Question juridique clé
Whether the federal appeal is admissible despite non-payment of the required cost advance.
Solution extraite
The appeal is inadmissible because the appellant did not pay the advance within the fixed deadlines and did not timely prove that the amount had been debited from her postal or bank account.
Motifs extraits
After an initial deadline and a non-extendable grace period, no payment was made. Under Art. 48(4) LTF, no timely debit certificate was produced; therefore the condition for proceeding was not met.
