Key legal question
Whether the cantonal appeal inadmissibility violated access to court, the right to be heard, proportionality, good faith, and protection against excessive formalism.
Extracted holding
No. The three-copy requirement was a valid formal rule, the appellant was given a reasonable cure period, and the sanction of inadmissibility was proportionate.
Extracted reasoning
Formal filing requirements do not conflict with access to justice. The rule served administrative efficiency, equality, and legal certainty. The authority expressly warned of inadmissibility and gave a reasonable grace period; the remaining defect was attributable to the appellant and his lawyer.
