Eugene Ralph, Gregory Pembo, Helen Robinson, and a number of other citizens and taxpayers (plaintiffs) living in the city of New Orleans (the City) filed suit against the City and its city council (defendants), seeking a declaration that the defendants acted without statutory authority in creating a registry of domestic partnerships and using the registry as the basis for extending health-insurance coverage to the unmarried domestic partners of city employees. Additionally, the defendants sought to enjoin enforcement of the registry and accompanying ordinances. The plaintiffs and defendants filed cross motions for summary judgment, and the plaintiffs filed a motion for default. The trial court denied both of the plaintiffs’ motions, granted the defendants’ motion for summary judgment, and dismissed the complaint. The plaintiffs appealed.
