Questione giuridica chiave
Whether the complaint had to be entered into despite non-payment of the cost advance.
Decisione estratta
No. Because the appellant neither paid the advance in time nor proved timely debit/transfer, the complaint could not be examined.
Motivazione estratta
After the unsuccessful expiry of the non-extendable grace period under Art. 62(3) BGG, non-entry was mandatory under Art. 108(1)(a) BGG.
