Question juridique clé
Whether the social-insurance appeal was admissible despite failure to pay the full cost advance on time.
Solution extraite
No. The appeal was inadmissible because the appellant did not pay the full advance within the set deadlines and did not seek waiver, instalments, or legal aid.
Motifs extraits
After two reminders and an explicit warning of inadmissibility, only partial payments were made. Under Art. 62(3) LTF, non-payment of the advance leads to inadmissibility; the simplified procedure under Art. 108(1)(a) LTF applied.
