Iowa Pork Producers Association v. Bonta

(1) Whether a party alleging that California's Proposition 12 "which enacts a pork sales ban to regulate the manner in which pigs are housed in states across the country" discriminates against interstate commerce, both directly and under Pike v. Bruce Church, states a claim; and (2) whether lower federal courts evaluating fractured opinions from this court consider all justices' opinions to determine the majority position on a legal issue, or instead are limited to consider only opinions concurring in the result.
