Key legal question
Whether the cantonal court could deny party compensation against the canton under Art. 107(2) ZPO
Extracted holding
The refusal was not arbitrary; the court could treat the parties' own appellate costs as unnecessary process costs and leave them to each party.
Extracted reasoning
Art. 107(2) ZPO concerns court costs; the prior filing was only needed to correct an obvious clerical/procedural error, so the parties' appellate proceedings were unnecessary within the meaning of Art. 108 ZPO.
