Key legal question
Whether the appeal against the extension of enforcement detention was admissible and well-founded.
Extracted holding
The appeal was rejected insofar as it was admissible; the challenged extension remained in force.
Extracted reasoning
The complaint was manifestly unfounded and could be decided summarily under Art. 109 BGG. The appellant still refused to cooperate with the authorities, so the detention remained proportionate and could continue to serve its coercive purpose.
