The bill proposes to repeal existing sections 565.030 and 565.032 of Missouri law and replace them with new provisions regarding trial procedures for first-degree murder cases. Key changes include the establishment of a two-stage trial process when the death penalty is not waived. In the first stage, the jury will determine the defendant's guilt without considering punishment. If the defendant is found guilty of first-degree murder, the second stage will focus solely on the punishment, which must be assessed and declared by a jury. If a jury trial is waived or not empaneled, the court will impose a sentence of life imprisonment without eligibility for parole, probation, or release except by the governor's action. Additionally, the bill outlines the conditions under which a jury may assess punishment, including the consideration of aggravating and mitigating circumstances. It specifies that if a jury cannot reach a unanimous decision on punishment, the court will impose a life sentence. Furthermore, any defendant sentenced prior to August 28, 2026, under similar circumstances will be eligible for resentencing to life imprisonment without eligibility for parole, probation, or release. The bill also clarifies the definitions of "intellectual disability" and the procedures for addressing this issue prior to trial, ensuring that defendants' rights are preserved throughout the legal process.
