Questione giuridica chiave
Whether the cantonal court arbitrarily computed the extended deadline for paying the court-fee advance by running it from the end of the previous deadline.
Decisione estratta
The cantonal court's method was not arbitrary; the extended deadline formed a continuous whole with the initial deadline and therefore ran uninterrupted from the expiry of the original term.
Motivazione estratta
The text of the cantonal procedural code did not clearly settle the calculation after prolongation. Relying on the parallel federal rules, prior federal case law, and majority doctrine, the cantonal practice was defensible, even if another interpretation was possible.
