Question juridique clé
Whether the appeal was admissible against the cantonal remand decision on the pension issue.
Solution extraite
The remand decision was an appealable interlocutory decision only if Art. 93(1) BGG was met; these conditions were not satisfied.
Motifs extraits
The remand caused no irreparable harm and imposed no materially binding instruction forcing an unlawful new decision; it merely required further clarification and a new assessment.
