DNA inputting introduces two important matters for judges. First the judge must decide if the DNA is admissible and then the jurors must understand the proper requirement for "weighing" evidence (National Research Council). There are two principles on which DNA is decided for as admissible or not. First the Frye test and the other is "helpfulness." The Frye test came about from the case Frye v. United States. In 1923, the defendant proposed to use the lie detector test as evidence as to clear his name as to whether or not he had killed the victim. The courts ruled that the lie detector test was inadmissible because the "scientific principles upon which the procedure was based were not sufficiently established to have gained general acceptance in the particular field in which it belongs (US Legal)." The Supreme Court of Minnesota, in November 1989,
