Denomination of a significant judgment of the Court of Justice of the European Communities of 20 February 1979. The derived "Cassis-de-Dijon principle" states in general that all products that are in a EU Member State may be sold in all other Member States regardless of the possibly different provisions for such a product. According to the judgment, a Member State may restrict the free movement of goods in the EU only for very specific reasons which are in the public interest (fiscal control, public health protection, fair trade protection and consumer protection).
The verdict was based on the fact that the German trade group Rewe from the Burgundian Dijon the currant liqueur Cassis imported and sold in their stores. Thereupon forbade the federal monopoly administration for spirits the further import and sale of goods from France, as the supposed liqueur with his alcohol content from 16% to 22% by volume did not correspond to the alcohol content of 25% vol for liquors required by the German Spirits Monopoly Law. Rewe's claim was complied with in the judgment on the grounds that the prohibition was "incompatible with the free movement of goods by European standards". This judgment subsequently had a prejudicial effect. See also below wine law,
