Question juridique clé
Whether the constitutional complaint could be entered into despite non-payment of the ordered cost advance within the final deadline.
Solution extraite
No. Because the appellant neither paid the advance nor proved timely payment by debit confirmation, the complaint was not admissible for consideration.
Motifs extraits
After a non-extendable grace period under Art. 62(3) BGG and the warning of non-entry, failure to make or prove payment required non-entry under Art. 117 BGG in conjunction with Art. 108(1)(a) BGG.
