In a ruling dated April 29, 2005, three judges from the United States Eighth Circuit Court of Appeals unanimously voted to reverse the district court's decision. The appellate court dispensed with each ground relied upon by the district court, and ruled that the law was not unconstitutional on its face. The court ruled that there exists no constitutional right to "live where you want." Therefore, the state only needed to show that the statute rationally advanced some legitimate governmental purpose. Plaintiffs acknowledged that the law was enacted to promote the safety of children, and that this was a legitimate legislative goal. They argued, however, that the law is irrational because there is no scientific evidence to support the conclusion that residency restrictions will enhance the safety of children. The court rejected this argument as well, noting that state policymakers are entitled to employ "common sense" when making a determination that "limiting the frequency of contact between *** offenders and areas where children are located is likely to reduce the risk of an offense."
Two judges agreed that the law did not amount to an ex post facto punishment. They ruled that plaintiffs did not establish by "clearest proof" that the law's punitive effect overrides the legislature's "legitimate intent to enact a nonpunitive, civil regulatory measure that protects health and safety" of the state's citizens.
Municipalities and counties have enacted their own versions of residency restrictions. For example, in Des Moines, Iowa, the state's largest city, officials added parks, libraries, swimming pools, and recreational trails to the list of protected buffer zones. A report in the Des Moines Register on January 22, 2006, reported that since the state's residency law took effect, more *** offenders are eluding tracking by authorities. The paper reported that 298 *** offenders were unaccounted for in January 2006, compared to 142 on June 1, 2005. Critics charge that the law has forced some *** offenders to become homeless; others may lie and say that they are homeless to hide the fact that they are not complying with the law. Iowa has approximately 6,000 registered *** offenders.
