Key legal question
Whether the appeal could be entered into after the advance on costs was not paid within the grace period.
Extracted holding
No. Because the advance on costs was not paid even within the extended deadline, the appeal had to be dismissed by non-entry in simplified proceedings.
Extracted reasoning
Under Art. 62(3) BGG, failure to pay the required advance of costs after warning permits non-entry; the court therefore did not examine the merits.
