Question juridique clé
Whether the Federal Office had standing to appeal the remand judgment as a final decision
Solution extraite
The remand judgment was not a final decision because it left substantive issues open, notably whether an abfindung instead of a pension might be due.
Motifs extraits
The lower court decided only the applicable law, not all decisive questions. Since the insured may have opted for a lump-sum refund under the bilateral agreement, the remand required more than mere implementation.
