Introduction

Contrary to what many commentators have suggested about Hall v. Florida,¹ the case’s constitutional legacy will not be its modest step to protect criminal defendants with intellectual disabilities. Rather, what will stand out years from now is how Hall quietly but fundamentally transformed both the understanding of when it is appropriate for the U.S. Supreme Court to search for a national consensus on an issue under the Eighth Amendment and how the Court determines whether a consensus exists.

The Court’s recent decision in Hall will help ensure that states meaningfully enforce² the protection the Court originally set forth in Atkins v. Virginia,³ which held that individuals with intellectual disabilities cannot be executed. The immediate responses to the Hall decision characterized it primarily as a “small but meaningful step”⁴ to “chip away at the death penalty.”⁵ But the majority opinion’s reliance on the views and practices of medical experts and psychiatric professionals has overshadowed other important doctrinal developments.⁶ This Essay represents an early effort to identify those developments and explore their implications.

This Essay contains three Parts. After describing the Court’s narrow holding briefly in Part I, this Essay explores Hall’s two most remarkable aspects. Part II explicates how the Supreme Court’s decision to answer the question Hall presented by engaging in the Eighth Amendment national consensus analysis is doctrinally surprising and significant. Part III examines how the Court’s approach to conducting that consensus analysis deepens the Court’s commitment to an increasingly sophisticated method. This Essay takes the position that the Court’s deployment of its consensus-detecting apparatus is not only unexpected in the Hall context but is also striking because it could implicate a broad range of issues related to constitutional claims against harsh punishments like the death penalty. And this Essay further observes that the manner in which the Hall Court determined that a national consensus existed reflects an evolving and more nuanced Eighth Amendment approach that the Court continues to refine.⁷ Ultimately, this Essay predicts that Hall’s long-term significance will reach far beyond its narrow yet important holding.

I. Hall v. Florida: The Holding

In Hall, an inmate challenged his death sentence on the grounds that he had an intellectual disability⁸ and was therefore exempt from capital punishment under Atkins. The inmate, Mr. Hall, was tried and sentenced to death before the U.S. Supreme Court decided Atkins. He had nevertheless presented evidence of his intellectual disability, and the trial court that sentenced him had “found that there was ‘substantial evidence in the record’ to support the finding that ‘Freddie Lee Hall ha[d] been mentally retarded his entire life.’”⁹ After the Supreme Court decided Atkins, Mr. Hall relied on that substantial evidence and the trial court’s remarkable finding to argue that he should not be executed.¹⁰ But the Florida Supreme Court rejected Mr. Hall’s argument because he had not provided admissible evidence to demonstrate that he had an IQ of seventy or below.¹¹ The State successfully argued “Florida law requires that, as a threshold matter, Hall show an IQ test score of 70 or below before presenting any additional evidence of his intellectual disability.”¹²

The Florida Supreme Court’s ruling relied on two ambiguities embedded in Atkins: first, that it “did not provide definitive procedural or substantive guides for determining when a person who claims mental retardation” qualifies for the Eighth Amendment protection;¹³ and second, that it “le[ft] to the States the task of developing appropriate ways to enforce the constitutional restriction.”¹⁴ Atkins did not set out a clear definition of intellectual disability to which the states would be held accountable, and it granted the states significant leeway in devising mechanisms to enforce the Court’s holding.

Because one criterion of intellectual disability is “significantly subaverage intellectual functioning,” an individual’s performance on an IQ test constitutes critical evidence.¹⁵ Under the relevant Florida statute (and general professional practice), an IQ score of approximately seventy or below would meet this particular criterion. But the Florida Supreme Court’s decision to make this score of seventy a “mandatory cutoff”¹⁶ was problematic for two key reasons: first, it disregarded the standard error of measurement that experts in the field universally recognize;¹⁷ and second, it precluded the consideration of evidence related to other criteria—specifically “evidence . . . [of] the defendant’s failure or inability to adapt to his social and cultural environment”—that professionals rely on to diagnose intellectual disability even in some cases when an individual scores higher than seventy on an IQ test.¹⁸

Confronted with these concerns about Florida’s restrictive approach to recognizing an individual’s intellectual disability when seeking execution, the U.S. Supreme Court struck down Florida’s rule. According to the Court, “Freddie Lee Hall may or may not be intellectually disabled, but the law requires that he have the opportunity to present evidence of his intellectual disability, including deficits in adaptive functioning over his lifetime.”¹⁹ Put simply, “when a defendant’s IQ falls within the margin of error for intellectual disability, he or she must be able to present other evidence about problems adapting.”²⁰

Although an undeniably important opinion, Hall’s immediate reach remains unknown. One commentator observed: “While it is too soon to know how broad Hall’s practical effect will be . . . [the early] estimates suggest that only a tiny fraction of America’s approximately 3,000 death row inmates are likely to be exempted from the death penalty because of Hall.”²¹

Whatever one makes of the Court’s holding in Hall, it is critical to step back to look at how the Court reached its conclusion to understand the decision’s potential jurisprudential ramifications.

II. Why Did the Court Conduct an Eighth Amendment Consensus Analysis?

A. Background on the Court’s Eighth Amendment Consensus Analysis

In reaching the conclusion that Florida’s rule was unconstitutional, the Supreme Court in Hall relied on a two-part Eighth Amendment analysis, which entails both a search for a national consensus against a punishment and the Court’s application of its independent judgment.²² To explore why this was a surprising move by the Court, a brief overview of that analysis will set a helpful backdrop.²³

The Court has long held that “[t]he [Eighth] Amendment must draw its meaning from the evolving standards of decency that mark the progress of a maturing society.”²⁴ To determine the substance of those standards of decency:

Courts employ this Eighth Amendment approach when evaluating a statutory punishment’s constitutionality as applied either to a particular criminal offense or a particular class of offenders. When the Court has found that the challenged punishments are unconstitutional, it has imposed a “categorical bar”²⁶ that exempts individuals convicted of certain crimes²⁷ or belonging to a particular class of offenders²⁸ from execution. The objective indicia analysis reflects that the Court is evaluating the punishment itself—several of the objective factors gauge on the ground sentencing outcomes and the punishment’s legal and practical availability. Hall, however, did not fall within the traditional ambit of this approach. Hall did not present a question about the constitutionality of a statutorily authorized punishment. Instead, it asked the Court to determine whether a state’s method of enforcing the mandate in Atkins violated the U.S. Constitution.²⁹ This enforcement issue—the process by which the state sought to protect a class of offenders already granted Eighth Amendment protection—is distinct from all the seminal consensus cases.

B. What the Court Did in Hall

Early in the opinion, the Court explained how it would answer the question Hall presented. According to the Court:

After exploring how medical professionals define and diagnose intellectual disability, the Court assessed how the states had implemented Atkins. It conducted a headcounting analysis (similar but different in important respects to consensus analyses done in other cases)³¹ and determined that “at most nine States mandate a strict IQ score cutoff at 70.”³² The Court contrasted this number with the forty-one states where a defendant in Mr. Hall’s position “would not be deemed automatically eligible for the death penalty.”³³ Drawing on this number of states that had not adopted Florida’s IQ cutoff and the growing recognition that IQ tests entail a standard error of measurement, the Court concluded that there was a consensus against a strict IQ cutoff of seventy. The Court then exercised its independent judgment and found that the Florida rule was unconstitutional.³⁴

C. Why the Court’s Analysis is Surprising

The Eighth Amendment approach that the Court employed in deciding Hall was not the obvious analytical framework. Had it been, one or both of the parties might have meaningfully utilized it. But neither party’s petition stage briefs contained a consensus claim, and the State’s brief on the merits pointed out that Petitioner Hall did not argue that a consensus against IQ score cutoffs exists.³⁵ Indeed, in his Reply Brief on the merits, Mr. Hall argued, “[W]hile Florida is in a distinct and small minority . . . the precise number of States that share Florida’s approach is immaterial. Atkins recognized the relevant national consensus, and the question here is only whether Florida’s rule complies with Atkins. It does not.”³⁶ The dissenting opinion in Hall picked up on this, remarking “[i]t is telling that Hall himself does not rely on a consensus among States.”³⁷

The parties did not contemplate this case to present a traditional consensus question, demonstrating that the Court’s analysis was unexpected. The amici did not meaningfully fill the void left by the parties’ briefs either. Although seven amicus briefs were filed,³⁸ only one set forth a consensus analysis.³⁹ While that lone brief may have assisted the Court’s framing of the issue, it did not persuade the Court on the consensus analysis’s substance because the amicus argued that there was no consensus against the Florida rule. Of course, the Court’s majority found the contrary.

What makes the Court’s approach even more surprising is that despite the parties’ decision not to present the Eighth Amendment consensus concern, not a single justice took the position that a consensus analysis was unnecessary or inappropriate. The four dissenting justices disagreed with the way in which the majority conducted its consensus analysis, but they did not argue that the consensus framework itself was the wrong one for deciding the question.⁴⁰ Thus, all nine Supreme Court justices endorsed the view that the Hall litigation required a search for “methodological consensus.”⁴¹ In this way, Hall marks a potentially significant expansion of the Eighth Amendment’s reach. Now, not only will the Court look to states’ legislative determinations about what punishments are available for particular crimes and the actual sentencing practices but it may also consider the method by which the jurisdictions impose those punishments to see if there are consensuses around those procedural practices.

D. Why the Court’s Analysis is Critical: the Implications

The Court’s Eighth Amendment approach in Hall allows litigants to present new constitutional challenges to outdated or outlier methodologies that states utilize to implement harsh punishments like the death penalty. As a starting point, it is easy to envision a few examples (like Hall) that raise issues with the way in which states have implemented Atkins. In one high-profile Atkins case, a defendant named Warren Hill repeatedly challenged the state of Georgia’s statutory allocation of the burden of proof for those claiming that their intellectual disability prohibits their execution.⁴² Georgia requires defendants to prove their intellectual disability to the fact finder beyond a reasonable doubt in order to prevail on an Atkins claim.⁴³ Eleventh Circuit Judge Barkett notes “Georgia is the only state to require proof of mental retardation beyond a reasonable doubt.”⁴⁴ Like Florida’s IQ cutoff, Georgia’s method of enforcing Atkins appears out of step with the rest of the nation.⁴⁵ A consensus-based challenge, seemingly tenuous from a doctrinal perspective before Hall, may now be a potent approach to striking down this draconian statute. Given that states have found a variety of ways to water down Atkins,⁴⁶ a number of similar challenges grounded in consensus may be ripe.⁴⁷

But there is no doctrinal reason the Hall approach should be cabined to intellectual disability claims. Other outlier practices surrounding the death penalty may be challenged as well. While nearly all states that administer the death penalty require jurors to decide whether a guilty inmate will receive a life sentence or the death penalty, three states permit trial court judges to override jurors’ sentencing determinations: Delaware, Florida, and Alabama.⁴⁸ Last year, attorneys for an Alabama death row inmate filed a petition for certiorari to the U.S. Supreme Court asking if the “increasingly rare and geographically isolated practice of imposing the death penalty through override violate[s] the nation’s evolving standards of decency and the Eighth Amendment?”⁴⁹ The Supreme Court denied the petition, but Justice Sotomayor wrote a dissent from the denial of certiorari in Woodward v. Alabama.⁵⁰ Part II of her dissent looks like a consensus analysis. She observed that only three states authorize judicial override and emphasized the infrequency of the life to death overrides in Florida and Delaware before concluding “Alabama has become a clear outlier.”⁵¹ Interestingly, Justice Sotomayor found that the practice may contravene Eighth Amendment principles, but she did not cite to the consensus cases. In light of Hall, those cases take on renewed relevance, and the question originally presented in Woodward seems ripe for review.

Countless other issues can be viewed and litigated through the consensus framework if the Court adheres consistently to the principle that evolving standards of decency govern not only what punishments are constitutionally prohibited but also the procedures by which those punishments are imposed.⁵² Assuming this consistent application, some challenges to the way in which jurisdictions impose the death penalty could find fertile ground in Hall.⁵³ One question is what other punishments, aside from capital punishment, will also be susceptible to Hall-style litigation. Although the Court has not often utilized a consensus analysis outside the death penalty context, it recently found a consensus against life without parole sentences for juvenile offenders convicted of nonhomicide crimes.⁵⁴ The Court’s involvement in policing the harshest punishments available to certain classes of offenders suggests that juveniles facing life or life equivalent sentences may successfully persuade the Court to strike outlier policies and practices governing their punishments.⁵⁵ Whether the Court will evaluate other punishments or the practices implicating them is an open question.⁵⁶

III. How the Court Conducted its Eighth Amendment Consensus Analysis

Hall not only extends the consensus analysis’s reach, but also has a tangible impact on how the Court conducts that analysis. The how question has engendered much debate within the Court. While those debates partly continued in Hall, the majority’s opinion confirms that the Court’s approach is more nuanced than a simple tally of legislative decisions for and against a particular punishment or practice.

A. Background on Ongoing Debates Around Consensus Analysis

In The Way the Court Gauges Consensus (and How To Do It Better),⁵⁷ my co-authors and I explain how the Court conducts its consensus analysis and identify some of the debates surrounding that ever evolving approach. We explain that the Court “considers a number of factors . . . : the number of states that authorize the punishment; legislative direction of change; the number of sentences imposed; in the death penalty context, the number of executions carried out; and the degree of geographic isolation.”⁵⁸ While the justices who have dissented from the rulings in Atkins, Simmons, Kennedy, and Graham have taken issue with various particular aspects of the majorities’ analyses, the fundamental debate centers on whether the Court should rely more on states’ statutes or their actual sentencing practices when deciding if a national consensus exists. We describe how the Court’s analysis has become more sophisticated, posit that “punishment usage is a more important indicator of societal mores than whether the punishment is legislatively authorized,” and propose that “[t]he Court should count functionally abolitionist states [based on usage] as abolitionist states. To do so . . . we suggest that the Court incorporate usage indicators before it categorizes states into abolitionist and retentionist columns.”⁵⁹ The majority opinion in Hall confirms our observations about the Court’s increased focus on actual usage and largely ratifies the modification to the consensus analysis we proposed.

B. Critical Aspects of the Hall Consensus Determination

There are at least five critical aspects to the Hall opinion’s method of detecting a national consensus.

First, the Court noted that the direction in which legislatures have moved on an issue and the consistency in that direction is a relevant part of the consensus analysis. While this factor appeared prominently in Atkins and arose again in Simmons, it “was deemphasized in subsequent opinions . . . to the point that it disappeared entirely in recent cases like Graham.”⁶⁰ The Court in Hall evaluated the trend, counting five states that had legislatively abolished the death penalty since Atkins, one state whose statute was struck down by its highest court, and five others that had passed laws allowing defendants claiming intellectual disability to present evidence to support their claim even if they scored higher than seventy on an IQ test.⁶¹ Thus, “The trend inquiry is revived in Hall . . . .”⁶²

Second, the Court definitively included states whose high courts have struck down their capital sentencing schemes in its count of jurisdictions that have abolished the death penalty. In Kennedy v. Louisiana, the majority opinion hinted that the Florida law authorizing the challenged punishment did not render Florida a retentionist state because the Florida Supreme Court had struck down that statute as unconstitutional.⁶³ Based on that opinion, we wrote that “binding opinions requiring either legislative or administrative responses to constitutionalize a punishment may remove the state from the pro-punishment side of the ledger.”⁶⁴ In Hall, the Court made explicit what was implicit about how it views these judicial determinations that state legislation is unconstitutional. It counted New York in the same camp as the five states that had legislatively abolished the death penalty since Atkins, stating that “the New York Court of Appeals invalidated New York’s death penalty under the State Constitution in 2004 . . . and legislation has not been passed to reinstate it.”⁶⁵

Third, Hall deepens the Court’s commitment to analyzing usage indicators to determine if a state’s legislative authorization of a punishment is a meaningful reflection of that state’s popular will. Based on some crucial language in Atkins, we observed that “a state’s failure to execute (or perhaps sentence to death) individuals for long periods of time could arguably be construed as evidence that a state is as good as abolitionist for national consensus purposes.”⁶⁶ In Hall, the Court drew on this same language to describe the situation in Kansas:

Thus, even though Kansas (like Florida) had an IQ cutoff, the Court did not treat it the same as a truly retentionist jurisdiction.⁶⁸ In the Hall context, the Court did not go so far as to consider Kansas an abolitionist state, but it did view the extremely infrequent usage of its death penalty as a legitimate basis for diminishing the import and weight of Kansas’s punishment authorizing legislation.⁶⁹

Fourth, the Court counted Oregon as the equivalent of an abolitionist state because it “has suspended the death penalty and executed only two individuals in the past 40 years.”⁷⁰ One commentator observed that “[i]t is not entirely clear whether [Justice] Kennedy’s characterization of Oregon is influenced more by the fact that Oregon has a gubernatorial moratorium in place, or because it has executed so few people over the past four decades, or some combination of the two. Nevertheless, Kennedy’s doctrinal move is terribly important . . . .”⁷¹ In The Way the Court Gauges Consensus (and How To Do It Better), we do not consider the effect that gubernatorial moratoria may have on the Court’s consensus analysis, and in this way, Hall may go even further in assessing evolving standards of decency than we predicted or proposed.

Fifth, the way the Court characterized Oregon also reveals the most interesting consensus development: Usage indicators can prompt the Court to move a jurisdiction from the retentionist camp to the abolitionist camp. Indeed, for the first time, the Court actually identified “the ledger” when it contrasted the few states with IQ cutoffs to “the 18 States that have abolished the death penalty, either in full or for new offenses, and Oregon . . . .”⁷² The Court’s willingness to engage in a careful analysis and move beyond a black-and-white legislation based headcounting regime stands out. The approach taken in Hall appears to work roughly along the lines of what my coauthors and I proposed: “[R]ather than simply tallying states that do—or do not—legislatively authorize the challenged punishment, the Court should integrate the usage indicators before sorting states into abolitionist or retentionist columns. In other words, the Court should create two categories: ‘functionally abolitionist’ and ‘retentionist.’”⁷³

Conclusion

Despite the prevailing view that the case simply represents an “incremental limitation of the death penalty,”⁷⁴ the Hall opinion may prove to be one of the most compelling and influential decisions of the term. Beyond its immediate holding, the Court’s (apparently noncontroversial) decision to utilize the consensus framework has major implications for individuals challenging not only harsh punishments but also state practices governing how those punishments are handed down. Additionally, the way in which the Court detected the national consensus in Hall definitively answers several key questions that have surrounded its approach. Those responses leave no doubt that the consensus jurisprudence turns in large part on actual sentencing practices and incorporates data about usage into its ledger style analysis. This nuanced approach to detecting consensus ensures that the Court will consider “evidence of declining use” and effectively strike down punishments that have “become obsolete.”⁷⁵
