Question juridique clé
Whether the Federal Department's administrative appeal was timely despite defective notification of the cantonal judgment.
Solution extraite
The appeal was timely because the judgment had to be notified to the Department, and the 30-day period ran from the later actual notification.
Motifs extraits
As a legally entitled appellant, the Department had to receive notice of the decision; since it was not initially notified, the time limit started only upon later service.
