Question juridique clé
Whether the cantonal court could award party costs after issuing a non-entry decision for lack of territorial jurisdiction.
Solution extraite
Yes. Under the causation principle, a costs award against the authority was permissible even though the court did not decide the merits.
Motifs extraits
The authority caused additional procedural work by filing the matter with the wrong court. The fact that no party prevailed on the merits did not bar compensation, and any later costs award by the competent Tessin court would exclude already compensated work.
