Question juridique clé
Whether the remand order was immediately appealable under Art. 93 LTF
Solution extraite
The remand order did not make an immediate final decision possible and the appellant did not show that the further evidence would be unusually long and costly.
Motifs extraits
A remand for additional instruction is not enough by itself; the appellant must demonstrate a probative procedure departing significantly from ordinary litigation. The expected evidence here—party statements, document production, and possibly limited expert review—was not shown to be complex enough.
