Key legal question
Whether the appeal was admissible against the cantonal remand order.
Extracted holding
The remand order was an independently appealable interim decision, but the appellant failed to show a non-reparable prejudice or significant procedural savings under Art. 93 BGG.
Extracted reasoning
The challenged decision only sent the matter back for further fact-finding; the appellant did not substantiate the admissibility requirements and could later challenge the rent-cost issue together with the final decision.
