Key legal question
Whether the cantonal court violated the right to be heard by not addressing asylum-related arguments and alleged nullity of the federal asylum decision.
Extracted holding
No violation was shown; asylum arguments were irrelevant in detention review unless a grave defect causing nullity of the removal decision was specifically demonstrated.
Extracted reasoning
The duty to give reasons allows courts to address only pertinent arguments. In detention proceedings, the asylum procedure cannot be challenged except for a serious defect leading to nullity, which the appellant failed to identify or substantiate.
