Question juridique clé
Whether the second public-law appeal against the reconsideration refusal was admissible
Solution extraite
The reconsideration request did not trigger a new merits decision; the appeal attacked only the refusal to reconsider and did not contest that refusal with proper reasoning.
Motifs extraits
A party may challenge only the alleged lack of grounds for reconsideration when the authority declines to reopen a case; here the second filing raised only merits arguments.
