Questione giuridica chiave
Whether the appellant could be barred from suing because of its own allegedly misleading advertising (unclean hands).
Decisione estratta
No. A competitor's own unfair conduct does not generally deprive it of standing to challenge another competitor's unfair competition.
Motivazione estratta
Swiss unfair competition law protects competitors, consumers, and the public. Allowing an unclean-hands objection would let unfair conduct escape review and undermine the statute.
