Questione giuridica chiave
Whether the constitutional complaint could be heard despite non-payment of the court advance within the extended deadline.
Decisione estratta
No. Because the advance costs were neither paid nor properly evidenced within the non-extendable period, the complaint had to be declared inadmissible.
Motivazione estratta
After a warning under Art. 62(3) BGG, the appellant did not comply with the advance-payment requirement; under Art. 117 in conjunction with Art. 108(1)(a) BGG, the court had to refuse entry.
