Question juridique clé
Whether the federal appeal against the cantonal remand order was admissible
Solution extraite
The remand order created a legally relevant disadvantage because the insurer would otherwise be bound to grant higher pension benefits before the repayment claim could be enforced.
Motifs extraits
A remand decision is usually an interlocutory decision, but here the insurer was bound by the lower court's finding of a relevant worsening and would have to issue a new decision it could not itself challenge; that satisfies Art. 93(1)(a) BGG.
