Questione giuridica chiave
Whether the appeal of public law was admissible to challenge the cantonal tenancy court's subject-matter competence.
Decisione estratta
Yes. The challenged decision was final and no other federal remedy was available for a direct constitutional complaint on this point.
Motivazione estratta
Subject-matter competence under cantonal law could not be reviewed by ordinary reform appeal; therefore public law appeal was the proper remedy.
