Questão jurídica principal
Whether the federal appeal against the cantonal detention order was admissible
Decisão extraída
The appeal was admissible because the challenged decision was issued by the canton’s last instance, was filed in time, and the detainee had standing to appeal.
Fundamentação extraída
The Court held that a public-law appeal lies against last cantonal decisions in coercive-measures matters even if the appellant did not expressly name that remedy; the filing was timely and the grievance sufficiently clear.
