The bill amends the introductory paragraph of Code of Evidence Article 702(A) and (4) concerning expert testimony in Louisiana. It establishes that a qualified expert may provide testimony if the proponent demonstrates to the court that it is more likely than not that the expert's opinion reflects a reliable application of the principles and methods to the facts of the case. This change emphasizes the burden of proof required for expert testimony.

Additionally, the bill modifies the language regarding the reliability of expert opinions by replacing the phrase "expert has reliably applied" with "expert's opinion reflects a reliable application." This amendment aligns Louisiana's legal language with the 2023 amendments to Rule 702 of the Federal Rules of Evidence, ensuring consistency in the standards for expert testimony.
