Johnson v. Mississippi

Background

A man convicted of murder in Mississippi was sentenced to death after a jury found three aggravating factors, one of which relied on a 1963 New York felony conviction. Years later the New York Court of Appeals reversed that 1963 conviction, and the defendant asked the Mississippi courts to reconsider his death sentence because it had depended in part on that now-invalid conviction. The Mississippi Supreme Court denied relief, and the case reached this Court.

Reasoning

The Court addressed whether a death sentence may stand when it was in part based on a prior conviction that has been reversed. Emphasizing the special need for reliability in capital cases, the Court explained that the only proof of the alleged prior offense was a document showing the old conviction. Because that conviction has been invalidated, it no longer legitimately supported the death sentence and its introduction was prejudicial. The Court therefore reversed the judgment and sent the case back to the Mississippi Supreme Court for further proceedings that do not rely on the invalid conviction.

Real world impact

The ruling means states may not rely on a later-vacated prior conviction as an aggravating factor without reexamining the sentencing decision. Defendants whose death sentences rest partly on overturned convictions may obtain reconsideration. The decision does not permanently decide the final sentence; the state courts must now determine how to proceed in a way consistent with this opinion.

Dissents or concurrances

Two concurring opinions add perspective: one Justice would bar the death penalty entirely and would prevent reimposition of death; another concurred but left the state court the option to hold a new sentencing hearing or to reweigh the remaining factors.
