SCOTUS Grapples With COMPLEX Case – Death Penalty or Disability Issue?

The Supreme Court building featuring marble columns and a clear blue sky

The real fight in Hamm v. Smith is not about one Alabama inmate, but about whether the government can redefine “intellectual disability” so narrowly that the Constitution’s promise becomes a technicality.

Story Snapshot

The Supreme Court will decide whether IQ scores alone can determine who is too disabled to execute.
Alabama is pushing a number-driven test; clinicians and disability advocates insist on holistic evaluation.
The ruling will shape who lives or dies on death row and could influence disability law far beyond capital cases.
The case will reveal whether this Court still treats science and precedent as guardrails on state power.

Why This Case Turns “Intellectual Disability” Into a Constitutional Fault Line

The question in Hamm v. Smith sounds clinical, but it cuts straight to constitutional muscle: who counts as so intellectually disabled that the state may not kill him. Joseph Clifton Smith, sentenced to die for a 1997 Alabama murder, argues he meets long‑standing clinical criteria for intellectual disability and is therefore categorically ineligible for execution under Atkins v. Virginia. Alabama responds with a blunt tool, IQ numbers as gatekeeper, with everything else pushed to the margins.

That numerical obsession is not a glitch; it is the feature Alabama wants the Court to endorse nationwide. Disability organizations warn that if the justices bless an IQ‑centric rule, states will have a ready script for shaving down who qualifies as disabled enough to be spared death. The fight is not about whether people with intellectual disability may be executed, Atkins already said no—but about who controls the definition: clinicians guided by science, or governments guided by their own sentencing priorities.

How We Got From Atkins to Alabama’s IQ-Only Play

More than two decades ago, Atkins held that executing people with intellectual disability violates the Eighth Amendment’s ban on cruel and unusual punishments. The Court recognized that such individuals have diminished reasoning and impulse control, lowering their moral culpability and increasing the risk of wrongful execution. But Atkins left states room to define the term, and many used that space aggressively, turning IQ scores into bright lines and importing stereotypes into the diagnosis process.

The Court pushed back in Hall v. Florida, striking down Florida’s rigid rule that treated an IQ score of 70 as an absolute cutoff and ignored the standard error of measurement and other evidence. Then in Moore v. Texas, it rejected Texas’s home‑grown “Briseno factors,” insisting that courts must look to current medical standards instead of lay impressions and outdated notions of disability. Together, those cases built a simple principle: the Constitution’s protection is real only if states use medically grounded, holistic criteria rather than cherry‑picked numbers or caricatures.

What Makes Hamm v. Smith Different—and More Dangerous

Hamm v. Smith is not merely another state caught ignoring Moore’s instructions. Alabama asks the Court to effectively re‑write the ground rules by letting IQ scores carry decisive weight and shrinking the role of adaptive‑behavior evidence. Disability advocates argue this move would “upend decades of precedent, ignore science, and put people with intellectual disability at risk of unlawful execution.” Their concern aligns with basic common sense: a single test score, taken years ago under unknown conditions, should not be trusted with life‑or‑death power.

Clinicians define intellectual disability with three components: significantly subaverage intellectual functioning, deficits in adaptive functioning, and onset during the developmental period. Professional bodies like AAIDD and the APA stress that diagnosis demands comprehensive evaluation, not a lone number ripped from its context. A Court that previously required states to track “current medical standards” would have to contort its own words to let Alabama downgrade those standards into a spreadsheet exercise.

Beyond One Man’s Sentence: What This Means for Death Row and Everyday Disability Law

The immediate human stakes are brutal and simple. If the Court reaffirms a holistic, science‑based standard, Smith and many others with similar profiles have a genuine chance to prove intellectual disability and escape execution. If the justices side with Alabama’s number‑first vision, those same individuals may be put to death because a test once reported 72 instead of 69. For a Court that often invokes originalism and textualism, the basic conservative instinct to avoid irreversible error in government power should weigh heavily here.

The longer‑term effects will not stay confined to death row. Legal analysts warn that whatever standard the Court endorses could spill into how agencies and courts define intellectual disability in areas like Social Security disability benefits and educational services. A narrow, IQ‑driven constitutional definition would hand cost‑conscious bureaucracies and school systems a ready-made excuse to tighten eligibility. A decision that embraces AAIDD and DSM criteria would instead reinforce clinically grounded protections across the legal landscape.

What This Case Reveals About the Court’s View of Science, States, and Human Limits

The amicus brief filed by The Arc, AAIDD, the Bazelon Center, and the National Disability Rights Network frames this as a test of whether settled law still means what it says. They remind the Court that “it is settled law that executing people with intellectual disability is unconstitutional,” and accuse Alabama of asking the justices “to erase that precedent and focus exclusively on IQ scores.” Their warning carries special weight because these same groups helped build the Atkins, Hall, and Moore framework in the first place.

From a conservative, limited‑government perspective, the core issue is whether states can narrow fundamental rights by manipulating definitions. If the state may redefine disability downward whenever constitutional protections become inconvenient, then no categorical safeguard is truly safe. The justices will not just be deciding one man’s fate; they will be signaling whether constitutional limits on punishment track enduring standards of decency and sound science, or yield whenever a state finds them burdensome.
