Narrative Opinion Summary
The case involves a defendant charged with capital murder in Texas, who was found competent to stand trial despite being diagnosed with mild to moderate mental retardation. The defendant's insanity defense, based on evidence of organic brain damage and childhood abuse, was rejected by the jury, leading to a conviction. During the penalty phase, the jury considered special issues without adequate instructions on mitigating evidence, resulting in a death sentence. The Texas Court of Criminal Appeals upheld the sentence, dismissing claims of Eighth Amendment violations. However, the Supreme Court partially reversed and remanded the case, emphasizing that Texas juries must be instructed to consider mitigating evidence related to mental retardation and childhood abuse. The Court ruled that this requirement does not constitute a 'new rule' under Teague v. Lane, allowing its application in this case. The decision highlights the necessity for individualized assessments in capital sentencing, particularly for mentally retarded individuals, in line with precedents set by Lockett v. Ohio and Eddings v. Oklahoma. The Court acknowledged the importance of ensuring that mitigating evidence is considered in determining the appropriateness of the death penalty, even without a national consensus against executing mentally retarded individuals.
