Kernrechtsfrage
Whether the constitutional complaint was barred by the subsidiarity rule because the dispute could have been brought by federal appeal.
Extrahierter Entscheid
The complaint was admissible for the challenged third-party disclosure order because Art. 697d(2) OR regulates a procedural duty of third parties, not a civil-law claim between the parties to the special audit.
Extrahierte Begründung
The Court distinguished the special-audit entitlement of shareholders against the company from the separate question whether third parties must give information or produce documents. The latter is a federal procedural/evidentiary rule and not a civil dispute within the meaning of the appeal provisions.
