Vanuatu's opposition parties have called for the resignation of the Electoral Commission over the long delay in releasing the official results and the mistakes which followed.
Official results were released almost three weeks after the election.
An error in the number of votes cast in the Santo rural seat saw Vatambae Reme from the opposition Melanesian Progressive Party as the successful candidate, winning by 4-hundred and one votes.
The Union of Moderate Parties disputed the results and a recount showed UMP candidate Jean Alain Mahe having the numbers to retain the seat.
The Commission's Chairman, Sethy Regenvanu, has described the incident as a mystery.
He says his staff recounted the votes cast for Mr Reme five times and cannot explain the reversal.
