When the Truth Prevails: The Myth About Polygraph Test Admissibility in Court
In this blog, we will address two powerful truths. First, that false accusations do not always prevail when facts and evidence are properly presented. Second, that the long-standing myth that polygraph testing is never admissible in court is simply not accurate.
There is widespread confusion surrounding the admissibility of polygraph test results. While courts have discretion in every case, polygraph examinations can be admitted into evidence under certain legal standards and circumstances.
Important Clarification for Readers
Throughout this blog, the terms polygraph test, polygraph examination, and lie detector test are used interchangeably. They refer to the same professional process. Historically, the public was more familiar with the term “lie detector test.” Today, the more accurate and professional term is “polygraph examination.”
A Note on Court Discretion
Every state and every court maintains its own legal standards regarding the admissibility of evidence. The presiding judge in each case ultimately determines whether a polygraph examination will be admitted.
However, judicial discretion does not mean that polygraph testing is automatically inadmissible. The claim that polygraph results are “never allowed in court” is a misconception. With the right legal strategy and a solid foundation in case law, polygraph evidence can be admitted.
A Real Case Example
The following case is a true account. Names have been changed to protect the individuals involved.
In June 2021, a 16-year-old female, whom we will refer to as “Unique,” made allegations against her stepfather, whom we will call “Justice.” According to family members and subsequent interviews, Unique had a history of behavioral challenges and conflict within the household.
Several months after a disciplinary incident involving the confiscation of her phone, Unique alleged that she had been sexually abused by her stepfather. The allegation was not reported immediately but surfaced months later during a period of emotional conflict.
During a comprehensive pre-test interview, Unique provided a detailed narrative of the alleged incident. A professionally administered polygraph examination was conducted specifically addressing those allegations. The examination indicated deception regarding the claims.
At the time of the original examination, there was no involvement from Child Protective Services, no law enforcement investigation, and no criminal charges filed.
Years later, after reaching adulthood, Unique reported the allegations to law enforcement. Charges were filed against Justice
The Court Proceedings
In November 2024, the case proceeded to trial. The defense attorney, Mr. Jeffrey Swartz, a seasoned and highly experienced defense attorney, presented extensive testimony and legal arguments.
Using established case law, the defense successfully moved to admit the polygraph examination into evidence. The court accepted the polygraph results without stipulation.
As the administering polygraph examiner, I testified regarding the procedures used, the statements made during the examination, and the results obtained.
After full presentation of evidence and testimony, the jury returned a verdict of Not Guilty.
What This Case Demonstrates
This case does not suggest that every polygraph examination will be admitted into evidence. Nor does it imply that every court will accept such testimony. However, it clearly demonstrates that the blanket statement “polygraphs are not admissible in court” is inaccurate.
Polygraph test admissibility in court depends on:
The jurisdiction
The judge’s discretion
The legal strategy employed
The qualifications of the examiner
The credibility of the foundation laid by counsel
When properly handled by a qualified, court-certified polygraph examiner and an experienced defense attorney, polygraph evidence can play a role in the judicial process.
Why Examiner Qualifications Matter
Not all polygraph examiners are qualified to testify in court. Courtroom admissibility often depends on:
Advanced certification
Documented training
Established methodology
Professional experience
Courtroom testimony history
An inexperienced examiner without proper credentials or courtroom experience can weaken a case rather than strengthen it.
If you are facing false allegations or serious legal consequences, the qualifications of the polygraph examiner you choose matter significantly.
The Truth Can Prevail in Court
False accusations can have life-altering consequences. The legal process can be overwhelming, costly, and emotionally devastating.
However, truth supported by proper procedure, credible evidence, and experienced legal representation can prevail.
If you or someone you know is facing allegations and considering a polygraph test, ensure that the examination is conducted by a highly qualified, court-experienced polygraph examiner and coordinated with competent legal counsel.
