Key legal question
Whether the public appeal against the detention-extension order was admissible despite the requested relief seeking immediate release.
Extracted holding
A detainee may request the Federal Tribunal to order release or to instruct the cantonal authority to do so; the conclusions were admissible.
Extracted reasoning
In detention matters, a public-law appeal is not limited to annulment; case law allows a request for release. Some criticism directed at earlier measures was irrelevant to the challenged order and therefore inadmissible.
