McCleskey v. Kemp

1987-06-08

Headline: Court upholds Georgia death sentence and rejects challenge based only on a statewide statistical study of racial disparities, limiting the use of broad statistics to overturn individual capital sentences.

Holding: The Court held that a statewide statistical study showing racial disparities in Georgia death sentences did not prove Warren McCleskey’s individual death sentence unconstitutional, and it affirmed the lower courts’ denials of relief.

Real World Impact:

Prevents overturning individual death sentences based solely on statewide statistical disparities.
Affirms prosecutorial and jury discretion absent case-specific proof of racial intent.
Pushes policy responses to legislatures rather than courts for broad racial disparities.

Topics: death penalty, race and sentencing, statistical evidence, prosecutorial discretion

Summary

Background

Warren McCleskey, a Black man, was convicted in Georgia for killing a white police officer during a 1978 furniture-store robbery. A jury recommended the death penalty and the state court imposed it. McCleskey presented the Baldus study, a statistical analysis of over 2,000 Georgia murder cases showing much higher death‑sentence rates when the victim was white (raw rates such as 11% versus 1%), and a model finding defendants who killed white victims were about 4.3 times more likely to receive death.

Reasoning

The main question was whether those statistics alone made McCleskey’s death sentence unconstitutional under the ban on cruel or unusual punishment and the guarantee of equal treatment. The Court assumed the study’s validity but said a defendant must show purposeful discrimination in his specific case. It stressed that prosecutors and juries have lawful discretion, described Georgia’s procedural safeguards (narrow aggravating factors, separate penalty hearings, and automatic review), and concluded that statewide disparities by themselves did not prove unconstitutional bias in McCleskey’s sentencing.

Real world impact

The decision makes it harder for an individual on death row to overturn a sentence solely by pointing to statewide statistical disparities. It preserves prosecutors’ and juries’ discretion unless case-specific proof of racial intent appears. The Court pointed to legislatures as the better forum to address broad statistical disparities, so policy or statutory reform — not immediate court-ordered relief — is the likely avenue for systemic change. The judgment affirmed McCleskey’s death sentence.

Dissents or concurrances

Several Justices dissented, arguing the Baldus study showed a high likelihood race influenced who received the death penalty and that such a risk is intolerable for capital punishment; they urged further review or remedial narrowing of death-eligible cases.
