Brief Fact Summary. An individual convicted of child molestation challenged his conviction based on the state’s failure to preserve certain evidence.
Synopsis of Rule of Law. “[U]nless a criminal defendant can show bad faith on the part of the police, failure to preserve potentially useful evidence does not constitute a denial of due process of law.”
Issue. Does the United States Constitution (the “Constitution”) require the state to preserve evidentiary material that may be useful to a criminal defendant?
Held. No. The majority first observed that this case required them to address “what might loosely be called the area of constitutionally guaranteed access to evidence.” Pursuant to [Brady v. Maryland] the court observed that in the past it held “the suppression by the prosecution of evidence favorable to the accused upon request violates due process where the evidence is material either to guilt or to punishment, irrespective of the good faith or bad faith of the prosecution.” Further, based on [United States v. Agurs] the court observed that it has been held “the prosecution had a duty to disclose some evidence of this description even though no requests were made for it, but at the same time we rejected the notion that a ‘prosecutor has a constitutional duty routinely to deliver his entire file to defense counsel.’ ”
Based on the facts of this case, the majority held that the police did not violate Brady or Agurs. “The State disclosed relevant police reports to respondent, which contained information about the existence of the swab and the clothing, and the boy’s examination at the hospital. The State provided respondent’s expert with the laboratory reports and notes prepared by the police criminologist, and respondent’s expert had access to the swab and to the clothing.”
“[U]nless a criminal defendant can show bad faith on the part of the police, failure to preserve potentially useful evidence does not constitute a denial of due process of law.” “In this case, the police collected the rectal swab and clothing on the night of the crime; respondent was not taken into custody until six weeks later. The failure of the police to refrigerate the clothing and to perform tests on the semen samples can at worst be described as negligent.”
Discussion. The court would have disagreed with the Arizona Court of Appeals if they had held “that the Due Process Clause is violated when the police fail to use a particular investigatory tool.”
