Polygraph is used extensively by attorneys who wish to provide
the best possible defense for their clients. Most attorneys will submit their
own clients to the exam, while others will use the polygraph to verify statements
made by witnesses and other parties to litigation. Now known as Psychophysiological
Detection of Deception (PDD), an experienced examiner can provide evidence
in connection with any type of criminal or civil matter. Our examiners have
a great deal of experience working with attorneys, both in private and government
practice, and have aided thousands of clients in preparing defenses that would
otherwise have been unavailable to them.
With the recent establishment of polygraph
standards by ASTM, polygraph has gained great strides in credibility
with the scientific community. These standards, approved by a combined body
of experts, now provide a template for the increased acceptabilty of polygraph
Contrary to popular belief, polygraph is not per-se inadmissible in
court proceedings. Admissibility standards are different in each jurisdiction.
Some jurisdictions allow polygraph evidence, either stipulated or un-stipulated,
some prohibit polygraph evidence altogether, and many others allow the
judge to decide admissibility on a case-by-case basis. The Daubert case is
presently the standard for the admission of scientific evidence, which includes
polygraph. In reality, most polygraph results are used outside of the courtroom
in pre-trial negotiations, plea bargaining, sentence recommendations, and witness
verification or impeachment.
We also have experts on staff who can provide
testimony regarding polygraphic evidence administered by other examiners,
and who can provide testimony regarding scientific credibility of polygraph.
