Question juridique clé
Whether the appeal met the reasoning requirements of Art. 42 BGG.
Solution extraite
No. The filing did not engage in a sufficient, case-specific way with the decisive reasons of the cantonal judgment.
Motifs extraits
The appellant only disputed one factual point about past detention duration, but did not show how that alleged error could affect the legality of the 2009 detention extension; thus the submission lacked the required substantiated legal reasoning.
