Question juridique clé
Whether the appeal against the cantonal remand order was admissible under Art. 93 BGG
Solution extraite
The remand order was an interlocutory decision and the conditions for an immediate appeal were not met.
Motifs extraits
The order only required additional expert evidence and bound the IV office to no substantive findings, so no irreparable prejudice existed. Nor was it shown that immediate review would save significant time or costs.
