Kernrechtsfrage
Whether the Federal Administrative Court correctly issued a non-entry decision for failure to pay the cost advance.
Extrahierter Entscheid
Yes. The advance order was deemed duly served, the payment deadline expired unused, and no further payment followed.
Extrahierte Begründung
For registered mail, service is deemed completed at the latest on the seventh day after the first delivery attempt if an admission notice was properly left; in case of non-proof, the recipient bears the risk of failure to prove non-receipt of the notice.
