Question juridique clé
Whether the debtor's filing was directed against an appealable administrative decision under social insurance law.
Solution extraite
The filing was not directed against an appealable decision; it challenged a debt collection notice and no opposition decision had yet been issued by the insurer.
Motifs extraits
Only decisions on objection/opposition under the LPGA can be appealed. A debt collection notice or the initiation of enforcement by the insurer is not, by itself, an appealable administrative decision in this procedure.
