Question juridique clé
Whether the public-law appeal was admissible and whether new legal arguments could be raised before the Federal Supreme Court.
Solution extraite
The appeal was admissible; because the cantonal court had to apply the law ex officio and had full review powers, new legal arguments not amounting to arbitrariness could be considered.
Motifs extraits
The court applied the subsidiarity and exhaustion rules under the former OJ and held that cantonal social-insurance subsidy rules were autonomous cantonal law. It further found that the Geneva appellate court's free legal review allowed new points of law.
