Rewe-Zentral AG v Bundesmonopolverwaltung für Branntwein (1979) Case 120/78, popularly known as the Cassis de Dijon case, is an EU law decision of the European Court of Justice. The Court held that a regulation applying to both imported and to domestic goods (an "indistinctly applicable measure") that produces an effect equivalent to a quantitative import restriction is an unlawful restriction on the free movement of goods. The case is a seminal judicial interpretation of article 34 of the Treaty on the Functioning of the European Union.
