South Dakota state law cannot govern the admissibility of polygraph evidence in federal courts. Under the Daubert Standard (http://en.wikipedia.org/wiki/Daubert), polygraph evidence may be admissible in federal trials. You'll find summaries of some recent federal cases where polygraph admissibility was at issue here:
