French Polynesia's Court of Appeal has revisited the case of the five people sentenced to prison terms over the 2007 Air Moorea crash in which 20 people died.
Four months ago, they had their sentences quashed by France's highest court, which found that not all relevant matters had been considered in determining their sentences.
It sent the case back to Papeete where a newly constituted Court of Appeal has heard the prosecution asking for the jail terms to be upheld.

Its verdict is expected on 1 September.
Among those found responsible for the crash is the former director of Air Moorea, Freddy Chanseau, its technical director Jacques Gobin and the head of the French Polynesian Government's air safety unit, Andriamanonjisoa Ratzymbasafy.
The accident occurred when a steering cable ruptured shortly after take-off.
The case was first heard in the Criminal Court in 2018, with involuntary homicide charges laid against the men, at the insistence of the victims' families.
