*1000OPINION

I. INTRODUCTION

The Alaska statute known as the Alaska Sex Offender Registration Act (ASORA) requires persons convicted of sex offenses to register and periodically re-register with the Alaska Department of Corrections, the Alaska State Troopers, or local police, and disclose detailed personal information, some of which is not otherwise public. Most of the disclosed information is publicly disseminated and is published by the state on the internet.1 Does applying ASORA to "John Doe," who committed his crime and was convicted and sentenced before ASORA was enacted, violate the ex post facto clause of the Alaska Constitution? We conclude that it does because ASORA imposes burdens that have the effect of adding punishment beyond what could be imposed when the crime was committed. We therefore hold that ASORA's registration requirement does not apply to persons who committed their crimes before ASORA became effective, and reverse the superior court order granting final judgment in favor of the state and against Doe.

II. FACTS AND PROCEEDINGS

"John Doe" was charged in 1985 with three counts of first-degree sexual abuse of a minor for molesting one of his daughters.2 Doe pleaded no contest to one count of first-degree sexual abuse of a minor, an unclassified felony, and to one count of second-degree sexual abuse of a minor, a class B felony. The superior court accepted his plea and sentenced him to twelve years of imprisonment with four suspended. Doe began serving his sentence in August 1985.

In December 1990 Doe completed serving the unsuspended portion of his sentence less a good-time reduction required by AS 33.20.010(2) and was released to mandatory parole and supervised probation. In September 1991 the Parole Board released Doe from mandatory parole nearly two years early, based on its determination that Doe had participated in rehabilitative counseling and posed little or no threat to the public. In 1995 Doe completed his period of probation.

In May 1994 the Alaska Legislature enact ed the statute known as the Alaska Sex Offender Registration Act (ASORA)3 It be*1001came effective August 10, 1994,4 after Doe was convicted, sentenced, and released from prison, but before he completed his probation. ASORA requires sex offenders to register with the Alaska Department of Corree-tions, the Alaska State Troopers, or local police.5 It requires registrants to disclose their names, addresses, places of employment, date of birth, information about their conviction, all aliases used, driver's license numbers, information about the vehicles they have access to, any identifying physical features, anticipated address changes, and information about any psychological treatment received.6 It authorizes registrants to be photographed and fingerprinted.7 Registrants must periodically re-register and update their disclosures: those convicted of aggravated crimes must re-register quarterly; those not convicted of aggravated crimes must re-register annually.8 A sex offender who changes residences must give notice to the state trooper office or municipal police department closest to his new residence within one working day.9

ASORA requires the Alaska Department of Public Safety to maintain a central registry of sex offenders that contains the information obtained under ASORA.10 ASORA authorizes public access to offenders' names, aliases, dates of birth, addresses, photographs, physical descriptions, motor vehicle information, places of employment, and public information about their convictions and sentences.11 Public access to the information includes a statement as to whether the offender is in compliance with AS 12.63 or cannot be located.12 The Department of Public Safety provides public access to the information by posting it on the internet.13 A photograph of each registrant appears on a webpage under the caption "Registered Sex Offender/Child Kidnapper.14 Each registrant's page also displays the registrant's physical description, home address, employer, work address, and conviction information.15

*1002ASORA's provisions require Doe to register and re-register every three months for the rest of his life.16 But his information has never been publicly released on the state's website. In 1994 Doe (using the pseudonym Rowe) sued state officials in the United States District Court for the District of Alaska challenging ASORA on the grounds it violates the federal prohibition against ex post facto laws, the Fourth Amendment prohibition against unreasonable searches and seizures, his plea bargain contract, and his right to privacy.17 The federal court concluded that Doe established a likelihood of success on his ex post facto and plea agreement violation claims, and found that the balance of hardships tipped in favor of Doe to the extent his registration information would be publicly disseminated.18 It therefore granted a preliminary injunction requiring Doe to register under the act, but prohibiting the state from publicly disclosing the registration information.19 In 1998 the parties filed cross-motions for summary judgment and the district court granted the state's motion.20

On appeal, the United States Court of Appeals for the Ninth Cireuit reversed the state's summary judgment and held that ASORA is an ex post facto law as applied to Doe.21 The Alaska Public Safety Commissioner petitioned for certiorari and the United States Supreme Court reversed the Ninth Circuit's decision after concluding that the statute did not violate the federal ex post facto clause.22 The Court remanded the case to the Ninth Cireuit.23 On remand, the Ninth Cireuit rejected Doe's other federal substantive and procedural due process claims.24 The federal courts did not rule on Doe's state law claims.

In January 2005 Doe sued the state in the superior court, seeking a judgment declaring that ASORA denies him due process in violation of the Alaska Constitution. Doe also requested a temporary restraining order and preliminary and permanent injunctions to prevent the state from requiring him to publicly register. The state opposed Doe's motion for injunctive relief, In August 2005 the superior court denied Doe's motion. It determined that Doe had established the potential for irreparable harm, but had not established a likelihood of success on the merits. It concluded that Doe had not shown that ASORA's registration requirement violated any fundamental right or liberty interest and that requiring Doe to publicly register therefore would not violate his substantive or procedural due process rights.

Anticipating an appeal to this court, the superior court entered a temporary stay under Alaska Civil Rule 62 prohibiting the state from publishing or disseminating Doe's information. The parties agreed no further superior court proceedings were necessary to resolve Doe's claims and stipulated to entry of final judgment. In November 2005 the superior court entered final judgment for the state and against Doe.

Doe appeals.

IH. DISCUSSION

A. Standard of Review

We give de novo review to questions of law, including issues of statutory *1003interpretation.25 In ruling on questions of law, we "adopt the rule which is most persua-give in light of precedent, reason, and policy.26 We apply our independent judgment in determining whether a statute violates the Alaska Constitution.27

B. The Ex Post Facto Clause

1. The parties' contentions

Doe's opening brief argues that compliance with ASORA would impose "harmful and onerous new consequences," violating his right to due process. Because we determined that the essence of his argument is an ex post facto claim, we asked the parties to submit supplemental briefs addressing whether as applied to Doe ASORA violates Alaska's prohibition against ex post facto laws.

Article I, section 15 of the Alaska Constitution, like article I, section 9 of the United States Constitution, provides that "[nJlo ... ex post facto law shall be passed." An ex post facto law is a law "passed after the occurrence of a fact or commission of an act, which retrospectively changes the legal consequences or relations of such fact or deed." 28 These constitutional prohibitions bar the legislature from enacting any law that "punishes as a crime an act previously committed, which was innocent when done; which makes more burdensome the punishment for a crime, after its commission; or which deprives one charged with a crime of any defense available according to law at the time when the act was committed."29 But "[the mere fact that [a statute] alters a convicted felon's cireumstances to his or her disadvantage does not in itself invalidate the statute as ex post facto." 30 In short, the prohibition applies only to penal statutes; the critical question is therefore whether ASORA imposes additional punishment on individuals, like Doe, who committed their crimes before ASORA became effective. Federal courts use a two-part test to determine whether a statute imposes punishment.31 This is the test we will describe in Part IILB.3 and apply in Part III.C. We will refer to this test as the "intent-effects" test or the "multifactor effects" test.

Doe argues that because it "substantially alters" the consequences. attached to the completed crime, ASORA satisfies Alaska's ex post facto clause only if ASORA is applied prospectively, to persons who committed their crimes after August 10, 1994, when ASORA took effect.32

Doe advances two main arguments in support. First, recognizing that the United States Supreme Court held in Smith v. Doe that ASORA does not violate the federal ex post facto clause,33 Doe argues that the Alaska Constitution provides more protection than the Federal Constitution. Doe urges us to read the Alaska ex post facto clause in conjunction with the due process clause34 *1004and article I, section 135 of the Alaska Constitution. He argues that Alaska's due process and ex post facto clauses, unlike the corresponding federal clauses, are aimed at the legislature and that both clauses are intended to "protect individual liberties from retroactive infringement." Doe therefore reasons that we should interpret Alaska's ex post facto clause more broadly than the corresponding federal clause. He alternatively argues that ASORA is an invalid ex post facto law even if Alaska's ex post facto clause is coextensive with its federal counterpart because ASORA is punitive under the federal standard.

The state responds that ASORA is a regulatory law intended to help protect the public by collecting information and making it publicly accessible. It argues that ASORA is not a penal law, and that it was not intended to punish convicted individuals for past acts. The state also contends that because our past decisions discussing the ex post facto clause have interpreted the Alaska prohibition to be the same as the federal prohibition,36 the doctrine of stare decisis obliges us to hold that the Alaska provision is coextensive with the federal provision. The state consequently concludes that because ASORA satisfies the federal ex post facto clause, ASORA also satisfies Alaska's ex post facto clause.37

2. Stare decisis

The state correctly notes that we have relied on federal precedent and analysis in addressing state ex post facto claims in the past.

We concluded in one case that a decision of the Supreme Court addressing an ex post facto challenge to a statute equivalent to the statute then before us "is dispositive of any claim based on the federal constitution, and we see no reason for us to interpret Alaska's constitutional provision differently."38 In another case, we saw "no reason to construe our parallel ex post facto prohibition-article I, section 15-differently from the federal provision." 39 In another, we relied on a Supreme Court opinion in concluding that the challenged statute was compensatory rather than punitive and that it therefore did not violate either the federal or state ex post facto clause.40 And in another case, we stat*1005ed that "[wle construe our state [ex post facto] prohibition no differently than the federal prohibition." 41

In short, having seen "no reason" to do otherwise,42 we construed Alaska's ex post facto prohibition in those cases to be coextensive with the corresponding federal prohibition. We therefore accepted the federal analyses and results. We did so notwithstanding our contemporaneous and repeated recognition that we have the authority and, when necessary, duty to construe the provi-gions of the Alaska Constitution to provide greater protections than those arising out of the identical federal clauses.43

In following federal authority, our ex post facto cases have implicitly reasoned that it was unnecessary in those cases either to deviate from the federal analytical approach or to construe our constitution more protectively.44 We implicitly so reasoned because the federal decisions reached an outcome not inconsistent with the Alaska Constitution. Nonetheless, we have never endorsed federal ex post facto analysis as superseding or limiting our independent consideration of Alaska's ex post facto prohibition.45 Nor have we indicated that federal interpretation of the federal ex post facto prohibition prevents us from reaching a different, and more protective, result under the Alaska Constitution.

Stare decisis therefore has no application here. Today's decision does not overrule or depend on overruling any prior decision of this court, nor does it depart from any past holding of this court. We have never adopted a reading of Alaska's ex post facto prohibition that would, unless overruled, foreclose today's result.46

Nor is today's decision, or the analysis we apply here, inconsistent with the analytical approach we have approved for deciding ex post facto claims under the Alaska Constitution. Our reliance on the multifactor effects test is consistent with our past use of federal *1006law in resolving state ex post facto claims.47 And in applying that test here we also reach a result consistent with what the federal standards appear to have been before 2008, when the Supreme Court decided Smith.48

That the Supreme Court, after considering the same factors and same statute that we consider today, held in Smith v. Doe that there was no ex post facto violation may seem to raise several questions. First, why doesn't Smith's holding control this case as a matter of stare decisis? Second, why doesn't Smith's discussion of the multifactor effects test control our analysis in applying the same factors? Third, even if Smith's discussion of those factors is not directly controlling, how can we rationally disagree with it?

As to the first question, Smith's holding is not stare decisis here because Doe's claims are based on the Alaska Constitution, whereas Smith was based exclusively on the Federal Constitution49 Smith did not apply state law or decide state law issues.

As to the second question, how we apply the multifactor effects test in deciding an ex post facto claim under the Alaska Constitution is not governed by how the federal courts independently apply the same test under the Federal Constitution, as long as our interpretation is at least as protective as the federal interpretation.50 What we have said in our ex post facto cases cannot be read as prospectively limiting the protections of the Alaska Constitution to what federal courts might later say the corresponding federal clauses provide. Nor could we have done so.51

Finally, the Supreme Court's discussion in Smith certainly informs our analysis here. But it does not and cannot preempt our independent analysis or dictate the result we reach. Our interpretation of a clause in the Alaska Constitution is not limited by the Supreme Court's interpretation of the corresponding federal clause.52 As the Supreme Court has recognized,

[i]f a state court chooses merely to rely on federal precedents as it would on the pree-edents of all other jurisdictions, then it need only make clear by a plain statement in its judgment or opinion that the federal cases are being used only for the purpose of guidance, and do not themselves compel the result that the court has reached.[53]

*1007Consequently, the results of the federal opinions do not control our independent analysis when, in interpreting the Alaska Constitution, we look for guidance to either federal precedent or the analytical framework applied by federal courts. Our adoption of the analytical approach approved by the federal courts likewise does not mean that we are bound by how the Supreme Court applied that approach in Smith. The question before us is whether applying ASORA to Doe violates Alaska's ex post facto provision. As to that question, Alaska retains its sovereign authority.

3. Our choice of analytical approach

We begin our analysis by identifying the appropriate analytical framework. In Smith v. Doe, the Supreme Court considered the identical issue under the Federal Constitution and applied the multifactor "intent-effects" test derived from the Court's prior decisions.54 Under this test, a court first determines whether the legislature intended to impose punishment; if punishment was the intent, the court's inquiry ends.55 But if the court concludes that the legislature intended a non-punitive regulatory scheme, the court next analyzes the effects of the statute under a number of factors to determine whether the statute is nonetheless punitive in effect.56 Our court has never adopted this test, but the Alaska Court of Appeals applied it in considering and rejecting an ex post facto challenge to ASORA in Patterson v. State.57

The intent-effects test provides an appropriate analytical framework here. Although a multifactor test is potentially susceptible to different conclusions, the availability of reported decisions applying that test helps inform its application in new cases.

Our conclusion that it is appropriate to apply the federal test to our state law inquiry in this case is consistent with our independent consideration of each of the test's seven factors, because we are here both construing the protections of our constitution and reviewing an enactment of our legislature. Therefore, even though we choose to consider the same factors the federal courts use to distinguish between civil remedies and erimi-nal penalties,58 we give independent consideration to these factors in applying the Alaska Constitution.

C. ASORA Is Punitive for Purposes of the Alaska Ex Post Facto Clause.

The intent-effects test would usually first require us to consider whether the Alaska Legislature, when it enacted ASORA, intended to enact a regulatory scheme that is civil and non-punitive.59 If the purpose was not punishment but regulation, the test would next require us to determine whether the effects of regulation are so punitive that we must nonetheless conclude that ASORA imposes punishment.60

It is not necessary to address the first step of the test-whether the legislature intended ASORA to punish convicted sex offenders-because the second part of the test-whether ASORA's effects are punitive-resolves the dispute before us. Assuming without deciding that the legislature intended ASORA to be non-punitive,61 we therefore focus on the *1008statute's effects to determine whether they are punitive.62

In assessing a statute's effects, the Supreme Court indicated in Ward the seven factors it listed in 1968 in Kennedy v. Mendoza-Martines "provide some guidance":63

(1) "(whether the sanction involves an affirmative disability or restraint";

(2) "whether it has historically been regarded as a punishment";

(8) "whether it comes into play only on a finding of scienter";

(4) "whether its operation will promote the traditional aims of pumshmen’o—retmbu— tion and deterrence";

(5) "whether the behavior to which it applies is already a erime";

(6) "whether an alternative purpose to which it may rationally be connected is assignable for it"; and

(7) "whether it appears excessive in relation to the alternative purpose assigned." [64]

The Supreme Court has not explained the relative weight to be afforded each factor. But the Court has recognized that the factors "often point in differing directions" and that no one factor is determinative.65 Determining whether a statute is punitive necessarily involves the weighing of relatively subjective factors.

We address each of the factors in turn.

1. Affirmative disability or restraint

We first ask "[wlhether the sanction involves an affirmative disability or restraint."66 The state argues that ASORA involves neither because it imposes no physical restraint, has obligations less harsh than occupational debarment-which the Supreme Court has held to be non-punitive 67-and, in the Supreme Court's words, "restrains [no] *1009activities sex offenders may pursue but leaves them free to change jobs or residences."68

But even though the statute imposes no physical restraints, we agree with Justice Stevens's dissenting comments in Smith that ASORA "imposel[s] significant affirmative obligations and a severe stigma on every person to whom [it] appllies]."69 First, ASORA compels affirmative post-discharge conduct (mandating registration, re-registration, disclosure of public and private information, and updating of that information) under threat of prosecution.70 The duties are significant and intrusive, because they compel offenders to contact law enforcement agencies and disclose information, some of which is otherwise private, most of it for public dissemination.71 Furthermore, the time periods associated with ASORA are intrusive.72 Sex offenders convicted of an aggravated sex offense73 or two or more sex offenses must re-register quarterly for the rest of their lives; all other offenders must re-register annually for fifteen years.74 All sex offenders who change residences must notify the state trooper office or municipal police department closest to their new residences within one working day.75 As we stated in Doe v. State, Department of Public Safety (Doe A), "ASORA thus treats offenders not much differently than the state treats probationers and parolees subject to continued state supervision."76

Second, we agree with the conclusion of Justice Ginsburg, also dissenting in Smith, that ASORA "exposes registrants, through aggressive public notification of their crimes, to profound humiliation and community-wide ostracism."77 In the decision reversed in Smith, the Ninth Cireuit observed that "(bly posting [registrants'] names, addresses, and employer addresses on the internet, the Act subjects [registrants] to community obloquy and scorn that damage *1010them personally and professionally.78 The Ninth Circuit observed that the practical ef-feet of this dissemination is that it leaves open the possibility that the registrant will be denied employment and housing opportunities as a result of community hostility.79 As Justice Souter noted in concurring in Smith, "there is significant evidence of onerous practical effects of being listed on a sex offender registry."80 Outside Alaska, there have been reports of incidents of suicide by and vigilantism against offenders on state registries.81

We also disagree with the Supreme Court's conclusion in Smith that the obligations ASORA imposes are less harsh than the occupational debarment which the Court has held to be non-punitive.82 The Supreme Court has upheld the constitutionality of post-conduct professional sanctions that included the prohibition of further participation in the banking industry83 and revocation of medical licenses.84 A comparable bar for sex offenders who pose a risk to children might be employment in places frequented by children. But the practical effects here can predictably extend to all employment opportunities as well as to all other non-employment aspects of life, including housing opportunities. There are published reports that offenders are sometimes subjected to protests and group actions designed to force them out of their jobs and homes.85 We agree that "[the practical effect of such un*1011restricted dissemination could make it impossible for the offender to find housing or employment."86

The state argues, however, that the negative effects that Doe emphasizes (negative impacts on employment and housing opportunities) will exist even if Doe is not subject to ASORA because those consequences result not from registration and dissemination of information, but from the conviction itself. Moreover, the state asserts that there is no evidence that Alaskans have directed any wrath at convicted sex offenders and notes that the sex offender registry website warns viewers about using registry information to commit a criminal act.87

Neither of these arguments is persuasive. ASORA requires release of information that is in part not otherwise public or readily available. Moreover, the regulations authorize dissemination of most ASORA registration information "for any purpose, to any person."88 Taken in conjunction with the Alaska Public Records Act,89 ASORA's treatment of this information, confirmed by the regulations, seems to require that the information be publicly available. By federal law, it is disseminated statewide, indeed worldwide, on the state's website.90 There is a significant distinction between retaining public paper records of a conviction in state file drawers and posting the same information on a state-sponsored website; this posting has not merely improved public access but has broadly disseminated the registrant's information, some of which is not in the written public record of the conviction. As the Alaska Court of Appeals noted, "ASORA does provide for dissemination of substantial personal and biographical information about a sex offender that is not otherwise readily available from a single governmental source."91 'We also recognized in Doe A that several sex offenders had stated that they had lost their jobs, been forced to move from their residences, and received threats of violence following establishment of the registry, even though the facts of their convictions had always been a matter of public record.92 We therefore conclude that the harmful effects of ASORA stem not just from the conviction but from the registration, disclosure, and dissemination provisions.

We are also unpersuaded by the state's assertion that there is insufficient evidence to establish that harmful effects have actually occurred in Alaska. Doe's affidavit contains excerpts from affidavits submitted in the federal court. The excerpts recite instances of registrants losing employment, having difficulty finding housing and employment, and *1012moving out of the marital home due to fear of the effects public dissemination would have on their families. Similarly, the Ninth Circuit, when addressing Doe's earlier ex post facto challenge to ASORA, noted that the record before that court contained evidence that a sex offender suffered community hostility and damage to his business after printouts of the Alaska sex offender registration website were publicly distributed and posted on bulletin boards.93

2. Sanctions that have historically been considered punishment

We next determine "whether [the statute's effects have] historically been regarded as a punishment."94 ASORA does not expressly impose sanctions that have been historically considered punishment.95 Because registration acts such as ASORA are "of fairly recent origin," courts addressing this issue have determined that there is no historical equivalent to these registration acts.96 Some courts have instead considered whether the acts are analogous to the historical punishment of shaming; these courts have concluded that they are not.97 But the dissemination provision at least resembles the punishment of shaming98 and the registration and disclosure provisions "are comparable to conditions of supervised release or parole."99 And these provisions have effects like those resulting from punishment. The fact that ASORA's registration reporting provisions are comparable to supervised release or parole supports a conclusion that ASORA is punitive. -

3. Finding of scienter

Third, we consider "whether [the statute] comes into play only on a finding of scien-ter."100 The obligations of ASORA are not imposed solely upon the finding of sceienter.101 ASORA also applies to strict liability offenses, such as statutory rape, that the law deems sufficiently harmful to effectively assume scienter.102 But even though ASORA applies to a few strict liability offenses, it overwhelmingly applies to offenses that re*1013quire a finding of scienter for conviction.103 The few exceptions do not imply a non-punitive effect, given the assumption of scienter for those exceptions and the fact that a reasonable-mistake-of-age defense is allowed in a charge of statutory rape.104 This factor therefore receives little weight in our analy-sig; it weakly implies a punitive effect.

4. The traditional aims of punishment M

We next ask "whether [the statute's] operation will promote the traditional aims of punishment-retribution and deterrence."105 Although in State v. Chaney we identified four objectives of criminal sentencing-rehabilitation, isolation, deterrence of defendant and others, and reinforcement of societal norms 106-the Mendoza-Moartines test focuses on retribution and deterrence.107 The state argues that the registration and dissemination provisions are not retributive and that any deterrent effects of registration and dissemination are only incidental to the provisions' regulatory function.

But ASORA's application to a broad spectrum of crimes regardless of their inherent or comparative seriousness 108 refutes the state's argument and suggests that such retributive and deterrent effects are not merely incidental to the statute's regulatory purpose. Every person convicted of a sex offense must provide the same information, and the state publishes that information in *1014the same manner, whether the person was convicted of a class A misdemeanor or an unclassified felony. ASORA's only differentiation is in the frequency and duration of a person's duty to register and digclose.109 But at any given moment the registration list does not distinguish those individuals the state considers to pose a high risk to society from those it views as posing a low risk. ASORA determines who must register based not on a particularized determination of the risk the person poses to society but rather on the criminal statute the person was convicted of violating.

In Kansas v. Hendricks the Supreme Court determined that the Kansas Sexually Violent Predator Act is not retributive because "it does not affix culpability for prior criminal conduct." 110 That act is not triggered by a criminal conviction, but rather by criminal conduct; it applies to individuals charged with sexually violent offenses but who may be absolved of criminal responsibilitty.111 The Supreme Court there stated that "[aln absence of the necessary eriminal responsibility suggests that the State is not seeking retribution for a past misdeed." 112 But as we discuss in Part III.C.5, ASORA applies only to those convicted of specified offenses.113

Moreover, in Smith v. Doe the Supreme Court noted that the state had conceded that ASORA "might deter future erimes," 114 an effect that would be punitive. Although the state has made no similar concession in this appeal, it is significant that the state there admitted that the same statute on the same facts currently before us could have deterrent effects. The state argues here that, in the Supreme Court's words, it "would severely undermine the Government's ability to engage in effective regulation" 115 to determine that a law is punitive because it also deters. We assume for sake of discussion that a statute limiting registration requirements and public dissemination to the extent necessary to protect the public could have a deterrent effect that would be merely incidental to its non-punitive purpose. But ASORA's registration and unlimited public dissemination requirements provide a deterrent and retributive effect that goes beyond any non-punitive purpose and that essentially serves the traditional goals of punishment.

5. Application only to criminal behavior

Under the fifth factor we consider "whether the behavior to which [the statute] applies is already a crime."116 The fact that a statute applies only to behavior that is already, and exclusively, criminal supports a conclusion that its effects are punitive.117 When analyzing ASORA the Supreme Court asserted in Smith that this factor was "of little weight in this case."118 The Court there stated that conviction is "a necessary beginning point, for recidivism is the statutory concern."119 But if recidivism, ie., new sexual misconduct, were the only concern, the statute would apply not just to convicted sex offenders but to other individuals who may pose a threat to society even if they were not convicted. See, for example, the Washington registration act, upheld by the Ninth Circuit; it includes sex offenders not found guilty-including those incompetent to stand trial, those found not guilty by reason of insanity, and those committed as sexual psychopaths or sexually violent predators-as well as those who are conviected.120 The Utah regis*1015tration act, also constitutionally upheld, includes those found not guilty on the ground of mental incapacity.121

As the state concedes, ASORA applies only to those "convicted" of specified offenses.122 Defendants charged with sex offenses but who plead out to non-sex offenses such as coercion or simple assault do not have to register even though they may have engaged in the same conduct as individuals who do have to register.123 Likewise, even convicted defendants whose convictions are overturned for reasons other than insufficiency of evidence of guilt do not have to register despite having engaged in the same conduct.124 An adult who commits sexual abuse of a minor in the first degree by engaging in sexual penetration with a person under thirteen years of age,125 but whose conviction is overturned due to an illegal search, does not have to register. Finally, ASORA does not require registration for those charged with sex offenses but sequitted, even though they may have engaged in the same conduct as convict, ed sex offenders and might even be found civilly liable under a lesser standard of proof.

It is true that ASORA applies to individuals who either enter a plea of or are found "guilty but mentally ill." 126 But we do not read this inclusion to make the seope of ASORA the same as that of the Washington and Utah registration acts previously discussed. Because including this class of offenders again looks to guilt, applying ASORA to those found guilty but mentally ill does not demonstrate any non-punitive effect.

In other words, ASORA fundamentally and invariably requires a judgment of guilt based on either a plea or proof under the eriminal standard. It is therefore the determination of guilt of a sex offense beyond a reasonable doubt (or per a knowing plea), not merely the fact of the conduct and potential for recidivism, that triggers the registration requirement. Because it is the criminal conviction, and only the eriminal conviction, that triggers obligations under ASORA, we conclude that this factor supports the conclusion that ASORA is punitive in effect.127

6. Advancing a non-punitive interest

We next ask whether, in the words of the Supreme Court, "an alternative purpose to which [the statute] may rationally be connected is assignable for it."128 We translate this as an inquiry whether ASORA advances a legitimate, regulatory purpose. ASORA can rationally be viewed as advancing a non-punitive purpose.129 When it enacted ASO-RA the legislature found that:

(1) sex offenders pose a high risk of reof-fending after release from custody;

(2) protecting the public from sex offenders is a primary governmental interest;

(3) the privacy interests of persons convicted of sex offenses are less important than the government's interest in public safety; and

(4) the release of certain information about sex offenders to public agencies and the *1016general public will assist in protecting the public safety. [130]

The Ninth Cireuit stated that the state's non-punitive interest in public safety "unquestionably provides support, indeed, the principal support, for the view that the statute is not punitive for Ex Post Facto Clause purposes."131 The Supreme Court also stated that ASORA's rational connection to a non-punitive purpose was a "[mJost significant" factor in its determination that ASORA is non-punitive in effect.132 We likewise conclude that ASORA advances a non-punitive interest.

7. Closeness of connection of means to the state's interest in public safety

Finally, we determine "whether [ASORA] appears excessive in relation to the alternative purpose assigned."133 In analyzing this factor the Ninth Circuit addressed the scope of individuals subject to ASORA and the breadth of its dissemination provision; it determined that ASORA makes "information as to all sex offenders ... available without any restriction and without any regard to whether the individual poses any future risk."134 The Ninth Cireuit consequently concluded that ASORA's "non-punitive purpose, while of unquestioned importance, does not serve to render a statute that is so broad and sweeping non-punitive."135

The Supreme Court also addressed the scope and magnitude of ASORA's registration requirements and its dissemination provision, but concluded that ASORA is not excessive in relation to the state's interest in public safety.136 In so deciding it determined that "[the Ex Post Facto Clause does not preclude a State from making reasonable categorical judgments that conviction of specified crimes should entail particular regulatory consequences,"137 and that the duration of ASORA's reporting requirements and what the Court called ASORA's "passive" notification system are not so excessive as to be effectively penal.138

The Court stated that the excessiveness inquiry is "not an exercise in determining whether the legislature has made the best choice possible to address the problem it seeks to remedy. The question is whether the regulatory means chosen are reasonable in light of the nonpunitive objective." 139

As the legislature found when enacting ASORA, "protecting the public from sex offenders is a primary governmental interest." 140 The state certainly has a valid interest in addressing not just the egregious and highly publicized crimes that gave rise to the Megan's Law movement,141 but also other crimes of which the risk of repetition and grave harm is sufficiently predictable to justify the protections afforded by ASORA. But in the context of our ex post facto ingui-ry, we have an obligation to determine whether the means chosen to carry out legitimate purposes are excessive, le., not close enough to be classified as non-penal.

*1017We use "means" here to include the scope of the statute and the obligations it imposes on those subject to it and what the state can or must do in enforcing it.

It is significant that ASORA's seope is broad; it encompasses a wide array of crimes that vary greatly in severity.142 Moreover, ASORA provides no mechanism by which a registered sex offender can petition the state or a court for relief from the obligations of continued registration and disclosure.143 "Offenders cannot shorten their registration or notification period, even on the clearest determination of rehabilitation or conclusive proof of physical '144 Doe successfully completed a treatment program and was granted early release from mandatory parole. A superior court granted him legal custody of his minor daughter based on its determination that he was successfully rehabilitated and posed "a very low risk of re-offending." 145 Despite this evidence of rehabilitation, ASORA requires Doe to register quarterly and requires the state to publicly disseminate his personal information for the rest of his life.146

Under ex post facto analysis we further conclude that the statute's chosen means are excessive in relation to the statute's purpose because the statute is also underinelusive. As we discussed in Part III.C.5, ASORA only applies to those convicted of specified offenses.147 It therefore excludes from its requirements individuals who may have committed the same acts and may pose threats to the public but who avoided conviction by pleading to a lesser charge or whose convictions were overturned. We do not mean to suggest that making the statute more inclusive would necessarily resolve ex post facto issues or that such changes would otherwise be constitutionally unobjectionable, but we point to this feature to illustrate that ASORA has a punitive effect.

ASORA also imposes obligations that, for ex post facto purposes, are excessive in relation to the state's legitimate public safety interest. -It is significant that the registration and re-registration requirements are demanding and intrusive148 and are of long duration.149

Finally, the provisions authorizing or requiring the state to disseminate the information are sweeping. ASORA is much broader than the Connecticut statute that authorizes courts to order the state to restrict dissemination if the court finds that dissemination is not required for public safety and that publication of the information would likely reveal the identity of the victim.150 ASORA is much closer to the Kansas statute struck down on ex post facto grounds by the Kansas Supreme Court because of its "unrestricted public access ... [that] goes beyond that necessary to promote public safety."151

We are not balancing the rights of sex offenders against the rights of their vice-tims.*1018152 Rather, we are determining for ex post facto purposes whether the means chosen to protect the public have consequences to sex offenders that significantly go beyond the state's valid interest in public safety, and exclude individuals who may pose equivalent threats to public safety. Some sex offender registration statutes employ means that have been held to relate rationally and closely enough to the state's interest in public safety. For example, the Second Circuit concluded that the notification policy adopted by the Connecticut Office of Adult Probation was "not excessive in relation to its purpose of enhancing public awareness and helping to prevent the recovering offender from harmful relapses."153 Connecticut allows certain sex offenders convicted between October 1, 1988 and June 80, 1999 to "petition the court to order the Department of Public Safety to restrict the dissemination of the registration information to law enforeement purposes only and to not make such information available for public access."154 Connecticut also provides certain sex offenders the possibility of avoiding registration and dissemination upon a judicial determination that registration or public dissemination is not required for public safety.155

"A statute is not deemed punitive simply because it lacks a close or perfect fit with the nonpunitive aims it seeks to advance." 156 Although the non-punitive aims are undeniably legitimate and important, ASORA's registration and dissemination provisions have consequences to sex offenders that go beyond the state's interest in public safety; we must therefore conclude that the Alaska statute is excessive in relation to the state's interest in public safety.

8. ASORA's effect

Summing up the effects under the seven factors, we conclude that ASORA's effects are punitive, and convincingly outweigh the statute's non-punitive purposes and effects. We recognize that several of the factors seem closely related, and that discussion of one may overlap discussion of another. Nonetheless it is not the mere number of factors that leads us to our conclusion, but our assessment of those factors and their relative weight. Six of those factors lead us to disagree, respectfully but firmly, with the Supreme Court's analysis and its ultimate conclusion that ASORA is not penal.157 Our decision is consistent with what we consider to be the compelling comments of dissenting justices in Smith158 and with the majority of the Ninth Cireuit Court of Appeals panel that, before reversal, discerned an ex post facto violation under federal law.159

*1019Because ASORA compels (under threat of conviction) intrusive affirmative conduct, because this conduct is equivalent to that required by criminal judgments, because ASO-RA makes the disclosed information public and requires its broad dissemination without limitation, because ASORA applies only to those convicted of crime, and because ASO-RA neither meaningfully distinguishes between classes of sex offenses on the basis of risk nor gives offenders any opportunity to demonstrate their lack of risk, ASORA's effects are punitive. We therefore conclude that the statute violates Alaska's ex post facto clause.160

IV. CONCLUSION

Because ASORA's registration, disclosure, and dissemination provisions violate the protection against ex post facto laws afforded by the Alaska Constitution as it applies to defendants who committed their crimes before the legislature enacted ASORA, we hold that AS 12.63.100(8) cannot be applied to Doe. We consequently REVERSE the final judgment for the state, and REMAND for entry of judgment for Doe.

dissenting.

I disagree with the court's conclusion that ASORA violates the ex post facto clause of the Alaska Constitution. The court maintains that its "reliance on the multifactor effects test is consistent with our past use of federal law in resolving state ex post facto claims." But our past decisions have firmly established a practice of interpreting the Alaska ex post facto clause "no differently" than its federal counterpart.1 The court now purportedly applies that federal test to the facts of this case: "[the intent-effects test provides an appropriate analytical framework here." But the court's decision directly conflicts with the United States Supreme Court's application of the same test to the same statute.2 As we have concluded in the past, this case presents "no reason for us to interpret Alaska's constitutional provision differently." 3

The court defends its expansion of Alaska's constitutional protections against ex post fac-to litigation as "consistent with what the federal standards appear to have been before 2003, when the Supreme Court decided Smith." But the Smith Court announced no intention to depart from the standards that it had previously created or to alter the Mendoza-Martines multifactor effects test. The Smith Court reasoned that its "examination of [ASORA's] effects leads to the determination that [Doe] cannot show, much less by the clearest proof, that the effects of the law negate Alaska's intention to establish a civil regulatory scheme."4 Despite this court's implication that the United States Supreme Court misapplied the Federal Ex Post Facto Clause, today's decision actually broadens the protections of Alaska's ex post facto clause beyond that of the Federal Constitution. Thus, the court must justify its departure from our established practice of interpreting the Alaska and federal ex post facto clauses as coextensive. Today's decision, however, fails to do so.

*1020Of course, "we have the authority and, when necessary, duty to construe the provisions of the Alaska Constitution to provide greater protections than those arising out of the identical federal clauses." For example, we have devised our own sliding-seale test to implement "Alaska's more stringent equal protection standard,"5 which we have held "protects Alaskans' right to non-discriminatory treatment more robustly than does the federal equal protection clause."6 We have held that the state constitution entitles Alaskans to a jury trial where the Federal Constitution does not.7 And we have interpreted the Alaska Constitution's mandate that "[nljo person shall be put in jeopardy twice for the same offense" 8 to extend beyond the Federal Constitution's double jeopardy protections.9 But where we have expanded Alaskans' constitutional protections beyond federally required minimums, we have recognized a "duty to move forward in those areas of constitutional progress which we view as necessary to the development of a civilized way of life in Alaska.10

We have never recognized broader protections under the Alaska Constitution's ex post facto clause as compared to the Federal Constitution's.11 In Danks v. State, we examined an ex post facto challenge to a habitual offender statute.12 As in this case, the United States Supreme Court had rejected a challenge to a similar statute under the federal clause.13 Accordingly, we held that the Supreme Court decision disposed of Danks's federal claim, and we saw "no reason for us to interpret Alaska's constitutional provision differently." 14 In State v. Anthony, we rejected challenges under the state and federal ex post facto clauses to a law that deprived certain felons of receiving the annual permanent fund dividend.15 Our analysis did not differentiate between the two clauses and noted the parties' agreement "that the ex post facto prohibition of the Alaska Constitution is the same as that of the United States Constitution." 16

As in this case, State v. Creekpaum17 involved a sex offender. Creekpaum was charged with sexual assault over five years after the alleged assault took place. At the time that Creekpaum allegedly committed his offense, a five-year limitations period applied. But the legislature subsequently extended that period. In rejecting Creekp-aum's challenge to the new limitations period under the state and federal ex post facto clauses, we relied almost exclusively on United States Supreme Court precedents in similar cases and once again declined "to construe our parallel ex post facto prohibition-article I, section 15-differently from the federal provision." 18

Finally, in State v. Coon, we rejected a claim that our adoption of new evidentiary rules for the admission of scientific evidence violated "federal and state constitutional pro*1021hibitions on ex post facto legislation."19 Our decision in Coon followed from an analysis of federal precedent and our explanation that "Iwle construe our state prohibition no differently than the federal prohibition." 20

These decisions leave no doubt that our practice of treating the state and federal ex post facto clauses coextensively is settled precedent. The court's decision today, recognizing broader protections under the Alaska Constitution, casts a pall of uncertainty upon our earlier decisions. The court nevertheless declares that its decision "does not overrule or depend on overruling any prior decision of this court, nor does it depart from any past holding of this court." This assertion ignores the plain language of our previous holdings and alters the doctrine of stare decisis beyond recognition.

We have explained that "a prior decision may be abandoned because of 'changed conditions' if 'related principles of law have so far developed as to have left the old rule no more than a remnant of abandoned doctrine, [or] facts have so changed[,] or come to be seen so differently, as to have robbed the old rule of significant application." 21 Perhaps one could view the ongoing development of federal case law, and the United States Supreme Court's Smith decision in particular, as a "changed condition." But the court makes no attempt to frame its decision in such a manner. Instead, the court fails to recognize that today's decision is indeed "inconsistent with the analytical approach we have approved for deciding ex post facto claims under the Alaska Constitution."

Because the court has decided to overrule our settled practice of construing the Alaska Constitution's ex post facto clause "no differently than the federal prohibition," 22 it must meet the higher threshold raised by the principle of stare decisis. In my opinion, that threshold has not been met. Stare decisis demands that we adhere to past precedent unless "we are clearly convinced the rule was originally erroneous or is no longer sound because of changed conditions, and that more good than harm would result from a departure from precedent." 23 Assuming arguer-do that the Supreme Court's decision in Smith upsets our reliance on Federal Ex Post Facto Clause jurisprudence, I remain unconvineed that departing from our precedents to invalidate ASORA would result in more good than harm. Alaska is not alone in passing legislation that responds to this public safety threat.24 In 1994 Congress passed the Jacob Wetterling Crimes Against Children and Sexually Violent Offender Registration Act,25 which conditions federal funding to assist law enforcement on established guidelines for state sex offender registration programs. Alaska's sex offender registration program forms one small part of a nationwide comprehensive regulatory program.

Nothing in the court's analysis gives reason to depart from our established practice of interpreting Alaska's ex post facto clause to mirror the protections of the United States Constitution. Our adherence to this practice has not proceeded automatically, and it has reflected our regard for the judgments of the United States Supreme Court in this area. Accordingly, I respectfully dissent.
