Lawyers acting for French Polynesia's veteran politician Gaston Flosse and his son Reginald have asked for the charges against them to be dropped.
Last year, the former president had been charged with complicity in attempted corruption while Reginald Flosse has been charged with attempted corruption.
The two had been alleged to have forged management papers for a house which Flosse sold in Paris in 2010 for more than $US6 million.
According to Tahiti-infos, their lawyers have now asked for the investigators to drop the charges, saying they don't stand up.
A decision is expected next month.
Flosse had insisted that he had ceased to be a co-owner of the house as he was asked to repay the public purse the money misspent on phantom jobs benefitting his political party.
