Kernrechtsfrage
Whether the federal complaint against the non-entry decision was admissible.
Extrahierter Entscheid
The complaint was inadmissible because it did not substantiate any violation of federal law and only argued the merits of the case, which cannot be reviewed against a non-entry decision.
Extrahierte Begründung
The appellant admitted he had probably erred in the date. He did not claim that the cantonal court violated Art. 95 BGG by declining to hear the late appeal notice. The filing contained only substantive arguments, which are impermissible in a complaint directed against a non-entry decision; therefore summary non-entry under Art. 108 BGG was justified.
