Question juridique clé
Whether the remand order was an appealable interim decision under Art. 93 BGG
Solution extraite
The order was an interim decision, but the appellant failed to show an irreparable legal disadvantage or a significant saving of time/cost; the appeal was therefore inadmissible.
Motifs extraits
Any disadvantage from allowing the respondent to supplement deficient allegations could still be cured later by relying on the previously established procedural record. The appellant also did not substantiate a significant evidentiary burden for Art. 93(1)(b) BGG.
