Key legal question
Whether the complaint could be entered into despite non-payment of the court advance within the final deadline.
Extracted holding
No. Because the advance was neither paid in cash nor validly credited and proved within the non-extendable deadline, the complaint had to be dismissed without entry.
Extracted reasoning
After a reminder under Art. 62(3) BGG with threat of non-entry, the appellant still failed to provide timely payment or proof of timely debit; under Art. 108(1)(a) BGG the president could therefore decline to enter.
