Wrongfully accused and need a lie detector test? 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 1998 establishment of polygraph (Forensic Psychophysiology) 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 acceptability of polygraph results.
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, although some jurisdictions still rely on the older Frye standard. In reality, most polygraph results are used outside of the courtroom in pre-trial negotiations, plea bargaining, sentence recommendations, and witness verification or impeachment.
Civil and family courts are more flexible when allowing polygraph evidence, as the admissibility requirements in these venues do not need to meet the Daubert or Frye standards.
