The egg industry has largely complied with the law. Despite the resounding success at the ballot box, the pork industry unsuccessfully sued to block implementation of the law. In June 2021, the
Supreme Court of the United States rejected a lawsuit from the
North American Meat Institute to stop the law. The Meat Institute had argued that Prop 12 violated the
Commerce Clause of the
US Constitution, but this argument was rejected because Prop 12 holds in-state and out-of-state producers to the same standard. On January 25, 2022, a judge ordered a temporary halt to enforcement of the prohibition on pork from gestation crates, for 180 days, pending development of final regulations by the
California Department of Food and Agriculture, to give producers more time to comply. The CDFA also needed more time to comply with a lawsuit filed by animal activists, who wanted to increase stringency of the regulations. The
American Farm Bureau Federation and the
National Pork Producers Council again asked the Supreme Court to overturn the law, in another lawsuit similar to the ones that were previously rejected. As of 2024,
House Republicans are attempting to overrule Proposition 12 through the
United States farm bill. No new farm bill has been passed as of November 2024. ==See also==
