Attorneys may serve as expert witnesses in discrimination cases when their qualifications and proposed opinions satisfy Rule 702. This article explains the limits on legal conclusions, ultimate-issue testimony, subject-specific qualifications, and how the Koch Foods dispute illustrates the distinction between permissible expert analysis and improper legal advocacy.
An attorney may serve as an expert witness when qualified to address the proposed subject and when the testimony meets the applicable admissibility requirements. In federal proceedings governed by the Federal Rules of Evidence, those requirements include Rule 702.
Legal experience does not, by itself, permit an attorney expert to offer impermissible legal conclusions or tell the jury how the case should be decided.
That distinction was central to a 2022 ruling from the United States District Court for the Southern District of Mississippi. The case involved allegations of racial discrimination against a Black poultry grower. The court excluded the attorney's testimony because some opinions amounted to legal conclusions and others exceeded his demonstrated expertise.
This guide explains how Rule 702 applies to attorney expert witnesses, the difference between factual opinions and impermissible legal conclusions, and what the Koch Foods dispute illustrates about qualifications and the proper scope of expert testimony.
The litigation involved Carlton Sanders, a Black poultry grower who had contracted with Koch Foods entities to raise broiler chickens. Sanders alleged that Koch refused to deliver additional flocks unless he made expensive upgrades to his chicken houses that white growers were not required to make. His Chapter 7 bankruptcy trustee, Stephen H. Smith, pursued claims including racial discrimination under 42 U.S.C. § 1981 and breach of contract.
Section 1981 protects, among other rights, the equal right to make and enforce contracts without racial discrimination. The statute defines making and enforcing contracts to include their performance, modification, termination, and the enjoyment of contractual benefits and conditions.
The trustee designated attorney Robert Gibbs, who had more than 41 years of legal experience, to provide opinions concerning Sanders's contractual relationship with Koch.
The dispute over Gibbs's testimony did not decide whether racial discrimination actually occurred. In a separate order issued on June 2, 2022, the court denied Koch's motion for summary judgment on the Section 1981 and breach-of-contract claims. The expert ruling addressed whether Gibbs could present his proposed opinions to the factfinder.
In federal proceedings governed by the Federal Rules of Evidence, Rule 702 governs the admissibility of expert testimony. The rule was amended effective December 1, 2023, after the Koch Foods ruling.
Under the current rule, a qualified expert may testify if the proponent demonstrates to the court that it is more likely than not that:
The 2023 amendment clarified and emphasized that the proponent must show the court, under the more-likely-than-not standard, that Rule 702's admissibility requirements are satisfied. An attorney's professional experience may provide specialized knowledge, but the attorney must still be qualified to address the particular subject of the proposed opinion.

An attorney's professional experience may provide specialized knowledge, but the attorney must still be qualified to address the particular subject of the proposed opinion.
Federal Rule of Evidence 704(a) provides that an opinion is not automatically objectionable because it embraces an ultimate issue. The opinion must still satisfy Rule 702 and other applicable evidentiary requirements.
In the Fifth Circuit, a lawyer serving as an expert is not categorically barred from testimony that touches on legal matters when those matters involve factual questions, such as a professional standard of care. However, an expert may not instruct the factfinder on governing law, render an impermissible legal conclusion, or simply tell the factfinder how to decide the case. Testimony about professional practices or standards may assist the factfinder when the subject falls within the attorney's demonstrated expertise, while testimony that states what the law requires, declares that a party violated the law, or determines entitlement to a legal remedy may be excluded.
The precise boundary depends on the jurisdiction, claims, proposed opinion, and expert's qualifications.
Gibbs proposed to testify that Koch had treated Sanders less favorably because of race and that Koch's conduct was consistent with racial discrimination under Section 1981. He also addressed the relief Sanders could recover and whether punitive damages should be considered.
Koch argued that these opinions crossed the line from specialized assistance into legal conclusions.
The trustee responded that Gibbs could provide historical and practical context concerning issues facing the jury and relied in part on the United States Court of Appeals for the Fifth Circuit's decision in Waco International, Inc. v. KHK Scaffolding Houston Inc.
In Waco International, the Fifth Circuit explained that being a lawyer does not automatically disqualify someone from serving as an expert. The attorney there could discuss issues a reasonable attorney would typically investigate before seeking an ex parte seizure order because the testimony concerned a factual question about professional practice.
Judge Daniel P. Jordan III concluded that Gibbs's opinions were different. In the court's view, his Section 1981 opinions either told the jury how to decide the discrimination issue or explained the legal consequences of the claim.
The court found those opinions impermissible and separately considered whether Gibbs could provide historical context.
The trustee sought to use Gibbs to provide historical context concerning Black farmers in the United States. Although Gibbs had more than 41 years of legal experience, the court noted that he had no experience with poultry growing and had never worked as a historian.
Gibbs had reviewed material about discrimination against Black farmers, but the court concluded that the trustee had not shown he possessed the specialized expertise needed to provide historical analysis rather than repeat information from sources outside his expertise.
The court ultimately granted Koch's motion to exclude Gibbs's expert testimony.
Start by identifying the specific factual or professional issue the expert will address. Legal experience may support opinions about professional practice within an attorney's expertise, but it may provide little basis for opinions in an unrelated historical, scientific, financial, or industry field.
The expert report should distinguish specialized analysis from legal advocacy. Opinions are more vulnerable to exclusion when they state that a party violated a statute, is entitled to a remedy, or should prevail on a legal issue.
Each opinion should also have a clear basis. Under Rule 702, the proponent must demonstrate that the expert is qualified for the subject and that the testimony satisfies the rule's other admissibility requirements.
Can an attorney serve as an expert witness in federal court?
Yes. An attorney may qualify as an expert through relevant knowledge, skill, experience, training, or education, but the proposed testimony must satisfy Rule 702 and remain within the attorney's demonstrated expertise.
Can an attorney expert explain the law to a jury?
Generally, the judge instructs the jury on governing law. Depending on the jurisdiction and the purpose of the testimony, an attorney expert may sometimes address legal matters connected to a relevant factual issue or professional standard, but testimony that substitutes for the court's legal instructions or tells the jury how to rule may be excluded.
Can an expert testify about an ultimate issue?
Federal Rule of Evidence 704(a) provides that an opinion is not automatically objectionable merely because it embraces an ultimate issue. The opinion must still be otherwise admissible, and the rule does not automatically permit legal conclusions.
Does being an experienced lawyer qualify someone to testify about discrimination?
Not necessarily. Qualification depends on the specific opinion. Legal experience may support some professional or factual opinions, but an attorney must still possess specialized knowledge relevant to the particular subject the expert is asked to address.
Did the court in the Koch Foods case find that racial discrimination did not occur?
No. The June 2, 2022 expert ruling addressed the admissibility of particular expert testimony. In a separate order that day, the court denied summary judgment on the racial discrimination and breach-of-contract claims.
