Key legal question
Whether the appeal should be entered into despite non-payment of the ordered cost advance within the grace period.
Extracted holding
No. Because the appellant did not pay the required advance even within the extended deadline, the appeal could not be considered.
Extracted reasoning
Under Art. 62(3) BGG, failure to pay the cost advance within the granted grace period leads to non-entry; the case was decided in the simplified procedure under Art. 108(1)(a) BGG.
