If you have ever gotten into an argument with your boss about how a sick leave is totally warranted after a night of heavy weekday drinking, don't worry, a German court is here to back you up. In a bizarre judgment, the state court in Frankfurt on Monday ruled that hangovers are an illness. Here are more details. The Frankfurt court delivered the verdict while hearing a case against food supplement distributor for selling an anti-hangover drink. It was said the distributor's shots and drink powders to mix with water were making illegal health claims, according to Agence France-Presse. Reportedly, the firm violated a ban on ascribing the ability to prevent, treat or heal illnesses on food products. The court ruled, Information about a food product cannot ascribe any properties for preventing, treating or healing a human illness or give the impression of such a property, It added, By illness, one should understand even small or temporary disruptions to the normal state or normal activity of the body. These disruptions included tiredness, nausea, and headaches the firm's anti-hangover products claimed to fix. Associated Press reported that the court rejected an appeal against a similar verdict delivered by a lower court. Interestingly, the judgment comes on the heels of the annual beer-soaked festival, Oktoberfest, in Munich. During the 16-18 day fest, revelers fill the streets of Munich wearing the traditional dirndl and lederhosen and large quantities of beer is consumed. The festival ends on October 6.
