City of Norwalk v. City of Cerritos
Annotate this CaseThe case revolves around a dispute between two cities, Norwalk and Cerritos, both located in California. In 1974, Cerritos enacted an ordinance restricting commercial and heavy truck traffic to certain major arteries within the city. The ordinance was amended in 2019 and 2020, resulting in the removal of one of these arteries. Consequently, Norwalk sued Cerritos, arguing that the ordinance created a public nuisance by diverting extra truck traffic through Norwalk and thus causing various "adverse effects" linked to heavier traffic flow. Cerritos claimed immunity under Civil Code section 3482, which shields a city from public nuisance liability for actions "done or maintained under the express authority of a statute". The Court of Appeal of the State of California Second Appellate District found that the Vehicle Code explicitly authorized cities to regulate the use of their streets by commercial or heavy vehicles. Therefore, the court held that Cerritos was immune from liability for the public nuisance of diverting traffic into Norwalk. The court stated that the immunity conferred by Civil Code section 3482 applied not only to the specific act expressly authorized by the statute, but also to the consequences that necessarily stemmed from that act. The court affirmed the judgment in favor of Cerritos.
