Question juridique clé
Whether the appeal could be heard despite the appellant's failure to pay the required court advance in time.
Solution extraite
No. Because the advance payment was neither paid in cash nor duly credited within the grace period, the court had to refuse to enter the appeal.
Motifs extraits
The appellant had been warned under Art. 62(3) BGG that non-payment would lead to non-entry. He did not comply and also failed to provide the required debit confirmation after an electronic payment order, so non-entry followed under Art. 108(1)(a) BGG.
