Question juridique clé
Whether the federal appeal was sufficiently reasoned under Art. 42 LTF
Solution extraite
No. The appellant did not contest the cantonal court's lateness-based inadmissibility reasoning, so the appeal lacked the required reasoning.
Motifs extraits
Under Art. 42(1)-(2) LTF, the appellant must explain briefly how the challenged decision violates the law. Because the submission did not address the decisive ground of lateness, it failed to meet that requirement and had to be refused under Art. 108(1)(b) LTF.
