Kernrechtsfrage
Whether the appellant's own appeal against the remittal decision was admissible under Art. 93 BGG
Extrahierter Entscheid
The remittal decision did not cause irreparable harm and did not justify immediate review; the appeal was inadmissible.
Extrahierte Begründung
A remittal for further clarification usually only prolongs proceedings. No material instructions constrained the lower authority's discretion in a way that would force an unlawful new decision, and no exception under Art. 93 BGG was shown.
