How Atkins v. Virginia applies in Illinois: state-specific rules, key cases, and bar exam notes for Constitutional Law (Eighth Amendment; Criminal Procedure/Death Penalty).
Illinois courts apply the principles established in Atkins v. Virginia by prohibiting the execution of individuals who meet the criteria for intellectual disability. The state has delineated procedures and standards for assessing claims of intellectual disability in capital cases.
In Illinois, a defendant claiming intellectual disability must demonstrate significantly subaverage general intellectual functioning, alongside deficits in adaptive functioning, prior to sentencing to death.
The court ruled that the intellectual disability determination must be made pre-trial, emphasizing the necessity of following the protocols established in Atkins.
This case established that the burden of proof lies with the defendant to establish intellectual disability by clear and convincing evidence to avoid the death penalty.
In this case, the court reiterated that the standards for determining intellectual disability must align with the criteria set out in Atkins, ensuring due process.
Illinois's approach mirrors the federal standard established in Atkins by recognizing intellectual disability as a protective classification against the death penalty. However, Illinois has implemented additional procedural requirements specific to state law that may be more stringent than some federal applications.
Illinois bar exam candidates should understand the implications of Atkins v. Virginia in relation to criminal procedure under the Eighth Amendment, specifically concerning the treatment of intellectual disability in capital cases.
