Kernrechtsfrage
Whether the complaint could still challenge issues beyond the remand scope and the earlier ruling's binding effect.
Extrahierter Entscheid
Only the remaining issue after remand could be reviewed; broader challenges were inadmissible.
Extrahierte Begründung
The remand decision bound lower courts and the Federal Supreme Court in the subsequent proceedings; matters already decided or that should have been challenged earlier could no longer be reopened.
