2 Case 11/76 Netherlands v Commission [1979] ECR 245, Case 265/78 H. Ferwerda BVv Produktschap voor Vee en Vlees [1980] ECR 617 and Joined Cases 119 and 126/79 Lippische Hauptgenossenschaft eG and Another v Bundesanstalt für landwirtschaftliche Marktordnung [1980] ECR 1863. I also discussed the judgments in Case 118/76 Balkan Import-Export GmbH v Hauptzollamt Berlin-Packhof [1977] ECR 1177 and Case 130/79 Express Dairy Foods Limitedv Intervention Board for Agricultural Produce [1980] ECR 1887 which are also material to the recovery of wrongly-paid amounts, as well as other judgments indirectly relevant to this issue. Paragraph 13 of the decision in Case 130/79 cited above and paragraph 26 of the decision in Case 61/79 Amministrazione delle Finanze dello Stato v Denkavit Italiana srl [1980] ECR 1205 at p. 1226 are particularly material to the question whether it is relevant that the wrongly-paid amounts are passed on.
