Kernrechtsfrage
Whether the four-month security detention extension violated Art. 227 al. 7 CPP because no exceptional case was expressly addressed.
Extrahierter Entscheid
The cantonal court implicitly accepted an exceptional case; the extension was permissible because the detention ground, especially flight risk, would still persist after three months.
Extrahierte Begründung
The Federal Court held that confirmation of the lower order allows an implicit finding of an exceptional case. Given the increased exposure to a higher sentence and the continued flight risk, it was foreseeable that the detention ground would still exist on 2 December 2011.
