Relating to: admissibility of expert witness testimony.

SB 459 clarifies the standard courts must use to admit expert witness testimony in legal cases. It requires judges to determine, before testimony is presented, that it is "more likely than not" based on sufficient facts, reliable methods, and properly applied to the case details. This change directly affects courts, lawyers, and expert witnesses in civil and criminal trials by strengthening the judge's role in reviewing testimony quality. The bill does not create new laws but refines existing rules for evaluating expert evidence, applying to cases filed after its effective date.
