Admissibility Of Scientific Evidence Under Daubert: The Fatal Flaws Of ‘Falsifiability’ And ‘Falsification’, Barbara P. Billauer Esq

barbara p billauer esq

Abstract: The Daubert mantra demands that judges, acting as gatekeepers, prevent para, pseudo or ‘bad’ science from infiltrating the courtroom. To do so, the Judges must first determine what “science” is? And then, what ‘good science’ is? It is submitted that Daubert is seriously polluted with the notions of Karl Popper who sets ‘falsifiability’ and ‘falsification’ as the demarcation line for that determination. This inapt philosophy has intractably infected case law, leading to bad decisions immortalized as stare decisis. Among other problems, is the intolerance of Popper’s system for multiple causation, a key component of toxic- torts. Thus, the primary …

Daubert Debunked: A History Of Legal Retrogression A History Of Legal Retrogression And The Need To Reassess ‘Scientific Admissibility’, Barbara P. Billauer Esq

barbara p billauer esq

Abstract: With ‘novel’ scientific discoveries accelerating at an unrelenting pace, the need for accessible and implementable standards for evaluating the legal admissibility of scientific evidence becomes more and more crucial. As science changes, legal standards for evaluating ‘novel’ science must be plastic enough to respond to fast-moving changes. This, ostensibly, was the Daubert objective. Since it was decided in 1993, however, Daubert’s impact has been hotly contested -- with plaintiffs and defendants each claiming the decision unfairly favors the other side. New approaches are constantly suggested to deal with the perceived impact, although there is no uniform consensus of exactly …

Implementing The Lessons From Wrongful Convictions: An Empirical Analysis Of Eyewitness Identification Reform Strategies, Keith A. Findley

Keith A Findley

Learning about the flaws in the criminal justice system that have produced wrongful convictions has progressed at a dramatic pace since the first innocent individuals were exonerated by postconviction DNA testing in 1989. Application of that knowledge to improving the criminal justice system, however, has lagged far behind the growth in knowledge. Likewise, while considerable scholarship has been devoted to identifying the factors that produce wrongful convictions, very little scholarly attention has been devoted to the processes through which knowledge about causes is translated into reforms.

Using eyewitness misidentification—one of the leading contributors to wrongful convictions and the most thoroughly …

Visualizing Dna Proof, Nicholas L. Georgakopoulos

Nicholas L Georgakopoulos

DNA proof inherently involves the use of probability theory, which is often counterintuitive. Visual depictions of probability theory, however, can clarify the analysis and make it tractable. A DNA hit from a large database is a notoriously difficult probabi­li­ty theory issue, yet the visuals should enable courts and juries to handle it. The Puckett facts are an example of a general approach: A search in a large DNA database produces a hit for a cold crime from 1972 San Francisco. Probability theory allows us to process the probabilities that someone else in the database, someone not in the database, or …

The Hallmark Of A Champion—Or Not, Robert Sanger

Robert M. Sanger

Two decisions that just came down, one from the United States Supreme Court and the other from the California Supreme Court. The former is Hall v. Florida and the latter is In re Champion on Habeas Corpus. The Hall and Champion cases, although they do not cite each other, both discuss significant issues with regard to who is eligible for execution under the Atkins decision.

Hall and Champion perpetuate the myth that capital punishment can be imposed accurately and consistently. Additionally, both cases contain serious errors in interpreting science while suggesting that life and death decisions can be based on …

Using Video Link To Take Forensic Evidence - Lessons From An Australian Case Study, Anne Wallace

Anne Wallace Professor

This article examines the use of audio-visual communications technology (specifically, video link) to enable courts to receive forensic evidence in criminal cases. It outlines the legislative powers to take evidence via video link in Australia, identifying their broad discretionary nature, and analysing relevant case law on their interpretation. The article then discusses empirical findings from an Australian case study in a jurisdiction where a police forensic service has a policy to promote the use of this technology to take evidence from its staff. The findings suggest that, although the policy has had some success in influencing the approach of courts …

The Importance Of Being Empirical, Michael Heise

Michael Heise

Legal scholarship is becoming increasingly empirical. Although empirical methodologies gain important influence within the legal academy, their application in legal research remains underdeveloped. This paper surveys and analyzes the state of empirical legal scholarship and explores possible influences on its production. The paper advances a normative argument for increased empirical legal scholarship.

Dumping Daubert, Popping Popper And Falsifying Falsifiability: A Re-Assessment Of First Principles, Barbara P. Billauer Esq

barbara p billauer esq

Abstract: The Daubert mantra demands that judges, acting as gatekeepers, prevent para, pseudo or bad science from infiltrating the courtroom. To do so, the Judges must first determine what is ‘science’ and what is ‘good science.’ It is submitted that Daubert is deeply polluted with the notions of Karl Popper who sets ‘falsifiability’ and ‘falsification’ as the demarcation line for that determination. This philosophy has intractably infected case law, leading to bad decisions immortalized as stare decisis, and an unworkable system of decision-making, which negatively impacts litigant expectations. Among other problems is the intolerance of Popper’s system for multiple causation, …

Managing Big Data In Complex Litigation, Robert Sanger

Robert M. Sanger

Any lawyer doing complex litigation, civil or criminal, has confronted what seems like an insurmountable sea of data. Many of us have used computer relational database programs and otherwise fought through the mass of information to prepare to try a case. There have been some advancements in managing data made by law enforcement in recent years to make their investigations manageable. During law enforcement investigations, the goal is somewhat different than that of the lawyer preparing for trial; however, the concepts are useful.

Systemic Lying, Julia Simon-Kerr

Julia Simon-Kerr

This Article offers the foundational account of systemic lying from a definitional and theoretical perspective. Systemic lying involves the cooperation of multiple actors in the legal system who lie or violate their oaths across cases for a consistent reason that is linked to their conception of justice. It becomes a functioning mechanism within the legal system and changes the operation of the law as written. By identifying systemic lying, this Article challenges the assumption that all lying in the legal system is the same. It argues that systemic lying poses a particular threat to the legal system. This means that …

Inefficient Evidence, Alex Stein

Alex Stein

Why set up evidentiary rules rather than allow factfinders to make decisions by considering all relevant evidence? This fundamental question has been the subject of unresolved controversy among scholars and policymakers since it was raised by Bentham at the beginning of the nineteenth century. This Article offers a surprisingly straightforward answer: An economically minded legal system must suppress all evidence that brings along a negative productivity-expense balance and is therefore inefficient. Failure to suppress inefficient evidence will result in serious diseconomies of scale. To operationalize this idea, I introduce a “signal-to-noise” method borrowed from statistics, science, and engineering. This method …

The New Doctrinalism: Implications For Evidence Theory, Alex Stein

Alex Stein

This Article revisits and refines the organizing principles of evidence law: case specificity, cost minimization, and equal best. These three principles explain and justify all admissibility and sufficiency requirements of the law of evidence. The case-specificity principle requires that factfinders base their decisions on the relative plausibility of the stories describing the parties’ entitlement–accountability relationship. The cost-minimization principle demands that factfinders minimize the cost of errors and the cost of avoiding errors as a total sum. The equal-best principle mandates that factfinders afford every person the maximal feasible protection against risk of error while equalizing that protection across the board. …

Law, Science, And The Economy: One Domain?, David S. Caudill

David S Caudill

In an effort to explore the theoretical and practical promise of ignoring or erasing conventional boundaries and distinctions—such as law/society or inside/outside—in accounts of legal processes and institutions, I consider the problem of financial bias in scientific expertise. I first draw an analogy with science studies, and particularly Latour’s notion of science as a coproduction, which challenges the boundaries (i) between science and society, and (ii) between natural and social influences on the production of scientific knowledge. I then acknowledge the efforts of Philip Mirowski, in his concern that privatization trends degrade science, to overcome an individualistic perspective on financial …
