- Decided
Decided 5-4 · May 11, 2023 · Opinion by Justice Gorsuch

- Who it affects
- Pork producers and sellers who want to sell pork in California must meet Proposition 12's confinement standards. For example, an out-of-state producer may need to change its sourcing or animal-housing practices for pork sold in California.
Summary: written with AI from the case record.
What it's about
The Court ruled that the law did not violate the dormant Commerce Clause because it did not intentionally discriminate against out-of-state economic interests, and the pork producers had not stated a valid claim that its interstate-commerce burdens were clearly excessive compared with its local benefits.
The case tested how far a state may use sales rules to advance its own standards when those rules affect businesses outside the state.
Question presented
Whether California's Proposition 12, which bans the in-state sale of pork from animals confined in ways that violate California's standards, violates the dormant Commerce Clause.

What's next
California can continue to enforce Proposition 12. Producers and retailers selling pork in California must account for the law's confinement standards in their supply chains.
