The Incongruence Principle Of Evidence, Hillel Bavli

Faculty Journal Articles and Book Chapters

Evidence law assumes that the meaning and value of information at trial is equal to the meaning and value of the same information in the real world. This premise underlies evidence policy, judicial applications of evidence law, and instructions to jurors for evaluating evidence. However, it is incorrect, and the law’s failure to recognize this hinders its aims of accuracy and equality.

In this article, I draw on fields outside of law - including Bayesian inference and cognitive psychology - to develop a model of evidence that describes how jurors combine new evidence with prior beliefs (or “priors”) to make …

Criminal Justice Secrets, Meghan J. Ryan

Faculty Journal Articles and Book Chapters

The American criminal justice system is cloaked in secrecy. The government employs covert surveillance operations. Grand-jury proceedings are hidden from public view. Prosecutors engage in closed-door plea-bargaining and bury exculpatory evidence. Juries convict defendants on secret evidence. Jury deliberations are a black box. And jails and prisons implement clandestine punishment practices. Although there are some justifications for this secrecy, the ubiquitous nature of it is contrary to this nation’s Founders’ steadfast belief in the transparency of criminal justice proceedings. Further, the pervasiveness of secrecy within today’s criminal justice system raises serious constitutional concerns. The accumulation of secrecy and the aggregation …

Evidence Laundering In A Post-Herring World, Kay L. Levine, Jenia I. Turner, Ronald F. Wright

Faculty Journal Articles and Book Chapters

The Supreme Court’s decision in Herring v. United States authorizes police to defeat the Fourth Amendment’s protections through a process we call evidence laundering. Evidence laundering occurs when one police officer makes a constitutional mistake when gathering evidence and then passes that evidence along to a second officer, who develops it further and then delivers it to prosecutors for use in a criminal case. When courts admit the evidence based on the good faith of the second officer, the original constitutional taint disappears in the wash.

In the years since Herring was decided, courts have allowed evidence laundering in a …

No-Limit Texas Hold 'Em, Or, The Voir Dire In Dallas County, Jeffrey D. Kahn

Faculty Journal Articles and Book Chapters

Voir dire is Law French for “to speak the truth.” In the United States and a few other common-law countries that still use juries, the term describes the process of selecting jurors who will hear the evidence presented at trial, render a verdict, and sometimes determine punishment. The translation suggests a search for jurors who can render a fair and impartial verdict. Attorneys try to discover and remove jurors who seem unable or unlikely to speak the truth, such as those who nurture irrational prejudices or harbor private grievances.

In most federal courts, the judge is the primary conduit for …
