There may be legal action in French Polynesia over last month's assembly resolution asking for France to reinscribe the territory on the UN decolonisation list.
A member of the ruling coalition currently in detention, Clarenntz Vernaudon, says he had written to the assembly president to state that he was against the resolution.
When the vote was taken, the assembly president purported that Mr Vernaudon's proxy vote was in favour, giving the government 30 votes in the 57-member assembly.
Mr Vernaudon's lawyer has told local media that this may call into question the legality of the vote.
Last month, the opposition called for the high commissioner to seek to annul the resolution because the outcome of the vote couldn't be verified as it was done by raised hands.
The high commissioner, Richard Didier, has told local television he cannot act because the assembly has sent no documents to check if the process was proper.
