Key legal question
Whether the appeal could be entered into despite non-payment of the cost advance within the set deadline.
Extracted holding
No. Because the appellant did not pay the cost advance even after the grace period, the Court declined to enter into the appeal.
Extracted reasoning
Under Art. 62(3) BGG, failure to pay the required advance after a deadline extension leads to non-entry; the Court used the summary procedure under Art. 108(1)(a) BGG.
