Background
In 1986, a jury convicted Harold Lee Harvey, Jr. of two counts of first-degree murder in Okeechobee County, Florida. The jury recommended death by an 11-1 vote, and the trial court imposed death sentences on both counts after finding four aggravating factors — that the murders were committed during a robbery or burglary, to avoid lawful arrest, in a cold and calculated manner, and in an especially heinous, atrocious, and cruel way. Harvey’s convictions and sentences survived direct appeal and numerous subsequent challenges in both state and federal courts over more than three decades.
Harvey filed his third successive motion for postconviction relief under Florida Rule of Criminal Procedure 3.851, arguing that newly discovered evidence entitled him to a new trial or new penalty phase. He contended that a 2022 resolution by the American Psychological Association (APA) — calling on courts and legislatures to ban the death penalty for defendants under age twenty-one — along with 2023 expert reports by two neuroscientists, established that his brain was not fully developed at the time of the crimes. Harvey was twenty-two years old when he committed the murders. Neither expert physically examined Harvey; both reviewed records and opined that his brain was still maturing at the time of the crimes.
The postconviction court held a case management conference and summarily denied Harvey’s motion, finding he failed to overcome the timeliness and procedural bars applicable to successive motions and that his claims were meritless because no court had extended the death-penalty ban beyond defendants who are under eighteen or intellectually disabled. Harvey timely appealed to the Florida Supreme Court.
The Court’s Holding
The Florida Supreme Court unanimously affirmed the summary denial of Harvey’s third successive postconviction motion. The court held that Harvey’s claims were either procedurally barred or meritless. Because Harvey’s sentences became final in 1989, his motion fell well outside Rule 3.851’s one-year filing deadline, and he failed to demonstrate that the newly discovered evidence exception applied. The court reaffirmed its prior precedent that professional resolutions, consensus opinions, and scientific articles do not constitute “newly discovered evidence,” applying that rule to the 2022 APA resolution just as it had in Barwick v. State.
The court further held that the expert reports of Dr. Somerville and Dr. Merikangas likewise did not qualify as newly discovered evidence. Neither expert had evaluated Harvey personally, and their opinions — based on a review of existing records and general brain-development research — amounted to new interpretations of previously known facts rather than genuinely new evidence. The court stressed that obtaining a new expert to review the same records does not create newly discovered evidence.
Harvey’s cumulative error argument failed for the same reasons: because all underlying claims were either procedurally barred or without merit, there was no basis for a cumulative error finding. Additional trial-related claims Harvey raised — including the voluntariness of his Miranda waiver, his mens rea, and the weighing of sentencing factors — either were or could have been raised on direct appeal and were not cognizable in collateral proceedings.
Key Takeaways
- The Florida Supreme Court reaffirmed that professional resolutions, scientific consensus statements, and expert reports synthesizing existing research do not constitute “newly discovered evidence” sufficient to overcome procedural bars in successive postconviction motions.
- An expert report prepared by a neuroscientist who never examined the defendant and merely applies general brain-development literature to existing case records does not create newly discovered evidence under Florida law.
- Neither Florida nor federal constitutional law currently bars execution of defendants who were eighteen or older at the time of their crimes solely on the basis of continued brain development or a “mental age” below eighteen — absent a recognized intellectual disability.
- Claims that could have been raised on direct appeal, including cumulative trial error, are procedurally barred in collateral postconviction proceedings and cannot be revived by framing them as components of a newly discovered evidence claim.
Why It Matters
This decision is the latest in a series of Florida Supreme Court rulings rejecting attempts to extend Eighth Amendment categorical death-penalty bars — currently limited to juveniles under eighteen and the intellectually disabled — to young adults based on neuroscientific evidence of incomplete brain development. Defense advocates have increasingly relied on the 2022 APA resolution and similar scientific consensus statements to argue for a higher age threshold, but Florida courts have consistently held that such materials do not meet the legal definition of newly discovered evidence and do not reflect a new constitutional rule.
The ruling signals that any expansion of the categorical bar to defendants who were eighteen or older at the time of their offense would require action by the U.S. Supreme Court, not state postconviction courts. Capital defense practitioners should take note that neuroscientific opinions prepared without a direct examination of the defendant, and grounded in general developmental literature rather than case-specific findings, are unlikely to clear the procedural and substantive hurdles required to support successive postconviction relief in Florida.
