Prisoners will file a petition for secondary review with the State Supreme Court and, in some cases, with the United States Supreme Court. The cost of defense is also higher; most states required that two defense attorneys be appointed to represent the defendant, and these charges are covered by the state. Additionally, prosecutors are also covered by the state. Additionally, the defense and state normally collect information through private investigators (Mandery 2010)(p.86). Additionally, the defendant has "the right to present unlimited mitigating evidence, guaranteed by Lockett v. Ohio (Mandery, 2010)(p.85). Additionally, the defendant has the right to request a review of his or her case and clemency from the governor. All of these costs must be calculated into the final cost of a death penalty case. It is important to consider that death is different; the state takes a life, it is imperative that the state goes through all the lengthy and costly procedures to ensure that all rights of the accused have been respected.
