Key legal question
Whether the constitutional complaint could be entered into despite non-payment of the advance on costs within the deadline.
Extracted holding
No. The complaint was not entered into because the advance on costs was neither paid in cash nor duly evidenced as timely paid.
Extracted reasoning
After a warning under Art. 62(3) BGG, the appellant did not satisfy the advance-payment obligation within the non-extendable grace period; under Art. 117 BGG in conjunction with Art. 108(1)(a) BGG, this requires non-entry.
