Key legal question
Whether the federal complaint must be entered into despite non-payment of the court-ordered advance on costs within the non-extendable deadline.
Extracted holding
No; the complaint could not be considered because the advance on costs was not paid even within the additional deadline.
Extracted reasoning
Under Art. 62(3) BGG, failure to pay the advance on costs within the set non-extendable deadline permits non-entry; the case was decided in simplified procedure under Art. 108(1)(a) BGG.
