Question juridique clé
Whether the appellants were entitled to challenge the cantonal law in abstract review

Yes. The private insurers and the association had sufficient virtual concern and a protected interest because they alleged unequal and privileged state competition.
Motifs extraits
Competitors may be legitimized when they claim another market participant is privileged or when special regulatory proximity exists; mere fear of competition is not enough, but that threshold was met here.
