State of Iowa v. Joseph Daniel Huntoon, 20-1405

Background

In June 2009 Huntoon pleaded guilty to four misdemeanors including assault with intent to commit sexual abuse; he received suspended imprisonment and two years’ supervised probation and was subject to a 10‑year special sentence under Iowa Code ch. 903B and ordered to comply with sex‑offender registry laws.
Iowa amended the sex‑offender registry statutes in 2009 (effective July 1), expanding lifetime registration for aggravated offenses; the department of public safety determined in 2017 Huntoon must register for life under Iowa Code § 692A.106(5).
Huntoon moved in 2020 to dismiss the lifetime registration requirement, alleging violations of the Ex Post Facto Clause, procedural due process, and the prohibition on cruel and unusual punishment.
The district court denied his motion, concluding the registry requirements are civil/nonpunitive and citing statutory procedures for modification or release from registration.
On appeal the Court of Appeals affirmed, relying principally on State v. Aschbrenner and related precedents holding chapter 692A is not punitive as to adults and noting the statutory process under § 692A.128.

Issues

Issue	Plaintiff's Argument	Defendant's Argument	Held
Ex post facto: Did post‑conviction amendments increasing registration from 10 years to lifetime violate the Ex Post Facto Clause?	Amended 692A increased the severity of punishment after conviction by imposing lifetime registration.	Chapter 692A is civil/regulatory, not punitive; Aschbrenner controls.	Not a violation; statute is not punitive for adult offenders, so no ex post facto breach.
Applicability of Lathrop (903B special sentence)	Lathrop held a 903B special sentence punitive; Huntoon argues that principle should make the registry punitive.	903B special sentences are distinct from 692A registry requirements; Lathrop does not control chapter 692A.	Court declined to apply Lathrop to chapter 692A (different schemes).
Procedural due process: Is lifetime registration a "complete physical restraint" or otherwise a due‑process deprivation without adequate procedure?	Lifetime registration is mandatory/irrevocable and imposes severe restraints without adequate process.	§ 692A.128 provides a statutory procedure to seek modification or release; Huntoon did not use it.	Due process claim rejected; statutory remedy exists and was not pursued.
Cruel and unusual punishment (Eighth Amendment)	Continued registration causes physical restraints, stigma, and constant monitoring amounting to cruel and unusual punishment.	Registry is nonpunitive under Aschbrenner; Huntoon offers no authority showing Eighth Amendment violation.	Claim rejected for lack of authority and because registration is not deemed punitive for adults.
