Question juridique clé
Whether the constitutional complaint had to be admitted despite the unpaid cost advance.
Solution extraite
No. Because the appellant did not pay the advance even within the grace period, the Court could not enter into the complaint.
Motifs extraits
Under Art. 62(3) BGG and the summary procedure of Art. 108(1)(a) BGG, non-payment of the required advance after the extended deadline leads to non-entry.
