Kernrechtsfrage
Whether the appeal against the compulsory detention was admissible only as to federal law violations and within the limits of the established facts
Extrahierter Entscheid
Only federal-law complaints were cognizable; constitutional and ECHR arguments could not be raised directly by appeal, and the court was bound by the factual findings below.
Extrahierte Begründung
The Federal Supreme Court emphasized the limits of the appeal under the OG and refused to consider attacks on facts, new allegations, or claims unrelated to the detention order itself.
