Kernrechtsfrage
Whether declaring the cantonal appeal inadmissible for late payment of the second installment of the fee advance constituted excessive formalism under Article 29(1) of the Constitution.
Extrahierter Entscheid
No. Where the appellant is duly warned of the amount, deadline, and consequence of non-payment, dismissing the appeal for untimely payment of a required fee advance does not amount to excessive formalism.
Extrahierte Begründung
The appellant had been expressly warned that failure to pay the installments on time would lead to inadmissibility. The applicable cantonal rule left discretion, but settled case law allows such a sanction when the warning requirement is met. The claimed illness and spouse's absence were unsubstantiated and, even if true, were not extraordinary enough to prevent a request for extension.
