Kernrechtsfrage
Whether refusing to hear witness B. violated the appellant's right to be heard under Art. 29(2) Cst.
Extrahierter Entscheid
No. The proposed testimony was not relevant, because it would not reliably prove tax exemption of the recipient or a legally cognizable fiduciary relationship.
Extrahierte Begründung
The tax authority's records showed the recipient association was not tax-exempt; a mere intention to pass collected funds on to a third party does not establish fiduciary ownership for tax purposes.
