Question juridique clé
Whether the appeal against the cantonal remand order was admissible under Art. 93 BGG.
Solution extraite
The remand order was a separately appealable interim decision, but neither a non-reparable prejudice nor a justification based on immediate final adjudication and evidentiary economy was shown.
Motifs extraits
A remand for further clarification usually causes no irreparable harm, and the appellant did not demonstrate that immediate review would end the case and avoid extensive evidence taking. The challenged ruling could be reviewed later with an appeal against the final decision.
