Key legal question
Whether the federal complaint had to be entered into despite non-payment of the court advance within the non-extendable deadline.
Extracted holding
No. Because the advance costs were neither paid nor duly proven as timely paid, the complaint could not be considered.
Extracted reasoning
The appellant ignored the warning under Art. 62(3) BGG and did not comply with the extended deadline or provide the required payment confirmation; under Art. 117 BGG in conjunction with Art. 108(1)(a) BGG, non-entry followed.
