On November 6, 2018, California voters passed Proposition 12 which goes into effect January 1, 2022. The bill increased regulations on egg, pork, and veal producers both in the state of California and any out of state producers that want to sell products in
California. Prop 12 was written, funded, and marketed by the Humane Society of the United States and their "Prevent Cruelty California" coalition.
At this time, only 1% of pork producers comply with the arbitrary housing requirements of Prop 12. When it goes into effect at the beginning of 2022, a majority of the nation's pork producers will not be allowed to sell its products in California.
The American Farm Bureau Federation and the National Pork Producers Council have jointly filed an appeal with the U.S. Court of Appeals for the Ninth Circuit to ask that Prop 12 be ruled invalid. The appeal claims that Prop 12 is unconstitutional and seeks
to allow California to regulate states outside its governance by requiring producers to abide by the state's own regulations in order to do business there.
