Question juridique clé
Whether the federal appeal against the cantonal remand order was admissible under Art. 93 BGG.
Solution extraite
The remand order was an interim decision and did not cause a non-reparable legal disadvantage; the appeal was therefore inadmissible.
Motifs extraits
A remand for further fact-finding normally only prolongs the proceedings. The appellant did not show any specific irreparable legal disadvantage, and no exception under Art. 93(1)(b) BGG applied.
