Key legal question
Whether the complaint could be entered into despite non-payment of the required advance costs within the final deadline.
Extracted holding
No. Because the appellant neither paid the advance costs nor proved timely payment by debit confirmation, the complaint had to be dismissed from consideration.
Extracted reasoning
After a non-extendable final deadline under Art. 62(3) BGG, non-compliance triggers non-entry under Art. 117 BGG in conjunction with Art. 108(1)(a) BGG.
