A top French judge in French Polynesia, Jean-Bernard Taliercio, has been suspended following a probe begun by the judicial service commission two years ago.
Media reports in Papeete say Mr Taliercio is alleged to have had friendships inappropriate for a judge and having acted in real estate affairs incompatible with his position.
The reports say questions have been raised about links to some businesspeople and a former president, Gaston Flosse, as well as the management of some his court cases.
Mr Taliercio says he is the victim of a plot while his lawyer says moves are afoot to have him removed to protect the interests of others.
He had been a judge in Papeete for 21 years.
