Three paparazzi who took pictures of Princess Diana and Dodi Al Fayed on the night of their fatal car crash will be retried for breaching privacy laws.
The pictures of Princess Diana and Dodi Al Fayed were never published
France's top appeals court has ordered a partial review of the case of photographers Jacques Langevin, Christian Martinez and Eric Chassery.
They were originally acquitted of breaking privacy laws in a November 2003 ruling by a lower court.
They were also cleared in a later appeal in September last year.
The photographers took pictures of the couple as they left the Ritz Hotel in Paris where they were staying and after the crash that killed them in a tunnel near the river Seine as they lay in their Mercedes.
In September last year, the Paris appeals court found that a crashed vehicle on a public highway was not in a private area.
But on Wednesday, the Cour de Cassation asked the Paris appeals court to review the part of its decision related to the couple's car, saying it was a mistake not to consider the Mercedes a private space.
That decision only concerned three photos of the crash taken in the car.
The lower courts had concluded that the photos of Diana and Dodi leaving the Ritz did not constitute invasion of privacy because the couple knew they would be photographed.
The case will now be sent back to the Paris appeals court, where a new panel of judges will hear arguments from both sides.
The three men face up to a year in jail if they are found guilty of breaking privacy laws.
The main investigation on the causes of the accident was closed in 2002, putting an end to formal manslaughter inquiries brought against nine photographers and a press motorcyclist.
