Florida Lime & Avocado Growers, Inc. v. Paul, Director, Dept. of Agriculture of California

California barred the sale of avocados with less than 8 percent oil content, a stricter standard than the federal rule that permitted Florida growers to sell avocados with lower oil content. Florida Lime & Avocado Growers (plaintiff), affected by the California rule, sued California's agriculture director, Paul (defendant), in federal court to enjoin enforcement, arguing the state rule was preempted by federal law and violated the Equal Protection and Commerce Clauses; the district court denied an injunction, and the growers appealed to the Supreme Court.
