Key legal question
Whether the constitutional complaint could be entered into despite non-payment of the advance costs within the set deadline.
Extracted holding
No. Because the advance costs were neither paid nor properly evidenced within the non-extendable deadline, the complaint could not be heard.
Extracted reasoning
After a warning under Art. 62(3) BGG and reference to Art. 48(4) BGG, the complainant still did not make the required payment or provide the required proof of timely debit; non-entry followed under Art. 108(1)(a) BGG.
