Question juridique clé
Whether the Federal Administrative Court could declare the appeal inadmissible because the outstanding CHF 12 cost advance was not paid within the time limit.
Solution extraite
Yes. The outstanding amount was paid only after expiry of the deadline, and no excusable impediment justified restoration of the time limit.
Motifs extraits
The appellant had been expressly warned of the consequences and had sufficient time to pay. Any bank error could not justify restitution. Choosing to send a letter to her sister instead of ensuring timely payment was negligence, not an excusable impediment. Lack of French knowledge was likewise insufficient.
