Rule 303 - Presumptions In Criminal Cases(a) Scope. Except as otherwise provided by statute, in criminal cases, presumptions against an accused, recognized at common law or created by statute, including statutory provisions that certain facts are prima facie evidence of other facts or of guilt, are governed by this rule.(b) Submission to Jury. The court is not authorized to direct the jury to find a presumed fact against the accused. If a presumed fact establishes guilt or is an element of the offense or negatives a defense, the court may submit the question of guilt or of the existence of the presumed fact to the jury, but only if a reasonable juror on the evidence as a whole, including the evidence of the basic facts, could find guilt or the presumed fact beyond a reasonable doubt. If the presumed fact has a lesser effect, the question of its existence may be submitted to the jury provided the basic facts are supported by substantial evidence or are otherwise established, unless the court determines that a reasonable juror on the evidence as a whole could not find the existence of the presumed fact.
