A Common Law View Of Causation, Science And Statistical Evidence In The Courtroom, Basil C. Bitas

Research Collection Yong Pung How School Of Law

In March 2010, the Australian High Court in Amaca Ltd v Ellis [2010] HCA 5 (“Amaca”) moved assertively to clarify the approach of the Australian courts to causation in cases of lung disease involving multiple pathogens. The court demonstrated sensitivity to both the scientific and legal inquiries while reaffirming the obligation of plaintiffs to prove causation based on the balance of probabilities. In examining the plaintiff’s statistical evidence, the court established important guideposts regarding the proper use and interpretation of epidemiology in the courtroom, highlighting both the relevance and limits of such proof regarding causation and the satisfaction of the …

She Blinded Me With Science: Wrongful Convictions And The "Reverse Csi-Effect", Mark A. Godsey, Marie Alou

Faculty Articles and Other Publications

Prosecutors in the United States are often heard to complain these days of the "CSI-effect."' When they make this complaint, they mean that the popularity of television shows like CSI has made it unduly difficult for them to obtain convictions of guilty defendants. Jurors today have become spoiled as a result of the proliferation of these "high-tech" forensic shows, and now unrealistically expect conclusive scientific proof of guilt before they will convict. The unfortunate result is that guilty defendants are acquitted because of a lack of forensic evidence in cases where, in reality, no such forensic evidence was possible or …

An Economic Analysis Of Fact Witness Payment, Eugene Kontorovich, Ezra Friedman

Faculty Working Papers

In this paper we discuss the disparate treatment of perceptual (''fact'') witnesses and expert witnesses in the legal system. We highlight the distinction between the perceptual act of witnessing and the act of testifying, and argue that although there might be good reasons to regulate payments to fact witnesses, the customary prohibition on paying them for their services is not justified by reference to economic theory. We propose considering a court mediated system for compensating fact witnesses so as to encourage witnessing of legally important events.We construct a simple model of witness incentives, and simulate the effects of several possible …

Moral Character, Motive, And The Psychology Of Blame, Janice Nadler, Mary-Hunter Morris Mcdonnell

Faculty Working Papers

Blameworthiness, in the criminal law context, is conceived as the carefully calculated end product of discrete judgments about a transgressor's intentionality, causal proximity to harm, and the harm's foreseeability. Research in social psychology, on the other hand, suggests that blaming is often intuitive and automatic, driven by a natural impulsive desire to express and defend social values and expectations. The motivational processes that underlie psychological blame suggest that judgments of legal blame are influenced by factors the law does not always explicitly recognize or encourage. In this Article we focus on two highly related motivational processes – the desire to …

If The Shoe Fits They Might Acquit: The Value Of Forensic Science Testimony, Jonathan Koehler

Faculty Working Papers

The probative value of forensic science evidence (such as a shoeprint) varies widely depending on how the evidence and hypothesis of interest is characterized. This paper uses a likelihood ratio (LR) approach to identify the probative value of forensic science evidence. It argues that the "evidence" component should be characterized as a "reported match," and that the hypothesis component should be characterized as "the matching person or object is the source of the crime scene sample." This characterization of the LR forces examiners to incorporate risks from sample mix-ups and examiner error into their match statistics. But how will legal …

When Machines Are Watching: How Warrantless Use Of Gps Surveillance Technology Violates The Fourth Amendment Right Against Unreasonable Searches, David Thaw, Priscilla Smith, Nabiha Syed, Albert Wong

Articles

Federal and state law enforcement officials throughout the nation are currently using Global Positioning System (GPS) technology for automated, prolonged surveillance without obtaining warrants. As a result, cases are proliferating in which criminal defendants are challenging law enforcement’s warrantless uses of GPS surveillance technology, and courts are looking for direction from the Supreme Court. Most recently, a split has emerged between the Ninth and D.C. Circuit Courts of Appeal on the issue. In United States v. Pineda-Moreno, the Ninth Circuit relied on United States v. Knotts — which approved the limited use of beeper technology without a warrant — to …

Hanging On By A Thread: The Exclusionary Rule (Or What's Left Of It) Lives For Another Day, David A. Moran

Articles

Back when there was a Soviet Union, foreign intelligence officers would anxiously await the May Day parade in Moscow to see who would be standing next to the chairman of the Communist Party and who would be missing from the reviewing platform altogether. Since the Soviet government and the statecontrolled press published very little about what was really going on in the halls of state power, this was considered the most reliable way to determine who was in or out of favor and, by extension, how the domestic and foreign policies of the world's second most powerful country were likely …

Who Must Testify To The Results Of A Forensic Laboratory Test? Bullcoming V. New Mexico, Richard D. Friedman

Articles

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?

"Sweet Childish Days": Using Developmental Psychology Research In Evaluating The Admissibility Of Out-Of-Court Statements By Young Children, Lynn Mclain

All Faculty Scholarship

A three-year-old child, while being bathed by her babysitter, innocently mentions that her “pee-pee” hurts. When the babysitter asks the child how she hurt it, she says, “Uncle Ernie (her mother’s boyfriend) told me not to tell.” A subsequent medical examination reveals that the child has gonorrhea, a sexually transmitted disease.

By the time of trial, the child is four and-a-half-years old. When questioned by the trial judge, she cannot explain to the judge’s satisfaction, “the difference between the truth and a lie.” Moreover, she has no long term memory of the incident. The judge rules the child incompetent to …
