The bill amends Section 2702 of Title 12 of the Oklahoma Statutes, which pertains to the testimony of expert witnesses in civil procedures. It introduces a requirement for the proponent of expert testimony to demonstrate to the court that it is more likely than not that the testimony meets certain criteria. These criteria include 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 modifies the language regarding the expert's application of principles and methods, replacing the phrase "witness has applied" with "expert's opinion reflects a reliable application." The bill is set to take effect on November 1, 2025.
