Question juridique clé
Whether the federal appeal could be entered into despite non-payment of the advance on costs within the set deadline.
Solution extraite
The court did not enter into the appeal because the appellant failed to pay the advance on costs within the extended time limit.
Motifs extraits
Under Art. 62(3) BGG, failure to pay the required advance on costs permits non-entry. The appellant's later submission claiming inability to pay did not alter the result, especially since legal aid had already been refused as hopeless.
