Polygraph examination by John Grogan allowed in as evidence by Judge

A polygraph examination administered by polygrapher John Grogan was allowed in as evidence by the judge overseeing the case, despite the objection of the other side to polygraph evidence.

While polygraph exams are often allowed in as evidence by stipulation (when both sides agree in advance), this exam was not agreed to.

Thus the judge had to decide. Grogan was interviewed for a full day by one side's attorney, about not just his 25 years of polygraph experience but also about the polygraph profession & history, in detail. Then the other side's attorney cross-examined Grogan for an entire day, hoping to exclude polygraph evidence.

The judge quickly decided that Grogan was knowledgeable and credible and that polygraph is reliable, and allowed the polygraph report to stand as evidence.
