Kernrechtsfrage
Whether the federal appeal against the cantonal remand/interim decision was admissible under Art. 93 BGG.
Extrahierter Entscheid
The decision was appealable because allowing the appeal could immediately end the case on the main claim and would avoid extensive evidence proceedings.
Extrahierte Begründung
Although the cantonal ruling was an interim decision, the requested reversal would have led to a final decision on the partial claim, and the record showed that the remaining evidentiary proceedings would be lengthy and costly.
