Question juridique clé
Whether the federal appeal was admissible against the cantonal remand judgment.
Solution extraite
The judgment was a challengeable incidental decision, but the appellant failed to contest all independent alternative grounds supporting the remand; the appeal was therefore inadmissible.
Motifs extraits
Under Art. 42(2) LTF, all sufficient alternative reasons must be attacked. The cantonal judgment rested on two independent income-comparison calculations establishing sufficient invalidity for retraining. Only one was challenged.
