Question juridique clé
Whether the constitutional complaint is admissible despite non-payment of the required advance on costs.
Solution extraite
No. Because the advance on costs was not paid within the final extended deadline, the complaint had to be declared inadmissible under the simplified procedure.
Motifs extraits
The court had granted an ultimate extension and expressly warned that failure to pay would lead to inadmissibility. Since no payment was made, Art. 62(3) LTF required non-entry.
