Key legal question
Whether the appeal had to be admitted despite non-payment of the court advance within the extended deadline.
Extracted holding
The appeal could not be entered into because the appellant neither paid the advance nor proved timely debiting/transfer as required.
Extracted reasoning
After a non-extendable grace period under Art. 62(3) BGG, failure to comply with the advance-payment order triggers non-entry under Art. 108(1)(a) BGG.
