Key legal question
Whether the federal appeal was admissible despite non-payment of the court advance within the non-extendable grace period.
Extracted holding
The appeal was not admitted because the appellant failed to pay the advance costs or prove timely payment by debit confirmation within the deadline.
Extracted reasoning
After a warning under Art. 62(3) BGG, non-payment of the advance costs required non-entry under Art. 108(1)(a) BGG.
