Kernrechtsfrage
Whether the cantonal court's finding of the parties' true and common intention could be reviewed on reform appeal
Extrahierter Entscheid
The finding of the parties' actual intent was a factual determination and could not be challenged in reform proceedings.
Extrahierte Begründung
Subjective interpretation under Art. 18 CO depends on establishing the real common intention. Once the cantonal court is convinced of that intent, the Federal Court cannot revisit it on reform appeal.
