Case C‑446/07Alberto Severi, in his own name and representing Cavazzuti e figli SpA, now known as Grandi Salumifici Italiani SpAv Regione Emilia-Romagna. From the decision: " Articles 3(1) and 13(3) ... must be interpreted as meaning that the designation of a foodstuff containing geographical references, which is not registered as a protected designation of origin or a protected geographical indication, may legitimately be used, on condition that the labelling of the product so named does not mislead the average reasonably well informed, observant and circumspect consumer. For the purpose of assessing whether that is the case, national courts may have regard to the length of time during which the name has been used. By contrast, any good faith on the part of the manufacturer or retailer is irrelevant in that regard"
