Frost v. City of Sioux City, Iowa
Summary: In this case, the City of Sioux City had adopted a local ordinance that made it "unlawful for any person to own, possess, keep, exercise control over, maintain, harbor, transport or sell within the City ... any pit bull." The ordinance goes on further to define pit bulls based on appearance and certain listed characteristics. Plaintiffs alleged that the ordinance is unconstitutional under the Due Process and Equal Protection Clauses of the Fourteenth Amendment because it: (1) is unconstitutionally vague; (2) violates their rights under the equal protection clause; and (3) violates their rights under the due process clause, both in substance and procedure. Here, the district court found that the due process and equal protection claims survived the defendant's motion to dismiss, but found that the ordinance was not facially unconstitutionally vague. As a result, defendants' Motion to Dismiss was DENIED in part and GRANTED in part. Plaintiffs' claim that the ordinance is unconstitutionally vague was DISMISSED, and plaintiffs may proceed with their remaining equal protection clause and due process clause claims.
