The United States Supreme Court on Monday declined to hear challenges to two of California’s most wide-ranging and controversial animal rights laws: bans on foie gras and eggs from caged hens. It also declined to a hear a similar challenge to a caged-hen law in Massachusetts. The decisions leave lower court rulings intact and ensures the policies will stand, at least for now.

Some background: The dispute started with California’s Prevention of Farm Animal Cruelty Act, a 2008 ballot measure also known as Proposition 2, which mandated that the state’s farm animals could not be confined “in a manner that does not allow them to turn around freely, lie down, stand up, and fully extend their limbs.” Though the law applied to all livestock, it specifically affected pigs, veal calves, and egg-laying hens, which tend to be raised in cramped quarters. That decision caused upheaval in the American egg industry, where the vast majority of commercial eggs are still produced by hens crammed into cages no larger than a sheet of paper.

After Proposition 2’s passage, California egg producers argued that the new law put them at a disadvantage compared to other states that weren’t subject to the same rules. So the state legislature successfully moved to ban all eggs from caged hens—regardless of where they are laid. In 2014, that prompted a number of other states—Missouri was the lead plaintiff, but Iowa, and other egg-laying states also signed on—to sue. Their argument was that Proposition 2 violated the Egg Products Inspection Act (EPIA), the federal law that oversees egg production, as well as the Interstate Commerce Clause, a provision in the U.S. Constitution that gives the federal government power to limit the power of individual states “to erect barriers against interstate trade.” (The New Food Economy’s Jessica Fu has more on the history of this case.)
