Question juridique clé
Whether the federal complaint met the minimum substantiation requirements of Art. 42 BGG.
Solution extraite
No. The appellants addressed mainly the merits and did not show, with respect to the only relevant issue, that the cantonal findings on the expiry of the appeal deadline were manifestly incorrect or unlawful.
Motifs extraits
A complaint must state requests and reasons in condensed form; because the appellants failed to engage with the decisive procedural question and did not challenge the factual findings under the applicable standard, the filing lacked a case-specific legal argument.
