922 N.W.2d 524
Iowa2019Background
- Cedar Rapids enacted an ordinance authorizing an automated traffic enforcement (ATE) system; the city contracted with Gatso USA to operate cameras/radar and assemble violation packages; Gatso received contingency fees per paid violation and millions in payments.
- Notices were mailed to vehicle owners (printed with the city logo); administrative hearings before volunteer "administrative hearing officers" were available; vehicle owners could alternatively request the city file a municipal-infraction action in small-claims court.
- IDOT promulgated restrictive ATE rules and later issued an evaluation ordering removal/movement of several Cedar Rapids cameras; the Iowa Supreme Court later held the IDOT rules invalid in a separate case, but the IDOT evaluation informed factual debate.
- Plaintiffs (class action) challenged the ATE program on multiple grounds under the Iowa Constitution: substantive due process, equal protection, privileges and immunities, unlawful delegation to a private vendor, preemption by state law/IDOT rules, procedural due process, and unjust enrichment.
- The district court granted summary judgment for defendants; the Iowa Supreme Court (on rehearing) affirms the district court in all material respects, applying a deferential-but-not-toothless rational-basis review under state law.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Substantive due process (ATE vs. public-safety fit) | ATE placement, IDOT findings, and rising citation counts show no real safety purpose and that program is revenue-driven and arbitrary. | ATE advances legitimate safety interest; cities may use cost‑effective enforcement; record does not show irrationality. | Court: No substantive-due-process violation; record is debatable but city made a permissible policy choice. |
| Right to travel (interstate/intrastate) | Cameras disproportionately burden nonresidents; intrastate travel is a fundamental right and is infringed. | Traffic regulations do not implicate right to travel in the constitutional sense; no substantial/direct burden. | Court: No infringement of travel right; apply rational-basis review with heightened scrutiny available in name only. |
| Equal protection / privileges & immunities (classifications) | Practical implementation excludes semi-trailer and government vehicles and treats out-of-state owners differently, irrationally undermining safety goal. | Exclusions result from database/cost/operational choices; it's rational to adopt cost-effective system and allow written appeals for nonresidents. | Court: Plaintiffs failed to show irrational classification as a matter of law; city’s cost/administrative rationale is realistically conceivable. |
| Preemption / procedural due process (municipal-infractions scheme) | ATE's administrative process conflicts with Iowa Code ch. 364 and exclusive district-court jurisdiction; notices and procedures diverge from statutory municipal-infraction requirements. | Ordinance provides an optional administrative forum but preserves right to compel municipal-infraction filing; voluntary pre-filing payment process is compatible with statute. | Court: No implied conflict preemption; ordinance harmonized with statute; Mathews balancing satisfied because small-claims option preserved. |
| Unlawful delegation to private vendor (Gatso) | Gatso exercises screening/discretion, runs Nlets, mails notices, operates hotline and web portal; private incentives and filtering amount to an unlawful delegation of public power. | Gatso performs ministerial tasks; police officers approve/reject violation packages; city sets business rules; volunteers act on behalf of city. | Court: No unlawful delegation in the screening, Nlets access, notice mailing, or volunteer hearing use; those tasks are ministerial and subject to police review. |
| Calibration-related delegation / evidence issues | Calibration practices and any private control over calibration may reflect an unlawful delegation or create due-process problems. | Calibration is ministerial; city police perform calibration and oversight. | Court: On rehearing the court affirms district court judgment; the court does not resolve calibration delegation issue (division of opinions left district-court result intact). |
| Unjust enrichment | Revenues from an unlawful program unjustly enrich city/vendor. | Ordinance and implementation are lawful. | Court: Because plaintiffs' statutory/constitutional challenges fail, unjust-enrichment claim fails. |
