The Dna Of An Argument: A Case Study In Legal Logos, Colin Starger Jul 2009

The Dna Of An Argument: A Case Study In Legal Logos, Colin Starger

All Faculty Scholarship

This Article develops a framework for analyzing legal argument through an in-depth case study of the debate over federal actions for post-conviction DNA access. Building on the Aristotelian concept of logos, this Article maintains that the persuasive power of legal logic depends in part on the rhetorical characteristics of premises, inferences, and conclusions in legal proofs. After sketching a taxonomy that distinguishes between prototypical argument logo (formal, empirical, narrative, and categorical), the Article applies its framework to parse the rhetorical dynamics at play in litigation over post-conviction access to DNA evidence under 42 U.S.C. § 1983, focusing in particular on …


"False But Highly Persuasive": How Wrong Were The Probability Estimates In Mcdaniel V. Brown?, David H. Kaye Jan 2009

"False But Highly Persuasive": How Wrong Were The Probability Estimates In Mcdaniel V. Brown?, David H. Kaye

Michigan Law Review First Impressions

In McDaniel v. Brown, the Supreme Court will review the use of DNA evidence in a 1994 trial for sexual assault and attempted murder. The Court granted certiorari to consider two procedural issues—the standard of federal postconviction review of a state jury verdict for sufficiency of the evidence, and the district court's decision to allow the prisoner to supplement the record of trials, appeals, and state postconviction proceedings with a geneticist's letter twelve years after the trial. The letter from Laurence Mueller, a professor at the University of California at Irvine, identified two obvious mistakes in the state's expert testimony. …

Rounding Up The Usual Suspects: A Logical And Legal Analysis Of Dna Trawling Cases, David H. Kaye

Journal Articles

Courts are beginning to confront a problem that has divided the scientific community - whether identifying a defendant by fishing through a database of DNA types to find a match to a crime-scene sample reduces the significance of a match. For years, the problem seemed academic. Now that the U.S. has more than five million DNA profiles from convicted offenders and suspects in a national, computer-searchable database, the question has assumed more urgency. Increasingly, individuals are being charged with crimes as a result of a match between their recorded profile and the DNA from a victim or scene of a …

On Race Theory And Norms, Christian Sundquist Jan 2009

On Race Theory And Norms, Christian Sundquist

Articles

This article has been adapted from an address given at the Albany Law Review Symposium in Spring 2009. This article discusses the judicial acceptance of DNA random match estimates, which uses DNA analysis to estimate the likelihood that a criminal defendant is the source of genetic material that is found at a crime scene. Relying on race, these tests demonstrate how such a re-inscription of race as a biological entity threatens the modern conception of race as a social construction, and how those estimates should be rejected as inadmissible on a doctrinal level under the Federal Rules of Evidence.
