This Article examines the issues and questions which underlie the debate over the admission of "medical treatises" into evidence. The admissibility of this type of evidence is at issue most often in litigation involving complex medico-legal issues. This article outlines the evidentiary basis for admission of medical treatises and discusses the quality of medical treatises in an effort to determine what value to the fact-finder these treatises actually hold. The authors contend that there is an inherent untrustworthiness associated with medical treatises, but do not go so far as to suggest that medical treatises should never be admitted. The Article concludes that there is a need for greater caution in determining admissibility and recommends safeguards to better guarantee trustworthiness and reliability.  相似文献

The Equal Employment Opportunity Commission (EEOC) recently issued its final regulations on the Americans with Disabilities Act (ADA). Although the regulations offer some guidance for employers on how to comply with the Act, they fail to provide specific answers to the many complicated compliance questions that will surely arise. Further, the regulations are almost totally silent on certain critical issues related to insurance, workers' compensation, and potential conflicts between ADA obligations and terms of collective bargaining agreements. The EEOC has essentially left the resolution of many important ADA questions to case-by-case determination and the litigation process.  相似文献

Social scientists have increasingly become involved in the submission of amicus curiae or friend of the court briefs in legal cases being decided by state and federal courts. This increase has triggered considerable debate about the use of briefs to communicate relevant social science research. This article evaluates the strengths and weaknesses of various methods of summarizing social science research for the courts. It also reviews the procedures for submitting briefs developed by the American Psychology-Law Society which, in collaboration with the American Psychological Association, has submitted its first brief inMaryland v. Craig, a case recently decided by the U.S. Supreme Court.The authors wish to thank James Ogloff, Kathy Roesch, and Claudia Worrell for their comments on an earlier draft  相似文献

In 1989, after almost two decades of substance-by-substance standard setting, the Occupational Safety and Health Administration (OSHA) promulgated its Air Contaminants Standard, imposing new exposure limits for 376 toxic substances encountered in U.S. industry. In marked contrast to earlier regulations, the Air Contaminants Standard has generated relatively little industry opposition. This paper analyzes the standard in the context of the twenty-year debate over the appropriate role for technological feasibility and economic compliance costs in occupational health policy. The political feasibility of the new standard is traced to OSHA's abandonment of "technology forcing" in favor of reliance on "off-the-shelf" technologies already in use in major firms. While important as an embodiment of OSHA's new "generic" approach to regulation, the Air Contaminants Standard cannot serve as a model for future occupational health policy, due to its reliance on informal, closed-door mechanisms for establishing regulatory priorities and permissible exposure limits.  相似文献

InMaryland v. Craig, the United States Supreme Court relied heavily on a brief prepared by a committee of the American Psychology-Law Society on behalf of the American Psychological Association (APA). The APA brief concluded that sexually abused children may be particularly vulnerable to distress in the legal process, especially when forced to confront the defendant face to face, and that such acute distress may be inconsistent with the state's interests in promotion of reliable testimony and child welfare. APA also argued that psychological theory and research provide foundations for individualized determination of the need for measures to protect children from face-to-face confrontation. *** DIRECT SUPPORT *** AFE06051 00002  相似文献
