Opinion of Kavanaugh, J.
as it sees fit with respect to farming, manufacturing, and production practices in that State. Through Proposition 12, however, California has tried something quite different and unusual. It has attempted, in essence, to unilaterally impose its moral and policy preferences for pig farming and pork production on the rest of the Nation. It has sought to deny market access to out-of-state pork producers unless their farming and production practices in those other States comply with California’s dictates. The State has aggressively propounded a “California knows best” economic philosophy—where California in effect seeks to regulate pig farming and pork production in all of the United States. California’s approach undermines federalism and the authority of individual States by forcing individuals and businesses in one State to conduct their farming, manufacturing, and production practices in a manner required by the laws of a different State.
Notably, future state laws of this kind might not be confined to the pork industry. As the amici brief of 26 States points out, what if a state law prohibits the sale of fruit picked by noncitizens who are unlawfully in the country? Brief for Indiana et al. as Amici Curiae 33. What if a state law prohibits the sale of goods produced by workers paid less than $20 per hour? Or as those States suggest, what if a state law prohibits “the retail sale of goods from producers that do not pay for employees’ birth control or abortions” (or alternatively, that do pay for employees’ birth control or abortions)? Ibid.
If upheld against all constitutional challenges, California’s novel and far-reaching regulation could provide a blueprint for other States. California’s law thus may foreshadow a new era where States shutter their markets to goods produced in a way that offends their moral or policy preferences—and in doing so, effectively force other States to regulate in accordance with those idiosyncratic state demands. That is not the Constitution the Framers
