Analysing the law of evidence, this book includes essential doctrinal analysis. It takes an account of evidence theory, psychological research on information processing and retrieval, socio-legal work on police investigations, and jury research projects. It reviews changes to the law, brought about by the Criminal Justice Act 2003.

"As Gary Lawson shows, legal claims are inherently objects of proof, and whether or not the law acknowledges the point openly, proof of legal claims is just a special case of the more general norms governing proof of any claim. As a result, similar principles of evidentiary admissibility, standards of proof, and burdens of proof operate, and must operate, in the background of claims about the law. This book brings these evidentiary principles for proving law out of the shadows so that they can be analyzed, clarified, and discussed."--Amazon website.

Bridging law, genetics, and statistics, this book is an authoritative history of the long and tortuous process by which DNA science has been integrated into the American legal system. In a history both scientifically sophisticated and comprehensible to the nonspecialist, David Kaye weaves together molecular biology, population genetics, the legal rules of evidence, and theories of statistical reasoning as he describes the struggles between prosecutors and defense counsel over the admissibility of genetic proof of identity. Combining scientific exposition with stories of criminal investigations, scientific and legal hubris, and distortions on all sides, Kaye shows how the adversary system exacerbated divisions among scientists, how lawyers and experts obfuscated some issues and clarified others, how probability and statistics were manipulated and misunderstood, and how the need to convince lay judges influenced the scientific research. Looking to the future, Kaye uses probability theory to clarify legal concepts of relevance and probative value, and describes alternatives to race-based DNA profile frequencies. Essential reading for lawyers, judges, and expert witnesses in DNA cases, The Double Helix and the Law of Evidence is an informative and provocative contribution to the interdisciplinary study of law and science.

Identifies and evaluates the psychological choices implicit in the rules of evidence Evidence law is meant to facilitate trials that are fair, accurate, and efficient, and that encourage and protect important societal values and relationships. In pursuit of these often-conflicting goals, common law judges and modern drafting committees have had to perform as amateur applied psychologists. Their task has required them to employ what they think they know about the ability and motivations of witnesses to perceive, store, and retrieve information; about the effects of the litigation process on testimony and other evidence; and about our capacity to comprehend and evaluate evidence. These are the same phenomena that cognitive and social psychologists systematically study. The rules of evidence have evolved to restrain lawyers from using the most robust weapons of influence, and to direct judges to exclude certain categories of information, limit it, or instruct juries on how to think about it. Evidence law regulates the form of questions lawyers may ask, filters expert testimony, requires witnesses to take oaths, and aims to give lawyers and factfinders the tools they need to assess witnesses’ reliability. But without a thorough grounding in psychology, is the “common sense” of the rulemakers as they create these rules always, or even usually, correct? And when it is not, how can the rules be fixed? Addressed to those in both law and psychology, The Psychological Foundations of Evidence Law draws on the best current psychological research-based knowledge to identify and evaluate the choices implicit in the rules of evidence, and to suggest alternatives that psychology reveals as better for accomplishing the law’s goals.

Written from an advocate's perspective, this guide introduces how the courtroom operates and offers a glimpse into the environment that influences these rulings. Major cases and doctrines are discussed. Examples are given to develop a feel for the context in which a particular evidence problem might arise-and for the language lawyers and judges use to resolve it. Also explores the rationale and purpose behind each rule.

This book examines systematically the underlying theory of evidence in Anglo-American legal systems and identifies the defining characteristics of adjudicative fact-finding. Stein develops a detailed innovative theory which sets aside the traditional vision of evidence law as facilitating the discovery of the truth. Combining probability theory, epistemology, economic analysis, and moral philosophy; he argues instead that the fundamental purpose of evidence law is to apportion the risk oferror in conditions of uncertainty. Stein begins by identifying the domain of evidence law.He then describes the basic traits of adjudicative fact-finding and explores the epistemological foundations of the concept. This discussion identifies the problem of probabilistic deduction that accompanies generalizations to which fact-finders resort. This problem engenders paradoxes which Stein proposes to resolve by distinguishing between probability and weight. Stein advances the principle of maximal individualization that does not allow factfinders to make a finding against a person when the evidence they use is not susceptible to individualized testing.He argues that this principle has broad application, but may still be overridden by social utility. This analysis identifies allocation of the risk of error as requiring regulation by evidence law. Advocating a principled allocation of the risk of error, Stein denounces free proof for allowing individual judges to apportion this risk asthey deem fit.He criticizes the UK's recent shift to a discretionary regime on similar grounds. Stein develops three fundamental principles for allocating the risk of error: the cost-efficiency principle which applies across the board; the equality principle which applies in civil litigation; and the equal best principle which applies in criminal trials. The cost-efficiency principle demands that fact-finders minimize the total cost of errors and error-avoidance.Under the equality principle,fact-finding procedures and decisions must not produce an unequal apportionment of the risk of error between the claimant and the defendant. This risk should be apportioned equally between the parties. The equal best principle sets forth two conditions for justifiably convicting and punishing a defendant. The state must do its best to protect the defendant from the risk of erroneous conviction and must not provide better protection to other individuals. Regulating both the admissibility of evidence and its sufficiency, these principles explain and justify many existing evidentiary rules. Alex Stein is Professor of Law at the Benjamin N.Cardozo School of Law,New York.

Winner of the Scribes Book Award “Displays a level of intellectual honesty one rarely encounters these days...This is delightful stuff.” —Barton Swaim, Wall Street Journal “At a time when the concept of truth itself is in trouble, this lively and accessible account provides vivid and deep analysis of the practices addressing what is reliably true in law, science, history, and ordinary life. The Proof offers both timely and enduring insights.” —Martha Minow, former Dean of Harvard Law School “His essential argument is that in assessing evidence, we need, first of all, to recognize that evidence comes in degrees...and that probability, the likelihood that the evidence or testimony is accurate, matters.” —Steven Mintz, Inside Higher Education “I would make Proof one of a handful of books that all incoming law students should read...Essential and timely.” —Emily R. D. Murphy, Law and Society Review In the age of fake news, trust and truth are hard to come by. Blatantly and shamelessly, public figures deceive us by abusing what sounds like evidence. To help us navigate this polarized world awash in misinformation, preeminent legal theorist Frederick Schauer proposes a much-needed corrective. How we know what we think we know is largely a matter of how we weigh the evidence. But evidence is no simple thing. Law, science, public and private decision making—all rely on different standards of evidence. From vaccine and food safety to claims of election fraud, the reliability of experts and eyewitnesses to climate science, The Proof develops fresh insights into the challenge of reaching the truth. Schauer reveals how to reason more effectively in everyday life, shows why people often reason poorly, and makes the case that evidence is not just a matter of legal rules, it is the cornerstone of judgment.
