Key legal question
Whether the appeal had to be entered into despite non-payment of the ordered cost advance within the extended deadline.
Extracted holding
No. Because the appellant still did not pay the required advance after the grace period, the appeal could not be considered.
Extracted reasoning
Under Art. 62(3) BGG and the simplified procedure of Art. 108(1)(a) BGG, failure to pay the advance within the set time limit leads to non-entry.
