What it's about

The Supreme Court overturned the appeals court’s ruling, finding Alabama’s decision that Madison was mentally able to be executed was not unreasonable enough for a federal court to grant relief; it did not decide whether a state may execute someone who cannot remember the crime.

At a hearing, both psychologists said Madison understood he faced execution for murder. The psychologist hired by Madison’s lawyer said strokes had left him unable to remember the crime; the court-appointed psychologist found he understood his case and sentence.

An Alabama trial court refused to pause Madison’s death sentence after finding he understood he was to be executed as punishment for murder.

Question presented
