Kernrechtsfrage
Whether the federal appeal met the substantiation requirements of Art. 42 LTF.
Extrahierter Entscheid
No. The appellant argued only on the merits and did not explain why the cantonal appeal was admissible in form.
Extrahierte Begründung
Under Art. 42 paras. 1-2 LTF, the appeal must briefly show how the challenged decision violates the law. Because the attacked decision primarily found the cantonal appeal inadmissible for lack of motivated requests, the federal appeal had to address that procedural ground. It did not, so inadmissibility followed under Art. 108 para. 1 lit. b LTF.
