Key legal question
Whether the appeal could be entered into despite non-payment of the advance costs within the additional deadline.
Extracted holding
No. Because the appellant did not pay the required advance costs within the extended time limit, the court declined to enter on the appeal.
Extracted reasoning
Under Art. 62(3) BGG, failure to pay the advance costs after the grace period leads to non-entry under Art. 108(1)(a) BGG.
