Questione giuridica chiave
Whether the dispute concerns public law and is reviewable under public-law appeal.
Decisione estratta
The matter is governed by public law because SBB's management of station advertising space is an exercise of public-law administration of public property.
Motivazione estratta
Station areas and advertising sites are tied to SBB's public-service tasks; the concrete measure regulates use of public property and not a private contractual relationship.
