The Supreme Court has declined to intervene in a contentious death penalty case involving an Alabama prisoner whose fluctuating intelligence test scores raise questions about his mental fitness for execution.
The inmate, convicted of murder, challenged his capital sentence by citing inconsistent results across multiple IQ evaluations. The varying test outcomes created ambiguity about whether he meets the legal threshold for intellectual disability, a factor that can spare death row inmates from capital punishment under established precedent.
By choosing not to hear the case, the justices avoided a direct ruling that could have clarified how courts should handle conflicting psychological assessments when determining eligibility for execution. The decision leaves the lower court ruling intact and provides no new guidance on this recurring issue in capital cases.
The case touches on a longstanding legal question: when test scores swing considerably, which results should carry the most weight in determining intellectual capacity? Courts have struggled with this tension as defendants have challenged convictions and sentences partly based on IQ fluctuations and questions about testing methodology.
The prisoner's legal team argued that the variation in results cast enough doubt on his intellectual functioning to warrant protection from execution. The state maintained that the convict's sentence should stand based on the available evidence.
Without taking the case, the Supreme Court leaves individual states and lower courts to navigate these disputes on their own, continuing a patchwork approach to intellectual disability claims in death penalty litigation.
Author Sarah Mitchell: "The court's silence on this issue practically guarantees more of these fights will drag through state courts, leaving the same uncertainty unresolved."
