Evidence On Fire, Valena Beety, Jennifer Oliva

Articles by Maurer Faculty

Fire science, a field largely developed by lay “arson investigators,” police officers, or similar first responders untrained in chemistry and physics, has been historically dominated by unreliable methodology, demonstrably false conclusions, and concomitant miscarriages of justice. Fire investigators are neither subject to proficiency testing nor required to obtain more than a high school education. Perhaps surprisingly, courts have largely spared many of the now debunked tenets of fire investigation any serious scientific scrutiny in criminal arson cases. This Article contrasts the courts’ ongoing lax admissibility of unreliable fire-science evidence in criminal cases with their strict exclusion of the same flimsy …

Debunked, Discredited, But Still Defended: Why Prosecutors Resist Challenges To Bad Science And Some Suggestions For Crafting Remedies For Wrongful Conviction Based On Changed Science, Aviva A. Orenstein

Articles by Maurer Faculty

Flawed science has significantly contributed to wrongful convictions. Courts struggle with how to address such convictions when the mistaken science (such as bogus expert claims about the differences between accidental fires and intentionally set ones) significantly affected the guilty verdict but there is no DNA evidence to directly exonerate the accused. My short piece explores why prosecutors often defend bad science. Mistakes in science tend to serve the prosecution, but there are other more subtle factors that explain prosecutors’ reluctance to address flawed forensic testimony. Such reluctance may arise from fondness for the status quo and a resistance to subverting …

Discovering Forensic Fraud, Jennifer Oliva, Valena Beety

Articles by Maurer Faculty

This Essay posits that certain structural dynamics, which dominate criminal proceedings, significantly contribute to the admissibility of faulty forensic science in criminal trials. The authors believe that these dynamics are more insidious than questionable individual prosecutorial or judicial behavior in this context. Not only are judges likely to be former prosecutors, prosecutors are “repeat players” in criminal litigation and, as such, routinely support reduced pretrial protections for defendants. Therefore, we argue that the significant discrepancies between the civil and criminal pretrial discovery and disclosure rules warrant additional scrutiny.

In the criminal system, the near absence of any pretrial discovery means …

Changing The Culture Of Disclosure And Forensics, Valena Beety

Articles by Maurer Faculty

This Essay responds to Professor Brandon Garrett’s Constitutional Regulation of Forensic Evidence, and, in particular, his identification of the dire need to change the culture of disclosing forensic evidence. My work on forensics is—similarly to Garrett’s—rooted in both scholarship and litigation of wrongful convictions. From this perspective, I question whether prosecutors fully disclose forensics findings and whether defense attorneys understand these findings and their impact on a client’s case. To clarify forensic findings for the entire courtroom, this Essay suggests increased pre-trial discovery and disclosure of forensic evidence and forensic experts. Forensic analysts largely work in police-governed labs; therefore, this …

Special Issues Raised By Rape Trials, Aviva A. Orenstein

Articles by Maurer Faculty

Rape cases reveal core conflicts in the space where evidence, law, and ethics intersect. Such conflicts include the tension between victim protection and the rights of the accused, the challenges attorneys face trying to negotiate the demands of sensitive and emotionally difficult cases, and the role of the law in counteracting stereotypes and bias.

In this essay, I will begin by presenting the cultural milieu surrounding rape allegations, briefly reviewing attitudes towards perpetrators and victims. Next, I will attempt to capture the legal zeitgeist concerning rape, focusing on two recent phenomena: the reversal of false rape convictions based on DNA …

Deviance, Due Process, And The False Promise Of Federal Rule Of Evidence 403, Aviva A. Orenstein

Articles by Maurer Faculty

In a significant break with traditional evidence rules and policies, Federal Rules of Evidence 413 and 414 (concerning rape and child abuse, respectively) allow jurors to use the accused's prior sexual misconduct as evidence of character and propensity. Courts have rejected due process challenges to the new rules, holding that Federal Rule of Evidence 403 serves as a check on any fairness concerns. However, courts' application of Rule 403 in cases involving these sexual propensity rules is troubling. Relying on the legislative history of the new rules and announcing a presumption of admissibility, courts have forsaken the traditional operation of …

Evidence: Survey Of Recent Developments In Indiana Law, J. Alexander Tanford

Articles by Maurer Faculty

With rare exceptions, Indiana evidence law progresses slowly and holds closely to the traditional concepts of the common law. This Survey Article collects the several important cases decided during the past year that continue this development of Indiana's common law of evidence. A general word of caution is in order concerning the Indiana appellate courts' evidence cases. Most evidence issues arise in criminal cases, in which convicted defendants allege error in the admission of evidence against them or in the exclusion of evidence offered in their defense. A ruling in favor of the defendant could result in the reversal of …
