Paris ? A French judge has ordered three photographers to stand trial for pictures they snapped of the 1997 car crash that killed Princess Diana and her boyfriend, Dodi Fayed, judicial officials said Wednesday.

The order follows a criminal complaint for invasion of privacy filed by Dodi Fayed’s father, Egyptian-born billionaire Mohamed Al Fayed, the officials said, speaking on condition of anonymity.

Diana, Dodi Fayed, and chauffeur Henri Paul died in a high-speed car crash in a Paris traffic tunnel on Aug. 31, 1997, as their Mercedes was pursued by paparazzi on motorbikes.

The photographers only will be tried for pictures they took of Dodi Fayed since Diana’s relatives and the British royal family are not plaintiffs in the case, the officials said.

In his decision Tuesday, Judge Bruno Peries dismissed the case against five other photographers who took pictures at the crash scene, the officials said.

The judge identified only Jacques Langevin of the Sygma/Corbis agency, Christian Martinez of the Angelis agency and free-lancer Eric Chassery as having made photos deemed unacceptable.

The trial likely will begin next year.

In a separate case over responsibility for the crash, France’s highest court in April ended years of court battles by dismissing charges of manslaughter against the photographers. An investigation concluded that Paul had been drinking and was driving at high speed.

Al Fayed, owner of Harrods department store in London, has contested French court findings exonerating the photographers from responsibility for the crash.

Al Fayed has suggested the deaths were a murder conspiracy plotted by people who disapproved of Diana’s relationship with his son.
