The former head of French Polynesia's GIP militia Rere Puputauki has been in the appeal court challenging last year's conviction for abuse of trust.
He had been given a two-year prison sentence over a failed property deal, with the prosecution now asking again for him to be jailed for two years.
Puputauki was found to have spent about $US170,000 the contributions made by about 30 others towards the project to build a property.
He was found to have closed the project accounts and taken out the money, but only two of those who lost their money lodged a complaint.
His lawyer wants the charges to be dismissed.
The appeal court is expected to give its ruling on 27 September.
