Key legal question
Whether the civil appeal could be entered into despite non-payment of the advance on costs.
Extracted holding
No. Because the required advance on costs was not paid within the final extended deadline, the appeal could not be entertained.
Extracted reasoning
Under Art. 62(3) BGG, failure to pay the advance on costs after expiry of the set deadline leads to non-entry under the summary procedure of Art. 108(1)(a) BGG.
