Question juridique clé
Whether the public-law appeal had to be entered into despite non-payment of the advance on costs.
Solution extraite
No. Because the advance on costs was not paid within the time limit, the appeal was inadmissible.
Motifs extraits
The Federal Supreme Court held that the advance had been ordered under former Art. 150 OJ and remained unpaid; under Art. 150 para. 4 OJ the appeal must therefore be declared inadmissible, with costs borne by the appellant.
