Key legal question
Whether the federal complaint had to be entered into despite the missing advance payment of costs.
Extracted holding
No. The appellant did not pay the advance within the non-extendable deadline and did not prove timely payment by account debit, so the complaint was not admitted.
Extracted reasoning
After notice under Art. 62(3) BGG, the appellant neither paid in cash nor at a post office counter nor provided the required debit confirmation; therefore non-entry followed under Art. 108(1)(a) BGG.
