Question juridique clé
Whether the appeal in public law matters against the non-contested remand decision was admissible.
Solution extraite
The appeal was inadmissible because the decision on the remand was not challenged on the merits; the issue of party compensation can be reviewed later with an appeal against the final decision, and no irreparable harm existed.
Motifs extraits
Under established case law, a material challenge to a remand decision is required for immediate review. The compensation issue remains open to later review under Art. 93(3) BGG, and the appellant retained access to the Federal Supreme Court after the new administrative decision if needed.
