Questione giuridica chiave
Whether the cantonal court was competent to hear the complaint under Art. 30(1) Cst.
Decisione estratta
Yes. The challenge to access a closed criminal file belongs to administrative contentious jurisdiction, and an erroneous indication of remedies does not create competence where the law provides none.
Motivazione estratta
The transmission to the public-law chamber did not prejudice the parties and was consistent with procedural economy; the court competent by law could validly decide the matter.
