    Before ROVNER, WOOD, and ST. EVE, Circuit Judges.
    ROVNER, Circuit Judge. Sex offender registration and noti-
    fication laws have a unique place at the intersection of crimi-
    nal and civil law. These civil laws impose cumbersome and
    often lifelong burdens on former criminal perpetrators, many
    of whom have finished all forms of imprisonment and post-
    imprisonment supervision. For this reason, they are fre-
    quently challenged as unconstitutional. In this case, the
    2                                                   No. 19-2523
    plaintiffs have challenged Indiana’s Sex Offender Registra-
    tion Act (SORA) as it applies to offenders who have relocated
    to Indiana from other states after the enactment of SORA, and
    who are forced to register under the law, but would not have
    been required to do so had they committed their crimes as
    residents of Indiana prior to the enactment of the relevant
    portions of SORA and maintained citizenship there. The dis-
    trict court found the registration requirements to be unconsti-
    tutional, and we uphold the district court’s finding that this
    application of SORA violates the plaintiffs’ right to travel.
    I.
    Although sex offender registries had been around for
    some time prior, they proliferated in the early 1990’s due to a
    few high profile and highly publicized heinous crimes against
    children by repeat sex offenders. We can assume that more
    widespread access to the internet in the 1990’s also contrib-
    uted to the proliferations of these laws. For the first time, an-
    yone with an internet connection could access the information
    in these registries from their homes with a few mouse clicks
    and find out the location of convicted sex offenders in their
    communities. In 1994, Indiana enacted its own version of a sex
    offender registry, SORA, also called “Zachary’s Law,” after a
    10-year-old boy who was tragically sexually assaulted and
    murdered by a neighbor with a previous criminal conviction
    for sexual assault of a child. 1994 Ind. P.L. 11 § 7 (codified as
    Indiana Code §§ 5-2-12-1 through 5-2-12-13) (current version
    at 
    Ind. Code §§ 11-8-8-1
     through 11-8-8-23).
    Around the same time, in the federal arena, Congress was
    enacting sex offender registration and notification laws, cul-
    minating in 2006 with the federal Sex Offender Registration
    and Notification Act (SORNA), 
    34 U.S.C.A. § 20901
     et. seq.,
    No. 19-2523                                                              3
    which requires states to maintain public registries with spec-
    ified sex offender information. Indiana has periodically
    amended its SORA to remain in compliance with changing
    requirements of the federal SORNA, and, according to Indi-
    ana’s brief, to target those most likely to recidivate. In 1996,
    the Indiana General Assembly revised SORA to require regis-
    tration by one convicted elsewhere of a state offense that is
    substantially equivalent to an Indiana offense that triggers a
    duty to register. 1996 Ind. P.L. 33 § 2; see also 2001 Ind. P.L. 238
    § 4 (making substantial equivalency provision retrospective).1
    And, most relevantly, in 2006, the legislature amended SORA
    to apply the statute’s requirements to any “person who is re-
    quired to register as a sex offender in any jurisdiction.” 2006
    P.L. 140 § 5(b)(1) (codified at 
    Ind. Code §§ 11-8-8-4
    .5(b)(1), 11-
    8-8-5(b)(1)).
    Those amendments have greatly expanded both the list of
    persons required to register and the information those regis-
    trants are required to provide. The current SORA require-
    ments are many. A person required to register under SORA
    must report in person at least once annually to the local sher-
    iff’s office in the county of residence, and if the registrant is
    employed or attends school in a different county, the regis-
    trant must report to the sheriff’s office in each of those coun-
    ties as well. Sexual offenders who have committed one of nine
    specified offenses are considered to be “sexually violent pred-
    ators” and must report to the local sheriff’s office every ninety
    days. Ind. Code. § 11-8-8-14(b). A person who is homeless or

    Ind. Code §§ 11-8-8-4
    .5(a)(22), 11-8-8-5(a)(24). As of July 1, 2020, the “substantial
    equivalency” provision has been moved to Ind. Code 1-1-2-4(b) and made
    more generally applicable across Indiana’s Code.

    lives in transitional or temporary housing must appear in per-
    son at least once every seven days. 
    Id.
     at § 11-8-8-12(b)(2).
    Registration requires more than simply appearing at the
    sheriff’s office. The person registering must be photographed
    and provide information including their name, date of birth,
    race, height, weight, hair color, eye color, identifying features
    such as scars and tattoos, social security number, driver’s
    license or state identification card number, vehicle
    description and license plate number of any vehicle the
    registrant might operate regularly, principal address, name
    and address of any employer or educational institution, any
    electronic mail addresses, any instant messaging user names,
    any social networking website user name and “[a]ny other
    information required by the [Department of Corrections
    (DOC)].” 
    Ind. Code § 11-8-8-8
    (a).2 Most of this information is
    published on the public registry, although some of the
    information (such as an individual’s e-mail address) is not
    available to the public. If any of this information changes, the
    registrant must go in person to the sheriff’s office, within
    seventy-two hours, to report it. Ind. Code. § 11-8-8-8(c). That
    means, for example, if a registrant gets a Pinterest account,
    that person must report the new account, in person, at the
    local sheriff’s office, within seventy-two hours. Convicted sex
    offenders are required to maintain a valid driver’s license or
    state identification card and are prohibited from seeking a
    name change. Ind. Code. §§ 11-8-8-15(b), 16.
    In addition to all of these requirements, a sexually violent
    predator must inform law enforcement of any absences away

    once every ninety days if the offender is a “sexually violent
    predator.” 
    Ind. Code § 11-8-8-13
    (a). As of March 16, 2018,
    there were close to 10,000 persons required to register as sex
    or violent offenders in Indiana. R. 100-2 at 9.
    After cataloguing the burdens that we have just enumer-
    ated, the Indiana Supreme Court concluded that “the Act im-
    poses significant affirmative obligations and a severe stigma
    on every person to whom it applies. … [and the] duties im-
    posed on offenders are significant and intrusive.” Wallace v.
    State, 
    905 N.E.2d 371
    , 379 (Ind. 2009). As a result, the Indiana
    Supreme Court concluded that the Act had the “effect of add-
    ing punishment beyond that which could have been imposed
    when his crime was committed,” and therefore the State could
    not impose the requirements of SORA on anyone whose of-
    fense predated the enactment of that statute.

    so, it held, would violate the ex post facto clause of the Indiana
    Constitution.

    person to register if the offense occurred prior to SORA—
    provided that person remains a resident of Indiana.
    This case is before us now, however, because, despite the
    Wallace decision, persons with pre-SORA convictions who re-
    locate to Indiana from another state where registration was
    required or relocate from Indiana to another state requiring
    registration and then back again, must register in Indiana,
    even if Indiana would not have required them to register had
    they committed their offenses in Indiana and never left.
    We must pause here, before getting to the State’s reasons
    for requiring these registrations, in order to untangle a Gor-
    dian knot in this case. The State has argued in its briefs that
    there are two situations in which the DOC decides that a per-
    son is required to register upon moving to Indiana.6 Those cir-
    cumstances are as follows:
    (1) The substantial equivalency requirement: If an individual
    relocates to Indiana after the offense of which that individual
    was convicted, or its out-of-state-equivalent, became a regis-
    trable offense, the DOC requires that individual to register
    based on its determination that, at the time that the individual
    relocated to Indiana, he was “on notice” that the offense re-
    quires registration. (R. 100-1 at 24–25, R. 100-2 at 15–16). Indi-
    ana requires the person to register whether or not that person
    was obligated to register in the state from which that person
    came.
    6 The DOC and local county sheriff’s offices jointly maintain SORA and
    the DOC makes a final determination as to who is required to register and
    for how long each offender must register. Ind. Code, §§ 11-8-2-12.4, 11-8-
    2-13(b), 36-2-13-5.5.
    No. 19-2523                                                             7
    (2) The other jurisdiction requirement: If the individual is re-
    quired to register in another jurisdiction and relocates to In-
    diana after July 1, 2006, the DOC requires the individual to
    register pursuant to Indiana Code § 11-8-8-5(b)(1), which de-
    fines a “sex or violent offender” to include an individual “re-
    quired to register as a sex or violent offender in any jurisdic-
    tion.” (R. 100-1 at 24-25, 39; R. 100-2 at 16–17).7 Of course, one
    can be required to register in another state as a result of one’s
    employment or school enrollment in that state, even if he does
    not live there. E.g., 730 ILCS 150/3(a-5). Thus, the State points
    out that “[a] lifelong Indiana resident who would otherwise
    fall within the Wallace rule will be required to register if he
    works in another state that requires him to register;” State Br.
    at 5. But that particular application of the other jurisdiction
    requirement is not at issue here: So far as the briefing reveals,
    none of the six plaintiffs was subject to registration in another
    jurisdiction as a result of work, study, or some conduct apart
    from residence in that jurisdiction.
    In its fact section generally, and in the description of each
    plaintiff, and throughout its brief, the State maintains that all
    of the plaintiffs must register because of both of the statutory
    requirements we have just identified. State’s Brief at 22, 23, 24,
    25. As an example, the State asserts in its brief that Gary
    Snider must register because of both the substantial equiva-
    lency requirement (the crime he committed in Michigan in
    1988 is substantially equivalent to an Indiana registrable of-
    fense), and because of the other jurisdiction requirement (he
    7 July 1, 2006 is the date that the Indiana General Assembly amended
    SORA to apply the statute’s requirements to any “person who is required
    to register as a sex offender in any jurisdiction.” See 2006 Ind. P.L. 140
    § 5(b)(1) (codified at 
    Ind. Code §§ 11-8-8-4
    .5(b)(1), 11-8-8-5(b)(1)).
    8                                                     No. 19-2523
    was required to register in Michigan). State’s Brief at 23–24.
    Snider committed his crime in 1988, long before Indiana’s
    SORA was enacted, and moved to Indiana in 2003—three
    years before Indiana enacted the other jurisdiction require-
    ment of SORA. Nevertheless, the State’s brief asserts that he
    was required to register under both provisions. This is but one
    of several conflicting assertations that the State makes about
    Snider. It also presents two others. In its representative depo-
    sition pursuant to Federal Rule of Civil Procedure 30(b)(6),
    the State asserted that because Snider moved to Indiana be-
    fore the other jurisdiction requirement was added to SORA,
    he would only have to register on the basis of the substantial
    equivalency requirement. R. 100-1 at 25. And at oral argu-
    ment, the State asserted that Indiana’s ex post facto clause
    would not allow the state to require registration from some-
    one whose only basis for that registration was a pre-SORA of-
    fense that is the substantial equivalent of an Indiana offense
    made registrable by SORA. Oral argument at 8:57–12:00. To
    put this all together, the State’s briefs assert that Snider had to
    register for both reasons. At the 30(b)(6) deposition the State
    maintained that Snider would not have to register under the
    other jurisdiction prong because he arrived in Indiana before
    that requirement was added. And at oral argument, the State
    asserted that Snider could not be required to register because
    of the substantial equivalency requirement alone because of
    the Supreme Court decision in Wallace. We do not what else
    to call this other than “a mess.”
    Part of this confusion stems from the odd manner in which
    Indiana describes the operation of SORA. It refers to the stat-
    utory requirements of SORA as one aspect of the law, and
    then distinguishes the statutory law from the rulings by the
    Indiana Supreme Court invalidating certain applications of
    No. 19-2523                                                     9
    those laws. This, however, is not how we ordinarily describe
    operative state law. For example, in 2003, the U.S. Supreme
    Court declared unconstitutional the Texas statute making it a
    crime for two persons of the same sex to engage in certain in-
    timate sexual conduct. Lawrence v. Texas, 
    539 U.S. 558
    , 
    123 S. Ct. 2472
     (2003). Despite this ruling, the Texas statute that
    makes it a crime if a person “engages in deviate sexual inter-
    course with another individual of the same sex” remains on
    the books in Texas to this day. See Tx. Penal Code § 21.06. Yet
    no one ought to write a brief which describes same sex behav-
    ior as illegal in Texas under the statute but allowed by the Su-
    preme Court’s interpretation of the Constitution. Legisla-
    tively enacted laws, modified by case law, together as a whole
    become the law of the land and we do not continue to refer to
    the statutory law of Texas separately from the law of Texas as
    limited, clarified, or modified by the judiciary.
    From this we can make several brief conclusions before
    continuing on with the facts, with the promise for more anal-
    ysis later. First, the decision in Wallace prevents the State from
    requiring new (or returning) residents to Indiana to register
    under the substantial equivalency prong alone, if their crime
    occurred before the date that SORA would have required reg-
    istration for the substantially equivalent crime in Indiana. The
    State concedes this in its brief, at oral argument, and in a sup-
    plemental filing. See State’s brief at 21 (“[A]n offender who
    committed his registrable offense prior to the adoption of
    SORA and who would not have any registration obligations
    but for SORA cannot be required to register; under Wallace,
    the marginal effects of such an application would be puni-
    tive.); id. at 38 (“[A] pre-SORA offender who moves to Indiana
    from a State where he was not required to register will also
    not be required to register in Indiana.”); State’s Reply Brief at
    10                                                           No. 19-2523
    6 (“[W]hether SORA can be applied to an offender whose
    criminal conduct predates the statute turns on whether he has
    already been required to register[;] … these decisions would
    thus permit applying SORA if he were a lifelong Hoosier
    whose out-of-state travel triggered another State’s registra-
    tion requirement, while they would prohibit applying SORA
    if he were a recent resident whose prior State did not require
    registration.”) (emphasis removed); Oral argument at 3:28–
    3:44 and 8:57–12:00 (asserting that if a pre-SORA offender
    moved to Indiana from a state where he was not required to
    register, he would not be required to register in Indiana even
    if his crime was a substantially equivalent offense); State’s
    Rule 28(j) letter dated April 13, 2020 at 1–2 (“Under the Indi-
    ana Supreme Court’s decisions, Indiana’s Ex Post Facto
    Clause prohibits applying SORA to someone whose offense
    predates SORA and who is not required to register in another
    State.”)
    Second, as we will explain later, Wallace also prevents the
    State from requiring registration under the other jurisdiction
    prong alone if the new (or returning) resident relocated to In-
    diana before 2006, when the other jurisdiction requirement
    was added to SORA. With this in mind, we can continue with
    the remaining facts.
    The plaintiffs maintain that five of them have been re-
    quired to register as sex offenders in Indiana because of both
    the substantial equivalency determination and the other juris-
    diction requirement, and that Snider had to register solely be-
    cause of the substantial equivalency requirement.8 As we
    8 Hope has to register because of the “registrable offense” part of the sub-
    stantial equivalency/registrable offense requirement. Because he
    No. 19-2523                                                               11
    noted above, we cannot understand why the State maintains
    that each plaintiff had to register for both reasons under the
    statute, but at the same time oddly concedes that it cannot re-
    quire a pre-SORA offender to register on the basis of the sub-
    stantial equivalency requirement alone.
    As we shall see, ultimately these distinctions about why
    an offender was required to register are not relevant to the
    outcome of this case. Instead, our outcome depends on the
    fact that two people who committed the same crime at the
    same time have different registration requirements depend-
    ing on their history of residency in Indiana. Nevertheless, be-
    cause the State has created much confusion with its bifurca-
    tion of the “statutory law” and the “constitutional law,” we
    will make clear that we are proceeding with our analysis of
    the case with the understanding that the State cannot apply
    the substantial equivalency registration requirement to any
    plaintiff who committed his offense before that offense be-
    came registrable in Indiana.9 As a matter of Indiana law, it
    may only require registration of pre-SORA offenders by those
    who were required to register in another jurisdiction.10 This
    committed his crime in Indiana it need not be compared to Indiana crime
    to establish equivalence.
    9 The first iteration of SORA became effective on March 2, 1994. All of the
    plaintiffs committed their offenses prior to this date, with the exception of
    Standish, who committed his offense on February 1, 1995. But the offense
    Standish committed did not become a registrable offense in Indiana until
    the statute was amended years later.
    10 We conclude, as we discuss further below, that this creates an over-
    looked problem with requiring registration from Snider and Bash, both of
    whom arrived in Indiana prior to the addition of the other jurisdiction re-
    quirement. We address this problem later.
    12                                                    No. 19-2523
    in turn is what gives rise to the plaintiffs’ right-to-travel claim:
    having relocated from other states that required them to reg-
    ister, they are burdened with an obligation to register in Indi-
    ana that would not be imposed on a similarly-situated of-
    fender who has lived in Indiana continuously since commit-
    ting his offense.
    Before we turn to the individual circumstances of the
    plaintiffs, we can describe the generalized facts that apply to
    all of them. As a historical matter, it appears that all six of the
    plaintiffs were required to register in Indiana based on a
    determination by the DOC and local sheriff’s departments
    that they had committed a registrable offense or the out-of-
    state equivalent to such an offense and that they had been
    required to register in another jurisdiction. Although they
    committed their offenses before SORA was amended to
    require registration on these grounds, the State deemed the
    amendments applicable to the plaintiffs because they had
    relocated (or returned) to Indiana after SORA was revised to
    include these registration requirements. Indiana would not
    have required them to register on these grounds had they
    been living in the State at the time they committed their
    offenses and remained there continuously thereafter. The
    State now concedes that, as a matter of Indiana law (including
    the Indiana Supreme Court’s decision in Wallace), the
    plaintiffs can only be compelled to register based on the other
    jurisdiction requirement—that is, because they were required
    to register in another state. (We will discuss below why this
    theory is problematic as it relates to Snider and Bash, who
    moved to Indiana before the other jurisdiction requirement
    was enacted). All of the plaintiffs committed their crimes a
    long time ago—between approximately twenty-five to thirty-
    five years ago. All have fully served their sentences resulting
    No. 19-2523                                                                13
    from their sex-offense conviction.11 All qualify as an “offender
    against children,” and as a “serious sex offender.” All have
    lifelong labels, which are prominently displayed on the
    publicly available registry. Snider is now in his mid-sixties
    and committed his crime thirty-two years ago. Hope was
    nineteen when he committed his crime—twenty-four years
    ago. Mr. Bash was in his early teens or even younger when,
    about thirty-five years ago, in the mid-1980’s, he committed
    his crime. Standish, Rice, and Rush, like Snider, are all over
    fifty years old, and have families that include children (and in
    at least one case, grandchildren) of their own.
    Brian Hope pled guilty to child molestation in 1996 for a
    crime that occurred in 1993 (twenty-seven years ago). He
    completed his probation in 2000 and has not been under any
    form of supervised release since then. In 2004 he left Indiana
    and relocated to California and then Texas, where he was re-
    quired to register as a sex offender.12 He returned to Indiana
    in 2013 to help care for a sick grandfather. Hope is the only
    plaintiff who committed his offense in Indiana before the

    from the restraints of parole or probation. See Jones v. Helms,

    Cir. 2003).
    12 There are conflicting explanations in the briefs about why Hope was
    required to register in Texas. Hope claimed that it was because he was
    required to register in Indiana. The State asserts that he was required to
    register in Texas because his offense in Indiana was “substantially similar”
    to a Texas offense and thus required registration under Texas Penal Code
    Ann. § 21.11. In any event, the relevant facts here are that Hope is now
    required to register in Indiana because he had been required to register in
    Texas. For purposes of the application of Indiana’s SORA, the reasons for
    the initial registration elsewhere are not relevant.

    enactment of SORA, left, and then returned after SORA. Upon
    his return, the state required him to register for the remainder
    of his life as an “offender against children” because he was
    required to register in Texas. 
    Ind. Code § 11-8-8-5
    (b)(1). Be-
    cause he is homeless, every seven days he must walk one to
    two miles each way to the Sheriff’s office and wait in line to
    register. The whole process—including travel, wait time, and
    registration—can take several hours. Hope cannot live within
    1,000 feet of a park, daycare, or certain other facilities. On at
    least one occasion, he had to relocate from a homeless shelter
    because it was located within 800 feet of a park. It is uncon-
    troverted that had he remained a resident of Indiana, Wallace
    would have relieved him of any obligation to register. He un-
    successfully appealed the determination that he must do so to
    both the Marion County Sheriff’s Department and the DOC.
    A Michigan jury convicted Gary Snider in 1994 of criminal
    sexual conduct in the first degree. Snider continues to deny
    liability for his offense but stated in his affidavit that it was
    his recollection that, at trial, the victim did not have a precise
    memory of when the offense took place but testified that it
    occurred in the first half of 1988 (thirty-two years ago). R. 100-
    4 at 1. He married his wife while in prison, and the day he
    completed his prison term in 2003, he moved to Indiana
    where his wife lived and worked—three years before the In-
    diana legislature added the other jurisdiction requirement to
    SORA. Prior to the decision in Wallace, Snider was registered
    as a sex offender. In 2006, he moved away from his wife be-
    cause their home was located within 1,000 feet of a daycare.
    In 2010, the Huntington County Sheriff’s Department in-
    formed him that he was no longer required to register because
    of the decision in Wallace (his offense predated the enactment
    of that statute). In 2016, the DOC told him that Wallace no
    No. 19-2523                                                   15
    longer applied and he would have to register as both a “sex-
    ually violent predator” and an “offender against children”
    every ninety days for the remainder of his life. He cannot en-
    ter school property to see any of his five grandchildren or
    great grandchildren perform in school activities.
    In 1996, Joseph Standish pleaded no contest to attempted
    criminal sexual conduct which occurred in Michigan in 1995
    (25 years ago). He completed probation in 2001, and, when his
    wife received a job in Indiana in 2013, he moved with her. In-
    itially DOC did not require him to register but changed course
    in 2016. He is now required to register as an “offender against
    children” and a “sexually violent predator,” and must do so
    at least every ninety days. Mr. Standish cannot watch his chil-
    dren participate in school activities and cannot take them to
    and from school.
    In 1989, an Illinois court convicted and sentenced Patrick
    Rice for an aggravated criminal sexual assault that took place
    that year (31 years ago). Lacking a home or resources after his
    release from prison in 2017, he relocated to Indiana to live
    with his sister. Although Illinois required that Rice register
    only for ten years, Indiana requires him to register for life
    because he qualifies as a “sexually violent predator.” The
    registration process for Madison County, where he first
    settled, required him to pay an initial registration fee of fifty
    dollars and to make multiple trips within a seventy-two-hour
    period. Shortly after he was released from prison and arrived
    in Indiana, he had to make eight to ten trips to the local
    sheriff’s office—to register initially, to provide a copy of his
    newly obtained government identification, then his newly
    obtained social security card, his new telephone number, a
    new e-mail address, and a Facebook account. He must repeat
    16                                                   No. 19-2523
    the process any time he changes any of the listed information.
    Without reliable transportation, he has to rely on other people
    and their schedules to take him the six or seven miles to
    register, and he must often wait an hour or more before
    registering. A few months after registering in Madison
    County, he had to repeat the process in Delaware County
    after moving there with a partner. As an “offender against
    children” and a “sexually violent predator,” he must repeat
    this process every ninety days for the remainder of his life.
    In 1990, Adam Bash pleaded guilty but mentally ill to the
    Kentucky crime of rape in the first degree and sodomy in the
    first degree for crimes committed in the mid-1980s, when he
    was somewhere between a pre-teen and an early teen. In 1998,
    he completed his prison sentence—which he spent mostly in
    psychiatric or medical facilities—without any required parole
    or probation. Upon his release, he relocated to Ohio, where he
    was required to register, before settling in Indiana around
    1999 or 2000, about six years before SORA’s other jurisdiction
    requirement was enacted. Nevertheless, he is required to reg-
    ister in Indiana annually as an “offender against children.”
    Bash subsists on social security benefits, and because of his
    conviction, does not qualify for any public housing assistance.
    His housing options also have been limited by the prohibition
    on living within 800 feet of certain facilities. All of this makes
    it difficult for him to pay the fifty-dollar registration fee and
    the five-dollar change-of-address fee, the latter of which, de-
    spite its name, has been imposed when he registered a change
    in car and haircut. Because of his precarious financial situa-
    tion, he sometimes has to go on a payment plan. Bash has full
    legal custody of his young son, but he cannot enter school
    property for his activities or for parent-teacher conferences.
    No. 19-2523                                                     17
    In 1992, Scott Rush was charged and convicted in a Florida
    state court of sexual battery of a child less than twelve years
    old. He completed his sentence in 1995, and his probation in
    2005. In 2017 his employer closed its Florida office and offered
    him a position in Indiana, which required him to relocate.
    Rush qualifies as a sexually violent predator and an offender
    against children and must register every ninety days (or
    sooner if his information changes). He lives approximately six
    miles from the sheriff’s office where he must register, and the
    process generally takes more than an hour, but he must take
    an entire day off of work to complete the process, as his job is
    not flexible enough to allow him to come and go. Mr. Rush
    has been affected most significantly from the prohibition on
    entering school property, as his daughter has a learning disa-
    bility, and every two to three months he must miss the school
    meeting convened to discuss her needs and individualized
    educational program.
    Hope and Snider filed suit for declaratory and injunctive
    relief against the Commissioner of the DOC, their respective
    county prosecutors’ offices and respective county sheriffs
    challenging the constitutionality of the statute, later adding
    Standish as a plaintiff. The district court entered a preliminary
    injunction on April 6, 2017, enjoining Indiana’s enforcement
    of SORA against all three plaintiffs. A few months after Hope
    and Snider filed their complaint, Rice, Bash, and Rush filed a
    similar complaint. By agreement, the cases were consolidated,
    and the preliminary injunction was extended to the new
    plaintiffs. On July 9, 2019, the district court issued its Entry on
    Cross-Motions for Summary Judgment holding that “SORA
    violates Plaintiffs’ fundamental right to travel, Plaintiffs’ right
    to equal protection of the laws, and the Constitution’s prohi-
    bition against retroactive punishment.” R. 118 at 36.
    18                                                  No. 19-2523
    Indiana’s rule that those moving into the state
    must register while similarly situated residents
    do not have to register violates Plaintiffs’ funda-
    mental right to travel and guarantee to equal
    protection of the laws. The application of
    SORA’s requirements retroactively also violates
    the Constitution’s prohibition against retroac-
    tive punishment. That means the registration re-
    quirements as applied here cannot stand.
    
    Id. at 2
    . The State defendants appealed. We now affirm the
    district court’s finding that application of SORA to this class
    of offenders violates their fundamental right to travel in that
    it treats them less favorably than Indiana citizens with com-
    parable criminal histories who lived in Indiana before the
    other jurisdiction requirement of SORA was enacted.
    II.
    We review the district court’s summary judgment deci-
    sion de novo. E.g., Johnson v. Enhanced Recovery Co., 
    961 F.3d 975
    , 982 (7th Cir. 2020). Because we conclude that the State’s
    application of SORA to the plaintiffs impermissibly interferes
    with their right to travel, we do not reach the district court’s
    alternative finding that it also violates their rights under the
    ex post facto clause of the United States Constitution.
    Although all six of the plaintiffs were convicted of sex of-
    fenses before SORA would have required them to register for
    those offenses, Indiana nonetheless requires each of them to
    register based on subsequent amendments to SORA. As we
    have noted, throughout this litigation, Indiana has repre-
    sented that each of the plaintiffs is required to register on ei-
    ther of two independent grounds: (1) he relocated to Indiana
    No. 19-2523                                                    19
    after his offense (or its out-of-state equivalent) became a reg-
    istrable offense under SORA (the substantial equivalency re-
    quirement); or (2) he was required to register in his previous
    state of residence (the other jurisdiction requirement). But the
    State’s appellate briefs defend the plaintiffs’ registration obli-
    gation solely on the basis of the other jurisdiction require-
    ment, and as noted the State’s lawyer conceded at oral argu-
    ment that Indiana’s ex post facto clause precludes application
    of the substantial equivalency requirement to the plaintiffs. It
    is therefore clear that Indiana places no reliance on the sub-
    stantial equivalency requirement as a basis for demanding
    that the plaintiffs register as sex offenders.
    As to the plaintiffs’ claim that Indiana has interfered with
    their right to travel by requiring them to register, the State’s
    legal theory is that SORA does not make the sort of distinction
    between newer and more longstanding citizens that the per-
    tinent line of Supreme Court right-to-travel cases forbids.
    What triggers SORA’s application to the plaintiffs, the State
    emphasizes, is not the timing of their arrival in Indiana but
    rather the fact that they were subject to a registration require-
    ment in another jurisdiction. Thus, someone relocating to In-
    diana today will have no obligation to register there if he was
    under no such obligation in his former state of residence,
    whereas a lifelong Indiana citizen will incur an obligation to
    register in Indiana if he becomes obligated to register in an-
    other state by virtue of taking a job or enrolling in school in
    that state. Our dissenting colleague makes essentially the
    same point: Application of the other jurisdiction requirement
    turns not on whether or when an offender moved to Indiana
    from another state but rather on another state’s imposition of
    a duty to register, period. Indiana is not intentionally treating
    newly arrived offenders differently and thus burdening their
    20                                                    No. 19-2523
    right to travel; at most, the burden that an offender incurs on
    relocating to Indiana is incidental to his interstate travel.
    Whatever superficial appeal this line of reasoning might
    have in the abstract, it does not defeat the plaintiff’s right-to-
    travel claim. Indiana is not contending that the plaintiffs must
    register because they committed a registrable offense or its
    equivalent, nor is Indiana relying on some other aspect of the
    plaintiffs’ conduct in another state signaling a danger that
    warrants the plaintiffs’ registration in Indiana. It instead relies
    solely on the fact that another state, in the exercise of its inde-
    pendent judgment, required each of the plaintiffs to register,
    although Indiana itself would not have required the plaintiffs
    to do so in the first instance. Because Indiana is placing exclu-
    sive reliance upon another state’s decision to require an of-
    fender to register, it is necessarily (if implicitly) using an of-
    fender’s travel as the trigger for its own registration require-
    ment. It is true that there are two types of travel implicated by
    the other jurisdiction requirement: relocation to Indiana from
    another state and commuting from Indiana to another state
    for work or study. All six of the plaintiffs have relocated to
    Indiana, and it is that particular type of travel, and its unique
    place in the Supreme Court’s right-to-travel jurisprudence,
    that is at issue here. Indiana commuters who have picked up
    registration obligations elsewhere may or may not have their
    own constitutional claim—theirs is a different form of travel
    for constitutional purposes—but no such claim has been
    raised or briefed in this case. For the plaintiffs, all of whom
    committed sex offenses before those offenses became registra-
    ble in Indiana, it is the fact of their subsequent relocation that
    gives rise to a duty to register in Indiana; had they lived in
    Indiana at the time of their offenses and never left, they would
    not be required to register today. True enough, their former
    No. 19-2523                                                    21
    states of residence also required them to register. Indiana is
    choosing to continue (or as to Bash and Snider, resurrect)
    those obligations. But what matters for purposes of the plain-
    tiffs’ constitutional claim is that they are now Indiana citizens.
    And because they are citizens who relocated (traveled) to In-
    diana from other jurisdictions, they are subject to burdens
    that Indiana pre-SORA offenders are not by virtue of the Wal-
    lace decision. Indiana has thus created two classes of other-
    wise similarly situated citizens based on whether or not they
    previously lived (or were otherwise present) in a state that re-
    quired them to register. The distinction is purposeful, as it ex-
    pressly looks to what obligations have been imposed on a per-
    son elsewhere to determine what obligations he will now
    have within the borders of Indiana. This disparate treatment
    is incompatible with the Supreme Court’s right-to-travel ju-
    risprudence, as we now explain.
    Although a right to travel is not expressly mentioned in
    the Constitution, it is nonetheless firmly embedded in federal
    jurisprudence. Saenz v. Roe, 
    526 U.S. 489
    , 498, 
    119 S. Ct. 1518
    ,
    1524 (1999). See also Attorney General of N.Y. v. Soto-Lopez, 
    476 U.S. 898
    , 901, 
    106 S. Ct. 2317
    , 2320 (1986) (“Freedom to travel
    throughout the United States has long been recognized as a
    basic right under the Constitution.”) (cleaned up); Shapiro v.
    Thompson, 
    394 U.S. 618
    , 629, 
    89 S. Ct. 1322
    , 1329 (1969) (“This
    Court long ago recognized that the nature of our Federal Un-
    ion and our constitutional concepts of personal liberty unite
    to require that all citizens be free to travel throughout the
    length and breadth of our land uninhibited by statutes, rules,
    or regulations which unreasonably burden this movement.”),
    overruled in part on other grounds by Edelman v. Jordan, 
    415 U.S. 651
    , 671, 
    94 S. Ct. 1347
    , 1359–60 (1974). Indeed, the short-lived
    Articles of Confederation expressly recognized a right of “free
    22                                                     No. 19-2523
    ingress and regress to and from any other State” and entitled
    the free inhabitants of each state to “all privileges and immun-
    ities of free citizens in the several States.” Articles of Confed-
    eration, art. IV, § 1 (1778).
    As the cases have defined it, the right to travel encom-
    passes at least three distinct, but related, components: (1) the
    right of a citizen of one state to enter and leave another state;
    (2) the right of a citizen of the first state to be treated as a wel-
    come visitor rather than an unfriendly alien by the second
    state; and (3) the right of a traveler who elects to settle in and
    become a permanent resident of another state to be treated on
    par with other citizens of that state. Saenz, 
    526 U.S. at 500
    , 
    119 S. Ct. at 1525
    .
    The parties agree it is the third right, if any, that is impli-
    cated here. So far as the plaintiffs in this case are concerned,
    whether or not SORA imposes a duty to register depends
    upon whether one settled (or re-settled) in Indiana after the
    relevant provision of SORA was enacted: A sex offender who
    lived in Indiana before the other jurisdiction requirement was
    adopted and has remained a citizen of Indiana since that time,
    without taking a job or engaging in some other activity in an-
    other state that triggers a duty to register in that state, is ex-
    empt from SORA’s other jurisdiction requirement, whereas
    an individual with the identical criminal history who relo-
    cated to Indiana after that requirement was adopted in 2006,
    from a state that compelled him to register there, is subject to
    SORA’s registration requirement.
    Historically, there has been some uncertainty as to the con-
    stitutional underpinning of the right to travel and thus as to
    the appropriate framework for evaluating claims that a state
    provision like SORA intrudes upon that right. The right to
    No. 19-2523                                                              23
    travel has been variously ascribed to the Privileges and Im-
    munities Clause of Article IV of the Constitution (the succes-
    sor to a kindred provision in the Articles of Confederation),
    the Commerce Clause, and the Privileges or Immunities
    Clause of the Fourteenth Amendment. Soto-Lopez, 
    476 U.S. at 902
    , 
    106 S. Ct. at 2320
    . And, as relevant here, a number of cases
    evaluating the legitimacy of state statutes according benefits
    to residents based on the date of their arrival to or the dura-
    tion of their residence within a state have examined those
    classifications under the Equal Protection Clause of the Four-
    teenth Amendment. See, e.g., Hooper v. Bernalillo Cnty. Asses-
    sor, 
    472 U.S. 612
    , 618 & n.6, 623,

    , 60–64 & n.6,

    But the Court’s decision in Saenz placed the third compo-
    nent of the right to travel squarely within the domain of the
    Privileges or Immunities Clause of the Fourteenth Amend-
    ment, which provides:
    All persons born or naturalized in the United
    States, and subject to the jurisdiction thereof, are
    citizens of the United States and of the State
    13 “Durational residency requirements are those that demand a person re-
    side in a state for a given period of time before gaining benefits. Fixed-
    point residency requirements demand that at a legislatively determined
    moment (a specific date or event, for example, a veteran’s date of enlist-
    ment) the applicant was a resident in the state. While an unsuccessful ap-
    plicant can satisfy a durational residence requirement in the future, an ap-
    plicant who fails to satisfy a fixed-point residence requirement cannot
    cure the defect with the passage of time.” Harris v. Hahn,

    526 U.S. at
    502–03, 
    119 S. Ct. at 1526
    . Saenz concerned a California statute which, for
    a period of twelve months after a new resident’s arrival, lim-
    ited the maximum welfare benefits available to that resident
    to the amount he was eligible to receive in the state where he
    formerly resided (assuming that amount was less than Cali-
    fornia’s relatively generous benefits). This durational resi-
    dency provision, the Court observed, implicated “the right of
    the newly arrived citizen to the same privileges and immuni-
    ties enjoyed by other citizens of the same State. That right is
    protected not only by the new arrival’s status as a state citizen,
    but also by her status as a citizen of the United States.” 
    Id. at 502
    , 
    119 S. Ct. at 1526
    . And it is this latter right that the Four-
    teenth Amendment’s Privileges or Immunities Clause ex-
    pressly addresses:
    Despite fundamentally differing views concern-
    ing the coverage of the Privileges or Immunities
    Clause of the Fourteenth Amendment, most no-
    tably expressed in the Slaughter-House Cases, 
    16 Wall. 36
    , 
    21 L. Ed. 394
     (1872), it has always been
    common ground that this Clause protects the
    third component of the right to travel. Writing
    for the majority in the Slaughter-House Cases,
    Justice Miller explained that one of the privi-
    leges conferred by this Clause “is that a citizen
    of the United States can, of his own volition, be-
    come a citizen of any State of the Union by a
    No. 19-2523                                                 25
    bonâ fide residence therein, with the same rights
    as other citizens of the State. 
    Id., at 80
    . Justice
    Bradley, in dissent, used even stronger lan-
    guage to make the same point:
    The states have not now, if they
    ever had, any power to restrict
    their citizenship to any classes or
    persons. A citizen of the United
    States has a perfect constitutional
    right to go to and reside in any

    Insofar as the plaintiffs here are concerned, Indiana’s
    SORA creates two classes of Indiana citizens, with the 2006
    adoption of the other jurisdiction requirement marking the di-
    viding line between the two classes: those who resided in In-
    diana prior to the enactment of SORA’s other jurisdiction re-
    quirement (and remained residents thereafter without incur-
    ring a registration obligation in any other state), and those
    who arrived later. The former enjoy the full protection of In-
    diana’s ex post facto clause as interpreted by Wallace and may
    not be burdened with the various aspects of the duty to regis-
    ter that Wallace deemed to be penalties, so long as they do not
    venture out of the State to engage in activity that might sub-
    ject them to a registration requirement elsewhere. If, however,
    they settled in Indiana after the other jurisdiction provision of
    SORA was enacted, they may be subject to those very penal-
    ties, regardless of when they committed their offenses.
    This sets up the very sort of multi-tiered state citizenship
    that the Supreme Court’s right-to-travel cases prohibit. See

    greater burdens on newly arrived residents. In this respect,
    newer citizens of Indiana—including the plaintiffs—are not
    accorded the same rights as more longstanding residents who

    The discriminatory application of SORA to newer resi-
    dents does not satisfy this demanding standard and, indeed,
    the State’s counsel conceded at oral argument that it cannot
    do so. Indiana surely has a strong interest in protecting its res-
    idents from the potential predations of convicted sex offend-
    ers. We may assume arguendo that SORA’s requirements fur-
    ther that interest. But singling out only newer citizens with a
    history of sex offenses to the exclusion of more longstanding
    citizens with the same criminal history does not further that
    interest: the distinction is not even rational. Cf. F.C.C. v. Beach

    pointed to no evidence indicating, nor does the State suggest,
    that individuals who began to reside in Indiana after the other
    jurisdiction provision of SORA was enacted are more likely to
    re-offend than those who were already residents prior to that
    time. Below, the State suggested that absent this arrangement,
    an individual currently living in another state whose sex of-
    fense predates SORA’s other jurisdiction provision but who is
    subject to registration in that other state might have an incen-
    tive to relocate to Indiana in order to evade registration. But
    we have no reason to suspect that a move to Indiana would
    be prompted by that incentive as opposed to the prospect of
    a better job, a wish to be close to family, or Indiana’s lower
    cost of living, and the State itself has abandoned this argu-
    ment on appeal. In any case, the aim of deterring in-migration
    to Indiana from other states is constitutionally impermissible.
    See Saenz, 
    526 U.S. at 506

    394 U.S. at 631
    , 
    89 S. Ct. at 1329
    ).
    We recognize, as the district court did, that the Indiana
    legislature may have wished to avoid this discriminatory clas-
    sification and instead apply SORA’s requirements to all sex
    offenders residing in Indiana, regardless of the date of their
    convictions, but that it was precluded from doing so by Wal-
    lace’s holding that imposing a registration requirement on of-
    fenders whose convictions pre-dated SORA’s regulatory re-
    quirements violated Indiana’s ex post facto provision. So the
    distinction may well be driven more by the Indiana Supreme
    Court’s holding in Wallace than by any legislative judgment
    No. 19-2523                                                      31
    as to the relative risks posed by newer and more longstanding
    residents. But that merely makes plain the point that the clas-
    sification deprives newer residents of a valuable right granted
    by the Indiana Constitution—the right not to be penalized for
    offenses of which they were convicted before the other juris-
    diction provision of SORA was enacted.
    Against all of this, the State as noted argues that the right
    to travel as recognized in cases like Saenz is, in reality, not bur-
    dened here, in that the applicability of SORA is tied not to the
    duration of one’s residency in Indiana but rather to the SORA-
    like requirements to which arriving citizens were subject in
    their former states of residence. In other words, from the
    State’s point of view, what triggers SORA is not the recency
    of one’s arrival to Indiana but the registration requirement to
    which the new resident was subject in his former state; and in
    that respect, Indiana is simply choosing to leave in effect (or
    reimpose) the very requirement that would have burdened
    the offender had he never traveled across state lines at all.
    And if the new arrival was not subject to a registration re-
    quirement in his former state of residence, Indiana will not
    impose one. The fact that the other jurisdiction requirement
    can also apply to a lifelong Indiana resident who becomes
    subject to a registration requirement in another state by virtue
    of his work, study, or other activity in that state reinforces the
    State’s point.
    But for at least three reasons, the argument is unavailing.
    First, notwithstanding Indiana’s insistence that its scheme is
    not tied to the duration of one’s residency, for individuals like
    the plaintiffs, the fact of one’s relocation from another
    jurisdiction is necessarily and implicitly an element of the
    other jurisdiction requirement, as one cannot become subject
    32                                                   No. 19-2523
    to this provision of SORA without having moved to Indiana
    from another state (where he was required to register); it is
    this relocation from one state to another that brings the third
    component of the right to travel into play. See A.W., 865 F.3d
    at 1020 n.3 (noting that construing Nebraska’s SORA to
    compel juvenile to register based on registration obligation
    imposed by Michigan before he relocated to Nebraska would
    “raise[ ] troubling implications under the third prong of the
    right to travel”). That connection is most clearly illustrated by
    application of the other jurisdiction requirement to Hope:
    Hope, having committed his offense in Indiana pre-SORA,
    would not have been required to register but for the fact that
    he later relocated to Texas and was required to register there;
    his subsequent decision to return to Indiana was what
    triggered a duty to register under SORA’s other jurisdiction
    requirement. Had he never left Indiana, he would not have
    been required to register. Furthermore, the timing of a
    person’s relocation to Indiana is a critically important factor
    in the application of SORA. As we have said, for the Indiana
    citizen who was living in Indiana before the other jurisdiction
    requirement was added to SORA in 2006, there will be no
    obligation to register unless he chooses to leave the State for
    work or other activity which might trigger a registration
    requirement elsewhere. But for the individual who moves to
    Indiana after 2006, the other jurisdiction requirement will
    come into play and trigger a duty to register so long as he was
    subject to registration in his former state. In this respect, this
    case is not unlike Hooper, 
    472 U.S. 612
    , 
    105 S. Ct. 2862
    , in which
    a fixed-point residency requirement made one’s eligibility for
    a veteran’s tax exemption turn upon whether he was a
    resident of New Mexico as of a particular date. The Supreme
    Court held unequivocally that the State could not

    discriminate against its own citizens based on the timing of
    their arrival in the State. 
    Id. at 623
    , 105 S. Ct. at 2868.14 Here,
    relocation to Indiana after 2006 will not always trigger a
    requirement to register under SORA: If one was not required
    to register in his former home state, the move by itself will not
    require registration in Indiana. At the same time, relocation to
    Indiana from a jurisdiction where one was required to register
    is not the only way in which the other jurisdiction requirement
    is triggered: work, study, or other activity engaged in by an
    Indiana resident (however long-tenured) in another
    jurisdiction that requires him to register there will trigger a
    duty to register in Indiana. Even so, as to relocating citizens
    who arrive in Indiana after 2006, the other jurisdiction
    requirement operates to create two classes of otherwise
    similarly-situated residents, one of which must register and
    one of which need not. Cf. Saenz, 
    526 U.S. at
    497 & n.8, 
    119 S. Ct. at
    1523 & n.8 (because California public benefit levels were
    sixth highest in nation, its one-year cap on benefits for new

    727 F.2d 633
     (7th Cir. 1984), the City of
    Chicago had banned the possession of handguns beginning on April 10,
    1982, while grandfathering the rights of city residents who had registered
    their handguns before that date. The plaintiff, who had moved to Chicago
    from a suburb shortly after the handgun ordinance took effect and thus
    could not lawfully possess a gun, argued that the ordinance disadvan-
    taged new residents of the city and in that way interfered with his right to
    travel. We held to the contrary, noting that the ordinance did not “single
    out new residents of Chicago for discriminatory treatment.”

    Second, to the extent the State’s theory presumes that the
    other jurisdiction requirement applies to plaintiffs Bash and
    Snider, who relocated to Indiana before that requirement was
    added to SORA in 2006, a few additional words are in order.
    The State’s counsel has insisted that the other jurisdiction re-
    quirement applies to them as it does to the other plaintiffs be-
    cause Snider and Bash were required to register in their for-
    mer states of residence (Ohio in Bash’s case, Michigan in
    Snider’s). This is obviously consistent with the State’s broader
    point that the timing of one’s arrival in Indiana does not mat-
    ter. Our dissenting colleague shares this understanding. But
    we cannot see any possible reason why the Indiana Supreme
    Court’s Wallace decision permits this application given the
    timing of Bash’s and Snider’s arrival in Indiana. When Bash
    and Snider arrived in Indiana pre-2006, the other jurisdiction
    requirement was not yet in effect and, of course, that is the
    only provision on which the State now relies to justify their
    obligation to register. So, at the time they relocated to Indiana,
    they were in the same position as a lifelong resident of Indi-
    ana with a similar criminal history: there was no provision re-
    quiring them to register (at least not one the State is willing to
    rely upon now, or one that the Indiana Supreme Court has not
    found to be unconstitutional).15 Whatever registration
    15 As a factual matter, we know that Snider was nonetheless required to
    register when he moved to Indiana in 2003, presumably on the basis that
    his offense was the substantial equivalent of one that SORA deems
    No. 19-2523                                                            35
    requirements to which Bash and Snider had been subject else-
    where came to an end upon their becoming citizens of Indi-
    ana.16 Re-imposing a duty to register in 2006, when SORA was
    amended to include the other jurisdiction requirement, would
    not constitute a mere continuation of the registration obliga-
    tions to which these men were subject in their former states,
    which the Indiana Supreme Court has permitted; it would in-
    stead constitute a resurrection of an expired obligation and,
    to that extent, a material and detrimental change in their obli-
    gations as Indiana citizens. Compare Wallace, 905 N.E.2d at
    384 (“[SORA] violates the prohibition on ex post facto laws
    contained in the Indiana Constitution because it imposes bur-
    dens that have the effect of adding punishment beyond that
    which could have been imposed when [Wallace’s] crime was
    committed”), with Tyson v. State, 
    51 N.E.3d 88
    , 96 (Ind. 2016)
    (“[U]nlike Wallace, where the offender had no obligation to
    register anywhere before the Act was passed, Tyson was re-
    quired to register in Texas years before our statutory defini-
    tion was amended to include him …; the challenged
    registrable. But that was before the Wallace decision in 2009 made clear
    that this was not permissible under Indiana’s ex post facto clause. After
    Wallace was decided, Indiana freed Snider from any registration obligation
    until 2016, when, upon inquiry from Michigan (Snider’s former State of
    residence), Indiana again required him to register—this time, apparently,
    on the basis of the other jurisdiction requirement.
    16 New York’s SORA has been interpreted to require an offender’s contin-
    uing registration in that state notwithstanding his relocation to another
    state. Doe v. O’Donnell, 
    924 N.Y.S.2d 684
    , 686–87 (App. Div. 2011). It is
    likely an outlier in that regard, however. See Samantha R. Millar, Note,

    of Continued Registration under SORA After Leaving the State, 38 CARDOZO

    amendments merely lengthened that requirement. We simply
    cannot say that transferring the obligation upon moving is
    any more punitive than lengthening it to potentially last a life-
    time.”) (emphasis in original), State v. Zerbe, 
    50 N.E.3d 368
    ,
    371 (Ind. 2016) (“the significant responsibilities with respect
    to Zerbe’s registration are merely maintained across state
    lines, to be fulfilled where he currently lives and works”), and
    Ammons v. State, 
    50 N.E.3d 143
    , 145 (Ind. 2016) (per curiam)
    (“Because Ammons was already under an obligation to regis-
    ter [in Iowa] and [SORA’s other jurisdiction provisions] do

    effect such a material change in their obligations years after
    they became Indiana citizens is a puzzle, and one it never ex-
    plains: If Indiana’s ex post facto clause would forbid the appli-
    cation of the substantial equivalency requirement to any of
    the plaintiffs, as the State has conceded it would, why would
    it not also preclude the application of the other jurisdiction
    requirement to Snider and Bash, who relocated to Indiana be-
    fore there was any such requirement? The district court made
    no findings as to how SORA’s other jurisdiction requirement
    operates, in light of Wallace, vis-à-vis persons who arrived in
    Indiana before the requirement’s enactment (so far as we can
    discern, it was not asked to do so). But we can see no rationale
    for allowing the other jurisdiction prong to be applied to per-
    sons who arrived before the enactment of that provision and
    who were, in the years between their arrival and the enact-
    ment, free and clear of any lawful registration obligation. Cer-
    tainly, no Indiana case cited by the State or the dissent con-
    dones a revival, as opposed to a continuation across state
    lines, of a duty to register. Ultimately, we need not reduce this
    conclusion about Indiana law to a holding, as, at the end of
    No. 19-2523                                                    37
    the day, our conclusion about the right to travel precludes the
    State from imposing a registration requirement on any of
    these plaintiffs. It is worth noting, however, that even without
    our consideration of federal constitutional law, it seems that
    under the Indiana Supreme Court’s holding in Wallace, nei-
    ther Snider nor Bash (both of who arrived in Indiana prior to
    the enactment of the other jurisdiction requirement) should
    ever have been subject to a registration requirement in Indi-
    ana.
    Even if the State and the dissent are correct that, as a mat-
    ter of state law, the other jurisdiction requirement is fully ret-
    rospective and can properly apply to individuals like Bash
    and Snider, there remains a dichotomy among Indiana resi-
    dents based on the date of their arrival in Indiana. One who
    was a resident of Indiana before SORA required registration
    for his offense and remains so thereafter is not subject to a
    duty to register, period (Wallace leaves no doubt in that regard
    at all), whereas one who arrived in Indiana later may be sub-
    ject to registration pursuant to the other jurisdiction require-
    ment. In that respect, the timing of one’s relocation to Indiana
    still matters.
    Third, although the applicability of SORA as relevant here
    depends on whether or not a new citizen was subject to com-
    parable requirements elsewhere, the State’s theory that it is
    merely recognizing and choosing to continue a burden im-
    posed by another jurisdiction cannot somehow obviate the ef-
    fect that its actions have on the right to travel. Indiana may
    not be burdening newly-arrived sex offenders vis-à-vis the re-
    quirements that their former states of residence imposed on
    38                                                            No. 19-2523
    them, as our dissenting colleague emphasizes,17 but Indiana
    certainly is treating them less favorably as compared with sex
    offenders who lived in the State before SORA’s other jurisdic-
    tion requirement was enacted; and the relative burden Indi-
    ana imposes on new arrivals is necessarily one that penalizes
    the exercise of one’s constitutional right to relocate to another
    state. Indiana’s statutory scheme is no different in kind from
    California’s effort to temporarily cap a new citizen’s welfare
    benefits at the amount of assistance she received in her former
    state of residence (assuming that amount was lower than
    what California would otherwise provide). Nominally, that
    cap did not penalize and therefore did not dis-incentivize an
    indigent person’s decision to relocate to California, because
    she would not receive less than what she had in her former
    home state; in that sense, there was no direct burden imposed
    on the exercise of one’s right to travel from state to state.

    . But that was “beside the point”
    as far as the Supreme Court was concerned. 
    Ibid.
    17 It bears noting that in at least some cases, SORA’s other jurisdiction re-
    quirement increases the burden upon a newly arriving sex offender as
    compared with what would have been required of him in his former home
    State. Recall that Illinois required Rice to register only for a period of ten
    years following his release from prison. But because Rice qualifies as a
    “sexually violent predator” under SORA, Indiana requires him to register
    for life (although he does have the ability to petition for removal of this
    designation). But the Indiana Supreme Court has deemed such marginal
    effects on an offender’s obligations to be insufficient to trigger the state’s
    ex post facto clause. See Jensen v. State, 
    905 N.E.2d 384
     (Ind. 2009); Lemmon
    v. Harris, 
    949 N.E.2d 803
     (Ind. 2011); but cf. Gonzalez v. State, 
    980 N.E.2d 312
     (Ind. 2013) (increase of registration obligation from ten years to life
    violates ex post facto clause where limited opportunity to file petition for
    removal did not permit offender to argue he was rehabilitated and no
    longer posed a threat to the public).

    Were we concerned solely with actual deter-
    rence to migration, we might be persuaded that
    a partial withholding of benefits constitutes a
    lesser incursion on the right to travel than an
    outright denial of all benefits. See Dunn v. Blum-
    stein,

    , 339, 
    92 S. Ct. 995
    , 
    31 L.Ed.2d 274
     (1972). But since the right to travel embraces
    the citizen’s right to be treated equally in her
    new State of residence, the discriminatory clas-
    sification is itself a penalty.
    Saenz, 
    526 U.S. at
    504–05, 
    119 S. Ct. at 1527
    . That is precisely
    the problem here: As to relocating individuals, Indiana has
    established a two-tiered system of regulating offenders that is
    tied in the first instance to when the individual became a citi-
    zen of Indiana. For constitutional purposes, the relevant com-
    parison is not how Indiana treats an offender versus how his
    former state of residence treated him, but rather how Indiana
    distinguishes among its own citizens based on whether they
    arrived pre- or post-enactment of SORA’s other jurisdiction
    provision. Indiana grants the former the full protection of its
    ex post facto clause but deprives newer arrivals of the same
    protection. See Saenz, 
    526 U.S. at 502
    , 
    119 S. Ct. at 1526
     (third
    aspect of the right to travel encompasses “the right of the
    newly arrived citizen to the same privileges and immunities
    enjoyed by other citizens of the same State”); Soto-Lopez,

    , 
    106 S. Ct. at 2322
     (“the right to migrate protects
    residents of a State from being disadvantaged, or from being
    treated differently, simply because of the timing of their mi-
    gration, from other similarly situated residents”). And, unlike
    the California scheme at issue in Saenz, the burden that one
    incurs by arriving in Indiana after the enactment of SORA is
    not temporary, insofar as the plaintiffs here are concerned,
    40                                                   No. 19-2523
    but permanent. See Hooper, 
    472 U.S. at 623
    , 105 S. Ct. at 2869
    (“the Constitution will not tolerate a state benefit program
    that ‘creates fixed, permanent distinctions … between … clas-
    ses of concededly bona fide residents, based on how long they
    have been in the State”) (quoting Zobel, 
    457 U.S. at 59
    , 
    102 S. Ct. at 2312
    ). Indeed, on what we might call the State’s
    “lesser of two state citizenships” theory, Indiana would be
    free to create a boundless array of classes among its citizens
    tied to the greater regulatory burdens imposed by their for-
    mer home states (theoretically subjecting them to differential
    treatment on anything from tax rates to minimum drinking
    ages). The Supreme Court’s right-to-travel jurisprudence
    plainly forecloses such scenarios. See Saenz, 
    526 U.S. at 507

    119 S. Ct. at 1528

    To return to a key point of the dissent: No, the overlap be-
    tween the set of offenders whom SORA burdens with a regis-
    tration requirement and the set of offenders who relocate to
    Indiana is not complete. Some number of relocating individ-
    uals will not be affected by the other jurisdiction requirement
    because their former domiciles did not require them to regis-
    ter. And some number of offenders will be required to register
    not because they are relocating from other states where they
    registered but because they have commuted from Indiana for
    work or study to other states that mandated their registration.
    The latter group, as we have noted, has still engaged in inter-
    state travel, but not the sort of travel for relocation to another
    state that Saenz and the other residency cases address. Mem-
    bers of that group may have their own constitutional claim,
    but it is not one that is presented here. But the fact that relo-
    cation from one state to another is not the exclusive means of
    triggering the other jurisdiction requirement and does not in-
    variably result in a registration obligation in Indiana does not
    No. 19-2523                                                     41
    detract from the inescapable point that for the six plaintiffs
    here, relocating to Indiana from other states has yielded them
    a set of rights and obligations that is concretely different from,
    and more burdensome than, the rights and obligations of of-
    fenders who arrived in Indiana before they did.
    Our dissenting colleague cites Connelly v. Steel Valley Sch.
    Dist., 
    706 F.3d 209
     (3d Cir. 2013), in an effort to demonstrate
    that it is not the plaintiffs’ travel that explains their differen-
    tial treatment by Indiana. But key distinctions between Con-
    nelly and this case actually demonstrate the opposite.
    In Connelly, a Pennsylvania school district gave less credit
    to its teachers for prior out-of-state teaching experience than
    it did for in-state experience in establishing starting salaries.
    The plaintiff, who had lived and taught in Maryland before
    relocating to Pennsylvania, argued that he was being treated
    differently based on his former domicile in Maryland, in vio-
    lation of his right to travel. In rejecting that claim, the court
    emphasized that the school district was not treating its
    teacher-citizens differently based on where they came from.
    Rather, what mattered was where they gained their prior ex-
    perience. As a result, a former Maryland citizen whose prior
    teaching experience was in neighboring Pennsylvania (the
    two states share a border along the Mason-Dixon line) would
    receive full credit for his experience, whereas a lifelong Penn-
    sylvania citizen who previously taught in Maryland would
    receive only partial credit. 706 F.3d at 214–15. “[O]nly the
    teacher’s lack of Pennsylvania teaching experience—not his
    residency—would adversely affect his starting pay.” Id. at
    215. Any burden this scheme imposed on interstate travel
    was, at most, “incidental.” Id. The court went on to hold that
    the school district had a rational basis for paying its teachers
    42                                                  No. 19-2523
    differently based on the extent of their teaching experience in
    Pennsylvania: Teachers with experience working at Pennsyl-
    vania schools have a greater familiarity with the state’s edu-
    cational policies, procedures, and regulations and are likely
    to have a better grasp of what teaching methods are likely to
    be successful in achieving the state’s educational goals. Id. at
    216–17.
    Our colleague analogizes the registration obligation that
    an offender has borne in another state to the teaching experi-
    ence that the plaintiff in Connelly acquired in another state:
    both are historical facts, on their face unconnected to an indi-
    vidual’s travel, that may legitimately inform a state’s judg-
    ment as to how the individual should be treated as a newly-
    arrived citizen.
    The difference is that when other states required the
    plaintiffs to register, they did so based on the very same
    criminal history that Indiana itself would not treat as
    sufficient to require registration. Individual states are, of
    course, free to reach different conclusions about what offenses
    require registration—that is a feature of our federalist system
    of government. And just as states may compile their own lists
    of registrable offenses, they may (and do) reach different
    conclusions as to whether the ex post facto provisions in their
    own constitutions permit the retrospective imposition of a
    duty to register. Indiana has conceded that its own ex post facto
    provision, as construed by Wallace, prohibits the application
    of the Indiana SORA’s substantial equivalence requirement to
    the plaintiffs: they were all convicted before their offenses
    were identified as registrable offenses by the Indiana
    Legislature. Had they been Indiana citizens at the time of
    No. 19-2523                                                   43
    those offenses, and remained in Indiana thereafter, they could
    not have been required to register.
    So unlike the school district in Connelly, which relied on
    the mise en scène of one’s prior experience and the perceived
    qualitative differences between in-state and out-of-state
    teaching experience, Indiana is not relying on something that
    any of the plaintiffs did in another state that distinguishes him
    from an otherwise similarly-situated Indiana sex offender—
    e.g., commit another offense, violate the terms of his proba-
    tion, or fail to comply with his registration and reporting ob-
    ligations. No plaintiff did anything outside of Indiana that
    would have triggered an obligation to register under SORA
    had he done it in Indiana. Indiana is relying solely on another
    state’s judgment that registration was required in that other
    state, so long as the offender was present in that state. Upon
    his relocation to Indiana, the State requires each plaintiff to
    carry that obligation with him, notwithstanding the fact that
    Indiana itself would not have imposed that obligation in the
    first instance.
    A simplified hypothetical helps to make clear why it is the
    offender’s relocation to Indiana from another state that is the
    real trigger for the mandate that he register in Indiana. Con-
    sider two offenders, A and B, who are similar in all respects
    but for the fact that A lives in Indiana and B lives in Illinois.
    In 1993, both commit the same sex offense, are convicted in
    their respective states, and commence six-year prison terms.
    In 1994, both states enact laws requiring lifetime registration
    for the sex offense that A and B committed; but the Indiana
    legislature makes its registration obligation prospective only,
    whereas Illinois makes the obligation fully retrospective.
    Thus, when A is released from prison in 2000, he is not
    44                                                 No. 19-2523
    obliged to register in Indiana, but B must register in Illinois.
    In 2006, Indiana adopts a requirement obliging an Indiana
    resident who has been required to register in another jurisdic-
    tion to register in Indiana. In 2008, B moves to Indiana. Rely-
    ing on the other jurisdiction provision, Indiana demands that
    he register. Compare A and B, who are now both Indiana cit-
    izens. There is no difference in their criminal histories: They
    committed the same offense in the same year (and in all other
    respects are similar) so the danger that they pose to Indiana
    citizens is the same. But Indiana, in the exercise of its judg-
    ment, has not deemed the 1993 offense to be registrable, so A
    has never been required to register. Illinois required B to reg-
    ister for life, but now that he has moved to Indiana, that obli-
    gation is no longer operative. As a newly arrived citizen of
    Indiana, what distinguishes B from A? The answer is plain: B
    relocated from a state that required him to register. His travel
    is the one and only cause of his duty to register in Indiana,
    and in that regard, he is being treated differently from A, a
    lifelong resident of Indiana.
    The point is more clearly made if we assume that both A
    and B were Indiana citizens from the beginning and commit-
    ted the same sex offense in Indiana in 1993 and that B in 2008
    relocated briefly to (and established residency in) Illinois,
    which required him to register, before returning to Indiana
    the following year. Indiana, relying on the other jurisdiction
    provision, now requires B to register in Indiana as well. Has
    B’s criminal history changed? No. Did he do anything that
    materially changed the risk that he might pose to his fellow
    Indiana citizens? No. All that occurred was his move to an-
    other state that required him to register before he returned to
    and re-established residency in Indiana.
    No. 19-2523                                                   45
    The plaintiffs no doubt belong to a relatively small class:
    They all committed their crimes before those offenses became
    registrable in Indiana (twenty-five or more years ago) and be-
    fore Indiana adopted the other jurisdiction requirement (four-
    teen years ago). With the passage of time, this class will dis-
    appear, and any individual who commits a sex offense will
    have been on constructive notice that registration is an obli-
    gation that he will have to shoulder.
    But however small in number the plaintiffs may be, Indi-
    ana has assigned them to a class of citizenship that is inferior
    to that enjoyed by other, similarly situated Indianans, and for
    the plaintiffs, it is their relocation from other states that has
    resulted in that second-class status. Indiana, as a matter of its
    own statutes and judicial precedents, would not have re-
    quired the plaintiffs to register had they lived in Indiana prior
    to 2006, when the other jurisdiction requirement was enacted.
    Only their travel from states that did require them to register
    has triggered this burden. The Supreme Court’s right-to-
    travel jurisprudence instructs that this two-tiered model of
    state citizenship is not permissible under the Fourteenth
    Amendment’s Privileges or Immunities Clause. A sex of-
    fender who has paid his debt to society has the right to relo-
    cate to Indiana like any other individual and be treated on
    equal terms with other similarly-situated citizens. These
    plaintiffs have been denied that equitable treatment. Indiana
    has, in effect, told the plaintiffs, “You are not from here. In-
    stead of applying our rules to you, we will apply your former
    state’s rules.” In this way, the plaintiffs remain outsiders in
    Indiana’s regulatory framework.
    Indiana nonetheless argues that because it is not denying
    newer arrivals a public benefit, a tax exemption, or the right
    46                                                                No. 19-2523
    to vote,18 the Supreme Court’s right-to-travel cases are inap-
    plicable. It may be true as a factual matter that the Court’s du-
    rational and fixed-point residency cases have not addressed
    the right to travel beyond these sorts of factual contexts.19 But
    to return to first principles, the right at issue here is the right
    18 See, e.g., Dunn v. Blumstein, 
    405 U.S. 330
    , 
    92 S. Ct. 995
     (1972) (state laws
    requiring prospective voter to have been resident for one year in state and
    three months in county penalize individuals who have migrated to state
    in order to establish new residence during qualifying period, thereby in-
    terfering with right to travel and violating equal protection).
    19 It is worth noting, however, that the Court’s decision in Edwards v. Cal.,
    
    314 U.S. 160
    , 
    62 S. Ct. 164
     (1941) invalidated a California statute that made
    it a criminal offense to bring a non-resident indigent person into the state.
    The statute was born of fears triggered by the massive influx of migrants
    from other states as a result of the Dust Bowl and the Great Depression
    and the “problems of health, morals, and especially finance” attributed to
    that influx. 
    Id. at 173
    , 62 S. C.t at 167. The Court pointed out that among
    the opportunities this exclusionary statute deprived indigent persons was
    “the opportunity to exert political pressure upon the California legislature
    in order to obtain a change in policy.” Id.at 174, 
    62 S. Ct. at 167
    . Because
    the statute was aimed at excluding indigents from the state, it arguably
    implicated all three components of the right to travel; and, indeed, the
    Court’s majority concluded that the statute interfered with interstate com-
    merce and as such was inconsistent with the Commerce Clause.

    62 S. Ct. at

    Amendment’s Privileges or Immunities Clause, making clear that among
    the rights implicated by the statute was a right of national citizenship that
    precludes a state from creating different classes among its residents with
    different rights. See

    Saenz, 
    526 U.S. at
    502–05, 
    119 S. Ct. at
    1526–27. Nothing in the
    Supreme Court’s jurisprudence concerning this right is tied to
    the nature of the particular benefit at issue; the right is one to
    citizenship on the same terms as other residents of the state.
    See ibid.; Soto Lopez, 
    476 U.S. at 904
    , 
    106 S. Ct. at 2322
    ; Hooper,
    
    472 U.S. at 623
    , 105 S. Ct. at 2868–69. SORA imposes a signifi-
    cant and lasting burden on a class of citizens who are other-
    wise similarly situated to those whose Indiana citizenship
    pre-dates the statute’s other jurisdiction requirement. As we
    have said many times now, those persons who were citizens
    of Indiana and were convicted of sex offenses before SORA’s
    other jurisdiction requirement was enacted enjoy the full pro-
    tection of the State’s ex post facto clause as construed in Wal-
    lace, and they are exempt from the various registration and
    reporting requirements that SORA imposes on such offend-
    ers. But those persons who were convicted of sex offenses be-
    fore the other jurisdiction requirement was enacted but have
    since relocated to Indiana are deemed subject to SORA’s reg-
    istration and other requirements—provisions that Wallace
    deemed punitive—so long as their former states imposed
    comparable requirements on them. In no sense are these two
    classes of Indiana citizens being treated equally: one is af-
    forded a valuable, constitutionally mandated protection
    against the after-the-fact imposition of what the Indiana Su-
    preme Court has labeled penalties, and one is not.
    Finally, Indiana posits that any understanding that a state
    cannot classify its citizens differently depending on whether
    they have engaged in interstate travel is inconsistent with the
    many federal criminal laws that apply precisely on that basis.
    This is a misguided argument. First, the sort of interstate
    48                                                 No. 19-2523
    travel to which Indiana is referring implicates a different com-
    ponent of the constitutional right to travel than the right,
    upon relocating from one state to another, to be treated on
    equal terms with other citizens in one’s new home state. The
    latter component is the only one at issue here. Second, federal
    criminal law does not create separate classes of citizens within
    a state who enjoy lesser or greater rights depending upon
    when they became citizens of that state. It simply employs the
    jurisdictional “hook” of conduct within interstate commerce
    to regulate, on equal terms, all who move or act across state
    lines. This has nothing to do with the classes Indiana has es-
    tablished within its own citizenry.
    III.
    The other jurisdiction requirement of Indiana’s SORA im-
    poses a duty to register and its attendant burdens upon a re-
    locating citizen that it would not impose upon a lifelong Indi-
    ana resident. The Privileges or Immunities Clause of the Four-
    teenth Amendment prohibits this differential treatment. We
    affirm the district court’s judgment on this basis, without
    reaching the separate question of whether application of the
    other jurisdiction requirement also violates the ex post facto
    clause of the U.S. Constitution.
    AFFIRMED
    No. 19-2523                                                   49
    ST. EVE, Circuit Judge, dissenting. I disagree with the ma-
    jority’s conclusion that the Indiana Supreme Court’s interpre-
    tation of the Indiana Constitution’s Ex Post Facto Clause as
    applied to Indiana’s Sex Offender Registration Act (SORA)
    implicates plaintiffs’ right to travel under the Privileges or Im-
    munities Clause of the Fourteenth Amendment of the United
    States Constitution. I write separately to explain my reason-
    ing.
    I.
    A.
    Addressing the plaintiffs’ federal claims requires a deep
    dive into Indiana law and the reasons for Indiana’s complex
    rules surrounding SORA. The majority starts off on the wrong
    foot by misunderstanding those rules.
    Like other states, Indiana requires persons convicted of
    sex offenses to register as sex offenders. 
    Ind. Code § 11-8-8-1
    to -23. Under SORA, a person must register if he (1) commit-
    ted a registrable offense under Indiana law, (2) committed a
    crime under the laws of another jurisdiction that is substan-
    tially equivalent to Indiana’s registrable offenses, 
    Ind. Code § 1-1-2-4
    (b)(3) (formerly 
    Ind. Code § 11-8-8-5
    (a)(24)), or (3) is
    required to register in any other jurisdiction, 
    Ind. Code § 11
    -
    8-8-5(b)(1).
    As a statutory matter, SORA is fully retrospective and
    does not depend on when someone was convicted of an of-
    fense. And as a federal constitutional matter, this retrospec-
    tive application is not inherently suspect under the Federal Ex
    Post Facto Clause. See Smith v. Doe, 
    538 U.S. 84
    , 90 (2003). The
    Indiana Supreme Court, however, has interpreted its state
    constitution’s Ex Post Facto Clause such that persons who
    50                                                  No. 19-2523
    would be required to register as a statutory matter are not re-
    quired to register as a constitutional matter. This began with
    Wallace v. State, 
    905 N.E.2d 371
     (Ind. 2009), in which the court,
    applying its own version of the U.S. Supreme Court’s “intent-
    effects” test, held that SORA had a punitive effect on those
    who had been charged, convicted, and served their sentences
    before SORA was enacted. 
    Id. at 379, 384
    .
    Even after Wallace, however, not all applications of SORA
    to prior convictions offend the Indiana Constitution. On the
    same day as Wallace, the Indiana Supreme Court decided Jen-
    sen v. State, 
    905 N.E.2d 384
     (Ind. 2009). Jensen was convicted
    of a sex offense in 2000, and at the time, SORA required him
    to register as a sex offender for ten years. 
    Id. at 389
    . Before
    Jensen’s ten years were up, the Indiana General Assembly
    amended SORA in 2006 to mandate that he now register for
    life. He argued that this extension violated the state’s Ex Post
    Facto Clause, but the Indiana Supreme Court disagreed. Un-
    like Wallace, who had no obligations before SORA was
    amended to cover him, the “‘broad and sweeping’ disclosure
    requirements were in place and applied to Jensen at the time
    of his guilty plea in January 2000. Nothing in that regard was
    changed by the 2006 amendments.” 
    Id. at 394
    . The marginal
    effect of increasing only the length of an existing registration
    obligation did not rise to the level of “punishment” such that
    it violated the Indiana constitution. 
    Id.
     at 391–93.
    After Jensen, the Indiana Supreme Court continued to fo-
    cus on the marginal effects of SORA and its amendments. In
    State v. Pollard, 
    908 N.E.2d 1145
     (Ind. 2009), it said that a new
    residency restriction was “adding punishment.” 
    Id. at 1154
    .
    The court’s decision in Lemmon v. Harris, 
    949 N.E.2d 803
     (Ind.
    2011), though, concluded that an amendment that reclassified
    No. 19-2523                                                       51
    someone from a sex offender to a “sexually violent predator”
    was not punitive because, just like for Jensen, it amounted
    only to an extension of pre-existing obligations and was not
    “any more punitive.” 
    Id.
     at 810–11, 813 n.19.
    Up to this point, however, each case had asked whether
    the Indiana SORA had a marginal punitive effective com-
    pared to those requirements already imposed by Indiana law.
    In 2016, the Indiana Supreme Court encountered three cases
    challenging SORA’s effect on those who had been required to
    register under another state’s laws.
    Applying the same marginal-effects test, the Indiana Su-
    preme Court concluded that the effect of maintaining an out-
    of-state registration in Indiana was not punitive, regardless of
    when or where the registrable crime had been committed.
    First, in Tyson v. State, 
    51 N.E.3d 88
     (Ind. 2016), the court up-
    held registration for a man obligated to register under Texas
    law at the time of his conviction, before Indiana’s SORA cov-
    ered his offense. 
    Id. at 92
    . The court concluded that the mar-
    ginal effect of “maintaining a registry requirement across
    state lines does not amount to a punitive burden” in violation
    of the state constitution. 
    Id. at 90
    .
    The court extended this reasoning in State v. Zerbe, 
    50 N.E.3d 368
     (Ind. 2016). Zerbe was convicted in Michigan in
    1992, before either Michigan or Indiana had enacted sex of-
    fender registration laws. 
    Id. at 369
    . Zerbe was nevertheless re-
    quired to register under Michigan law upon release from
    prison because Michigan did not share Indiana’s stricter Ex
    Post Facto Clause. 
    Id. at 371
    . This twist changed nothing; the
    marginal effect of maintaining that registration was not puni-
    tive. 
    Id.
     at 370–71. As the court clarified, “it is not Zerbe’s crime
    that triggers his obligation to register as a sex offender in
    52                                                    No. 19-2523
    Indiana; rather, it is his Michigan registry requirement that does
    so.” 
    Id. at 370
     (emphasis in original). The trilogy finished with
    Ammons v. State, 
    50 N.E.3d 143
     (Ind. 2016) (per curiam). Am-
    mons had been convicted in Indiana before SORA, but he
    moved to Iowa, which obligated him to register for his Indi-
    ana crime. 
    Id.
     When he moved back to Indiana, the Indiana
    Supreme Court confirmed that, just like for Tyson and Zerbe,
    maintaining Ammons’s Iowa registration for his Indiana
    crime did not amount to “additional punishment.” 
    Id. at 145
    .
    In sum, the question under SORA and Indiana’s Ex Post
    Facto Clause is always whether SORA’s marginal effect is pu-
    nitive. Maintaining, extending, or modifying a duty under
    SORA generally is not punitive, but imposing a new duty is.
    It is immaterial to the analysis whether Indiana law is main-
    taining, extending, or modifying its own duties or those of an-
    other state. Likewise, it is immaterial where or when the con-
    viction occurred, as long as some state imposed a lawful reg-
    istration obligation on the offender and SORA does not so sig-
    nificantly alter that obligation to result in added punishment.
    B.
    Plaintiffs argue that the Indiana Supreme Court’s
    marginal-effects rule violates their right to travel under the
    Federal Constitution. While the majority aptly summarizes
    the development of the law regarding this right, it overreads
    the right to travel as articulated by the Supreme Court.
    The U.S. Supreme Court has identified three components
    to the right to travel: (1) “the right of a citizen of one State to
    enter and to leave another State,” (2) “the right to be treated
    as a welcome visitor rather than an unfriendly alien when
    temporarily present in the second State,” and (3) “for those
    No. 19-2523                                                      53
    travelers who elect to become permanent residents, the right
    to be treated like the other citizens of that State.” Saenz v. Roe,
    
    526 U.S. 489
    , 500 (1999). Everyone agrees that only the third
    facet of the right is at issue here. That aspect is derived from
    the Privileges or Immunities Clause of the Fourteenth
    Amendment. U.S. Const. amend. XIV, § 2; Saenz, 
    526 U.S. at
    502–03.
    In Saenz, the plaintiffs challenged the constitutionality of a
    California statute that limited new residents to only the wel-
    fare benefits to which they would have been entitled in their
    prior state of residence. 
    526 U.S. at 492
    . The Supreme Court
    held that this rule violated the third aspect of the right to
    travel. The Court was not concerned with whether California
    was trying to penalize or deter travel or even if it was suc-
    ceeding. 
    Id. at 504
    . Instead, the Court found that “the right to
    travel embraces the citizen’s right to be treated equally in her
    new State of residence” and that “the discriminatory classifi-
    cation is itself a penalty.” 
    Id. at 505
    . In addressing this discrim-
    ination, the Court applied strict scrutiny, which California’s
    law failed. 
    Id.
     at 504–05. The duration of a citizen’s residency
    and the location of his or her prior residence had no relevance
    to the citizen’s welfare needs, and the bare desire to reduce
    the state’s budget was not compelling enough to justify a
    complex layered hierarchy among bona fide California resi-
    dents. 
    Id. at 507
    .
    Saenz broadly stands for the proposition that durational
    residency requirements violate the right to travel unless they
    pass strict scrutiny. The full scope of that right, however, is
    uncertain. There have been no Supreme Court decisions inter-
    preting the right to travel after Saenz. Decisions before it held
    other durational residency requirements unlawful but did so
    54                                                  No. 19-2523
    under the Equal Protection Clause. See Mem'l Hosp. v. Mari-
    copa Cty., 
    415 U.S. 250
    , 251, 261–62 (1974) (striking down a
    state law requiring an indigent person to be a county resident
    for one year to receive free medical care); Dunn v. Blumstein,
    
    405 U.S. 330
    , 334–35, 360 (1972) (holding unlawful a state law
    permitting only residents who have lived in state for one year
    to vote); Shapiro v. Thompson, 
    394 U.S. 618
    , 622 (1969) (invali-
    dating statutes that deny welfare assistance to individuals
    during their first year of residency). But see Sosna v. Iowa, 
    419 U.S. 393
    , 396, 409 (1975) (upholding an Iowa law requiring
    resident to live in state for one year to obtain a divorce de-
    cree).
    I agree with the majority, however, that the right to travel
    should be understood to go beyond prohibiting only
    durational residency requirements that place a waiting period
    on benefits. It seems unlikely that a permanent distinction
    between bona fide residents would be any more lawful than
    a temporary one. The Supreme Court’s cases illustrate this
    point, though a majority of the Court has yet to endorse it. In
    Zobel v. Williams, 
    457 U.S. 55
     (1982), Alaska implemented a
    natural resource dividend statute that created “fixed,
    permanent distinctions between an ever-increasing number
    of perpetual classes of concededly bona fide residents, based
    on how long they have been in the State.” 
    Id. at 59
    . The
    Supreme Court held that this scheme was improper even
    under rational-basis review. 
    Id. at 64
    . The Court did the same
    thing with a New Mexico tax exemption for Vietnam veterans
    who were state residents before a specific date. Hooper v.
    Bernalillo Cty. Assessor, 
    472 U.S. 612
    , 624 (1985).
    Although the Supreme Court did not directly hold that the
    laws at issue in Zobel and Hooper implicated the right to travel,
    No. 19-2523                                                    55
    a plurality of the Court later concluded that the right was re-
    ally driving those decisions. See Att’y Gen. of N.Y. v. Soto-
    Lopez, 
    476 U.S. 898
    , 907–08 (1986) (plurality opinion). In the
    plurality’s view, “a permanent deprivation of a significant
    benefit, based only on the fact of nonresidence at a past point
    in time, clearly operates to penalize appellees for exercising
    their right to migrate” and thus mandated strict scrutiny. 
    Id. at 909
    .
    All of the Supreme Court’s decisions in this area have
    something in common. Each involved a rule that explicitly
    discriminated between old and new residents. As the Court
    noted, the challenged classifications in Saenz were “defined
    entirely by (a) the period of residency in California and (b) the
    location of the prior residences of the [plaintiffs].” 
    526 U.S. at 505
     (emphasis added). Likewise, in Soto-Lopez, the plurality
    emphasized that New York was depriving the plaintiffs “of a
    significant benefit, based only on the fact of nonresidence at a
    past point in time.” 
    476 U.S. at 909
     (emphasis added). In each
    case, there was a direct causal connection between a person’s
    status as a new resident and the deprivation of a benefit. In
    legal parlance, each was a “disparate treatment” claim.
    II.
    The question in this case is whether Indiana’s registration
    requirement, as applied through the marginal-effects test, vi-
    olates the right to travel identified by the Supreme Court. In
    other words, does the marginal-effects test treat bona fide res-
    idents differently based on when they became residents.
    I part ways with the majority because I conclude it does
    not. Neither SORA nor Indiana’s Ex Post Facto Clause dis-
    criminates based on residency. Neither even mentions
    56                                                    No. 19-2523
    residency. As a statutory matter, SORA obligates all people—
    both old and new residents—to register based on prior con-
    victions. Indiana’s Ex Post Facto Clause then relieves a subset
    of those who must register from that statutory obligation.
    Who receives the clause’s benefits, though, does not depend
    on when one became an Indiana resident but on whether one
    is subject to an existing registration requirement. That re-
    quirement can come from Indiana or from another state. The
    twist in this case is that for those like the plaintiffs, convicted
    before Indiana’s SORA covered their crimes, such a registra-
    tion obligation must come from elsewhere. For the majority,
    that fact is determinative.
    The majority offers two theories to support its view that
    Indiana violated the plaintiffs’ right to travel. The primary
    argument is that the other-jurisdiction provision in SORA
    “creates two classes of Indiana citizens”: those who were
    Indiana residents prior to the provision’s enactment on July 1,
    2006, and those who moved to Indiana after that date. Because
    the provision applies only to newer Indiana residents who
    moved to the state after July 1, 2006, the argument goes, the
    provision impermissibly classifies Indiana residents based on
    the length of their residency in the state and generally treats
    newer residents worse than long-term Indianans. I disagree
    because the underlying premise to this conclusion is
    incorrect—the other-jurisdiction provision does apply
    retroactively to offenders who became Indiana residents prior
    to July 1, 2006.
    The majority’s conclusion to the contrary is rooted in its
    narrow reading of Indiana caselaw applying the state’s Ex
    Post Facto Clause to SORA. It suggests that any gap in time
    between the placement of an initial registration requirement
    No. 19-2523                                                             57
    and the later imposition of a related requirement transforms
    Indiana’s subsequent requirement into a “material change” in
    obligations rather than a “mere continuation” of them, failing
    the marginal-effects test. Under this logic, offenders who
    relocated to Indiana prior to July 1, 2006, and who were not
    required to register in Indiana until 2006 would be exempt
    from a later registration requirement under Wallace. That
    interpretation misapprehends Wallace’s more recent progeny:
    Tyson, Zerbe, and Ammons. While those cases dealt with
    plaintiffs who moved to Indiana after it enacted SORA’s
    other-jurisdiction provision in 2006, the Indiana Supreme
    Court did not base its decisions on that factor. Rather, it held,
    across three distinct factual patterns, that SORA’s retroactive
    application does not violate the state’s Ex Post Facto Clause
    as long as the offender is “already required to register in
    another jurisdiction.” Zerbe, 50 N.E.3d at 369–70. That
    condition is satisfied here. Because SORA’s other-jurisdiction
    provision may apply equally to Indianans who became
    residents prior to July 1, 2006, as well as those who move to
    the state after that date, the majority’s argument that SORA
    classifies Indiana residents by date of residency is
    unpersuasive.1
    The majority’s second, more implicit argument is that as a
    practical effect of Indiana’s SORA, out-of-state residency is a
    determinative factor in the plaintiffs’ case and that of other
    offenders like them. Undoubtedly having a registration obli-
    gation in another state is correlated with changing one’s state
    1 I likewise depart from the majority’s suggestion that Bash and Snider
    cannot be required to register under Indiana law; that conclusion depends
    upon an interpretation of Indiana law that bars retroactive application of
    SORA’s other-jurisdiction provision, which I reject.
    58                                                  No. 19-2523
    of residence, as we can see not only from the six plaintiffs here
    but also from Tyson, Zerbe, and Ammons, all of whom had to
    register after moving to Indiana. But the correlation is imper-
    fect. Some lifelong Indiana residents who committed crimes
    before SORA might well have a registration obligation based
    on their employment or schooling in an adjacent state. See,
    e.g., 730 ILCS 150/3(a-5) (requiring out-of-state students or
    employees to register in Illinois). On the flipside, some new
    Indiana residents who committed their crimes elsewhere
    might have no registration requirement in their prior state be-
    cause of state-law protection against retroactivity. See, e.g.,
    Doe v. State, 
    189 P.3d 999
    , 1004 (Alaska 2008) (holding that the
    state’s Ex Post Facto Clause prohibits retroactive application
    of SORA). While prior, out-of-state residency is often an ele-
    ment in the application of SORA’s registration requirements,
    residency is not the trigger for the other-jurisdiction provi-
    sion.
    The majority acknowledges this but suggests that the fact
    that some new residents are not adversely affected by SORA’s
    requirements does not immunize the law from unconstitu-
    tionality. For support, the majority points to Saenz. There, the
    Supreme Court struck down the law, even though some of the
    new residents experienced more favorable welfare benefits
    than long-term Californians. Saenz, 
    526 U.S. at 497
    . What mat-
    tered, the Court concluded, was that California explicitly
    based its provision of benefits to new Californians—favorable
    or not—on the duration of their residence in California. 
    Id. at 497, 505
    . The implication of the majority’s citation to Saenz is
    that SORA likewise cannot be saved by the fact that some new
    Indianans may not be subject to the registration requirements
    while some lifelong Indianans may be covered. That is a false
    equivalence. California employed an express, durational-
    No. 19-2523                                                      59
    residency classification; it applied to all persons who had re-
    sided in California for less than a year and happened to pro-
    duce a favorable effect for some of them. In contrast, SORA
    by its terms does not base its application on any length of res-
    idency in Indiana; new Indiana residents who arrive in Indi-
    ana without any prior registration requirements do not expe-
    rience a favorable effect under SORA—the law simply does
    not apply to them at all. In sum, Saenz involved a discrimina-
    tory test that some new residents passed, while SORA in-
    volves a non-discriminatory test that some new residents fail.
    Prior, out-of-state residency represents neither causation
    nor perfect correlation for the application of SORA’s
    registration requirements, and there is no evidence that
    anyone in Indiana intended to deter travel through the other-
    jurisdiction provision. The result? A disparate-treatment
    claim under the right to travel necessarily must fail. All that
    is left is a disparate-impact claim—an argument that, as a
    practical matter, more new residents than old residents must
    register under the law. The Supreme Court, though, has never
    extended the right to travel this far. Cf. Washington v. Davis,
    
    426 U.S. 229
    , 239 (1976) (holding that only disparate treatment
    or discriminatory purpose violates the Equal Protection
    Clause). Nor, to my knowledge, has any other court of
    appeals before today.
    The Third Circuit has actively refused to take this step,
    and I would follow its lead. In Connelly v. Steel Valley Sch. Dist.,
    
    706 F.3d 209
     (3d Cir. 2013), a Pennsylvania school district set
    its teachers’ salaries based on years of teaching experience but
    gave full credit for years teaching in the district, partial credit
    for years teaching in Pennsylvania, and reduced credit for
    years teaching elsewhere. 
    Id.
     at 211–12. A teacher who taught
    60                                                   No. 19-2523
    nine years in Maryland and received one year of credit argued
    that the school district’s salary scheme violated his right to
    travel.

    . The Third Circuit recognized that the district
    was not discriminating based on duration of residency but on
    location of teaching experience.

    . A lifelong Pennsyl-
    vania resident who taught across the border in Maryland
    would have received the same treatment as a similar Mary-
    land resident who moved to Pennsylvania.

    the Third Circuit’s view, “[t]he right to travel simply is not
    implicated when there is no discrimination based on the du-
    ration of one's residency." 
    Id. at 215
    . Because SORA likewise
    does not discriminate based on the duration of one’s resi-
    dency but rather on the existence of a registration obligation,
    I would conclude that it does not implicate the right to travel
    or merit strict scrutiny.
    There are good reasons for limiting the right to travel to
    actual discrimination, as we recognized more than a decade
    before Saenz. In Sklar v. Byrne, 
    727 F.2d 633
     (7th Cir. 1984), we
    considered a right-to-travel objection to an ordinance banning
    unregistered handguns in the City of Chicago. Because one
    needed to be a Chicago resident to register a handgun for law-
    ful possession—and Chicago stopped new registrations after
    1982—Sklar argued that the ordinance violated the right to
    travel.

     We recognized then that this could not be how the
    right to travel functions, for applying strict scrutiny “based
    merely on a showing that newer residents would not benefit”
    would make huge swaths of the law vulnerable.

    .
    Like in Sklar, the plaintiffs here want to apply strict scrutiny
    on the showing that they, as new residents, are “merely one
    group among several who do not benefit” from the protec-
    tions of Indiana’s Ex Post Facto Clause. 
    Id. at 639
    . We refused
    the invitation in 1984, and I would refuse it again now.
    No. 19-2523                                                      61
    The Privileges or Immunities Clause of the Fourteenth
    Amendment simply does not prohibit a state from inci-
    dentally burdening travel to or from the state. It guarantees
    only “the right of the newly arrived citizen to the same privi-
    leges and immunities enjoyed by other citizens of the same
    State.” Saenz, 
    526 U.S. at 502
    . Because both old and new Indi-
    ana residents are treated equally under SORA and Indiana’s
    Ex Post Facto Clause, I respectfully dissent from the major-
    ity’s holding that either law violates the right to travel.
    III.
    Because Indiana’s law does not implicate a fundamental
    right, it is subject to rational basis review. To survive this level
    of scrutiny, the Supreme Court has required that there be a
    rational basis for the classification. See FCC v. Beach Commc’ns
    Inc., 
    508 U.S. 307
    , 313 (1993) (stating that a statutory classifi-
    cation will survive rational-basis scrutiny “if there is any rea-
    sonably conceivable state of facts that could provide a rational
    basis for the classification”). Because the district court did not
    undertake a rational-basis review, I would remand this case
    to the district court to determine whether this level of scrutiny
    has been met.
