Question juridique clé
Whether the constitutional complaint could be entered into despite non-payment of the required cost advance.
Solution extraite
No. Because the complainant did not pay the advance within the non-extendable deadline and did not prove timely payment by debit confirmation, the complaint was not entered into.
Motifs extraits
After warning under Art. 62(3) BGG, the advance was neither paid in cash to the Federal Supreme Court nor deposited through a post office counter, and no debit confirmation was submitted within the deadline; non-entry followed under Art. 117 BGG in conjunction with Art. 108(1)(a) BGG.
