PARIS (REUTERS) - A French court on Wednesday (Sept 19) threw out an appeal by celebrity magazine Closer against a 2017 ruling that it invaded the privacy of Prince William's wife Kate, the Duchess of Cambridge, when it published topless photos of her in 2012.

Mr Laurence Pieau, an editor of Closer's French edition, and Mr Ernesto Mauri, the chief executive of Italian publisher Mondadori, the magazine's owner, were each handed maximum fines of €45,000 (S$72,000) in September last year.

Closer magazine, a weekly round-up of gossip about the rich and famous, was also ordered to pay €100,000 in damages to William, second-in-line to the British throne, and his wife.

Lawyers for the two men argued the fines were excessive for a privacy case, French media reported.

The Versailles appeals court found that the fines imposed by the initial ruling were "fair and proportionate", court documents showed.

Closer published a series of topless photos of Kate taken as she relaxed on the balcony on a chateau in south-eastern France's Luberon region.

Closer magazine's lawyers had sought in the original trial to justify publication of the photos on public interest grounds, saying they disproved rumors circulating at the time that Kate might be anorexic.
