The issue in this case is whether a 30-year prison sentence for a nonhomicide offense committed when appellant was a juvenile violates the Eighth Amendment or Graham v. Florida , 560 U.S. 48, 130 S.Ct. 2011, 176 L.Ed.2d 825 (2010). Because we cannot conclude that the sentence violates the United States Constitution, we affirm.
In 1997, appellant entered an open plea to the following offenses committed when he was 16 years old: burglary of a dwelling while armed with a firearm (count I), robbery with a firearm (counts II-VI), and attempted robbery with a firearm (count VII). The trial court sentenced him to concurrent terms of 30 years in prison for counts I through VI and 15 years for count VII.
In 2002, appellant moved to correct his sentence based upon Heggs v. State , 759 So.2d 620 (Fla. 2000). The state conceded there was a Heggs violation. With a corrected scoresheet, appellant's maximum permissible sentence was 21.42 years in prison. The trial court resentenced appellant *418on counts II-VI to 20 years in prison. He was not resentenced on count I and is still serving 30 years for that offense. It is unclear from the record on appeal in this case why appellant was not resentenced on count I.
In April 2017, appellant filed the instant rule 3.800(a) motion seeking resentencing pursuant to Graham , Henry v. State , 175 So.3d 675 (Fla. 2015), and Kelsey v. State , 206 So.3d 5 (Fla. 2016). Appellant argued that the trial court must reconsider his sentence in light of the factors enumerated in section 921.1401(2), Florida Statutes (enacted as part of chapter 2014-220).
The trial court set the case for resentencing. Prior to the hearing, defense counsel filed memoranda of law explaining that appellant was entitled to resentencing under the 1994 guidelines. Counsel argued that the most appellant could receive was 21.42 years in prison and the court could not impose an upward departure without violating Apprendi v. New Jersey , 530 U.S. 466, 120 S.Ct. 2348, 147 L.Ed.2d 435 (2000), and Blakely v. Washington , 542 U.S. 296, 124 S.Ct. 2531, 159 L.Ed.2d 403 (2004). At the time, appellant had served over 20 years in prison.
The trial court requested additional briefing as to whether resentencing was required, and the parties filed additional memoranda. Discussing the Florida Supreme Court's decisions in Kelsey , Henry , and Johnson v. State , 215 So.3d 1237 (Fla. 2017), the defense argued that any term-of-year sentences for juvenile offenders without review provisions are illegal. The state asserted that appellant's sentence did not constitute a Graham violation and chapter 2014-220 comes into play only if resentencing is required.
The trial court denied appellant's motion based in part upon this court's decision in Davis v. State , 199 So.3d 546 (Fla. 4th DCA 2016), which involved a 75-year sentence challenged in a motion for postconviction relief. In its ruling, the trial court stressed that Kelsey and Johnson were cases where the original life without parole sentence for non-homicide offenses clearly violated Graham . The court concluded:
While the Court does not believe that the Supreme Court has yet to mandate resentencing of all juveniles sentenced to a term of years without a review mechanism, this issue is ripe for appellate guidance. Certainly there is considerable confusion surrounding the status of juvenile offenders whose original sentences did not violate Graham .
While this appeal was pending, the Florida Supreme Court quashed this court's decision in Davis and remanded for resentencing in light of the decision in Johnson . Davis v. State , SC16-1905, 2018 WL 480516 (Fla. Jan. 19, 2018).
In Graham , the United States Supreme Court held that the Eighth Amendment prohibits a non-homicide juvenile offender from receiving a sentence of life without parole unless there is "some meaningful opportunity to obtain release based on demonstrated maturity and rehabilitation." 560 U.S. at 75, 130 S.Ct. 2011. In response to Graham , the Florida Legislature enacted chapter 2014-220, Laws of Florida, which has been codified in sections 775.082, 921.1401, and 921.1402, Florida Statutes. Chapter 2014-220 requires that juvenile offenders who commit offenses after July 1, 2014 receive a review hearing and an opportunity for early release after serving 15, 20, or 25 years depending on the crime committed and the length of the prison sentence.
Subsequently, the Florida Supreme Court decided Henry , Kelsey , Johnson , and Lee v. State , 234 So.3d 562 (Fla. 2018). In Henry , a juvenile non-homicide offender who was sentenced to life plus 60 years *419was resentenced following Graham to an aggregate of 90 years. 175 So.3d at 676. Citing Graham , the supreme court found the new sentence unconstitutional and remanded for resentencing under chapter 2014-220. Id. at 679-80.
In Kelsey , a juvenile non-homicide offender who was sentenced to life plus 25 years was resentenced to 45 years after Graham but before the Florida Legislature passed chapter 2014-220. 206 So.3d at 6-7. The supreme court clarified that a term-of-years sentence does not have to amount to a de facto life sentence to violate Graham . Id. at 10. The court further stated that "juveniles who are serving lengthy sentences are entitled to periodic judicial review to determine whether they can demonstrate maturation and rehabilitation." Id. The court concluded that the 45-year resentence did not provide a meaningful opportunity for relief within his lifetime and remanded for resentencing under chapter 2014-220. Id. at 11.
In Johnson , a juvenile non-homicide offender who was sentenced to life was resentenced following Graham to 100 years. 215 So.3d at 1239. The supreme court stated that "we have determined that Graham prohibits juvenile nonhomicide offenders from serving lengthy terms of incarceration without any form of judicial review mechanism." Id. at 1240. Because the sentence violated Graham , the court remanded for resentencing under chapter 2014-220. Id. at 1243-44.
In Lee , a juvenile non-homicide offender who was sentenced to life was resentenced to 40 years after the decision in Graham but before the Florida Legislature passed chapter 2014-220. 234 So.3d at 563-64. The supreme court reversed and remanded for resentencing under chapter 2014-220, finding the sentence did not "provide him an opportunity to obtain early release based on a demonstration of maturity and rehabilitation before the expiration of the imposed term." Id. at 564.1
We distinguish Henry , Kelsey , Johnson , and Lee , as those cases all involve juvenile non-homicide offenders who were resentenced following Graham and whose sentences imposed on resentencing still were unconstitutional. In those cases, the violation of the dictates of Graham resulted in resentencing, which was mandated by the Florida Supreme Court to be in accordance with chapter 2014-220. In contrast, the instant case involves an original sentence, and there is no clear authority stating that a 30-year sentence violates Graham so as to trigger resentencing under chapter 2014-220. The dissent overlooks this distinction and, in doing so, conflates Graham and chapter 2014-220.
Certainly considerable confusion remains as to when a juvenile nonhomicide offender sentence becomes illegal under Graham so as to mandate resentencing. In other words, it is unclear whether the triggering factor is a per se "lengthy" sentence, a sentence that exceeds the statutory threshold of chapter 2014-220, or just any "term-of-years" sentence. Despite this confusion, what is clear is that the Florida Supreme Court has not plainly required that all "term-of-years" juvenile offender sentences-even those of shorter duration-provide a mechanism for early release based on demonstrated maturity and rehabilitation. Nor has the supreme court expressly stated that any juvenile offender sentence exceeding the thresholds for review *420in chapter 2014-220 is unconstitutional or otherwise illegal.
The Florida Supreme Court has not yet applied Graham to a 30-year or shorter sentence. In Abrakata v. State , 168 So.3d 251 (Fla. 1st DCA 2015), a juvenile offender who received a 25-year sentence for nonhomicide offenses argued that his sentence violated Graham and that he was entitled to review under section 921.1402(2)(c). The First District concluded that the sentence did not violate Graham and without a Graham violation, section 921.1402 did not apply retroactively. Id. at 252. The supreme court declined review. See SC15-1325, 2017 WL 24657 (Fla. Jan. 3, 2017) (Pariente, J., dissenting). See also Hill v. State , 172 So.3d 491 (Fla. 1st DCA 2015), rev. denied , SC15-1667, 2017 WL 24659 (Fla. Jan. 3, 2017) (Pariente, J., dissenting) (involving a 35-year sentence for nonhomicide offenses); McCullum v. State , 173 So.3d 1056 (Fla. 1st DCA 2015), rev. denied , SC15-1770, 2017 WL 24756 (Fla. Jan. 3, 2017) (Pariente, J., dissenting) (involving an aggregate 55-year sentence for nonhomicide offenses); Williams v. State , SC16-2170, --- So.3d ----, 2018 WL 1870518 (Fla. Apr. 19, 2018) (involving a plurality opinion which, based entirely on the state's concession, ended inquiry and remanded for resentencing of a 35-year sentence pursuant to chapter 2014-220).
Further, no decision from the Supreme Court of the United States has expanded Graham so broadly that it would encompass a 30-year sentence. See, e.g., Virginia v. LeBlanc , --- U.S. ----, 137 S.Ct. 1726, 1729, 198 L.Ed.2d 186 (2017) (holding that it was not objectively unreasonable for a Virginia state court to conclude that Virginia's geriatric release program, which employed normal parole factors and allowed for conditional release after a defendant reaches age 60 or 65, "satisfied Graham 's requirement that juveniles convicted of a nonhomicide crime have a meaningful opportunity to receive parole").
Our court has also previously declined to find that a 31-year sentence imposed for crimes committed prior to the enactment of chapter 2014-220 requires resentencing. See Tillman v. State , --- So.3d ----, 42 Fla. L. Weekly D1844 (Fla. 4th DCA Aug. 23, 2017) ; see also Davis v. State , 214 So.3d 799 (Fla. 1st DCA 2017) (concluding that a juvenile offender's 35-year sentence for homicide and non-homicide offenses did not violate Graham or Miller v. Alabama , 567 U.S. 460, 132 S.Ct. 2455, 183 L.Ed.2d 407 (2012), so resentencing was not required).
There is simply no authority-either constitutional, statutory, or precedential-stating that any "term-of-years" juvenile offender sentence that does not provide an opportunity for early release, or any sentence exceeding the statutory thresholds in chapter 2014-220, is unconstitutional under Graham and requires resentencing even if the offense was committed prior to chapter 2014-220's effective date. In the absence of a Graham violation, there is no clear authority to resentence. To hold otherwise would effectively require resentencing in every "term-of-years" case or every case where the sentence exceeds the statutory thresholds, no matter when the crime was committed.
In order for a mandated resentencing under chapter 2014-220 to come into play, there must first be a Graham violation. Without a clear violation of Graham , there is no requirement for a resentencing under chapter 2014-220.
Significantly, the prohibition against cruel and unusual punishment in the Florida Constitution must be construed in conformity with decisions of the Supreme Court of the United States interpreting the Eighth Amendment. Art. I, § 17, Fla. Const.;
*421Correll v. State , 184 So.3d 478, 489 (Fla. 2015) ("[T]his Court is bound by the conformity clause of the Florida Constitution to construe the state prohibition against cruel and unusual punishment consistently with pronouncements by the United States Supreme Court."). Thus, we decline to expand the holding of Graham .
Appellant did not receive a life without parole sentence and, even if he serves his 30-year sentence day-for-day, he will be released when he is in his forties. Given these circumstances, we cannot conclude that the 30-year sentence violates the Eighth Amendment or Graham , especially in the absence of any authority to the contrary.
We affirm the trial court's order and certify conflict with the following decisions: Cuevas v. State , 241 So.3d 947 (Fla. Mar. 9, 2018) (reversing the denial of a rule 3.800(a) motion and concluding that a juvenile non-homicide offender's sentences of 26 years in prison were unconstitutional under Graham as construed in Henry and Johnson ); Blount v. State , 238 So.3d 913 (Fla. 2d DCA 2018) (reversing the denial of a rule 3.800(a) motion to correct juvenile nonhomicide sentences of 40 years in prison and remanding for resentencing pursuant to Johnson ); Mosier v. State , 235 So.3d 957 (Fla. 2d DCA 2017) (reversing the denial of a rule 3.800(a) motion and concluding that a juvenile non-homicide offender's sentences of 30 years in prison followed by 10 years of sexual offender probation were unconstitutional under Graham as construed in Henry and Johnson ); Alfaro v. State , 233 So.3d 515, 516 (Fla. 2d DCA 2017) (reversing 30-year sentences for nonhomicide offenses and rejecting trial court's conclusion that " Kelsey only applied to juvenile offenders like Kelsey who initially received life sentences but had been resentenced to a term of years under Graham "); Burrows v. State , 219 So.3d 910, 911 (Fla. 5th DCA 2017) (reversing denial of postconviction relief and remanding for resentencing where juvenile offender received 25-year sentences for non-homicide offenses).
Our affirmance is without prejudice to appellant filing a rule 3.800(a) motion to correct an illegal sentence if the sentence on count I violates Heggs and the failure to correct the sentence was an oversight or error.
Affirmed. Conflict certified .
