Key legal question
Whether the appeal against the detention-extension judgment was sufficiently reasoned under Art. 42 BGG.
Extracted holding
The appeal did not engage with the decisive reasoning of the cantonal judgment and therefore lacked the required substantiation.
Extracted reasoning
The appellant merely repeated earlier objections about nationality, health, and UN working group comments without addressing the detailed findings on removability, conduct, and lack of grounds for release; the complaint therefore failed to show legal error as required by Art. 42 para. 2 BGG.
