Questione giuridica chiave
Whether the public law appeal was admissible despite the availability of a complaint under Art. 19 para. 1 LP
Decisione estratta
The public law appeal was inadmissible because the same grievance could be fully raised by the LP complaint.
Motivazione estratta
The challenged ruling was open to review under Art. 19 para. 1 LP; since arbitrariness under Art. 9 Cst. could be examined through that route, the subsidiary public law appeal was barred by Art. 84 para. 2 OJ.
