Key legal question
Whether the refusal to admit the producer and receive his cheese for affining was an unlawful restraint of competition
Extracted holding
The refusal was abusive and unlawful because the Cooperative held a dominant position and had no objective justification.
Extracted reasoning
The relevant market was the market for cheese marketed under the protected Etivaz appellation. The Cooperative was the sole effective affiner and thus dominant. It could in principle accommodate the producer's output, and the refusal was not justified by capacity constraints or by any other objective reason.
