Questione giuridica chiave
Whether the Federal Court had jurisdiction to review the cantonal ruling on an alleged gift-like discharge of the debt.
Decisione estratta
No. The alleged waiver by gift was governed by cantonal law under Art. 141 OR, so the cantonal court's assessment was not reviewable by the Federal Court.
Motivazione estratta
The only serious objection was that the father had forgiven the remaining price as a gift. Since Art. 141 OR leaves such gratuitous remission to cantonal law, the question whether donor intent existed was a matter of cantonal, not federal, law.
