National Pork Producers Council v. Ross

Proposition 12 conditions market access on compliance with California's animal welfare standards rather than directly regulating production practices outside California's borders, distinguishing it from laws that purport to control conduct occurring wholly within other states. The plurality reasoned that the dormant Commerce Clause does not prohibit a state from setting conditions on goods sold within its market, even when those conditions indirectly pressure out-of-state producers to change nationwide practices. The downstream economic pressure falls short of the impermissible extraterritorial regulation the doctrine prohibits. California's legitimate local interest in animal welfare, applied uniformly to all pork sold in the state regardless of origin, satisfied the Pike balancing test despite the significant burden on interstate commerce, because the state was not discriminating against out-of-state producers but rather enforcing uniform market-access requirements. The fractured majority thus upheld the law by treating market-conditioning as categorically distinct from direct regulation of out-of-state conduct, permitting states broader latitude to impose welfare and safety standards as conditions of market participation.
