Lifetime sex offender registration statutes are common across the states,1 and several state supreme courts have reached conflicting results in analyzing the constitutionality of these requirements as applied to juveniles.2 In State ex rel. D.D.,3 the Louisiana Supreme Court joined the list of state high courts that have upheld such a statute, addressing the constitutionality of Louisiana’s registration statute under the Sixth4 and Eighth5 Amendments.6 In resolving D.D.’s Eighth Amendment challenge, the court failed to consider the developmental differences between juvenile and adult offenders at the threshold stage of determining whether the statute was punitive. In doing so, the court narrowed Supreme Court proportionality precedents regarding juveniles, potentially foreshadowing weakened protections for juvenile defendants.
In July 2022, T.W. reported to a youth-camp counselor that she had been raped several months earlier by her then-boyfriend, D.D.7 D.D. was then adjudicated delinquent for second-degree rape.8 He was fourteen years old when he committed the offense, and sixteen years old at the time of the adjudication.9 In accordance with Louisiana’s sex offender registration law, which applies to juveniles at or over the age of fourteen who have been adjudicated delinquent for specific sex offenses,10 D.D. was informed that he would have to register as a sex offender upon his release from confinement.11 D.D. challenged the registration requirement’s constitutionality under the Sixth and Eighth Amendments in a pre-adjudication motion, which the juvenile court denied.12
D.D. appealed, asserting various trial errors and repeating his constitutional challenges.13 The Louisiana First Circuit Court of Appeal affirmed both the adjudication and the denial of constitutional claims.14 D.D. then appealed to the Louisiana Supreme Court,15 raising the same arguments: that “his adjudication [was] not supported by sufficient evidence,” that the juvenile court erred in its treatment of certain witnesses, and that the denial of his Sixth and Eighth Amendment claims was an error.16
The Louisiana Supreme Court affirmed.17 Writing for the majority, then-Justice Crain18 quickly rejected the trial errors D.D. asserted, devoting most of the opinion to the constitutional claims.19 Justice Crain first rejected D.D.’s Eighth Amendment claim.20 His analysis focused on the threshold question for Eighth Amendment analysis: whether the registration requirement qualified as “punishment” and was thus subject to the Cruel and Unusual Punishments Clause.21 Only if the requirement was “punishment” would the court proceed to the “cruel and unusual” analysis,22 which asks whether a punishment’s severity is disproportionate to the offender’s culpability.23
Justice Crain then applied the test governing whether a scheme is punitive or merely regulatory.24 First, he assessed the legislative purpose behind the registration requirement, concluding that the legislature intended it as a regulatory regime to facilitate law enforcement’s efforts to protect the community from sex offenders, but not to punish them.25 He then assessed whether the requirement’s punitive effects outweighed the legislature’s intent to deem it civil,26 applying the factors from the U.S. Supreme Court case Kennedy v. Mendoza-Martinez.27 He considered whether the statute’s effects: “(1) have historically been regarded as punishment, (2) impose an affirmative disability or restraint, (3) promote the traditional aims of punishment, (4) have a rational connection to a nonpunitive purpose, and (5) are not excessive with respect to this purpose.”28
Applying these factors, Justice Crain rejected D.D.’s argument that the registration requirement was punitive.29 In deciding that the first three factors weighed in the state’s favor, Justice Crain relied on Smith v. Doe,30 a 2003 Supreme Court case that applied the Mendoza-Martinez factors to hold Alaska’s sex offender registration scheme nonpunitive.31 Regarding the first factor (whether the requirement has been historically considered punishment), Justice Crain recognized that registration may in effect humiliate a juvenile, but distinguished this “collateral consequence” of the Act’s legitimate purpose — public safety — from historical examples of humiliation, whose purpose was to punish.32 Similarly, he “agree[d] with Smith” that the second and third factors weighed in favor of the requirement being nonpunitive, concluding that it “d[id] not impose an affirmative disability or restraint” (the second factor) and that any “deterrence effect [wa]s not sufficient to render the Act punitive” (the third).33 He determined that the fourth and fifth factors (both regarding the requirement’s nonpunitive purpose) were the most important, and that the registration requirement, given its legitimate public purpose, was nonpunitive.34
Finally, Justice Crain addressed D.D.’s argument that the registration requirement violated the Eighth Amendment in its application to juveniles “by impermissibly extending the juvenile court’s jurisdiction into the offender’s adult life” and thus conflicting with the juvenile system’s rehabilitative goals.35 Justice Crain recognized the Supreme Court precedents of Miller v. Alabama36 and Graham v. Florida,37 which held that juveniles’ developmental differences diminished their culpability and thus impacted the Eighth Amendment analysis in the context of life incarceration without parole.38 However, he concluded those precedents did not apply here, reasoning that, unlike life without parole, this scheme was not punishment (based on his Mendoza-Martinez determination), nor did it “subject [juveniles] to a lifetime of incarceration” and related consequences (given that the statute exempted juveniles from community notification and provided an opportunity for review).39
Justice Crain went on to reject D.D.’s other argument that imposing the registration requirement violated his Sixth Amendment right to trial by jury.40 Justice Crain started by summarizing the “fundamental differences between the adult and juvenile [justice] systems,” noting that trial by jury is not constitutionally required for the latter due to its “‘non-criminal’ nature.”41 He then held that the registration requirement had no effect on these distinctions, thus making trial by jury unnecessary for juveniles.42
Chief Justice Weimer concurred to distinguish the majority’s decision from his dissent in State v. I.C.S.,43 which also involved aggravated rape by a juvenile.44 In that case, the defendants were under fourteen (the statutorily specified minimum age of registration for juvenile offenders)45 when they committed the offense, but pled guilty after turning eighteen.46 There, Chief Justice Weimer disagreed with the majority’s decision to require registration under the statute’s provisions for adult offenders, arguing that the legislature had not intended to require registration where the defendant committed the offense before turning fourteen.47 In contrast, because D.D. committed the offense after turning fourteen, Chief Justice Weimer explained that he fell within the ambit of the juvenile registration requirement.48
Justice Hughes dissented, asserting that, especially for juveniles, “[r]egistration is not punishment like gaming is not gambling.”49
Justice Guidry also dissented. Emphasizing the Eighth Amendment’s “proportionality precept,” he first determined that the registration requirement constituted punishment as applied to juveniles.50 Although acknowledging that the legislature may not have intended the registration requirement to be punitive, he disagreed with the majority’s application of the Mendoza-Martinez factors and would have held that the requirement’s punitive effects outweighed its possibly benign purposes.51 He described registration, even if reviewable after twenty-five years, as “a constant cloud hovering” that would “define[] a minor’s adult life well before it has a chance to start.”52 He also would have held that this onerous punishment was disproportionate to juvenile offenders’ culpability and thus cruel and unusual, citing Miller and Graham for the proposition that juvenile offenders have diminished culpability.53
The court failed to give sufficient weight to D.D.’s youth in its application of the Mendoza-Martinez factors. Although the United States Supreme Court has identified three developmental differences that diminish juveniles’ culpability,54 the D.D. court largely ignored these precedents in its analysis, instead relying on a case that did not involve juveniles.55 This was wrong; both the U.S. Supreme Court and other state courts have applied these precedents across various criminal proceedings. In particular, recognizing these differences would have supported the opposite conclusion on the second and fifth Mendoza-Martinez factors.
The U.S. Supreme Court has declared that “children are different” for constitutional purposes.56 While it is true that both Miller and Graham involved sentences of life without parole,57 the Supreme Court in these cases also made broader statements about the developmental differences between juveniles and adults. First, juveniles have an “underdeveloped sense of responsibility,” leading them to behave more recklessly.58 Second, they “are more vulnerable . . . to negative influences.”59 Finally, their characters are less “well formed,” increasing their likelihood of rehabilitation.60 In both cases, the Court determined that these developmental differences made a certain form of punishment — life without parole for nonhomicide offenders in Graham, and mandatory life without parole in Miller — disproportionate in relation to juvenile offenders’ culpability, and thus cruel and unusual.61
Despite these precedents treating juvenile and adult offenders differently, the D.D. court’s Mendoza-Martinez analysis did not give sufficient weight to D.D.’s youth. D.D. challenged the registration statute’s constitutionality as applied specifically to juvenile offenders.62 Although the court addressed D.D.’s argument that registration was more humiliating for juveniles, it relied upon Smith for its application of the other Mendoza-Martinez factors.63 This reliance was misplaced; although both cases involved a sex offender registration statute, the petitioners in Smith did not make any constitutional arguments about the special status of juvenile offenders. Rather, they challenged the statute as applied to offenders who had committed the assault before the statute’s enactment.64 Therefore, whether the court agreed with Smith’s reasoning was not a relevant question, because Smith did not present an appropriate analogy. Nor did the D.D. court mention Miller and Graham in its application of the factors.65 Instead, it held in its Eighth Amendment analysis that these precedents were “not applicable” to the present case.66
Miller and Graham should be read to support the conclusion that a practice may constitute punishment as applied to juveniles, even if nonpunitive as applied to adults; therefore, the D.D. court was wrong to cabin these precedents to the second step of the Eighth Amendment inquiry — whether a punishment is excessive. Both the “is it punishment” and “is it excessive” inquiries involve a form of proportionality analysis: The former, through the fifth factor, requires weighing the severity of the punishment against the legislature’s civil intent (in factor five), while the latter requires weighing the severity of the punishment against the offender’s culpability. Although Miller and Graham addressed only the latter inquiry, they recognized that juveniles’ developmental differences affected both parts of the weighing: Not only are children less culpable for their offenses, but they also may experience the same punishment more severely.67 Thus, if an offender’s age is relevant to assessing the severity of a statute intended to be punitive, it should also be relevant to assessing the severity of a statute intended to be civil.
The D.D. court’s failure to recognize these developmental differences outside the facts of Miller and Graham contradicts how the Supreme Court itself has applied them. Nowhere in these cases did the Court suggest that these three differences were relevant only to categorical proportionality analysis.68 Indeed, in J.D.B. v. North Carolina,69 the Supreme Court cited Graham wholly outside the Eighth Amendment context to conclude that age was a relevant characteristic in determining whether a minor had been held in custody for Miranda purposes.70 Since J.D.B., state courts have read the Miller line of cases broadly, applying the principle that “children are different” to a range of criminal proceedings.71 Most relevant to D.D.’s case, in evaluating a similar registration statute, the Colorado Supreme Court cited J.D.B. to apply Miller and Graham to the specific question of whether a practice is punitive under the Eighth Amendment.72 By choosing to read Miller and Graham narrowly, the D.D. court undermined the precedential value of these landmark decisions.
Applying these principles to D.D.’s case would have supported a conclusion that the registration requirement was punishment as applied to juveniles, in line with Justice Guidry’s dissent.73 This is apparent in the court’s determination of the second Mendoza-Martinez factor — the “affirmative disability or restraint” inquiry — which requires assessing “how the effects of the [statute] are felt by those subject to it.”74 The court’s analysis contradicted extensive social science research demonstrating the negative impact of sex offender registration on juvenile development. For example, in a report by Human Rights Watch, over half of the juvenile offenders interviewed described being “denied access to or experienc[ing] severe interruptions in their . . . education” due to registration — a consequence unique to school-age offenders.75 Furthermore, juveniles are particularly vulnerable to the stigmatizing effects of registration, which may lead to “profound damage to a child’s development and self-esteem.”76 This aligns with the Supreme Court’s observation that juveniles’ unique susceptibility to outside influences can cause “psychological damage.”77
Similarly, in evaluating whether the statute was excessive in relation to its stated purpose of protecting the public from repeat offenders,78 the court failed to consider research that juvenile sex offenders are less likely to recidivate than their adult counterparts.79 When they do recidivate, it is typically within five years of the offense,80 underscoring Graham’s recognition that juveniles’ character traits are transitory and likely to change.81 This research weakens the force of the lifetime-registration requirement’s nonpunitive public safety rationale as applied to juveniles, who are less likely to be lifetime offenders. Thus, the statute’s punitive effect is excessive in relation to that weaker purpose, bringing it closer to punishment for juveniles. These factors exemplify how the court’s failure to consider registration’s differential impacts on juveniles and adults led it to the wrong conclusion.
Ultimately, the D.D. court’s reasoning artificially constrains the Eighth Amendment’s protections for juveniles.82 By failing to discuss Graham and Miller during the threshold inquiry, a court can avoid acknowledging the particular harshness of lifetime sex offender registration for juveniles, so long as it first determines that such registration is not punishment. Moreover, this reasoning can easily be applied outside of the sex offender registration context, leading to diminished protections for juveniles across a range of state statutes.83 D.D. is particularly noteworthy given the recent trend of federal courts narrowing Eighth Amendment protections for juveniles.84 In this context, state high courts ought to play an increasingly important role in securing juveniles’ rights, particularly in open Eighth Amendment questions.
