Provides relative to expert witness fees

House Bill 437 makes two primary changes to Louisiana's expert witness rules by amending the Code of Civil Procedure and adding provisions to the Code of Evidence. First, it enacts Code of Evidence Article 702(C), which establishes that a witness with a pecuniary interest in the outcome of a case shall not be qualified as an expert witness. Second, it enacts Code of Evidence Article 702(D), which defines pecuniary interest to mean any compensation from or relating to an award of damages, engagement to provide goods or services connected to an award, or any financial benefit from or relating to the testimony beyond the compensation disclosed for the study and testimony itself, with an explicit exception for expert witnesses who are or have been employees of a party. Additionally, the bill amends Code of Civil Procedure Article 1425(B) to require disclosure in expert witness reports of past cases in which the witness held a pecuniary interest in the outcome, including the name of the case and the nature and value of the compensation received.

The practical effect of this legislation is to disqualify expert witnesses from testifying in cases where they have a financial stake beyond their standard expert fees, while simultaneously requiring transparency about their financial interests in prior litigation. Any attorney in Louisiana who retains an expert witness must now ensure that the expert has no disqualifying pecuniary interest and, when ordered by the court or by party agreement, must disclose in the expert's report all past cases where the expert held such a financial interest. This change will substantially impact expert witness selection and retention practices across all civil litigation in the state, as attorneys will need to vet experts more carefully for conflicting financial interests and cannot rely on experts who have compensation arrangements tied to case outcomes or awards.

This legislation operates within Louisiana's existing framework governing expert witness testimony qualification and discovery requirements. Code of Evidence Article 702 has long governed the qualifications necessary for expert testimony, and Code of Civil Procedure Article 1425 has established the pretrial disclosure requirements for expert witnesses. By adding subsections C and D to Article 702, the bill elevates the regulation of expert witness financial conflicts to the level of substantive evidence rules, making pecuniary interest a disqualifying factor at the threshold stage of expert qualification. The amendment to Article 1425(B) expands the list of optional or court-ordered disclosures that may be included in expert reports, alongside existing requirements regarding qualifications, exhibits, and compensation. These changes operate in tandem with Louisiana's broader discovery rules and the obligation of candor owed to courts, addressing concerns about expert witness bias and financial motivation in civil litigation.
