Kernrechtsfrage
Whether refusing appellate evidence violated the right to be heard
Extrahierter Entscheid
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.
Extrahierte Begründung
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.
