Questão jurídica principal
Whether the cantonal court’s non-entry for late payment of the advance costs was excessive formalism or violated Article 29(1) BV.
Decisão extraída
No. The taxpayers were sufficiently informed about the amount, deadline, and consequences; the court was not required to warn additionally about the cantonal holiday suspension or to grant a grace period.
Fundamentação extraída
The advance-payment request clearly stated the amount, deadline, and non-entry consequence. The taxpayers had to verify the applicable cantonal rules themselves, especially because the tax-law appeal instructions expressly indicated that court vacations did not apply in tax matters. In any event, the payment was late even under the most favorable view of the decisive date.
