One of the first rules to start at with any evidence question, is whether or not the piece of evidence is actually relevant.
This rule defines what relevant evidence is. Relevant evidence means that this piece of evidence makes some fact more probable than not. If the judge finds that the piece of evidence is relevant, then they should go to the next rules to determine if they should allow it into evidence. If it is not relevant, then the judge does not let it in. This rule and the Federal Rule are the same.
