Question juridique clé
Whether the subsidiary constitutional complaint could be entered into despite non-payment of the court advance within the grace period.
Solution extraite
No. Because the advance was neither paid in cash nor duly evidenced as paid within the grace period, the court had to refuse entry into the complaint under the warning given.
Motifs extraits
After the non-extendable grace period under Art. 62(3) BGG expired without payment or proof of timely debit, the sanction of non-entry followed under Art. 108(1)(a) BGG.
