Key legal question
Whether the Federal Administrative Court could enter into the appeal despite non-payment of the ordered advance on costs.
Extracted holding
No. The appeal was clearly unfounded because the appellant could have paid using the information on the invoice and should have clarified any difficulty in time.
Extracted reasoning
Although the orange Swiss payment slip was unusable for an overseas payment, the invoice contained the necessary international transfer details. The appellant let the deadline pass without reacting, which was not acceptable.
