Questione giuridica chiave
Whether the appeal had to be entered into despite non-payment of the court advance and failed service pickup.
Decisione estratta
The appeal could not be considered because the advance was not paid within the extended time limit; the notice was deemed served after the unsuccessful delivery attempt.
Motivazione estratta
Under Art. 44(2) BGG, a notice requiring signature is deemed served no later than seven days after the first unsuccessful delivery attempt. As the advance was not paid within the additional deadline, Art. 62(3) BGG required non-entry in simplified procedure under Art. 108(1)(a) BGG.
