Key legal question
Whether the constitutional complaint had to be entered into despite the complainant's failure to pay the court-ordered cost advance within the final deadline.
Extracted holding
No; because the cost advance was neither paid in cash nor properly credited and evidenced within the non-extendable deadline, the complaint could not be considered.
Extracted reasoning
After a warning under Art. 62(3) BGG, the complainant still failed to perform the required advance payment or provide proof of timely debit, so the sanction of non-entry applied under the summary procedure.
