Quick Summary
James Alphonzo Frye (defendant) was convicted of second-degree murder and appealed his conviction based on the exclusion of expert testimony regarding a ‘systolic blood pressure deception test.’ The United States Court of Appeals for the D.C. Circuit heard the appeal.
The dispute centered on whether the results of this test were admissible as expert evidence. The main issue was the scientific acceptance of the deception test as a reliable method. The court concluded that the test lacked sufficient recognition in its field to be admissible in court.
Facts of the Case
James Alphonzo Frye (defendant) was on trial for second-degree murder. During the trial, Frye’s defense team attempted to introduce testimony from an expert on a ‘systolic blood pressure deception test,’ which was administered to Frye. The defense claimed that this test could determine whether Frye was being truthful based on changes in his blood pressure during questioning.
The trial court, however, did not allow the expert’s testimony about the test results. Subsequently, Frye was convicted. His defense team appealed the decision, challenging the exclusion of the expert witness’s testimony on the deception test.

I.R.A.C. Format
Issue
Whether the systolic blood pressure deception test results are admissible as expert testimony in a court of law under Evidence Law principles.
Rule of Law
Expert opinions are admissible when the subject matter is outside the common knowledge of laypersons and requires specialized experience or knowledge in a scientific, art, or trade field that has gained general acceptance in its particular field.
Reasoning and Analysis
The court analyzed the admissibility of expert testimony based on the ‘Frye Test,’ which assesses whether the scientific principle or discovery from which an expert’s deduction is made has gained general acceptance in its field. The court emphasized that for expert testimony to be admitted, the underlying scientific theory or technique must be widely recognized by experts in that particular discipline.
In Frye’s case, the court determined that the systolic blood pressure deception test had not achieved such recognition among physiological and psychological authorities. Therefore, it did not meet the standard required for admitting scientific evidence in court proceedings.
The court highlighted that although courts are generally open to admitting expert testimony derived from well-established scientific principles, those principles must have crossed over from experimental to demonstrable stages with widespread acceptance within their respective fields.
Conclusion
The appeal court affirmed the trial court’s decision, concluding that the systolic blood pressure deception test lacked sufficient scientific acceptance to warrant admission as expert testimony in Frye’s murder trial.
Key Takeaways
- The ‘Frye Test’ is a crucial standard for determining the admissibility of expert testimony based on scientific evidence; it requires that the evidence has gained general acceptance in its relevant field.
- Scientific evidence that does not meet this standard of general acceptance is not admissible in court as expert testimony.
- The court’s decision in Frye v. United States set a precedent for evaluating scientific techniques and their admissibility in legal proceedings.
