Key legal question
Whether the appeal against the security detention decision was admissible and reviewable under federal criminal procedure rules
Extracted holding
The appeal was admissible in principle, and the Federal Supreme Court reviewed the detention decision with full cognition on the federal-law requirements for restricting fundamental rights.
Extracted reasoning
Security detention is a criminal coercive measure that definitively affects liberty interests and is not merely an interim measure under Art. 98 BGG; therefore the ordinary appellate framework applies.
