Kernrechtsfrage
Whether the public-law appeal against the cantonal remand decision was admissible.
Extrahierter Entscheid
The appeal was at least doubtful as to admissibility because the remand decision may be incidental and may not cause irreparable legal harm, but the court left the point open.
Extrahierte Begründung
A remand order is incidental if it does not finally end the dispute; irreparable harm must be legal, not merely factual. The court considered that X.________ SA might still obtain the award.
