Question juridique clé
Whether the federal criminal appeal against the cantonal president's urgent authorization was admissible.
Solution extraite
The appeal was admissible because the decision was based on cantonal criminal procedure and could affect evidence preservation; any irreparable harm requirement was sufficiently shown at the admissibility stage.
Motifs extraits
The order was an incidental measure under cantonal procedure concerning possible evidentiary alteration, so federal criminal appeal review was open.
