From what has been written since 2 years on the French media the case is a bit more complicated , it was the 3rd similar run with same aircraft , same crew , same pax and same "fixer", who dressed as a pilot (with 3 stripes) to appear to be s crew member.
The whole judicial question turned around if it was a commercial flight ( operator responsibility) or a private flight( PIC responsibility.) Apparently the judge ruled it was a private one .
