Question juridique clé
Whether the cantonal remand on the invalidity pension could be appealed immediately.
Solution extraite
The remand decision was an interlocutory decision not separately challengeable because no Art. 93 BGG ground was shown.
Motifs extraits
A remand for further fact-finding does not end the proceedings and is only appealable under Art. 93 BGG if its prerequisites are met; this was neither alleged nor obvious.
