In an Amicus Brief filed with the U.S. Supreme Court, The North American Meat Institute (Meat Institute) urged the Court to reverse a lower court's judgement upholding California's Proposition 12 (Prop 12 or the law).
"A fundamental premise of our federal system is that each State is a sovereign laboratory of democracy, but only within its own borders," the Meat Institute said in its brief. "As a result, the Constitution denies California the authority to dictate the conditions under which farm animals must be housed outside California's borders."
