Toward A Child-Centered Approach To Evaluating Claims Of Alienation In High-Conflict Custody Disputes, Allison M. Nichols Feb 2014

Toward A Child-Centered Approach To Evaluating Claims Of Alienation In High-Conflict Custody Disputes, Allison M. Nichols

Michigan Law Review

Theories of parental alienation abound in high-conflict custody cases. The image of one parent brainwashing a child against the other parent fits with what we think we know about family dynamics during divorce. The concept of a diagnosable “Parental Alienation Syndrome” (“PAS”) developed as an attempt to explain this phenomenon, but it has been widely discredited by mental health professionals and thus fails the standard for evidentiary admissibility. Nevertheless, PAS and related theories continue to influence the decisions of family courts, and even in jurisdictions that explicitly reject such theories, judges still face the daunting task of resolving these volatile …


Torts And Innovation, Gideon Parchomovsky, Alex Stein Nov 2008

Torts And Innovation, Gideon Parchomovsky, Alex Stein

Michigan Law Review

This Essay exposes and analyzes a hitherto overlooked cost of tort law: its adverse effect on innovation. Tort liability for negligence, defective products, and medical malpractice is determined by reference to custom. We demonstrate that courts' reliance on custom and conventional technologies as the benchmark of liability chills innovation and distorts its path. Specifically, recourse to custom taxes innovators and subsidizes replicators of conventional technologies. We explore the causes and consequences of this phenomenon and propose two possible ways to modify tort law in order to make it more welcoming to innovation.


Dna As Evidence: Viewing Science Through The Prism Of The Law, Peter Donnelly, Richard D. Friedman Jan 2000

Dna As Evidence: Viewing Science Through The Prism Of The Law, Peter Donnelly, Richard D. Friedman

Articles

In this article, we analyze a problem related to DNA evidence that is likely to be of great and increasing significance in the near future. This is the problem of whether, and how, to present evidence that the suspect has been identified through a DNA database search. In our view, the two well-known reports on DNA evidence issued by the National Research Council (NRC) have been badly mistaken in their analysis of this problem. The mistakes are significant because the reports have carried great authority with American courts; moreover, the DNA Advisory Board of the FBI has endorsed the second …

Dna Database Searches And The Legal Consumption Of Scientific Evidence, Peter Donnelly, Richard D. Friedman

Articles

DNA evidence has transformed the proof of identity in criminal litigation, but it has also introduced daunting problems of statistical analysis into the process. In this Article, we analyze a problem related to DNA evidence that is likely to be of great and increasing significance in the near future. This is the problem of whether, and how, to present evidence that the suspect has been identified through a DNA database search. In our view, the two well-known reports on DNA evidence issued by the National Research Council ("NRC"), each of which has carried great authority with the American courts on …


The Death And Transfiguration Of Frye, Richard D. Friedman Jan 1994

The Death And Transfiguration Of Frye, Richard D. Friedman

Articles

The rule of Frye v. United States was seventy years old, and had long dominated American law on the question of how well established a scientific principle must be for it to provide the basis for expert testimony. Even after the passage of the Federal Rules of Evidence, several of the federal circuits, as well as various states, purported to adhere to Frye's "general acceptance" standard. But now, unanimously, briefly, and with no apparent angst, the United States Supreme Court has held in Daubert v. Merrell Dow Pharmaceuticals, Inc. that the Frye rule is incompatible with the Federal Rules.
