Questione giuridica chiave
Whether the appeal could be entered into despite non-payment of the required advance on costs.
Decisione estratta
No entry was possible because the appellant did not pay the advance within the original deadline or the statutory grace period.
Motivazione estratta
After the legal-aid request was refused as the appeal lacked prospects, the advance of CHF 750 was set and then extended once more. The appellant still failed to pay, and non-collection of the notice did not prevent valid service under Art. 44(2) BGG.
