South Dakota has enacted three preemption statutes. One is applicable to counties (S.D. Codified Laws § 7-18A-36), one to municipalities (section 9-19-20), and one to townships (section 8-5-13). These statutes are otherwise identical, prohibiting all such local governments from passing “any ordinance that restricts possession, transportation, sale, transfer, ownership, manufacture or repair of firearms or ammunition or their components.” Each statute also declares that any ordinance prohibited by the statute is null and void.
There are no cases interpreting these statutes.
