The United States Supreme Court is poised to deliver a significant ruling in the case of Hamm v Smith, an Alabama death penalty appeal that could have far-reaching implications for the execution of individuals with intellectual disabilities. The decision is anticipated to determine whether the criteria for deeming someone eligible for capital punishment, despite intellectual limitations, will be broadened, potentially leading to an increase in such executions.
At the heart of the case is Joseph Smith, a man whose intellectual capacity has been a central point of contention. Smith's five recorded IQ scores—72, 74, 74, 75, and 78—all fall within a range that typically indicates intellectual disability. Despite these scores, the State of Alabama is actively seeking to proceed with his execution. This challenge to established understandings of intellectual disability in capital cases has drawn considerable attention from legal experts and human rights organisations.
The US Supreme Court previously ruled in Atkins v Virginia (2002) that executing individuals with intellectual disabilities constitutes 'cruel and unusual punishment' and is therefore unconstitutional under the Eighth Amendment. Subsequent rulings, such as Hall v Florida (2014) and Moore v Texas (2017), have further clarified and reinforced the standards for determining intellectual disability in capital cases, emphasising a holistic assessment rather than a rigid IQ cutoff.
Should the Supreme Court rule in Alabama's favour in Hamm v Smith, it could effectively weaken these protections, potentially making it easier for states to argue for the execution of individuals who present evidence of intellectual disability. Such a decision would represent a significant shift in judicial interpretation and could be seen as a retreat from the protections established over the past two decades. Critics argue that expanding the scope for such executions would contravene international human rights standards and undermine the principle of justice for vulnerable individuals.
The implications of this ruling extend beyond the immediate case of Joseph Smith. Legal scholars and human rights advocates are closely monitoring the decision, fearing that it could set a precedent that erodes the constitutional safeguards designed to prevent the execution of those least able to comprehend their crimes or participate effectively in their defence. The outcome will be a crucial indicator of the US Supreme Court's current stance on the intersection of intellectual disability and capital punishment.
