Questione giuridica chiave
Whether the State was properly represented and the appeal was admissible, including standing and lack of a separate declaratory interest.
Decisione estratta
The appeal was admissible in principle, but the request for a standalone declaration of no contribution liability was inadmissible.
Motivazione estratta
The Regierungsrat could retroactively authorize the appeal; the appellant was specially affected. A declaratory request was unnecessary because a constitutive ruling on the contribution duty would already resolve the matter.
