United States Court of Appeals for the D.C. Circuit
293 F. 1013 (D.C. Cir. 1923)
Frye (defendant) was charged with second-degree murder. At trial, Frye’s counsel sought to introduce an expert who would testify as to a “systolic blood pressure deception test” that the expert performed on Frye. The test would allegedly show whether Frye was lying when he testified because blood pressure allegedly rises when a person lies but stays the same when the person told the truth. The trial court rejected the testimony of the expert. Frye was convicted and appealed.
