170 F. Supp. 3d 347
E.D.N.Y2016Background
- Defendant Ronell Wilson was convicted in 2006 of murdering two undercover NYPD detectives and twice sentenced to death; the Second Circuit vacated the first death sentence and remanded for penalty retrial; after a second jury again imposed death, the court initially found Wilson not intellectually disabled.
- Following the Supreme Court’s decision in Hall v. Florida, the Second Circuit sua sponte remanded for reconsideration of Wilson’s Atkins claim in light of Hall. The court therefore reopened analysis focused on how Hall affects IQ-score treatment and whether adaptive-functioning evidence must be considered.
- The court adopted the three-prong legal test for intellectual disability (1) significantly subaverage intellectual functioning; (2) significant adaptive deficits; (3) onset before age 18 — following AAIDD/APA guidance but retaining a legal (not purely clinical) standard.
- Applying Hall, the court construed Hall to require treating each IQ score as a range using the test-specific SEM and (as the court determined) a 95% confidence interval (± two SEMs); under that framework at least one pre-18 IQ test for Wilson produced a range reaching 70 or below.
- The parties’ experts (defense and government) agreed Wilson had adaptive deficits, though the Government attributed them to learning/behavioral disorders rather than intellectual disability; the court found the record showed pervasive childhood deficits in conceptual and social domains that arose before age 18 and were directly related to intellectual impairments.
Issues
| Issue | Plaintiff's Argument (Wilson) | Defendant's Argument (Government) | Held |
|---|---|---|---|
| Effect of DSM‑V on legal test | DSM‑V creates a holistic test; IQ should not predominate; DSM‑V requires re-opening hearing | DSM‑V does not materially change the three‑prong framework; no new hearing needed | DSM‑V does not change the independent three‑prong legal structure; no new evidentiary hearing required; apply DSM‑V/AAIDD terminology to existing record |
| How to apply SEM/confidence interval post‑Hall | Use SEM and consider adaptive evidence when appropriate; focus on ranges | Opposed to expanding prong one via broad intervals; favors narrower approach | Hall requires using SEM; court interprets Hall to justify applying test‑specific SEM with a 95% confidence interval (± two SEMs) for Atkins analysis |
| Multiple/inconsistent IQ scores | Holistic consideration; allow adaptive evidence if any valid test’s range reaches ≤70 | Multiple consistent >70 scores defeat claim; causation/alternative diagnoses matter | If any valid pre‑18 IQ test, evaluated with 95% CI, yields a range reaching ≤70, court must consider adaptive functioning; multiple scores do not negate that requirement |
| Prong II causation requirement | Adaptive deficits need not be proven to be caused exclusively by intellectual disability; may co‑occur with other disorders | Adaptive deficits must be shown to be caused by intellectual disability (not just by ADHD, learning disorders, conduct) | Court rejects requirement to rule out other causes; plaintiff need only show adaptive deficits directly related to intellectual impairments (no exclusive‑cause rule) |
