Case C-443/98 Unilever Italia v. Central Food (judgment of 26 September 2000) concerned a dispute between two private undertakings over a contract for the supply of olive oil. Central Food refused to accept delivery because the oil did not comply with labelling requirements imposed by recent Italian legislation. Unilever claimed that the Italian rules were themselves governed by the provisions of Directive 83/189 [1983] O.J. L109/8. Under Article 8 of the Directive, member States must notify draft technical regulations to the Commission. In Case C-194/94 CIA Security [1996] ECR I-2201, the ECJ held that breach of this obligation rendered the relevant technical regulations inapplicable, and thus unenforceable before the national courts, even in a dispute between two private parties based on domestic rules prohibiting unfair trading. Italy had notified its draft labelling rules to the Commission as required by Article 8, but nevertheless continued to enact those proposals into law contrary to the standstill obligations contained in Article 9. Unilever argued that the principle in CIA Security should extend also to Article 9, obliging Central Food to accept delivery in accordance with its contractual duties.
