Three decades ago, the US Supreme Court declared in McCleskey v Kemp that legislatures, rather than courts, should redress statistically identified disparities in death sentencing. Racial justice efforts failed in Congress, but two states adopted measures that challenge inequalities in capital punishment. This article critically examines the development and impacts of the North Carolina and Kentucky Racial Justice Acts. Findings reveal two policy implications. The acts first actualised judicial wishes for elected officials and the public to address sentencing disparities. Secondly, the policies became distinct ‘super due process’ remedies that require defendants to show racial disparity as an error under specific procedures. Variation in the acts’ approaches to proof and causes of discrimination contributed to differential impact: the questioning of all death sentences within four years in North Carolina and minimal relief in Kentucky for two decades. Lessons are drawn for designing disparity reforms in criminal processing following judicial non-intervention.
