The French High Commission and the opposition in French Polynesia have launched legal action to block the government's enquiry into the effects of nuclear tests.
The newspaper Les Nouvelles de Tahiti is reporting the French state and the opposition Tahoeraa huiraatira party have lodged appeals seeking to suspend the enquiry.
The appeal is based on a different interpretation of the statutes which outline the circumstances in which the territorial assembly can convene a commission of enquiry.
The State is contesting the ruling coalition's decision to set up the enquiry panel alongside the existing judicial system.
The opposition of former president Gaston Flosse wants the enquiry limited to a given time-period and geographical location.
