Questione giuridica chiave
Whether the complaint had to be entered into despite non-payment of the court advance.
Decisione estratta
No entry could be made because the required advance was not paid within the set deadline, including the grace period.
Motivazione estratta
The appellant received the payment order, did not react, was granted a statutory grace period with a warning of non-entry, and still failed to pay; therefore the appeal was inadmissible under Art. 108 BGG.
