Question juridique clé
Whether the public law appeal was admissible despite non-payment of the advance on costs within the time limits
Solution extraite
The appeal was inadmissible because the required advance on costs was not paid within the deadlines and no timely proof of debit was produced.
Motifs extraits
After two payment deadlines expired without payment, the conditions of Art. 48(4) LTF were not met; therefore the appeal had to be declared inadmissible under Art. 62(3) third sentence LTF.
