In cases involving the death penalty, use of a PTSD diagnosis as a sentencing mitigating factor has been considered in the postconviction appeals process. This article analyzes a decade of American federal appellate case law regarding postconviction claims of ineffective assistance of counsel by capital defendants in regard to investigating and litigating trauma and PTSD. We found a high tolerance by the courts for deficient investigating, ruling against the petitioner in 20 of 23 (87%) of identified cases. The article discusses how these situations might be avoided and explores the critical role of forensic psychiatrists and mitigation specialists in investigating and presenting trauma to the court.
