Key legal question
Whether the appeal against the remand decision was admissible under Art. 93 BGG.
Extracted holding
The remand decision was an interim decision and no irreparable legal harm was shown; the appellants also failed to demonstrate that immediate acceptance would finally resolve the case and save substantial time or costs.
Extracted reasoning
A self-standing remand order is an interim decision. It is only appealable if it can cause irreparable legal harm or if Art. 93(1)(b) BGG is met. The appellants could later challenge the remand decision together with the final judgment, and they did not substantiate the conditions of Art. 93(1)(b) BGG.
