Relevance of collateral facts: evidence that alters the probability of a fact in issue is admissible and probative. Facts not otherwise relevant are relevant if they are inconsistent with any fact in issue or relevant fact, or if by themselves or with other facts they make the existence or non existence of any fact in issue or relevant fact highly probable or highly improbable; illustrations include alibi evidence showing an accused was at a distant location and facts excluding other possible perpetrators.
