The Iowa Supreme Court will decide whether the ordinance used to confine a Des Moines dog for two years as a dangerous animal is unconstitutional. The court will accept briefs Tuesday in the case of Helmers v. City of Des Moines, which concerns a dog named Pinky whom the city deemed to be dangerous and impounded for two years after she injured a neighbor's cat during a fight.The city moved to have Pinky destroyed, but instead she remained confined at the Animal Rescue League of Iowa, which contracts with the city, while her case worked its way through the court system. Pinky was released in April after the Iowa Court of Appeals ruled in the dog's favor by finding that the law is unconstitutionally vague.In a concurrence with the majority opinion, Appeals Court Judge Richard Doyle wrote that "the city of Des Moines has been unwavering in its mission to kill Pinky."The city appealed the decision to Iowa's high court, which will have the final say on the constitutionality of the ordinance in its current form.Lawyers for Helmers argue Pinky was improperly seized from her previous owners in violation of the city's ordinance and without notice or a declaration that she was dangerous. They say the seizure violates due process and the Fourth Amendment of the U.S. Constitution and Article 1, Section 8 of the Iowa Constitution, which protect against unreasonable search and seizures.
