Key legal question
Whether the appeal could proceed despite non-payment of the court-ordered advance costs within the extended deadline.
Extracted holding
No. Because the advance costs were not paid even within the statutory grace period, the court had to refuse entry on the appeal.
Extracted reasoning
Under Art. 62(3) BGG, failure to pay the advance costs within the extended period entails non-entry; the simplified procedure under Art. 108(1)(a) BGG applied.
