Key legal question
Whether the appeal against the cantonal decision on detention pending removal is admissible and what is its scope.
Extracted holding
The federal appeal is admissible as an appeal in public law, but the request to renew the residence permit is inadmissible because it lies outside the dispute, which concerns only the detention pending removal.
Extracted reasoning
The court treated the filing according to its substance despite the unclear label and limited review to the subject of the challenged decision.
