Frye Motion: A Comprehensive Guide to Its Legal Definition and Application

Definition & Meaning

The Frye motion refers to a legal request made during a trial to exclude certain scientific evidence from being presented to the jury. This motion is based on the Frye standard, established in the case of Frye v. United States (1923), which requires that scientific evidence must be generally accepted within the relevant scientific community before it can be admitted in court. The aim of the Frye motion is to ensure that only reliable and widely recognized scientific methods are considered in legal proceedings.

Real-world examples

Here are a couple of examples of abatement:

Example 1: In a criminal case involving a defendant accused of murder, the prosecution wants to introduce DNA evidence obtained through a new testing method. The defense may file a Frye motion to challenge the admissibility of this evidence, arguing that the method has not gained general acceptance among forensic scientists.

Example 2: A civil lawsuit regarding a defective product may involve expert testimony about the safety of a new material. The defendant could file a Frye motion to exclude this testimony if it is based on an unproven scientific theory (hypothetical example).
