Subject to subsection (2), a reference in this Chapter to the relevance or probative value of evidence is a reference to its relevance or probative value on the assumption that it is true.
In assessing the relevance or probative value of an item of evidence for any purpose of this Chapter, a court need not assume that the evidence is true if it appears, on the basis of any material before the court (including any evidence it decides to hear on the matter), that no court or jury could reasonably find it to be true.
