Question juridique clé
Whether the appeal could be entertained despite a request only for annulment and remand
Solution extraite
The appeal was in principle admissible because, on the hearing-right complaint, the Federal Tribunal could not decide the merits itself and would have to remand.
Motifs extraits
Although the appeal is generally a reformative remedy, an exception applies where the alleged violation of the right to be heard would necessarily require remittal for further evidence.
