Kernrechtsfrage
Whether new and enlarged claims filed only in a supplementary brief after the appeal deadline were admissible before the Federal Administrative Court.
Extrahierter Entscheid
The appeal deadline under the Administrative Procedure Act is not extended by a later deadline to supplement the reasoning; claims define the dispute and cannot generally be enlarged later.
Extrahierte Begründung
Art. 52 PA requires the notice of appeal to contain the conclusions within the legal deadline. A later opportunity to supplement reasoning under Art. 53 PA does not reopen the time limit for new or broader claims. The elements emerging from the Bülach criminal judgments did not justify an exception.
