Kernrechtsfrage
Whether the appeal against the remand judgment was admissible under Art. 93 BGG
Extrahierter Entscheid
The remand decision was an appealable interim decision because it could cause irreparable legal harm if binding legal instructions became final.
Extrahierte Begründung
A remand decision is only challengeable if the lower authority's discretion is materially constrained by binding legal reasoning that cannot later be corrected; that condition was met here.
