Kernrechtsfrage
Whether the complaint had to be entered into despite the missing cost advance.
Extrahierter Entscheid
No. Because the complainant did not pay the court-ordered advance within the non-extendable deadline, the complaint could not be considered.
Extrahierte Begründung
After prior warning under Art. 62(3) BGG, the advance was neither paid in cash nor properly credited by post/bank transfer with proof of timely debit. Non-entry therefore followed under Art. 108(1)(a) BGG.
