Questione giuridica chiave
Whether refusing appellate evidence violated the right to be heard
Decisione estratta
The refusal did not violate the right to be heard insofar as the requested evidence concerned a right to proof under federal law that had to be raised in the ordinary appeal on the merits, not in the subsidiary public-law appeal.
Motivazione estratta
The alleged violation of the right to proof fell within Art. 8 CC and was therefore not reviewable in this subsidiary remedy; the constitutional complaint could not be used to bypass the ordinary federal appeal.
