Case 43/75, Defrenne v Sabena [1976] ECR 455

D worked as a flight attendant for the airline Sabena. The airline paid her less than her male colleagues who did the same work. The ECJ held that Article 119 of the Treaty of the European Community was of such a character as to have horizontal direct effect, and therefore enforceable not merely between individuals and the government, but also between private parties. Article 157 TFEU (119 TEEC, 141 TEC) was invoked which stated "Each Member State shall ensure that the principle of equal pay for male and female workers for equal work or work of equal value is applied".
