Question juridique clé
Whether the federal criminal appeal was admissible against the cantonal remand order
Solution extraite
The challenged decision was incidental and did not meet either prerequisite for an immediate appeal under Art. 93 LTF.
Motifs extraits
The remand order did not end the criminal case and caused no irreparable legal harm; mere prolongation of the proceedings or added costs is insufficient. Nor was an immediate final decision likely to avoid a long and costly evidentiary procedure.
