The Supreme Court issued its decision on May 11, 2023. In a 5–4 ruling, the court upheld the lower court ruling in dismissing the lawsuit and ruling Proposition 12 was legal. In Section IV-B, joined only by a plurality, Gorsuch suggested that courts should only be able to use the comparative balancing test from
Pike when the variables to be balanced can be measured and compared directly. To him, the comparison of economic cost to humane treatment was "incommensurable." When the Justices' votes and justifications are counted, Proposition 12 was upheld by a majority of 5-4. However, while the majority opinion clearly upheld Proposition 12, there was no single rationale for this outcome that was joined by a majority of the Justices. Three of the five majority Justices (Gorsuch, Thomas, and Barrett) upheld Proposition 12 because they believe that the burdens and benefits at issue in the case were not capable of being balanced by a court. In other words, this plurality would not apply
Pike to cases in which the burdens and benefits are incommensurate. A separate but overlapping group of four of the five majority Justices (Gorsuch, Thomas, Sotomayor and Kagan) believed that petitioners had failed to plausibly allege a burden on interstate commerce in the first place. Justices Sotomayor and Kagan also wrote an additional separate concurrence to clarify that they do believe that it is possible for such burdens and benefits to be weighed in a
Pike analysis. A minority believed that the case should be remanded to the lower court for further factual development in order to decide whether petitioners had sufficiently stated a claim under
Pike and decide whether the "'burden . . . is clearly excessive in relation to the putative local benefits.'" Analyst
Ian Millhiser wrote that the case was a rare instance of the Court reducing the judiciary's ability to block state laws. == See also ==
