Is the polygraph examination admissible in court?
It depends. Some courts have allowed the introduction of polygraph evidence while others have not. Each jurisdiction must be checked to determine admissibility standards. One of the greatest fears keeping polygraph evidence out of courts is the fact that such evidence would carry greater weight than other equally-important evidence and would tend to sway a jury in one direction even though other evidence may point the other way. In most cases, polygraph evidence is used during pretrial negotiations, administrative hearings, and during sentencing rather than during the trial itself.
