Question juridique clé
Whether the federal appeal against the cantonal remand decision was admissible under Art. 93 para. 1 lit. b LTF.
Solution extraite
The remand decision was incidentally appealable in principle, but the appellant failed to show that immediate admission would avoid a long and costly evidentiary procedure.
Motifs extraits
Further instruction was limited and could potentially be reduced to hearing one witness; the appellant did not substantiate the prerequisites for an immediate appeal.
