Question juridique clé
Whether the administrative appeal had to be declared inadmissible because the ordered advance on costs was not paid within the deadline.
Solution extraite
Yes. After the deadline expired without payment of the advance, the appeal had to be declared inadmissible under the procedural rules.
Motifs extraits
The case remained governed by the former OJ because the challenged judgment predated 1 January 2007. Since the appeal was filed after 30 June 2006, the proceedings were no longer free in AI matters. The appellant was warned twice that failure to provide security would lead to inadmissibility, but he did not pay.
