Key legal question
Whether the appeal could be entered into despite non-payment of the requested cost advance within the extended deadline.
Extracted holding
No. The appeal had to be left unexamined because the advance payment was not made in time.
Extracted reasoning
Under Art. 62(3) BGG, failure to pay the required advance within the grace period leads to non-entry in simplified procedure under Art. 108(1)(a) BGG; the late-filed settlement submission was disregarded.
