Key legal question
Whether the constitutional complaint could be entered into despite non-payment of the court advance on costs within the final deadline.
Extracted holding
No; because the advance on costs was not paid or duly evidenced within the non-extendable deadline, the complaint was not admitted.
Extracted reasoning
After a formal reminder under Art. 62(3) BGG, the complainant still did not pay the advance in cash, did not deposit it through a post office for the benefit of the Federal Supreme Court, and did not submit the required debit confirmation for a payment order. Under the threatened consequence, non-entry followed.
