The bachelor, Mark Fournier, wore the uniform on December 3, 2011 to a party at Val Thorens ski resort. Wearing a Nazi uniform and insignia is illegal in France.
A former British MP who attended the party, Aiden Burley, was dismissed after pictures of the party leaked out to in the press.
Here’s a tweet containing one of the photos:
Fournier is charged with wearing the uniform of an organization guilty of crimes against humanity and the hefty fine is the maximum amount for that offense.
"English law does not consider the wearing of a Nazi uniform to be, in itself, a crime. We can see that from the conduct of Prince Harry," said Fournier's lawyer, Michel Roubaud.
"My client's behavior was not ideologically motivated. It was organized by his best man, the MP, and took place in the context of a boozy stag party. He asked his MP friend if it was against the law to wear a Nazi uniform in France and he told him 'no.'"
"You cannot classify these acts as a schoolboy joke," said Olivier Fernex de Mongex while speaking on behalf of an organization that represents Holocaust survivors.
