Questão jurídica principal
Whether the subsidiary constitutional complaint is admissible despite non-payment of the court advance within the final deadline.
Decisão extraída
The complaint is inadmissible because the required advance was neither paid in cash nor timely credited and proven by bank/post confirmation.
Fundamentação extraída
After a non-extendable grace period under Art. 62(3) BGG, the complainant still did not make the advance payment or provide the required proof of timely debit; under Art. 108(1)(a) BGG the court therefore had to refuse entry.
