Cecilio Gonzalez was convicted by a jury of failing to update his annual sex offender registration within five working days of his birthday, in violation of California Penal Code § 290(a)(1)(D). 1 Because of his prior criminal convictions, he received a sentence of 28 years to life imprisonment under California’s “Three Strikes” law. On habeas review, we must decide whether his sentence violates the Eighth Amendment’s prohibition against cruel and unusual punishment and, if so, whether the contrary conclusion of the California Court of Appeal constituted an unreasonable application of clearly established federal law.
The California courts have characterized the state’s registration requirement as a regulatory offense, a “most technical violation” that “by itself, pose[s] no danger to society.”
People v. Cluff,
I
On August 10, 2001, Petitioner Cecilio Gonzalez, a convicted sex offender, was charged by information in Los Angeles County Superior Court with two felony violations of California’s sex offender registration statute, California Penal Code § 290(a)(1)(A), for allegedly failing to register a change of address on and between May 16, 2000 and May 31, 2001. The information further alleged that Gonzalez had been convicted of three serious or violent felonies that constituted “strikes” under California’s Three Strikes law.
Gonzalez pled not guilty. Prior to trial, he moved to proceed in propria persona. At a pretrial hearing on September 7, 2001, the superior court expressed concern about the possibility that Gonzalez1 would receive a life sentence even though the facts indicated that Gonzalez had attempted to comply with the registration requirements. The court thus encouraged Gonzales to accept a plea agreement in exchange for a midterm sentence of two years. Gonzalez maintained his innocence and refused to accept a plea. The court granted Gonzalez’s motion to proceed pro per.
*878 On September 10, 2001, the prosecution amended the information. Count 1 of the amended information alleged that Gonzalez failed to register a change of address on and between May 16, 2000, and May 31, 2001, in violation of California Penal Code § 290(a)(1)(A), and Count 2 alleged that he failed to update his registration within five working days of his February 24, 2001, birthday in violation of California Penal Code § 290(a)(1)(D). The amended information retained the allegation of three pri- or serious or violent felony convictions under California’s Three Strikes law.
Trial began on January 16, 2002. When the superior court asked if the parties were ready to begin, Gonzalez expressed his willingness to accept a plea agreement in exchange for a one year sentence. The court offered a four year sentence, which Gonzalez declined. Gonzalez moved for a Romero 2 hearing to permit the court to strike one or more of his prior felony convictions for Three Strikes sentencing purposes in the interest of justice. After a brief hearing, the superior court declined to strike any of the prior convictions.
The case proceeded to a jury trial, during which Gonzalez cross-examined prosecution witnesses and presented a defense. The government’s theory on Count 1 was that Gonzalez had moved twice without updating his sex offender registration: first, from his grandmother’s house in Lake View Terrace to his wife’s house in Chatsworth; and second, from the house in Chatsworth to an apartment he allegedly shared with his wife in North Hills.
The government’s basis for Count 2 was that Gonzalez had failed to update his registration within five working days of his February 24, 2001, birthday. Testimony established that the California Department of Corrections notified Gonzalez of his duty to register annually within five working days of his birthday on May 2, 2000. Gonzalez registered his Lake View Terrace address on May 23, 2000, nine months before his February 24, 2001, birthday. On the registration form, Gonzalez initialed the statement: “I must annually, within 5 working days of my birthday, go to the law enforcement agency having jurisdiction over my location or place of residence and update my registration information.” Gonzalez, however, did not update his registration until May 21, 2001, within one year of being advised of his duty to report annually, but three months after his birthday.
On January 23, 2002, the jury acquitted Gonzales of failing to register a change of address but convicted him of failing to update his registration annually within five working days of his birthday. At a bench trial to determine the validity of Gonzalez’s prior convictions, the prosecutor introduced abstracts of judgment for a 1988 conviction for cocaine possession, a 1989 conviction for committing a lewd act with a child under 14 years of age, a 1989 conviction for attempted rape by force, 3 and a 1992 conviction for second-degree robbery. The superior court found three prior serious or violent felony convictions under California’s Three Strikes law 4 and three prior prison terms, which each triggered *879 additional one-year sentence enhancements under California law. 5 Gonzalez renewed his Romero motion to strike his prior convictions, which the superior court denied. The superior court sentenced Gonzalez to an indeterminate period of 28 years to life imprisonment. The California Court of Appeal affirmed the sentence in an eight page unpublished opinion, and the California Supreme Court declined to hear the case on direct appeal.
Gonzalez filed state habeas petitions in the California Court of Appeal and the California Supreme Court, which were both summarily denied. Gonzalez then filed this 28 U.S.C. § 2254 petition for a writ of habeas corpus in the United States District Court for the Central District of California. A magistrate judge recommended denying Gonzalez habeas relief, and the district court adopted the recommendation and entered judgment dismissing the petition. Gonzalez timely filed a notice of appeal and applied for a certificate of appealability. We certified one issue: “whether appellant’s sentence of 28 years-to-life under California’s Three Strikes law violates the Eighth Amendment.” 6

We review the district court’s denial of a 28 U.S.C. § 2254 petition for a writ of habeas corpus
de novo. Silva v. Woodford,
Ill
The Eighth Amendment mandates that “[ejxcessive bail shall not be required, nor excessive fines imposed, nor cruel and unusual punishments inflicted.” “The final clause prohibits not only barbaric punishments, but also sentences that are disproportionate to the crime committed.”
Solem v. Helm,
First, in
Rummel v. Estelle,
the Court considered the imposition of a life sentence with the possibility of parole within 12 years under a Texas recidivist sentencing statute.
By contrast, in
Solem v. Helm,
the Court held that imposition of a life sentence
without the possibility of parole
under South Dakota’s recidivist sentencing statute was grossly disproportionate to the triggering offense of uttering a “no account” check for $100.
The Court announced three objective factors to guide review of a sentence for a term of years under the Eighth Amendment. First, a reviewing court must look to the gravity of the offense and the harshness of the penalty.
Id.
at 290-91,
In a third case,
Harmelin v. Michigan,
the Court upheld a life sentence without the possibility of parole for possession of more than 650 grams of cocaine. 501 U.S.
*881
957, 961, 996,
Justice Kennedy’s opinion, joined by Justices O’Connor and Souter, represented the narrowest view of a majority of the Court on the question of gross dispropor-tionality review.
See Marks v. United States,
Applying this methodology, Justice Kennedy concluded that Harmelin’s sentence, when compared with his crime, did not give rise to an inference of gross dispro-portionality, and thus that no further inquiry was required.
Id.
at 1008-09,
In a fourth case,
Ewing v. California,
the Court upheld a Three Strikes sentence of 25 years to life imprisonment for felony grand theft of personal property in excess of $400.
Even standing alone, Ewing’s theft should not be taken lightly. His crime was certainly not “one of the most passive felonies a person could commit.” To the contrary, the Supreme Court of California has noted the “seriousness” of grand theft in the context of proportionality review.
Id.
at 28,
Finally, in
Lockyer v. Andrade,
the Court upheld on federal habeas review a Three Strikes sentence of 25 years to life imprisonment for two petty theft convictions arising from the theft of $153.54 worth of videotapes.
The Supreme Court’s Eighth Amendment jurisprudence establishes that “no penalty is
per se
constitutional,” and that
“successful
challenges to the proportionality of particular sentences [are] exceedingly rare,”
Helm,
Although the principle may be “clearly established,” the details are not. In
An-drade,
the Court decried its own “lack of clarity regarding what factors may indicate gross proportionality,”
id.,
but declined to clarify the “gross disproportionality” standard, leaving us with a principle, but no explanation. As the Court itself framed the AEDPA standard we must apply here, “the only relevant clearly estab
*883
lished law amenable to the ‘contrary to’ or ‘unreasonable application of framework is the gross disproportionality principle, the precise contours of which are unclear.”
Id.
at 73,
Following
Andrade,
we have applied the gross disproportionality principle in a number of cases. In
Ramirez v. Castro,
for example, Ramirez shoplifted a $199 VCR and was convicted of one count of petty theft with a prior theft-related conviction, an offense punishable as a felony under California law.
As
Nunes v. Ramirez-Palmer,
IV
Having set forth this background, we now turn to whether “a threshold comparison of the crime committed and the sentence imposed” in this case “leads to an inference of gross disproportionality.”
Harmelin,
A. Inference of Gross Disproportionality
1. Gravity of the Offense
We weigh the criminal offense and the resulting penalty “in light of the harm
*884
caused or threatened to the victim or to society, and the culpability of the offender.”
Helm,
The purpose of California’s registration law is to prevent “recidivism in sex offenders” by assuring they are “available for police surveillance.”
Wright v. Superior Court,
By contrast, § 290(a)(l)(D)’s annual registration requirement, which Gonzalez was convicted of violating, is only tangentially related to the state’s interest in ensuring that sex offenders are available for police surveillance. Annual registration is merely a “backup measure to ensure that authorities have current accurate information.”
People v. Carmony,
Indeed, we are unable to discern any actual harm resulting from Gonzalez’s failure to comply with the annual registration requirement. Gonzalez updated his sex offender registration nine months before and three months after his February 24, 2001, birthday, and he remained at his last registered address throughout that time period. There is nothing in the record remotely indicating that Gonzalez’s failure to reregister the same address a third time in the same twelve month period could have interfered with the ability of police to monitor his activities. 8 The record confirms that Gonzalez was in fact “readily available for police surveillance”: Gonzalez was arrested “fairly close” to his registered address, and the arresting officers were familiar with Gonzalez and had spoken to him previously at that location. Id. *885 at 86 (“Cluff was exactly where he said he would be when he registered in 1995, and the police were able to quickly find him.”). We conclude that “[t]he purpose of the registration statute was not undermined by [Gonzalez’s] failure to annually update his registration.” Id.
In reviewing Three Strikes sentences triggered by violations of the sex offender registration law, California courts have recognized that the distinction between a conviction for failure to register after a change of address as required by § 290(a)(1)(A), and a conviction for failure to update registration annually as required by § 290(a)(1)(D), is critical. In
People v. Meeks,
the Court of Appeal held that imposition of a 25 years to life sentence for failure to register a change of address and a consecutive sentence of two years imprisonment for failure to update registration annually did not violate the Eighth Amendment.
9
The purpose of the sex offender registration law is to require that the offender identify his present address to law enforcement authorities so that he or she is readily available for police surveillance. In this case the defendant did so one month prior to his birthday and was in fact present at his registered address when the arrest for the present violation was made. The stated purpose of the birthday registration requirement was (and still is) to “update” the existing registration information.
Here, there was no new information to update and the state was aware of that fact. Accordingly, the requirement that defendant re-register within five days of his birthday served no stated or rational purpose of the registration law and posed no danger or harm to anyone.
Because a 25-year recidivist sentence imposed solely for failure to provide duplicate registration information is grossly disproportionate to the offense, shocks the conscience of the court and offends notions of human dignity, it constitutes cruel and unusual punishment under both the state and federal Constitutions.
Carmony,
Although we independently evaluate federal constitutional claims, in doing so we are bound by the California courts’ interpretations of California law.
See Powell v. Lambert,
*886
Carmony,
2. Severity of the Penalty
Gonzalez’s sentence of 28 years to life is “harsh ... beyond any dispute.”
Ramirez,
In comparison to the passive, harmless, and technical violation that triggered Gonzalez’s sentence, “the severe penalty imposed on [Gonzalez] appears disproportionate by any measure.”
Cluff,
Gonzalez’s criminal history is extensive, including convictions for possession of a controlled substance and auto theft in 1988, attempted forcible rape and lewd conduct with a child under the age of fourteen in 1989, robbery in 1992, and spousal abuse in 1999. We recognize that Gonzalez’s prior convictions, which include both crimes of violence and sexual predation, are very serious. We also acknowledge the state’s interest in deterring recidivism. Incarceration for a minimum of 28 years would incapacitate Gonzalez and thus prevent him from committing addi *887 tional Monies against the general population.
However, we are unable to discern any rational relationship between Gonzalez’s failure to update his sex offender registration annually and the probability that he will recidivate as a violent criminal or sex offender. There is no evidence that, as of 2001, Gonzalez was a recidivist. We agree with the California Court of Appeal’s conclusion in
Camony
that a sentence of 25 years to life imprisonment does not “protect the public when the
current
offense bears little indication [that the defendant] has recidivist tendencies to commit offenses that pose a risk of harm.”
Carmony,
Gonzalez’s present offense, does not reveal any propensity to recidivate. California certainly may be “justified in punishing a recidivist more severely than it punishes a first offender,”
Helm,
In sum, we conclude that Gonzalez’s sentence raises an inference of gross dispro-portionality. We thus turn to a comparative analysis of Gonzalez’s sentence.
See Harmelin,
B. Intrajurisdictional and Interjurisdic-tional Comparisons
Comparison of Gonzalez’s sentence with those imposed for other crimes in California and for the same crime in other states confirms our finding of gross dispro-portionality.
See Helm,
An interjurisdictional comparison similarly militates against California’s position. At least eleven states require a sex offender to renew registration within some statutorily fixed period after the initial registration but do not tie the registration requirement to the offender’s birthday; Gonzalez’s failure to update his sex of *888 fender registration within several days of his birthday thus would not have even qualified as a criminal offense in those states. See Ariz. Rev. Stat. Ann. § 13-3821(J); Del. Code tit. 11, § 4120(g); Idaho Code § 18 — 8307(5)(b); Iowa Code § 692A.4; La. Rev. Stat. Ann. § 15:542.1; Neb. Rev. Stat. § 29-4006(2); Nev. Rev. Stat. § 179D.480; N.J. Stat. Ann. § 2C:7-2(e); N.Y. Correct. Law § 168 — f; Pa. Cons. Stat. § 9796; Wis. Stat. § 301.45(3). In at least ten jurisdictions, a first registration offense is a misdemeanor. Alasea Stat. § 11.56.840(b); D.C. Code § 22-4015(a); Iowa Code § 692A.7(1); Me. Rev. Stat. Ann. tit. 34-A, § 11227; Md. Code Ann., Crim. Proc. § 11-721; Mass. Gen. Laws ch. 6, § 178H(a)(l); Mich. Comp. Laws §§ 28.725a(10), 28.729(2); Or. Rev. Stat. § 181.599;S.C. Code Ann. § 23-3-470(B)(1); W. Va. Code § 15-12-8(b). In at least ten states, sex offender registration violations are subject to separate recidivist statutes but such statutes punish those who fail to comply with registration requirements only for terms of imprisonment ranging from one to ten years. Alaska Stat. §§ 11.56.835(d), 12.55.125(e); Colo. Rev. Stat. §§ 16-22-108(l)(b), 18-3-412.5(2)(A), 18-1.3-401(l)(a)(V)(A); 18-1.3-801(2); Conn. Gen. Stat. §§ 54-254, 53a-35a, 53a~40(c), (j); Fla. Stat. Ann. § 775.084(l)(b) & 4(b)(3); Mass. Gen. Laws ch. 6, § 178H, § 178F, ch. 279, § 25; Miss. Code Ann. §§ 45-33-33(2); Mo. Ann. Stat. §§ 589.425(1), 558.016(3), 558.011(1)(3); N.M. Stat. §§ 29-llA-4(L), (N), 31-18-15(A)(9), 31-18-17(B), (C); N.D. Cent. Code §§ 12.1-32-15(9), 12.1-32-09(2)(c); Tenn. Code Ann. §§ 40-35-112(c)(5), 40-35-106(c), 40-35-107(c), 40-39-204(c), 40-39-208(b). An even larger number of states appear not to subject violators of sex offender registration requirements to separate recidivist statutes at all.
Several states
authorize
maximum recidivist sentences greater than ten years.
See
Ala. Code §§ 13A-5-9(c), 15-20-24; Ga. Code Ann. §§ 17-10-7(c), 42-l-12(n); Mont. Code Ann. §§ 46-23-507, 46-18-501-502; N.H. Rev. Stat. Ann. § 651-B:9(II), 651:6(II)(A), (III)(a); Okla. Stat. tit. 57, §§ 584(A)(5), 587, tit. 21, § 51.1(C); R.I. Gen. Laws §§ 11-37.1-14, 11-37.1-10, 12-19-21(a); S.D. Codified Laws §§ 22-24B-2, 22-7-8, 22-6-1(0 (2007). However, Texas appears to be the only state besides California that would
mandate
a sentence of 25 years or longer for a third felony offense, including a violation of a sex offender registration law.
See
Tex. Penal Code Ann. § 12.42(d).
See also Ramirez,
As we expect in our federal system, sex offender registration laws vary widely among the several states and are frequently changed.
12
We are thus hesitant to draw any conclusions from this survey; however, the fact that Gonzalez’s sentence is at the margin of what the states have deemed an appropriate penalty for violation of sex offender registration laws supports our finding that Gonzalez’s sentence is unusual.
See Helm,
V
Weighing both the gravity of the commitment offense and Gonzalez’s criminal history, we conclude that the sentence imposed of 28 years to life imprisonment is grossly disproportionate to the “entirely passive, harmless, and technical violation of the registration law,”
Carmony,
Here, the Court of Appeal properly stated the objective factors of
Solem v. Helm
that guide gross disproportionality review. Moreover, the facts of Gonzalez’s case are not “materially indistinguishable” from any decision of the United States Supreme Court.
See Williams,
The Court of Appeal failed, however, to apply these factors reasonably to the facts of Gonzalez’s case. After initially stating the proper factors, it relied on four general propositions to affirm Gonzalez’s sentence. It found that (1) the California Legislature has determined that sex offenders pose a “continuing threat to society” and must therefore be readily available for police surveillance by registering under section 290, (2) Gonzalez has a “significant criminal history” revealing that he “is a recidivist who has resisted prior efforts at rehabilitation,” (3) Gonzalez’s sentence “is not unlike others imposed under the Three Strikes law and upheld by the courts,” and (4) Gonzalez’s sentence “is consistent with the nationwide pattern of substantially increasing sentences for habitual criminals.”
The state court’s reasoning is unsound. First, the Court of Appeal vastly overstated the annual registration requirement’s relationship to police surveillance. The requirement that offenders update their addresses is indeed directly related to the need for police to be able to keep track of offenders but Gonzalez was
acquitted
of failing to update his address. The annual registration requirement set forth in § 290(a)(1)(D), by contrast, is merely a “backup measure” to ensure that police have current information.
See Carmony,
Second, we agree with the California Court of Appeal that Gonzalez’s criminal history is not insignificant. However, Gonzalez’s criminal history alone cannot support a sentence of 28 years to life imprisonment. The triggering offense in this case is “remote from and bear[s] no relation to the current offense and the current
*890
offense reveals no tendency to commit additional offenses that pose a threat to public safety.”
Carmony,
Third and contrary to the Court of Appeal’s assertion, Gonzalez’s sentence appears to be unlike sentences imposed for other violations of § 290(a)(1)(D). For example, in
Cluff,
the Court of Appeal held that the trial court had abused its discretion in refusing to strike prior convictions when sentencing a defendant for failure to annually update his registration,
The state court’s analysis resulted in an unreasonable application of the Supreme Court’s Eighth Amendment jurisprudence. The imposition of a 28 years to life sentence for failure to update a sex offender registration within five working days of the registrant’s birthday in this case is more extreme than the imposition of a sentence of life without parole for utterance of a no account check in
Helm.
In that case, the Supreme Court underscored that uttering a no account check was “one of the most passive felonies a person could commit ... involving] neither violence nor threat of violence to any person.”
Helm,
Although Solem remains the only Supreme Court decision finding a sentence grossly disproportionate to the triggering offense, none of the other Supreme Court decisions upholding sentences for a term of years — Rummel (false pretenses), Harmelin (drug possession), Ewing (grand theft) and Lockyer (petty theft) — involved regulatory offenses. Each of the property and drug crimes involved in those cases imposed a readily ascertainable social harm, in sharp contrast to the “harmless, and technical violation” committed by Gonzalez.
In addition, in the four Supreme Court decisions upholding sentences for a term of years, the defendant’s criminal history was directly related to the triggering offense, evincing a clear pattern of recidivism. In
Rummel
the triggering offense of obtaining $120.75 by false pretenses was related to past convictions for fraudulently using a credit card and passing a forged check. In
Ewing,
the triggering offense of felony
*891
grand theft was related to prior convictions for theft, grand theft auto, burglary, trespassing, and robbery. In
Andrade,
the triggering offenses of two petty theft convictions were related to prior convictions for misdemeanor theft and residential burglary. Here, Gonzalez’s failure to update his sex offender registration is categorically different from his past criminal conduct and does not demonstrate any recidivist tendency toward violent crime or sex offenses.
See Cluff,
The disparity between Gonzales’s technical violation of a regulatory crime of omission and the 28 years to life sentence imposed is so extreme that the state court could uphold the constitutionality of the sentence only by reading the “grossly disproportionate” standard out of federal law. The court in
Carmony
concluded that “[i]t is beyond dispute that a life sentence is grossly disproportionate to the[teehnical failure to register].”

Notes
. The provisions of California Penal Code § 290 have since been recodified to California Penal Code § 290.012. In this opinion, we use the section numbers and statutory language corresponding to the charged crimes when Gonzalez was sentenced.
.
See People v. Superior Court (Romero),
. The 1989 lewd act and attempted rape convictions arose from a single incident.
. Under the Three Strikes law, a defendant with a current felony conviction and no fewer than two prior serious or violent felony convictions must be sentenced to an indeterminate period of life imprisonment, with the minimum term calculated as the greater of three times the punishment for each current felony conviction, or 25 years. Cal.Penal Code §§ 667(e)(2)(A) & 1170.12(c)(2)(A).
. Under California Penal Code § 667.5(b), a defendant convicted of a felony receives a one-year enhancement for each prior separate prison term served for any felony, “provided that no additional term shall be imposed ... for any prison term served prior to a period of five years in which the defendant remained free of both prison custody and the commission of an offense which results in a felony conviction.”
. Gonzalez raises two uncertified issues in his opening brief, which we construe as a motion to expand the Certificate of Appealability. See 9th Cir. R. 22-l(e). Because Gonzalez failed to make "a substantial showing of the denial of a constitutional right” with respect to those issues, we deny that motion. See 28 U.S.C. § 2253(c)(2).
. Justices Scalia and Thomas, concurring only in the judgment, concluded that the Eighth Amendment contains no proportionality principle at all.
Id.
at 31-32,
. We recognize that administrative efficiency requires California to designate some benchmark, such as the registrant’s birthday, for the annual registration requirement and that California has a legitimate interest in criminalizing failure to comply with that regulatory requirement. Our analysis in no way calls into question the constitutional validity of § 290(a)(1)(D) or California’s ability to criminalize its violation. We evaluate the social justification for the requirement only to determine whether the Three Strikes sentence imposed in Gonzalez's case exceeds constitutional limits.
. We note that for purposes of sentencing, the trial court in
Meeks
struck the defendant's prior convictions with respect to his conviction for his failure to register annually within five days of his birthday.
See 20
Cal.Rptr.3d at 448.
Meeks
is consistent with
Cluff,
which held that the trial court abused its discretion by denying a
Romero
motion to strike one or more priors in the interest of justice when sentencing the defendant for failure to register annually within five days of his birthday.
See Cluff,
. We note that the
Carmony
court's analysis of that provision comports with common sense, particularly as applied to the circumstances of this case. To convict Gonzalez of violating § 290(a)(1)(D), the jury found “beyond a reasonable doubt that the defendant had actual knowledge of his duty to register annually within five working days of his birthday and that he knew what act was required to be performed.”
See People v. Garcia,
. Gonzalez’s sentence is also a high multiple of the plea offers he received.
See Reyes v. Brown,
.
See, e.g., Rummel,
. In fact in
Carmony,
the court found that "[the defendant’s] failure to register was completely harmless and no worse than a breach of an overtime parking ordinance,”
