PARIS — A court in France ruled on Tuesday against a celebrity chef who sued the Michelin Guide after its reviewers stripped his restaurant of one of its treasured three stars.

The chef, Marc Veyrat, was outraged when La Maison des Bois, his restaurant in the Haute-Savoie area of France, which borders Switzerland and Italy, received a two-star rating in the 2019 guide, down from the top rating of three stars the previous year.

Most chefs would be overjoyed at two Michelin stars, a status that can vault a restaurant from obscurity and dire financial straits to international acclaim and wealth.

But Mr. Veyrat, 69, sued the guide in September in an effort to compel the dining guide to turn over reviewer notes that led to the downgrade, as well as the receipts from their meals.
