Kernrechtsfrage
Whether refusal to take evidence violated the right to be heard
Extrahierter Entscheid
The refusal did not violate the right to be heard because the requested evidence concerned facts that were irrelevant, admitted, or insufficiently specified.
Extrahierte Begründung
The court held that the decisive question was only whether the bank was entitled to release the joint-account assets to the surviving co-holder; the broader history of the account and vague evidence offers were not shown to concern relevant facts.
