Kernrechtsfrage
Whether the federal appeal was sufficiently reasoned under Art. 42 LTF
Extrahierter Entscheid
No. The appellant did not contest the cantonal court's lateness-based inadmissibility reasoning, so the appeal lacked the required reasoning.
Extrahierte Begründung
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.
