Whether the appeal against the interlocutory ruling refusing reform and additional expertise was admissible.
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.
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.
