Question juridique clé
Whether Art. 38 EIMP or Art. 14 CEExtr required prior warning about the 45-day grace period and its consequences.
Solution extraite
The extradited person had to be instructed about the consequences of remaining in Switzerland; the warning requirement under Art. 38 EIMP applied as a general principle and was not displaced here by Art. 14 CEExtr.
Motifs extraits
The court held that international cooperation had ended with extradition and return of the person to Swiss custody. The later enforcement decision was no longer an act of mutual assistance, so the domestic rule on specialty and warning applied. The person had not been informed of the legal consequences of staying or returning after release.
