Polygraph Law Resource Page

[This page is no longer being updated.]

Following Daubert most of the Federal Courts and many of the state courts have revisited the issue of admitting the results of polygraph tests as evidence in courts of law. This page was created as a resource for those legal and polygraph professionals who are interested in this topic.

No claim was made to have been comprehensive. What is collected here are materials that were on hand and jumps to important materials of which I wasaware.

The Supreme Court of the United States


In United States v. Scheffer (Cite as 44 MJ, 442) a decision by the United States Court of Appeals for the Armed Forces concluded that the President Bush's executive order that made all polygraph evidence inadmissible in the military courts was unconstitutional, at least as concerns defendants. This opened the door for the admissibility of polygraph in the military courts and essentially returns matters to state of affairs following U. S. v. Gipson 24 M.J. 246 (C. M. A. 1987). The proponent of the polygraph evidence must provide a scientific foundation showing that the evidence is reliable under Daubert.

Unfortunately the case was appealed to the United States Supreme Court. The Court produced a complex decision that has some negative and some positive elements. The complete opinion can be accessed below.

An ad hoc Committee of Concerned Scientists prepared an amicus brief concerning the science of the polygraph. A draft of the Amicus is available at the previous hyperlink The PDF version of the final brief is posted below.

United States Court of Appeals' Decisions on the Polygraph

The 5th Circuit

United States v. Posado A decision that does away with the per se inadmissibility rule. The Court states, "... we have today opened the door to the possibility of polygraph evidence in certain circumsatnces."

The 9th Circuit

United States v. Cordoba This is a very recent decision from the 9th Circuit overturning the per se rule excluding the admission of unstipulated polygraph evidence. The opinion contains a good summary of the important recent Court of Appeals' decisions on the polygraph. The version stored here is a mirror of the original Internet version which is available at The Villanova Center for Information and Policy.

United States v. William Galbreth: This case resulted in a Memorandum Opinion and Order (908 F.Supp. 877) admitting a defense offered polygraph over the objection of the government. David C. Raskin, Ph. D. and Charles R. Honts, Ph. D. testified as expert witnesses for the defense. Lawrence Farwell, Ph. D. and Gordon H. Barland, Ph. D. testified as expert witnesses for the government. We are working on the Memorandum Opinion and Order and will have it available shortly. I know that it can be retrieved through WESTLAW if you have access to that service.

Dr. Raskin's foundational testimony and cross-examination is quite long and it has been divided into three files so the download time will not be so long.

Raskin Vol. 1 March 9, 1995

Raskin Vol. 2 March 9, 1995

Raskin Vol. 3 March 9, 1995

Lawrence Farwell, Ph. D. March 10, 1995 / Following a blistering voir dire by Charles Daniels during the qualification phase, Dr. Farwell was not qualified as an expert and was not allowed to testify further.

Gordon H. Barland, Ph. D., March 10, 1995

Charles R. Honts, Ph. D., March 10, 1995

The case of Brent Anthony Richter v. Ron Bartee, Chariman of the Nebraska Board of Parole, et al., This transcript shows what I believe to be a very effective cross-examination of and rebuttal to a police polygraph examiner. The judge seemed to agree. There is a newspaper article about the case at the end of the Memorandum and Order.

Papers on Polygraph Admissibility Issues

A paper presented in May 1997 at the American Psychological Society meetings in Washington D.C. This paper addresses and rejects the notion that polygraph examinations conducted in private for a defense attorney are, in general, less valid than examinations conducted for law enforcement.

Is It Time to Reject The Friendly Polygraph Examiner Hypothesis?
