Kernrechtsfrage
Whether the appeal against the interlocutory ruling refusing reform and additional expertise was admissible.
Extrahierter Entscheid
The appeal was inadmissible because the challenged ruling was an interlocutory decision on reform, not a final judgment or a reform introducing new or increased claims.
Extrahierte Begründung
Under Art. 145 para. 3 CPC, interlocutory rulings can normally be challenged only together with the final judgment. Immediate review is possible only when reform introduces new or enlarged claims; here the request merely sought a supplementary expert report.
