The Frye v. United States case, decided in 1923, is a landmark ruling in the history of American jurisprudence, particularly in the realm of forensic science and the admissibility of expert testimony in court. This case has had a profound impact on the development of legal standards for the admission of scientific evidence and has been a subject of extensive study and debate among legal scholars, scientists, and experts in the field of forensic science.
Background and Context of Frye v. United States
In 1923, James Alphonso Frye was accused of murder in the second degree. As part of his defense, Frye’s attorneys attempted to introduce the results of a systolic blood pressure test, which was a novel technique at the time, designed to detect deception. The test was based on the principle that a person’s blood pressure would rise when they were lying. Frye’s attorneys argued that the results of this test, which indicated that Frye was telling the truth, should be admissible as evidence to support his claim of innocence.
The Court’s Decision and Its Impact
The court, however, ruled that the results of the systolic blood pressure test were not admissible as evidence. In its decision, the court established what has become known as the “Frye standard” or the “general acceptance test” for the admissibility of scientific evidence. The court held that for a scientific principle or discovery to be admissible in court, it must be “sufficiently established to have gained general acceptance in the particular field in which it belongs.” This standard was designed to ensure that only reliable and widely accepted scientific principles and methods were used in the presentation of evidence in court.

Evolution of the Frye Standard and Its Criticisms
Over the years, the Frye standard has undergone significant scrutiny and evolution. Critics have argued that the standard can be overly restrictive, potentially excluding new and innovative scientific techniques from being considered in court. On the other hand, proponents of the standard argue that it provides a necessary safeguard against the admission of unreliable or unproven scientific evidence.
Daubert v. Merrell Dow Pharmaceuticals and the Shift in Admissibility Standards
In 1993, the U.S. Supreme Court’s decision in Daubert v. Merrell Dow Pharmaceuticals marked a significant shift in the standards for the admissibility of scientific evidence. The Daubert decision effectively replaced the Frye standard in federal courts, introducing a more flexible and multifaceted approach to evaluating the reliability and relevance of scientific evidence. The Daubert standard requires that scientific evidence be both relevant and reliable, with the reliability of the evidence being assessed based on factors such as the testability of the scientific theory or principle, the presence of peer review and publication, the known or potential rate of error, and the general acceptance of the technique within the relevant scientific community.
Key Points
- The Frye v. United States case established the "general acceptance test" for the admissibility of scientific evidence in court.
- The Frye standard requires that a scientific principle or discovery be widely accepted within its field to be considered admissible.
- Criticisms of the Frye standard include its potential to exclude new scientific techniques and its broad application.
- The Daubert v. Merrell Dow Pharmaceuticals decision introduced a new standard for the admissibility of scientific evidence, focusing on relevance and reliability.
- The evolution of standards for the admissibility of scientific evidence reflects ongoing efforts to balance the need for reliable evidence with the need to incorporate new scientific discoveries into legal proceedings.
The evolution of the standards for the admissibility of scientific evidence, from the Frye standard to the Daubert standard and beyond, underscores the complex interplay between science, law, and the pursuit of justice. As scientific knowledge and methodologies continue to advance, the legal system must adapt to ensure that the evidence presented in court is both reliable and relevant, ultimately serving the pursuit of truth and justice.
What was the main issue in the Frye v. United States case?
+The main issue in the Frye v. United States case was whether the results of a systolic blood pressure test, designed to detect deception, were admissible as evidence in court.
What is the Frye standard, and how does it relate to the admissibility of scientific evidence?
+The Frye standard, established in the Frye v. United States case, requires that a scientific principle or discovery be sufficiently established to have gained general acceptance in its particular field to be admissible as evidence in court.
How did the Daubert v. Merrell Dow Pharmaceuticals decision change the standards for the admissibility of scientific evidence?
+The Daubert decision introduced a new standard that focuses on the relevance and reliability of scientific evidence, replacing the Frye standard in federal courts and providing a more flexible approach to evaluating the admissibility of scientific evidence.
