Whether the cantonal recourse was admissible against the costs decision rendered in provisional measures.
The recourse was not admissible, because a costs challenge under Art. 94 al. 1 CPC is available only when the merits decision itself is subject to a further remedy other than nullity; provisional-measures decisions are not subject to a reform appeal.
The court applied its settled case law that costs are not separately recourseable when the underlying decision cannot be attacked by reform appeal. Since provisional measures can only be challenged by appeal to the rental court, the ordinary recourse route is closed.
