Question juridique clé
Whether the complaint could be entered into despite non-payment of the advance costs and the failed request for extension/legal aid treatment.
Solution extraite
No. The filing did not meet the requirements for late-stage relief, and the advance costs were not paid within the final deadline.
Motifs extraits
Under Art. 62(1) BGG an appellant must generally pay advance costs. After the non-extendable grace period expired, only a properly substantiated request with sufficient evidence of financial situation could avert non-entry; the appellant's submission did not satisfy these requirements.
