Association des “leveurs de Canards et D’oies du Queb”c v. Bonta

(1) Whether a state may avoid express ingredient preemption under the Poultry Products Inspection Act by banning the sale of poultry products based on the only way their primary ingredient can be produced; (2) whether a state law that makes it physically impossible to produce and sell a poultry product in compliance with both state and federal law is preempted under the doctrine of impossibility preemption, or whether a state may avoid preemption under the "stop-selling" rationale this court rejected in Mutual Pharmaceutical Co. v. Bartlett; and (3) whether a state"s sales ban of wholesome poultry products based exclusively on the farming practice by which the animals were raised in other states and countries violates this court"s dormant commerce clause doctrines.
