Polygraph results fail to conform to the Frye doctrine and are therefore inadmissible as evidence in court. This doctrine, enunciated in Frye v. United States (1923) states that, before the results of scientific tests will be admissible as evidence in a trial, the procedures used must be sufficiently established to have gained general acceptance in the particular field to which they belong. Most courts refuse to admit the results of polygraph (lie detector) tests in either civil or criminal proceedings unless admissibility is agreed to by both parties.
Polygraph results are frequently used in other situations, such as pre-employment or background tests. If this is the case, it begs the question of why these results should be excluded from courtrooms.
For this assignment, prepare a three-page memorandum to your supervisor, an attorney, addressing the admissibility of polygraph results.
In your memorandum:
- Analyze the current position of the U.S. Supreme Court with respect to reliability and admissibility of polygraph evidence.
- Determine the potential impact of Frye v. United States on criminal cases.
Be sure to review the Polygraph Results Scoring Guide to ensure you understand the criteria for this assignment.
Your memorandum should meet the following requirements:
- Written communication: Must be free of errors that detract from the overall message.
- References: A minimum of two references.
- APA format: Format resources and citations as per current APA style and formatting guidelines.
- Length of memorandum: Three pages, not including the title page and the references page.
- Font and font size: Times New Roman, 12 point.
