Kernrechtsfrage
Whether the Bundesgericht could examine complaints unrelated to the detention review, including the entry ban
Extrahierter Entscheid
Only the legality of the detention order was reviewable; complaints not directed against the detention decision were not entertained, including the challenge to the entry ban.
Extrahierte Begründung
The cantonal judge decided only on the lawfulness and appropriateness of the detention order; on federal review only the legality of detention was at issue.
