Question juridique clé
Whether the denial of justice complaint regarding complementary insurance was admissible in this public-law appeal
Solution extraite
It was inadmissible because the relevant relationship was governed by private insurance law, not social-insurance law.
Motifs extraits
Disputes over complementary insurance fall under the LCA and must be brought by civil-law appeal; the alleged delay in the cantonal proceedings did not show unjustified delay in any event.
