The Supreme Court will hear “the bacon case” on Oct. 11. National Pork Producers Council v. Ross challenges California’s Prevention of Cruelty to Farm Animals Act, also known as Proposition 12. It’s an ill-conceived and unconstitutional 2018 law that attempts to use the Golden State’s enormous market power as leverage to regulate pig farming nationwide.

California lawmakers often presume they know what’s best—in this case for pigs and pig farmers across the country. State regulators are currently training inspectors to disperse across the nation to enforce California’s rules. Out-of-state farmers must certify that their products are compliant with Proposition 12 to be sold in California.
