One of the basic tenets governing admissibility of evidence at trial is it is a matter within the discretion of the trial judge. Evidence admissibility issues are governed by the abuse of discretion standard on appeal.
Rulings on admissibility will be overturned only when the decision is arbitrary, fanciful or unreasonable and when the improper ruling substantially effects the outcome of the trial.
Beyond the statement that admissibility is governed by the discretion of the trial judge, evidence should be admitted if it is relevent and apropo to the matter at hand, admissibiliity limited by the potential for prejudice or confusion.
