Kernrechtsfrage
Whether the appeal against the remand order was admissible despite its interlocutory nature.
Extrahierter Entscheid
The remand order could be appealed because it bound the IV office on disability assessment and caused irreparable prejudice.
Extrahierte Begründung
The appeal could not lead directly to a final decision, but the office was bound by the lower court's instructions on invalidity assessment, which satisfied the irreparable-damage requirement under Art. 93 BGG.
