Kernrechtsfrage
Whether the appeal against the extension of deportation detention was sufficiently reasoned and admissible.
Extrahierter Entscheid
The appeal was inadmissible because it only attacked the final, unchallenged residence-permit refusal and did not address the legality of the detention extension itself.
Extrahierte Begründung
Under Art. 42 BGG, the appeal must target the subject of the challenged decision and explain concretely how it violates the law. The appellant failed to engage with the detention-extension reasoning; the underlying permit refusal was final and could not be relitigated.
