Question juridique clé
Whether the federal criminal appeal was admissible against the cantonal order declaring the visitation complaint inadmissible.
Solution extraite
The federal appeal was admissible because the challenged order related to a criminal-procedure matter and was appealable either as a final decision or as an incident causing irreparable harm.
Motifs extraits
The dispute arose from criminal procedure and detention; therefore it fell within Art. 78 LTF, and the appellant had standing. The court also accepted admissibility under the final-decision or incidental-decision routes of the LTF.
