Key legal question
Whether the administrative appeal against the detention order was sufficiently reasoned and could be treated as a valid challenge to detention
Extracted holding
The filing was accepted as a Verwaltungsgerichtsbeschwerde because it showed that the detainee objected to the detention itself, even though it was in lay form.
Extracted reasoning
For lay complaints in detention matters, strict formal requirements are relaxed; the court nonetheless reviews only the lawfulness of the detention measure, not broader removal-enforcement issues.
