Question juridique clé
Whether the administrative law appeal could be entered into despite non-payment of the ordered cost advance.
Solution extraite
No. Because the cost advance was not paid and no additional grace period had to be granted in this case, the appeal could not be considered.
Motifs extraits
The court relied on the prior warning in its order and held that the duty to set a grace period under Art. 62(3) BGG did not apply here, so it had to decide as announced.
