In the recent decision of JOLLEY v. McCLAIN, Oklahoma Supreme Court 2025, the Oklahoma Supreme Court addressed the scope of permissible discovery into the financial records of a Tax Expert Witness in condemnation proceedings. The case provides critical guidance on the intersection of expert witness bias, discovery rights, and the statutory limits imposed by state law.
Background and Parties
The dispute arose from a condemnation action initiated by the Oklahoma Department of Transportation (ODOT) to acquire a strip of land owned by Christopher Charles Jolley. After negotiations failed, ODOT filed suit and, pursuant to Oklahoma law, three disinterested freeholders were appointed as commissioners to appraise the property. The commissioners valued the property at $15,310. Jolley, dissatisfied with the valuation, demanded a jury trial. ODOT identified Robert Grace as its expert appraiser for the upcoming proceedings.
Role and Methods of the Tax Expert Witness
Robert Grace, serving as ODOT’s expert appraiser, was tasked with providing an opinion on the value of the condemned property. As a Tax Expert Witness, Grace’s expertise in property valuation and tax implications was central to ODOT’s case. Jolley, seeking to challenge Grace’s credibility and potential bias, issued a subpoena duces tecum requesting three years of Grace’s financial records, including IRS Forms 1099 related to any work performed in Oklahoma condemnation actions and for any government client.
Discovery Dispute and Trial Court Ruling
ODOT moved to quash the subpoena, arguing that the request exceeded the permissible scope of discovery under the Oklahoma Discovery Code. Jolley countered that the financial records were relevant to establish bias, a critical factor in assessing the credibility of a paid expert witness. The trial court sided with ODOT, granting the motion to quash the subpoena.
Supreme Court Analysis: Daubert and Reliability Considerations
On appeal, the Oklahoma Supreme Court analyzed whether a subpoena duces tecum is an appropriate mechanism for obtaining an expert witness’s financial records. The Court emphasized that the Oklahoma Discovery Code provides specific methods for discovering information relevant to expert witness bias, and that a subpoena duces tecum is not among them. The Court reasoned that while bias is always relevant to credibility, the legislature intended to limit the means by which financial information could be obtained from expert witnesses.
The Court’s analysis reflects a broader concern with the reliability and fairness of expert testimony. By restricting the discovery of financial records to the methods expressly authorized by statute, the Court sought to balance the need for transparency regarding potential bias with the protection of expert witnesses from overly broad or burdensome discovery requests.
Impact of the Tax Expert Witness Testimony on the Outcome
The Supreme Court’s decision did not directly address the admissibility or reliability of Grace’s expert testimony under Daubert or similar standards. Instead, it focused on the procedural safeguards governing discovery. By upholding the trial court’s order quashing the subpoena, the Court reinforced the principle that discovery into an expert’s financial dealings must adhere strictly to the statutory framework. This ruling limits the ability of parties to conduct fishing expeditions into the financial affairs of opposing expert witnesses, thereby shaping the practical boundaries of expert witness cross-examination and impeachment.
Conclusion
JOLLEY v. McCLAIN, Oklahoma Supreme Court 2025 stands as a significant precedent on the discoverability of financial records from a Tax Expert Witness. The decision clarifies that, in Oklahoma, parties seeking to probe an expert’s potential bias must do so within the confines of the Discovery Code, and may not resort to subpoenas duces tecum for broad financial disclosures. This ruling provides essential guidance for litigators and expert witnesses alike, reinforcing the procedural protections surrounding expert testimony in condemnation and other civil proceedings.
