Questão jurídica principal
Whether the federal appeal was admissible and what scope of review applied
Decisão extraída
The appeal was admissible in principle, but review was limited to federal law and the appellants could not rely on new facts or cantonal-law arguments.
Fundamentação extraída
The dispute met the value threshold for unfair-competition cases and was timely; however, the Federal Supreme Court could only review federal-law issues and had to rely on the cantonally established facts.
