concurring in part and dissenting in part.
While I agree with the majority’s conclusion that Gaskin’s claim of improper doubling is untimely and procedurally barred, I write separately to express my disagreement with denying Gaskin relief under Hurst v. Florida1 and Hurst.2 As I stated in my concurring in part and dissenting in part opinion in Asay,3 fundamental fairness concerns emanating from the constitutional rights at stake require us to hold Hurst fully retroactive to all death sentences imposed under Florida’s prior,, unconstitutional capital sentencing scheme. Asay, 210 So.3d at 32, 2016 WL 7406538 (Fla. Dec. 22, 2016) (Pariente, J., concurring in part and dissenting in part); see Hurst v. Florida, 136 S.Ct. at 622 (holding;Floridá’s' capi*402tal sentencing scheme unconstitutional). Thus, I would hold that Hurst applies retroactively to Gaskin. Further determining that the Hurst error in Gaskin’s sentence was not harmless beyond a reasonable doubt, I would grant Gaskin a new penalty phase.
Short of holding Hurst fully retroactive, I would at least apply Hurst to Gaskin because he, through his attorneys, challenged the constitutionality of Florida’s capital sentencing statute at trial in 1990 and, again, on direct appeal in 1991. This Court summarily rejected Gaskin’s claim on direct appeal, stating: “We also reject without discussion Gaskin’s multiple assertions regarding the constitutionality of the capital-sentencing statute as each of his arguments has previously been decided adversely to his position.” Gaskin v. State, 591 So.2d 917, 920 (Fla. 1991). Although our opinion did not detail Gaskin’s constitutional challenges, the record on appeal reveals that Gaskin argued that “section 921.141 ... was unconstitutional on its face” for the reasons espoused by the United States Supreme Court in Ring4 and Hurst v. Florida and then further explained by this Court in Hurst:
[Bjefore a sentence of death may be considered by the trial court in Florida, the jury must find the existence of the aggravating factors proven beyond a reasonable doubt, that the aggravating factors are sufficient to impose death, and that the aggravating factors outweigh the mitigating circumstances.
These same requirements existed in Florida law when Hurst was sentenced in 2012—although they were consigned to the trial judge to make.
We also conclude that, just as elements of a crime must be found unanimously by a Florida jury, all these findings necessary for the jury to essentially convict a defendant of capital murder— thus allowing imposition of the death penalty—are also elements that must be found unanimously by the jury. Thus, we hold that in addition to unanimously finding the existence of any aggravating factor, the jury must also unanimously find that the aggravating factors are sufficient for the imposition of death and unanimously, find that the aggravating factors outweigh the mitigation before a sentence of death may be considered by the judge.
Hurst, 202 So.3d at 53-54 (footnotes omitted).
Amid a myriad of arguments as to how Florida’s capital sentencing scheme violated the fundamental rights of defendants facing the death penalty in Florida, Gaskin specifically argued that the statute “does not require a sentencing recommendation by a unanimous jury or a substantial majority of the jury and thus results in the arbitrary and unreliable application of the death sentence and denies the right to a jury and to due process of law.”5 Among Gaskin’s several motions, filed through counsel,6 disputing the validity of Florida’s *403capital sentencing scheme was a “Motion for Use of Special Verdict Form for the Unanimous Jury Determination of Statutory Aggravating Circumstances,” citing among other constitutional bases the Sixth Amendment to the United States Constitution and article I, section 22, of the Florida Constitution. State v. Gaskin, No. 90-01/07/17 (Fla. May 10, 1990). Gaskin also filed a separate motion to declare unconstitutional section 921.141, Florida Statutes, broadly arguing many of the deficiencies in the statute that have now been recognized as constitutionally impermissible, such as jury overrides and the bare majority jury recommendation.7 Most closely resembling Hurst v. Florida and Hurst, Gaskin argued that section 921.141 is facially unconstitutional because the “jury recommendation need not be unanimous,” nothing “require[s] the court to instruct the jury that to return a recommendation of death, the jury must be convinced beyond every reasonable doubt that the aggravating circumstances outweigh the mitigating circumstances,” “the jury is not required to list the specific aggravating circumstances they have found beyond a reasonable doubt when they recommend the death penalty,” and “it permits the trial judge to consider aggravating circumstances in imposing the death sentence that the advisory jury may not have considered or that the advisory jury may have rejected.” Id at 7-9.8 Even without a finding a full retro-activity, under Justice Lewis’s concurring in result opinion in Asay, Hurst would apply retroactively to Gaskin under James v. State, 615 So.2d 668 (Fla. 1993), because Gaskin asserted, presented, and preserved a challenge to the lack of jury factfinding in Florida’s capital sentencing procedure. Asay, 210 So.3d at 30, 2016 WL 7406538, at *20 (Lewis, J., concurring in result).
Because I would apply Hurst to Gaskin’s case, I must now determine whether the Hurst error in Gaskin’s penalty phase was harmless beyond a reasonable doubt. On remand from the United States Supreme Court, this Court determined that Hurst error is capable of harmless error review. Hurst, 202 So.3d at 67. In Hurst, we established the test for reviewing these errors for harmlessness:
Where the error concerns sentencing, the error is harmless only if there is no reasonable possibility that the error contributed to the sentence. See, e.g., Zack v. State, 753 So.2d 9, 20 (Fla. 2000). Although the harmless error test applies to both constitutional errors and errors not based on constitutional grounds, “the harmless error test is to be rigorously applied,” [State v.] DiGuilio, 491 So.2d [1129,] 1137 [Fla. 1986], and the State bears an extremely heavy burden in cases involving constitutional error. Therefore, in the context of a Hurst v. Florida error, the burden is on the *404State, as the beneficiary of the error, to prove beyond a reasonable doubt that the jury’s failure to unanimously find all the facts 'necessary for imposition of the death penalty did not contribute- to •Hurst’s death sentence in this case. We reiterate:
The' test is not a sufficiency-of-the-evidence, a correct result, a not clearly wrong, a substantial evidence, a more probable than not, a clear and convincing, or even an overwhelming evidence test. Harmless error is not a device for the appellate court to substitute itself for the trier-of-fact by simply weighing the evidence. The focus is on the effect of the error on the trier-of-fact.
DiGuilio, 491 So.2d at 1139. “The question is whether there is a reasonable possibility that the error affected the [sentence].” Id.
202 So.3d at 68 (last alteration in original). As applied to the right to a jury trial with regard to the facts necessary to impose the death penalty, it must be clear beyond a reasonable doubt that a rational jury would have unanimously found that there were sufficient aggravating factors that outweighed the mitigating circumstances.
Gaskin’s sentences became final in 1993. Majority op. at 400. The penalty phase jury voted eight to four to recommend a sentence of death for both murders. Majority op. at 400. So not only are we unable to determine beyond a reasonable doubt that the jury unanimously made the requisite findings to impose death as required by Hurst, but most significantly in Gas-kin’s case, the jury may have relied on invalid aggravating factors to reach its mere eight - to four recommendation for death. See majority op. at 400. As • the majority explained, this Court reversed and vacated Gaskin’s sentences of felony murder, which the sentencing jury.likely considered in its weighing process. Majority op. at 400. Thus, for the reasons stated above and under the test set forth by this Court in Hurst for determining whether Hurst errors are harmless beyond a reasonable doubt, I would conclude that any error in Gaskin’s nonunanimous sentencing recommendation was not harmless beyond a reasonable ■ doubt and Gaskin should, therefore, receive a new penalty phase under Hurst.
