Kernrechtsfrage
Whether receipt of the verification request and reminder for certificate A www was proven
Extrahierter Entscheid
Yes. The Federal Administrative Court arbitrarily ignored decisive evidence; receipt was sufficiently proven.
Extrahierte Begründung
The 4 October 2007 letter, though addressed only to certificates yyy and zzz, enclosed earlier letters concerning all three certificates, and postal research showed delivery on 13 October 2007.
