Key legal question
Whether the appeal had to be entered into despite non-payment of the court advance.
Extracted holding
No. Because the advance was not paid or duly evidenced within the non-extendable deadline, the court had to decline to hear the appeal.
Extracted reasoning
After the warning under Art. 62(3) BGG and the refusal to extend time, the appellant neither paid the advance in cash nor showed timely debit confirmation; under Art. 108(1)(a) BGG non-entry followed.
