Kernrechtsfrage
Whether the appeal to the Federal Supreme Court was admissible against the cantonal remand order.
Extrahierter Entscheid
The remand decision was an interlocutory decision, and the appellant did not show any admissibility ground under Art. 92 or 93 BGG; the appeal could therefore not be entered upon.
Extrahierte Begründung
Interlocutory decisions are only exceptionally appealable. The brief did not address the special requirements, and the remand caused neither irreparable harm nor saved extensive evidence proceedings because the disputed claims had not yet been examined.
