Questione giuridica chiave
Whether the appeal was admissible, in particular whether the appellant had a legal interest under Art. 76(1)(b) LTF.
Decisione estratta
The appellant lacked a legal interest because the cantonal ruling had no binding legal effect and did not determine any enforceable right or duty between the parties.
Motivazione estratta
The parties had no contractual or extra-contractual legal relationship. The cantonal decision was only an abstract legal opinion on a theoretical question, incapable of binding non-parties and without dispositive effect even between the parties.
