Key legal question
Whether the public law appeal was admissible despite challenging only the lower courts' refusal to consider the case on the merits.
Extracted holding
The appeal was inadmissible because it did not contest the formal ground of lateness in a legally sufficient manner and instead argued the merits.
Extracted reasoning
When the last cantonal authority rejects a complaint for formal reasons without examining the merits, the appellant must explain why the formal precondition assessment was arbitrary. The appellant failed to do so.
