Key legal question
Whether the federal appeal had to be entered into after the appellants failed to pay the advance costs within the non-extendable deadline.
Extracted holding
No. The appeal was not admitted because the advance costs were neither paid in cash nor duly evidenced as paid by account debit within the deadline.
Extracted reasoning
After a warning under Art. 62(3) BGG and an unextendable grace period, the appellants still did not provide the required advance payment or proof of timely payment. Non-entry followed under Art. 108(1)(a) BGG despite their later submission.
