This bill amends Section 2702 of Title 12 of the Oklahoma Statutes, which pertains to the testimony of expert witnesses in civil procedures. The proposed changes require that the proponent of expert testimony must demonstrate to the court that it is more likely than not that the testimony is based on sufficient facts or data, is the product of reliable principles and methods, and that the expert's opinion reflects a reliable application of these principles and methods to the facts of the case.

Additionally, the bill removes the previous requirement that the witness has applied reliable principles and methods to the facts of the case, replacing it with a focus on the reliability of the expert's opinion. This legislation aims to enhance the standards for admitting expert testimony in court, ensuring that such testimony is grounded in reliable and demonstrable methods. The act is set to take effect on November 1, 2025.
