Question juridique clé
Whether the complaint could be entered into despite non-payment of the advance on costs.
Solution extraite
No; the appeal was not entered into because the advance costs were not paid within the initial deadline or the grace period.
Motifs extraits
The appellant received the first order but did not pay. The follow-up order with a warning was returned uncollected, yet service was deemed effective because she had to expect court mail. Since payment still did not arrive, non-entry followed under Article 108 BGG.
