Key legal question
Whether the appeal should be entered into despite non-payment of the ordered cost advance within the additional deadline.
Extracted holding
No entry must be made because the appellant did not pay the ordered cost advance within the extended deadline.
Extracted reasoning
Under Art. 62(3) BGG, failure to pay the advance within the grace period permits non-entry; the appeal was therefore dismissed in simplified procedure under Art. 108(1)(a) BGG.
