Question juridique clé
Whether the appeal against the detention order met the admissibility requirements of Art. 42 BGG.
Solution extraite
The filing did not sufficiently show how the challenged decision violated federal law within the scope of the proceedings, so the Court could not enter into it.
Motifs extraits
The appellant mainly complained about the translator's alleged insult and did not present a reviewable objection against the detention decision itself. The alleged translation issue was not part of the appealable subject matter.
