Kernrechtsfrage
Whether the BSV's appeal against the remand decision was admissible under Art. 90 or Art. 93 BGG.
Extrahierter Entscheid
The remand decision was not a final decision; the requirements for an immediately appealable interim decision were also not shown, so the appeal was inadmissible.
Extrahierte Begründung
The remand left essential questions open, in particular whether the insured person might opt for a lump-sum payment under the social security agreement. The BSV did not substantiate any irreparable harm or significant saving of time/costs.
