Key legal question
Whether the complaint could be entered into despite non-payment of the required cost advance.
Extracted holding
No. Because the appellant neither paid the advance nor proved timely debit/transfer as required, the complaint could not be heard.
Extracted reasoning
After an unsuccessful initial order, a non-extendable grace period under Art. 62(3) BGG expired without payment or the required proof of payment; therefore non-entry followed under Art. 108(1)(a) BGG.
