Summary

Background

Michael Lee Marsh II broke into a home, attacked the occupant and set the house on fire; the victim’s 19‑month‑old child was killed. A Kansas jury convicted Marsh of capital murder, found three aggravating circumstances, and unanimously concluded those aggravators were not outweighed by any mitigating circumstances, sentencing him to death. Marsh challenged a Kansas law that says the defendant “shall be sentenced to death” when aggravators are not outweighed; the Kansas Supreme Court struck that law down, and the U.S. Supreme Court agreed to review the question.

Reasoning

The central question was whether the Kansas rule violates the Constitution by directing death when aggravating and mitigating evidence are in equipoise. Relying on Walton v. Arizona and related precedents, the majority held the statute constitutional: a State may require death when the State has proved aggravators beyond a reasonable doubt and the jury finds that mitigating circumstances do not outweigh them, including when the balance is even. The Court stressed that jurors must be allowed to consider any mitigating evidence, that life is the default unless the State meets its burdens, and that Kansas jury instructions properly channel, rather than prevent, individualized sentencing.

Real world impact

Practically, the decision allows prosecutors in Kansas to pursue the death penalty even if a jury considers aggravating and mitigating evidence to be evenly balanced. Capital defendants must therefore press mitigation at sentencing. The ruling reversed the Kansas Supreme Court and remanded the case; Marsh still faces retrial on some charges, so the ruling’s effects will play out in later proceedings.

Dissents or concurrances

Justices Souter and Stevens dissented, warning that DNA‑based exonerations and wrongful‑conviction evidence show real risks and that a tie‑for‑death rule undermines reasoned individualized sentencing; Justice Scalia filed a separate concurrence agreeing with the judgment.
