"Failure to Present Evidence of Mental Impairment at Sentencing Constitutes Ineffective Assistance of Counsel"

"The Supreme Court of Louisiana set aside a death sentence in Louisiana v. Hamilton, because trial counsel failed to investigate and present mitigating evidence of the defendant's mental disease at the penalty phase of the trial." [Appelbaum K, J Am Acad Psychiatry Law, Vol 26, No 3, 1998: p. 505-506.]
