Question juridique clé
Whether the complaint could be entered into despite non-payment of the court advance within the non-extendable grace period.
Solution extraite
No. Because the appellant neither paid the advance in cash nor provided the required proof of timely debit after a payment order, the court had to refuse entry.
Motifs extraits
The advance was demanded under threat of non-entry; failure to comply within the grace period triggered non-entry under Art. 62(3) BGG in conjunction with Art. 108(1)(a) BGG.
