Kernrechtsfrage
Whether the earlier Gersau judgment created res judicata on the claimant's active standing in the commission action
Extrahierter Entscheid
No. The earlier decision determined active standing only as a preliminary question in a document-disclosure claim, not as the main issue in the commission dispute.
Extrahierte Begründung
Material res judicata under Swiss law extends only to the dispositive part and, objectively, only to the claim actually decided. Findings and reasons are not binding in a different dispute; a preliminary issue is binding only if it was previously decided as the main issue.
