Key legal question
Whether the appeal could be entertained despite non-payment of the required advance of costs within the extended deadline.
Extracted holding
No. Because the appellant did not pay the advance of costs even within the non-extendable grace period, the Federal Supreme Court had to refuse entry on the appeal in summary proceedings.
Extracted reasoning
Under Art. 62 BGG, the appellant must pay an advance of costs; if it is not paid within the set time limit and grace period, the court does not enter on the filing. Service of the orders was deemed effected under Art. 44 Abs. 2 BGG.
