Questione giuridica chiave
Whether the cantonal order denying free legal aid and requiring a cost advance was appealable by public law appeal.
Decisione estratta
The order was an interlocutory decision capable of causing irreparable harm, so the public law appeal was admissible; the subsidiary constitutional complaint had no independent significance.
Motivazione estratta
A refusal of legal aid combined with a cost advance can create irreparable disadvantage under Art. 93 BGG, and constitutional grievances could be raised in the ordinary appeal.
