Kernrechtsfrage
Whether the appellate court president could order preventive detention as an interim measure after the coercive measures court refused detention.
Extrahierter Entscheid
Yes. The appellate instance may take urgent provisional measures, including preventive detention, while the prosecutor's cantonal appeal against a release order is pending.
Extrahierte Begründung
Articles 222, 388 and 393 CPC allow cantonal appeal against the release decision; once seized, the appellate authority has procedural direction under Article 388 CPC, and Article 387 CPC expressly yields to contrary CPC rules and procedural-direction decisions. Article 388 letter b CPC specifically authorizes provisional detention measures.
