Question juridique clé
Whether the administrative court appeal could proceed despite non-payment of the ordered advance costs.
Solution extraite
The appeal could not proceed; the court did not enter into the merits after the advance was not paid within the set period.
Motifs extraits
The prior order warned that failure to pay the CHF 500 advance within 14 days would lead to non-entry. Since the deadline expired unused, the court had to act accordingly under the applicable procedural rule.
