Questione giuridica chiave
Whether the constitutional complaint could challenge the cantonal court's refusal to take evidence because of alleged lack of substantiation.
Decisione estratta
The complaint was inadmissible because the question of sufficient substantiation is a matter of federal law and had to be raised by appeal, not by constitutional complaint.
Motivazione estratta
The court distinguished between alleged arbitrary evidentiary assessment and the prior question whether the factual allegations were sufficiently pleaded to require evidence. That pleading issue is governed by federal law and therefore outside the scope of the constitutional complaint.
