Summary

Background

A North Carolina man, Arthur Boyd, was convicted of murdering his former girlfriend after a failed attempt at reconciliation. They had lived together for three years and separated months earlier; they met at a shopping mall and Boyd stabbed her repeatedly until bystanders separated them. At the sentencing hearing, Boyd offered expert testimony from a sociologist who had studied people who kill intimates. The trial judge excluded the expert’s entire testimony about Boyd’s life history and motives.

Reasoning

The core issue raised in Justice Marshall’s dissent is whether the judge properly prevented the jury from hearing expert evidence that linked Boyd’s traumatic life history to a self-destructive motive. Marshall argues that established Eighth Amendment protections require that a sentencer be allowed to consider any relevant mitigating evidence about a defendant’s life and motives. He contends the exclusion violated prior decisions that let juries weigh the importance of mitigation, and that the state court’s affirmation wrongly treated the expert evidence as merely a criminal “profile” rather than relevant mitigation.

Real world impact

Because the full Court declined to review the case, the state court’s decision affirming the death sentence remains in place. Marshall warns that the decision—when combined with similar state rulings—could permit courts to narrow what counts as admissible mitigation and thus limit the information juries hear about a defendant’s life and motive. The dissent characterizes this trend as an erosion of protections meant to ensure individualized sentencing in capital cases.

Dissents or concurrances

Justice Marshall, joined by Justice Brennan, dissented from the denial of review and would have granted review; he also reiterated his view that the death penalty is constitutionally impermissible in all circumstances.
