On March 31, 1998 the US Supreme Court issued a ruling (United States v. Scheffer, 523 US 303 (1998)) that overturned a case involving polygraph evidence. However, their decision did not completely disallow the use of polygraphs as admissible evidence in criminal trials. The justices ruled (in a split decision) that state and federal governments MAY ban the use of polygraph evidence in court, declaring that doubts and uncertainties remain about the accuracy of the so-called lie-detector tests. It should be noted that the operative word in the decision is MAY and not SHALL.
