Rewe-Zentral v Bundesmonopolverwaltung für Branntwein (1979) Case C-120/78, popularly known as Cassis de Dijon after its subject matter, 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. In the same ruling, the Court established the so-called rule of reason, allowing non-discriminatory restrictive measures to be justified on grounds other than those listed in article 36 TFEU.
