Key legal question
Whether the appeal against the detention prolongation was sufficiently motivated and filed in an admissible language.
Extracted holding
The appeal did not meet the motivation requirements of Art. 42 LTF, and the later Romanian submissions could not cure that defect.
Extracted reasoning
The appellant merely raised general objections and did not explain why the detention decision violated federal law. Although he was informed that he could supplement the appeal in an official language within the statutory time limit, his additional submissions were also insufficiently reasoned.
