National Meat Association, et al. v. Brown, 599 F.3d 1093 (9th Cir. 2010)

(plaintiff subject to California laws prohibiting slaughter-for consumption of animals that cannot stand or walk; CA laws are not pre-empted by federal law; all such animals must be immediately euthanized; CA and other states not simply limited to excluding animals from slaughter on a species-wide basis - trial court's ruling that state may ban slaughter of certain species, but that once a state allows a species to be slaughtered, it cannot impose further restrictions is "hogwash").
