Junk Science At Sentencing, Maneka Sinha

Faculty Scholarship

Junk science used in criminal trials has contributed to hundreds of wrongful convictions. But the problem is much worse than that. Junk science does not only harm criminal defendants who go to trial, but also the overwhelming majority of defendants—over ninety-five percent—who plead guilty, skip trial, and proceed straight to sentencing.

Scientific, technical, and other specialized evidence (“STS evidence”) is used regularly, and with increasing frequency, at sentencing. Despite this, Federal Rule of Evidence 702 and its state equivalents—which help filter unreliable STS evidence at trials—do not apply at the critical sentencing stage. In fact, at sentencing, no meaningful admissibility …

Changed Science Writs And State Habeas Relief, Valena Beety

Articles by Maurer Faculty

For decades now, the 1996 federal Antiterrorism and Effective Death Penalty Act (AEDPA) has limited the scope and influence of federal courts in post-conviction case review, forcing convicted individuals to rely instead on state habeas proceedings for conviction relief. Due in large part to the 2009 National Academy of Sciences Report, petitions for conviction relief increasingly include challenges to the government’s scientific evidence at trial. These petitions analyze that evidence by comparing the trial evidence to the advancement of scientific findings and scientific knowledge in the years since the trial. State habeas petitions thus provide an avenue for relief from …

Does the Confrontation Clause permit the prosecution to introduce a forensic laboratory report through the in-court testimony of a supervisor or other person who did not perform or observe the reported test?

Statistics In The Jury Box: How Jurors Respond To Mitochondrial Dna Match Probabilities, David H. Kaye, Valerie P. Hans, B. Michael Dann, Erin J. Farley, Stephanie Albertson

Cornell Law Faculty Publications

This article describes parts of an unusually realistic experiment on the comprehension of expert testimony on mitochondrial DNA (mtDNA) sequencing in a criminal trial for robbery. Specifically, we examine how jurors who responded to summonses for jury duty evaluated portions of videotaped testimony involving probabilities and statistics. Although some jurors showed susceptibility to classic fallacies in interpreting conditional probabilities, the jurors as a whole were not overwhelmed by a 99.98% exclusion probability that the prosecution presented. Cognitive errors favoring the defense were more prevalent than ones favoring the prosecution. These findings lend scant support to the legal argument that mtDNA …

Misuse Of Scientific Evidence By Prosecutors, Bennett L. Gershman

Elisabeth Haub School of Law Faculty Publications

The prosecutor's misuse of scientific evidence to charge and convict has not been sufficiently examined. Courts and commentators critiquing abuses of scientific evidence in criminal cases rarely focus on the prosecutor's role in the process. Issues typically discussed are the questionable nature of the evidence, the controversial manner in which the evidence was acquired and tested, whether the expert arrived at her conclusions in a scientifically reliable manner, and whether the expert's courtroom testimony was false or misleading. The prosecutor's control over and manipulation of the scientific evidence to shape the fact-finder's evaluation of the facts and to persuade the …

The Jury And Scientific Evidence, Richard O. Lempert

Articles

Read court decisions and commentaries from 100, or evenfive years ago, and you will find that experts and scientific evidence were causing problems then just as they are causing problems now. I do not think that Daubert, Kumho Tire, or any change in a rule of evidence will keep expert scientific testimony from being a difficult area for the legal system. Yet we must still ask: "What are the best terms on which to deal with scientific experts, and how can weimprove the system?"
