Alaska Supreme Court rules that polygraphs can no longer be used as evidence

By  | 

FAIRBANKS, Alaska - The Alaska Supreme Court has ruled that polygraph tests cannot be used as evidence in court. A 1970 Supreme Court ruling forbade prosecutors from using them. This ruling extends the ban to the defense. The court found that polygraph tests fail to satisfy the standard of scientific evidence.

The action comes after lower courts were in disagreement over three cases involving admitting polygraphs as evidence. The Supreme Court's decision overturned the ruling of two of the lower courts and affirmed the ruling of another.
