Questione giuridica chiave
Whether the constitutional complaint was admissible despite non-payment of the court advance within the non-extendable grace period.
Decisione estratta
No. The appellant failed to pay the CHF 700 advance in time or prove timely debit; the complaint was therefore not entered upon.
Motivazione estratta
After a warning under Art. 62(3) BGG, the appellant neither paid cash nor at a post office nor proved timely debit by bank/post confirmation, so non-entry followed under Art. 108(1)(a) BGG.
