preventing him from returning to Nauru.
Mr Law says the injunction specified the various authorities, including the airlines and the police.
