341 S.W.3d 221
Tenn.2011Background
- Coleman (death-row inmate) challenged his sentence on grounds of intellectual disability and ineffective assistance of counsel; motion to reopen post-conviction filed in Shelby County; expert Baumeister and Woods testified Coleman’s functional IQ was 70 or below, reflecting intellectual disability; State offered no counter-evidence; trial court denied reopening; Court of Criminal Appeals affirmed; Tennessee Supreme Court granted review.
- Court’s issue centered on whether Tennessee’s intellectual disability statute (Tenn. Code Ann. § 39-13-203) permits non-score evidence to show functional IQ and deficits in adaptive behavior; Atkins v. Virginia and other authorities provided guiding principles; Howell v. State addressed procedural aspects of post-conviction relief and access to investigative resources.
- The Court held that § 39-13-203(a)(1) does not limit to raw IQ scores and allows competent expert testimony on functional IQ; trial-court and appellate determinations based on adaptive-behavior deficits must consider intertwined effects of mental illness and intellectual disability; Court remanded for further proceedings on intellectual disability, and upheld procedural bars on the ineffective-assistance claim absent the proper exceptions.
- The Court clarified that expert testimony must be specific about the IQ as 70 or below, not ranges, and that adaptive-behavior deficits may be demonstrated by clinical evidence consistent with DSM/AAIDD standards; it rejected as procedurally barred Coleman’s ineffective-assistance-of-counsel claim unless exceptions to the post-conviction statute apply.
- The decision also sets forth six guiding principles for applying § 39-13-203 and emphasizes continued use of clinical judgment in borderline cases.
- The opinion uses extensive legislative history and alignments with DSM-IV/AAIDD definitions to interpret the statute and to reject a rigid raw-score-only approach.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether § 39-13-203(a)(1) permits evidence beyond raw IQ scores | Coleman argues raw scores alone determine IA. | State contends raw scores suffice or are determinative. | Statute permits non-score evidence; expert opinions on functional IQ allowed. |
| Whether deficits in adaptive behavior must be proven and how causation is treated | Coleman contends adaptive deficits exist with his intellectual disability. | State argues adaptive deficits must be shown independently of IQ etiology. | Adaptive deficits must be shown; causation between disability and adaptive deficits analyzed; error if misattributed to mental illness. |
| Whether Howell v. State governs the appeal on ineffective assistance claims | Coleman relies on Howell to obtain merits review. | State argues Howell does not create new rights to merits review. | Howell does not authorize merits review; ineffective-assistance claims procedurally barred absent exceptions. |
| Whether Coleman’s ineffective-assistance claim is procedurally barred | Coleman seeks relief despite procedural bars. | State asserts bars apply; earlier determinations stand. | Ineffective-assistance claim barred under post-conviction procedures absent exceptions; remanded only for disability issue. |
