Kernrechtsfrage
Whether the appeal against the cantonal remand decision was admissible under Art. 93 BGG.
Extrahierter Entscheid
The decision was a separately appealable interlocutory decision, but neither an irreparable disadvantage nor the conditions for immediate final review were shown.
Extrahierte Begründung
The appellant did not substantiate any non-reparable harm, and a possible immediate final decision would not save significant time or costs in a complex evidentiary procedure. A later appeal against the final decision remained available.
