The European Union has upheld France's right to ban Red Bull. On Friday the European Court of Justice ordered France to lift its ban on the drink unless it could prove any health risks. The court also said, however, that the French government did have a right to ban Red Bull.

French scientists claim that the levels of caffeine in the drink pose a real risk to public health if drunk to excess. France consequently refused to authorise its sale, a move which was challenged by the European Commission when manufacturers complained that it was inhibiting imports.

While other toxicology experts around Europe had concluded that the caffeine levels in Red Bull are safe, the court ruled that France had a right to ban the drink on the advice of its own experts.

One can of Red Bull contains 80mg of caffeine, the equivalent of one cup of coffee. The drink is sold in around 100 countries, with only France and Denmark having banned it. An EU ruling which comes into force later this year means that Red Bull and other energy drinks will have to carry "high caffeine content" warnings.
