Questione giuridica chiave
Whether the cantonal court committed excessive formalism or arbitrariness by declaring the cantonal appeal inadmissible for non-payment of the advance of costs.
Decisione estratta
No. The appellant had been properly warned of the amount, deadline and consequences, and failure to pay justified inadmissibility.
Motivazione estratta
The advance-of-costs requirement and warning complied with cantonal procedural law; non-payment within the set time did not amount to excessive formalism or arbitrary application of the law.
