Johnny C. Selby appeals the jury verdict finding him to be a sexually violent preda *250 tor under Iowa Code chapter 229A (2003). He argues that (1) chapter 229A is facially unconstitutional because it violates both due process and equal protection and (2) the jury instruction given in his trial was improper. We affirm.
I. Background Facts and Proceedings
Selby has a history of sexually abusing children. In 1985, he admitted committing lascivious acts with a child. In 1989, he was convicted of one count of second degree sexual abuse. In 2002, he pled guilty to indecent contact with a child.
On October 14, 2003, the State petitioned to have Selby committed as a sexually violent predator pursuant to Iowa Code chapter 229A. The district court found probable cause that Selby was a sexually violent predator. Selby filed a motion to dismiss the State’s petition. His motion was denied. The jury trial began on April 27, 2004.
Two psychologists testified at Selby’s commitment trial. Dr. Anna Salter testified that she measured Selby’s risk of re-offense through three different tests: the Minnesota Sex Offender Screening Tool— Revised (MnSOST — R), the Rapid Risk Assessment for Sex Offense Recidivism (RRASOR), and the Static-99. Under the RRASOR, Selby has a 48.6 percent chance of re-offending in ten years. His risk according to the MnSOST — R was less than 50 percent within six years. According to the Static-99, he has a 52 percent chance of re-offending within fifteen years. Dr. Salter testified that Selby’s risk of re-offending was higher than the estimates indicated by the tests. She further testified that because the tests only measure the risk of re-offending for a particular limited time period, the risk that Selby would re-offend sometime within his lifetime would likely be higher.
Dr. Lynn Maskell testified that Selby’s risk assessments were worthless given his age of fifty-nine years. Dr. Maskell argued that the tests used by Dr. Salter were developed using populations younger than sixty years of age. Thus, such tests could distort the risk presented by a person of Selby’s age. Based on a different study, Dr. Maskell concluded that the risk of re-offense for older offenders like Selby was less than four percent.
At the conclusion of the evidence, the court gave the jury the following instruction:
It is your duty as jurors to determine if the Respondent, Johnny Selby, is or is not a sexually violent predator. In the event of a verdict that the Respondent is a sexually violent predator, you have nothing to do with confinement or treatment.
The jury found Selby to be a sexually violent predator. Selby appeals.
II. Standard of Review
We review constitutional challenges de novo.
In re Detention of
Williams,
III. Merits
Selby argues that chapter 229A is unconstitutional on its face. First, he claims the statute violates due process because it fails to contain a temporal limitation for calculating a predator’s risk of re-offense. Second, he argues that the statute violates *251 equal protection on its face because it requires a standard of proof for commitment different from the standard required to commit similarly situated individuals under Iowa Code chapter' 229 (2003). Finally, Selby argues the court’s instruction stating that jufors had nothing to do with confinement or treatment was in error. We review each of his claims in turn.
A. Due Process
Under the Due Process Clause of the Fourteenth Amendment, no state may “deprive any person of life, liberty, or property, without due process of law.” U.S. Const, amend. XIV, § 1. The Iowa Constitution provides, in similar language, that “no person shall be deprived of life, liberty, or property, without due process of law.” Iowa Const, art. 1, § 9. We consider both the federal and the state due process provisions “to be equal in scope, merit, and purpose.”
In re Detention of Garren,
We engage in a two-step analysis when evaluating substantive due process ■ challenges.
State v. Hernandez-Lopez,
The right Selby asserts, liberty, is widely recognized as fundamental.
E.g., Foucha v. Louisiana,
Selby essentially claims that chapter 229A is not narrowly tailored. He argues that the statute violates due process because it permits commitment through showing that the offender is more likely than not to re-offend at some point within his lifetime. He argues that, in order to pass constitutional muster, the likelihood of re-offense must be within a shorter time period, such as within the immediate future. 1
*252
In order to justify involuntary commitment, a person must not only be mentally ill, but also dangerous.
O’Connor v. Donaldson,
Selby’s claim, however, has more to do with what type of proof should be allowed to show future dangerousness. He argues that evidence of an offender’s lifetime risk allows the State to extrapolate a higher possibility of re-offense. Selby claims that allowing evidence as to an individual’s lifetime risk allows the individual to be confined for acts that may be committed at some time in the indefinite future. As a result, the offender may not be sufficiently dangerous to satisfy due process requirements at the time of commitment. We find Selby’s arguments unconvincing for two reasons: (1) the present tense language of chapter 229A requires that a person be found to be both dangerous and to have a mental abnormality at the time of the proposed commitment and (2) chapter 229A provides for a yearly review of the individual's condition.
Under chapter 229A, a sexually violent predator is
a person who has been convicted of or charged with a sexually violent offense and who suffers from a mental abnormality which makes the person likely to engage in predatory acts constituting sexually violent offenses, if not confined in a secure facility.
*253 Iowa Code § 229A.2(11). A person is “likely to engage in predatory acts of sexual violence” if that person
more likely than not will engage in acts of a sexually violent nature. If a person is not confined at the time that a petition is filed, a person is “likely to engage in predatory acts of sexual violence” only if the person commits a recent overt act.
Id. § 229A.2(4). A mental abnormality is a condition that “predispose[s] that person to commit sexually violent offenses to a degree which would constitute a menace to the health and safety of others.” Id. § 229A.2C5).
Once an individuar is found to be a sexually violent predator, the individual is entitled to an annual review. There is a re-buttable presumption that commitment will continue. Id. § 229A.8(1). If sufficient facts exist, a hearing will be held to determine whether the person “no longér suffers from a mental abnormality which makes the person likely to engage in predatory acts constituting sexually violent offenses if discharged.” Id.
The language of chapter 229A clearly indicates by its use of the present tense that an individual must be both dangerous and possess a mental abnormality that makes the individual likely to engage in sexually violent predatory acts at the time of commitment. For example, a sexually violent person is defined as one who
“suffers
from a mental abnormality which
makes
the person likely to engage” in sexually predatory acts. Iowa Code § 229A.2(11) (emphasis added). A mental abnormality is defined as a “condition
affecting
the emotional or volitional capacity of a
person....” Id.
§ 229A.2(5) (emphasis added). Based on this language, a person must currently be suffering from a mental abnormality that makes the person likely to engage in sexually violent predatory acts. If the person is not confined at the time of the hearing, there must be some “recent overt act.”
Id.
§ 229A.2(4). A recent overt act has been found sufficient for a finding of dangerousness. .
State v. Huss,
In addition, chapter 229A requires an annual examination of the committed individual’s ■ condition. Iowa Code § 229A.8. Commitment is not necessarily indefinite. Rather, it is to last no longer than the person is dangerous or suffers from a mental abnormality which makes the person likely to engage in sexually violent predatory acts.
See Hendricks,
' Because we can construe chapter 229A in a constitutional mariner, there is no reason to declare it facially unconstitutional simply because it does not provide ah explicit time frame for the adjudication of dangerousness. The presence of present tense language and the annual review provision allow 229A to comport with due process requirements.
Selby’s chief complaint is "that testimony as to his lifetime risk of re-offense was allowed at trial. This is an evidentiary *254 problem we cannot decide based upon the record presented to us. Because Selby raised none of the necessary evidentiary objections, we cannot review them.
B. Equal Protection
Selby argues that chapter 229A violates his right to equal protection under the law. Equal protection is guaranteed to all persons pursuant to both the Fourteenth Amendment to the United States Constitution and article I, section 6 of the Iowa Constitution. Both provisions require that similarly situated individuals be treated the same for equal protection purposes.
Williams,
Selby claims that individuals to be committed pursuant to chapter 229A and individuals to be committed pursuant to Iowa Code chapter 229 (2003) are similarly situated but are not given similar treatment under Iowa law. These individuals are similarly situated, he argues, because both chapter 229 and chapter 229A were enacted to confine and treat individuals who are both mentally ill and a danger to the community. The statutes, however, differ in the standard of proof required to show dangerousness. Chapter 229 requires that it be “probable or reasonably to be expected” that a person will be a danger to the community”.
In re Oseing,
Selby takes the argument one step further, contending that chapter 229A permits commitment without any proof that a person presents an imminent threat to the community. This lenient standard, he claims, violates his fundamental right to a fair trial under the Fourteenth Amendment to the United States Constitution and article 1, sections 6, 9, and 10 of the Iowa Constitution. Due to the violation of his fundamental right, Selby urges us to use strict scrutiny to examine the State’s standard of proof for dangerousness under chapter 229A as compared to chapter 229.
Selby’s argument is similar to the claims the supreme court addressed in
Morrow, Garren,
and
Williams.
In
Morrow,
the appellant argued he was being treated differently than other “violent offenders ... with antisocial personality disorder[s] who have served their prison sentences and are due for release.”
Morrow,
In
Garren,
the appellant argued that his right to equal protection was violated by chapter 229A because the statute caused him to be treated differently than other recidivists.
Garren,
The appellant in
Williams
argued that chapter 229A violated his right to equal protection because “it treats mentally ill sexual offender commitments differently
*255
than other mentally ill civil commitments.”
Williams,
Applying the above precedent, we conclude that even before adjudication as sexually violent predators, individuals subject to commitment under chapter 229A are not similarly situated to individuals subject to commitment under chapter 229. In order to be committed under chapter 229A, a person must (1) be convicted or charged with a sexually violent offense; and (2) suffer from a mental abnormality which makes the individual more likely to commit sexually violent predatory acts. Iowa Code § 229A.2(11). Individuals subject to commitment under chapter 229 may be both mentally ill and dangerous, but it is not necessary that they commit a sexually violent offense. Additionally, “their mental illness does not predispose them to commit sexually violent acts.”
Williams,
Furthermore, “classifications of the mentally ill have historically been analyzed under the rational basis test even when individual liberty was at stake.”
Williams,
We must' also conclude that the legislature’s classification of sexually predatory offenders is rationally related to a legitimate government purpose. “ ‘The particularly devastating effects of sexual crimés on victims, and the offender’s need for specialized treatment provide a rational basis for the classification.’ ”
Id.
at 454 (quoting
Morrow,
Even if we were to conclude that the statute was subject to strict scrutiny because it implicates both the right to a fair trial and the right to liberty, we would have to conclude it passes constitutional muster. First, the “more likely than not” standard (the standard that Selby claims permits commitment without any proof that a person presents an imminent threat to the community) is actually a higher standard of proof than the “expected or reasonable probability” standard used in chapter 229.
See Strickland v. Washington,
C. Jury Instruction
The precise issue Selby raises was recently decided in
In re Detention of Crane,
We find nothing erroneous or confusing about the instruction. It is true commitment was a mandatory consequence of the jury’s verdict that [respondent] was a sexually violent predator. The instruction, however, simply told the jurors that they had to determine whether the respondent was a sexually violent predator and instructed them not to concern themselves with the consequences of their decision, which might include treatment and confinement. The instruction accurately stated the law.
[[Image here]]
Jurors are not naive; these jurors knew that if they found [respondent] a sexually violent predator, he would be committed — and probably for a long time. The court’s instruction simply told jurors they should not concern themselves with [respondent’s] subsequent treatment or confinement, but rather, focus upon whether he was a sexually violent predator. The court’s instruction was not erroneous or misleading.
Crane,
AFFIRMED.
Notes
. Though the Iowa courts have not addressed this precise question, we have had numerous occasions to rule on &e constitutionality of other aspects of chapter 229A.
See, e.g., In re Detention of Willis,
. The California Supreme Court used a similar analysis to find the California sexual predator act constitutional.
See Hubbart v. Superior Ct.,
