Confirms NC Supreme Court held polygraph evidence inadmissible in all trials, even upon stipulation, decided March 8, 1983, and that ruling does not affect investigative use.

Subsequent cases have reinforced this rule. In State v. Fleming (350 N.C. 109, 1999), the court properly prohibited the defendant from offering polygraph test results [25]Verified Polygraphs, Plethysmography, and Witness Credibility — NC PRO (UNC School of Government)

Polygraph for Investigative Purposes Remains Permitted

The Grier court explicitly stated that its ruling does not affect the use of the polygraph for investigatory purposes [17]Verified State v. Grier, 307 N.C. 628 (1983)
Confirms NC Supreme Court held polygraph evidence inadmissible in all trials, even upon stipulation, decided March 8, 1983, and that ruling does not affect investigative use [26]Verified Evidence — Polygraph Test Results No Longer Admissible in North Carolina (Campbell Law Review)
Confirms State v. Grier expressly overruled State v. Steele and State v. Milano, establishing per se inadmissibility rule. Law enforcement officers are still permitted to use polygraph testing as an investigative tool. Suspects may confess or make incriminating statements during or after polygraph testing, and such statements or admissions are not inadmissible merely because they were made in connection with a polygraph — as long as the actual test results are not presented to the jury [25]Verified Polygraphs, Plethysmography, and Witness Credibility — NC PRO (UNC School of Government)
Confirms polygraph testing remains permitted for investigative purposes, statements made during testing remain admissible, and cites State v. Grier, State v. Fleming, and State v. Harris precedents.

In State v. Harris (315 N.C. 556, 1986), the court held that a defendant's confession made after failing a polygraph was admissible, noting that the administration of the polygraph test was merely an event bearing on the total circumstances surrounding the defendant's inculpatory statement [25]Verified Polygraphs, Plethysmography, and Witness Credibility — NC PRO (UNC School of Government)
Confirms polygraph testing remains permitted for investigative purposes, statements made during testing remain admissible, and cites State v. Grier, State v. Fleming, and State v. Harris precedents. This distinction between investigative use and evidentiary admissibility is an important consideration for both private polygraph testing in North Carolina and law enforcement applications.
