Question juridique clé
Whether the administrative appeal against the cantonal judgment was filed in time.
Solution extraite
The appellant did not prove a timely filing in 2003; the 2008 filing was therefore out of time.
Motifs extraits
The burden of proving timely filing lay with the appellant. The submitted copy of a pleading and a postal receipt did not establish that the receipt related to a Bundesgericht submission; the alleged filing was also implausible and no further evidence was warranted.
