  • Pensions Expert Witness’ Testimony on Benefits under ERISA’s Accrual Rules Admitted

    Pensions Expert Witness’ Testimony on Benefits under ERISA’s Accrual Rules Admitted

    Plaintiffs bring this suit under the Employee Retirement Income Security Act (ERISA).

    ERISA’s central object is to “protect employees’ justified expectations of receiving the benefits their employers promise them.” This case centers on the Coastal Transition Benefit, a benefit formula that originated in the Coastal Plan and that, through a series of corporate transactions, now appears in the Plan. Plaintiffs alleged the Coastal Transition Benefit formula improperly accrued benefits over participants’ entire careers rather than over their first 30 years of service in violation of various provisions of ERISA.

    As the Court knows, two of Plaintiffs’ claims—Claims I and VI—center on Plaintiffs’ contentions that the Coastal Transition Benefit formula is impermissibly backloaded and that the Plan’s actuarial factors used to reduce benefits for commencement before normal retirement date are unreasonable.

    Defendants sought to exclude the testimony of Plaintiffs’ expert Michael L. Libman as unreliable under Federal Rule of Evidence 702. Plaintiffs offered Libman as an expert on benefits under ERISA’s accrual rules and “actuarial equivalent” reductions.

    Pensions Expert Witness

    Michael Libman has been a pension actuary for over forty years. In that time, he has testified as an expert on pension issues in many cases.

    Discussion by the Court

    Libman’s expert reports supported Claims I and VI and his testimony is based upon a close read of statutory rules, Treasury Regulations, applicable legal precedent and authority, the Plan document, and relevant documentation provided by Defendants.

    Based on his read of the Plan provisions, Libman’s report set forth actuarial calculations to assess whether the Plan complies with ERISA’s anti-backloading and actuarial equivalence provisions.

    The Court held that while some of Libman’s interpretations of the Plan are perhaps open to question, there is no issue with the reliability of his testimony in general.

    Held

    The Court denied the Defendants’ motion to exclude the testimony of Michael Libman.

    Key Takeaway:

    After reviewing the parties’ filings and Libman’s testimony, the Court finds that Plaintiffs have shown, by a preponderance of the evidence, that Libman’s testimony is reliable. In so finding, the Court notes that the Daubert inquiry does not require district courts to assess whether an expert’s testimony is correct; courts need only determine whether the testimony is reliable.

  • Toxicology Expert Witness’ Testimony Regarding the Plaintiff’s Blood Alcohol Content Admitted

    Toxicology Expert Witness’ Testimony Regarding the Plaintiff’s Blood Alcohol Content Admitted

    Plaintiff Sandra Corbin filed a civil rights action against the Defendants Bill Prummell, Jr., as sheriff of the Charlotte County, David Gensimore, and Aaron Williams as a result of Corbin sustaining a fractured leg, and a litany of related and subsequent damages due to excessive force employed by Williams.

    On November 29, 2019, at around 9:45 PM, Plaintiffs, John Corbin and Sandra Corbin were stopped by Charlote County Deputies Michael Davidson and Aaron Williams. Plaintiffs were stopped upon leaving a restaurant/bar where both Mr. Corbin and Mrs. Corbin consumed a couple of beers.

    During the traffic stop of Plaintiffs, Mr. Corbin was removed from the vehicle by Deputy Davidson to perform a field sobriety test (FST), while Mrs. Corbin remained in the vehicle. Mrs. Corbin attempted to go around Deputy Williams to observe what was happening with Mr. Corbin; and at that moment Deputy Williams deployed a “leg sweep” or “leg whip” with such force it took Mrs. Corbin to the ground; and fractured her leg.

    Corbin filed a motion to exclude the testimony of Defendants’ proposed expert, Teri L. Stockham, a forensic toxicologist who opined that Sandra Corbin was intoxicated such that her normal faculties were impaired at the time of this incident. This opinion is based on scientific evidence of the hospital serum ethanol result of 206 mg/dL almost two hours after the incident.

    Toxicology Expert Witness

    Teri Stockham holds three degrees: A Bachelor of Science in chemistry, a Master of Science in forensic science and forensic toxicology, and a Doctor of Philosophy in pharmacology and toxicology. She has thirty-five years of toxicology experience, including a stint as Chief Toxicologist at Broward County Medical Examiner’s office.

    Get the full story on challenges to Teri Stockham’s expert opinions and testimony with an in-depth Challenge Study. 

    Discussion by the Court

    Qualifications

    The Corbins argued that Stockham was not qualified to testify on Sandra Corbin’s state of mind, behavior, etc., that her opinion was not based on reliable scientific or technical testing, and that the testimony will not assist the trier of fact.

    Plaintiffs argued that Stockham, as a toxicologist, is not qualified to opine on how Sandra Corbin comported herself during the night in question since Stockham “never met with Sandra Corbin, nor discussed the events of November 29, 2019.”

    The Court held that Stockham is not testifying that she personally knows Corbin behaved a certain way during the night in question. She is offering testimony regarding Corbin’s blood alcohol content (BAC) and the “signs and symptoms” she would “expect” with that BAC.

    Hence, the Court held that Stockham is qualified as an expert to interpret BAC “not because of her familiarity with Sandra Corbin, but because
    of her familiarity with the analysis she was tasked with performing.”

    Reliability

    Plaintiffs argued that Stockham’s testimony was not reliable for many reasons, including because it relied not on statistical data but on Sandra Corbin’s blood alcohol level taken two hours after the event and did not consider pertinent deposition testimony or Sandra Corbin’s alcohol tolerance level.

    Stockham’s opinion is based “on scientific evidence of the hospital serum ethanol result of 206 mg/dL” which she converted to BAC. The Court held her opinion is reliable because it is generally accepted that alcohol content levels give reliable estimates of a person’s intoxication, and “[a]nalysis of blood samples gives the most accurate results.”

    Assistance to the trier of fact

    The third requirement asks “whether that reasoning or methodology properly can be applied to the facts in issue.”

    Plaintiffs argued that “an opinion or determination of intoxication” is unhelpful here as Florida’s driving under the influence statute is irrelevant and “there is no requisite or comparable BAC level under” Florida’s disorderly intoxication statute.

    The Court held that Stockham’s opinions regarding Corbin’s BAC and the effects expected of a person with that level of BAC “are helpful for the factfinder because, although the general effects of alcohol consumption are commonly known, the methodology for determining an individual’s BAC and an opinion on the associated physiological manifestations of a specific BAC level are beyond the understanding and experience of the average lay citizen and goes to the ultimate finding” of whether Corbin was intoxicated.

    Held

    The Court denied the Plaintiffs’ motion to exclude the testimony of Teri L. Stockham.

    Key Takeaways:

    None of Plaintiffs’ arguments to exclude Stockham’s testimony are persuasive. Stockham is qualified, her outlined opinion above is reliable, helpful, relevant, and its probative value does not outweigh the danger of unfair prejudice, confusion of the issues, or misleading of the jury.

    • Even if accepted as true that, for example, certain deposition testimony was omitted, misstated, or contradicted and that pertinent information such as Corbin’s age, fatigue, or food consumption was overlooked, any such shortcomings would go to the weight of the evidence, not to admissibility.
    • Plaintiffs’ argument misconstrued Stockham’s offered testimony and applied a higher bar for the qualification of an expert than precedent required.

  • Forensic Expert Witness’ Testimony About Use of Deadly Force Admitted

    Forensic Expert Witness’ Testimony About Use of Deadly Force Admitted

    In November 2020, Defendant and another deputy were attempting to serve felony arrest warrants on Jacob Settle and Sophronia Whitehead at their residence. When the deputies arrived, Settle was in the driver’s seat of a truck. Settle did not comply with the deputies’ commands to exit the truck, and he started the truck and took it out of park. Then, according to Defendant, the truck backed up before starting to move forward towards him. Defendant fired two shots into the truck, killing Settle.

    In November 2022, the personal representative of Settle’s estate (Plaintiff) filed this suit against Defendant, the other deputy at the scene, and the Escambia County Sheriff.

    The propriety of Defendant’s use of deadly force against Settle will likely depend on whether he reasonably believed that he was at risk of being struck by the truck when he fired the shots into the truck. That, in turn, may depend on whether the truck was moving and where Defendant was in relation to the truck’s actual or potential path of travel when he fired.

    To support her position that Defendant was not at risk of being struck by the truck when he fired the shots that killed Settle, Plaintiff presented the expert testimony of a “forensic services technician,” Kelly Timms. Defendant does not challenge Timms’ qualifications, but he contends that several of her opinions should be excluded because they are beyond her expertise, irrelevant, or based on conjecture or speculation.

    Forensic Expert Witness

    Kelly Timms worked as a crime scene technician in Maryland for 10 years. Timms attended the University of Findlay, where she completed her Bachelor of Science degree in Biology. Timms continued to Stevenson University and completed a Master of Science degree in Forensic Science. During the last year of the Master Program, Timms began a yearlong internship and was hired as a full-time crime scene technician in the fall of 2013. Timms obtained training for shooting reconstruction, bloodstain pattern analysis, and crash investigation. She has investigated cases involving homicides, shooting incidents, pedestrian crashes, and major drug investigations working with local, state, and federal agencies. Timms has prepared expert reports on bloodstain pattern analysis and shooting reconstruction. Kelly is a Certified Senior Crime Scene Analyst through the IAI.

    Get the full story on challenges to Kelly Timms’ expert opinions and testimony with an in-depth Challenge Study. 

    Discussion by the Court

    Timms testified beyond the scope of her expertise

    The first challenged opinion relates to the trajectory of one of the bullets that struck Settle. Defendant argued that this opinion is beyond the scope of Timms’ expertise because it is based on the autopsy report, and she is not a medical professional. However, the Court failed to see how medical expertise was necessary to evaluate the trajectory of a projectile or why Timms cannot rely on the information presented in the autopsy report to formulate an opinion about Defendant’s location when the shots were fired based on the trajectories of the bullets. 

    The third set of challenged opinions relate to the positioning of Settle’s left hand and body when he was struck by what Timms described as the second shot. Defendant contended that these opinions are beyond the scope of Timms’ expertise because she is not a medical professional and that they are speculative because Timms admitted in her deposition that she could not say with any certainty where Settle was positioned in the truck or which injuries related to which shot. However, the Court held that “absolute certainty is not required” and “the weaknesses in the underpinnings of the expert’s opinion go to its weight rather than its admissibility.”

    Timms’ opinion lacks relevance

    The second set of challenged opinions relate to Defendant’s location when he shot into the truck and are apparently intended to refute any claim that Defendant was directly in front of the truck when he fired. Defendant contended that this opinion is irrelevant (and, thus, unhelpful) because he never claimed that he was directly in front of the truck when he fired. However, Defendant’s location at the time he fired is a hotly contested fact, and as Plaintiff argues, Defendant’s testimony about this issue in his deposition is susceptible to multiple interpretations. Thus, Timms’ opinion that Defendant was not directly in front of the truck when he fired is relevant and admissible.

    Timms’ opinions are based on speculation and conjecture

    The fourth challenged opinion relates to Defendant’s location when he shot into the truck and is based on the location of a spent cartridge found at the scene. Defendant contended that this opinion is based on speculation and conjecture because the location of the cartridge is not indicative of Defendant’s location since the yard was full of debris that the cartridge could have bounced off. However, Defendant has not challenged Timms’ qualifications as a crime scene investigator, and as Plaintiff argued, she sufficiently explained how she reached that opinion based on her experience.

    The fifth challenged opinion relates to an “observation” made by Timms in her report about the location of an injury on Defendant’s leg in relation to the damage to his pants. However, when asked whether she was offering an opinion on this matter or if it was just an observation, Timms stated in her deposition that this was “just an observation.” Accordingly, there is no opinion related to that observation for the Court to exclude.

    Held

    The Court denied Defendants’ Daubert motion to exclude the testimony of Kelly Timms.

    Key Takeaway:

    Defendant did not challenge Timms’ qualifications, but he contended that several of her opinions should be excluded because they are beyond her expertise, irrelevant, or based on conjecture or speculation. 

    The Court held that the issues raised by Defendant go to the weight of Timms’ opinions, not their admissibility.

  • Drug Enforcement Expert Witness Allowed To Testify Despite Not Being A Pharmacist

    Drug Enforcement Expert Witness Allowed To Testify Despite Not Being A Pharmacist

    Manes is a pharmacy that has served the Van Buren, Arkansas community for nearly 40 years. AmerisourceBergen is a wholesale distributor of pharmaceutical products, including controlled substances. This dispute arises from AmerisourceBergen’s decision to restrict its sale of controlled substances to Manes. Manes sued AmerisourceBergen for breach of contract, tortious interference with Manes’ business expectancies, defamation, and compelled self-defamation.

    Both parties sought to exclude some of their opponent’s experts. Manes sought to exclude the testimony of James Place and Deborah Komoroski. AmerisourceBergen sought to exclude the testimony of Jack Teitelman

    Drug Enforcement Expert Witnesses

    James Place has 27 years of experience working for the United States Drug Enforcement Administration and nearly ten years of doing compliance work in the private sector.

    Get the full story on challenges to James Place’s expert opinions and testimony with an in-depth Challenge Study. 

    Deborah Komorski works for Cencora, Inc., which is AmerisourceBergen’s parent company. She has eight years’ experience as a pharmacist, twenty-five years’ experience as a Drug Control Agent for the State of Connecticut, and thirteen years’ experience doing compliance and diversion control work for private companies. 

    Fortify your strategy by reviewing a Challenge Study detailing grounds for excluding Deborah Komorski’s expert testimony. 

    Jack Teitelmean worked for the DEA as a special agent for 13 years, and he has worked in other law enforcement capacities for an additional 13 years. For the last seven years, he has worked for a private company which he describes as “a leading Veterinary Industry provider of DEA-compliance and controlled-substance anti-diversion solutions.” 

    Want to know more about the challenges Jack Teitelmean has faced? Get the full details with our Challenge Study report. 

    Discussion by the Court

    James Place

    Manes argued that the Court should exclude Place’s opinions because he was not a pharmacist and his expert report contained opinions about “the practice of pharmacy and how a pharmacist fulfills his/her corresponding responsibility.” Additionally, Manes argued that Place should be excluded under Arkansas law because he could not judge whether a medical professional had deviated from the accepted standard of care.

    The Court held that the Arkansas statute titled “Plaintiff’s burden of proof” Manes relied on did not apply to this case because Manes is the Plaintiff here and this is not an action for negligence. Also, the statute’s definition of medical care provider does not include a drug distributor like AmerisourceBergen. Moreover, Manes has alleged injuries arising out of AmerisourceBergen’s decision to stop selling it controlled substances instead of a medical injury.

    Place’s opinions do not discuss the exercise of pharmacological judgment

    The Court found that Place’s testimony discussed the steps a distributor or government agency might take when investigating possible diversion. Place’s opinions did not question the drugs Manes’ pharmacists dispensed; his opinions questioned the steps the pharmacists took to investigate questionable prescriptions based on red flags (such as commonly diverted substances) before filling the prescriptions. This opinion fell within his decades of experience with investigations and compliance in the public and private sectors.

    Moreover, Manes argued the following opinion is impermissible: “AmerisourceBergen was justified in questioning Plaintiff’s ability to satisfy its corresponding responsibility for the proper dispensing of controlled substances.” The Court held that Place’s opinion is made from the perspective of an outside investigator, not that of a pharmacist challenging Manes’ pharmacist’s pharmacological judgment.

    Some of Manes’ objections are simply disputes over the factual basis for Place’s opinions

    Manes took issue with paragraph 39 of Place’s report. That paragraph read, in part, “[p]roper controls can be accomplished by following common sense, sound professional practice, and proper dispensing procedures.”

    This paragraph is a direct quote from the DEA’s Pharmacist’s Manual. Manes argued that this is an example of where Place “opines as to what pharmacies and pharmacists should or should not do.” The Court held that the paragraph is an example of what the DEA says what a pharmacist should or should not do. In other words, Manes’ argument missed the mark because it challenged the factual basis for Place’s opinions.

    Deborah Komoroski

    Manes next asked the Court to exclude Deborah Komorski because she is testifying on matters outside of her experience. Manes made the same argument as above about Arkansas’s standard of care for pharmacists, which the Court rejected for the same reasons stated above: the statute did not apply to this case.

    Plaintiff objected to Komoroski’s opinions which discussed AmerisourceBergen’s processes when investigating whether a pharmacist carries out their corresponding responsibility. The Court held that these opinions all fall within her decades-long experience as both a pharmacist and diversion control agent.

    Manes argued that not only did Komorski fail to consider all the facts but Komoroski cannot testify as to the applicable standard of care because she never practiced pharmacy in Arkansas. The Court did not find any of these arguments convincing because Komoroski’s opinions did not discuss the standard of care.

    Jack Teitelman

    AmerisourceBergen argued that because Teitelman failed to review a multitude of key sources of information, his testimony should be excluded because it is “so fundamentally unsupported that it can offer no assistance to the jury.” The Court held that while Teitelman’s report may have more thoroughly listed the documents he relied on, that he might base his opinion on different facts than Place does not render his opinion inadmissible.

    AmerisourceBergen argued Teitelman is unaware of the steps in its investigation. However, the Court found that reviewing Teitelman’s report in its entirety reveals that he is aware of various steps AmerisourceBergen took as part of its investigation.

    Teitelman’s report attempts to explain how Ruan V. United Statess, 497 U.S. 450 (2022) applies to the way that AmerisourceBergen and the DEA should evaluate a pharmacist’s corresponding responsibility. The Court held that Teitelman’s testimony about Ruan impermissibly ventured into testimony about legal matters because he applied the Ruan case out of its criminal context.

    The Court did not agree with AmerisourceBergen that Teitelman’s opinions about AmerisourceBergen’s policies were unreliable because they were purely speculative. AmerisourceBergen primarily argued that because Mr. Teitelman did not have personal knowledge of how AmerisourceBergen’s policies had changed over time, his opinions on the topic should be excluded. However, Teitelman based his opinion in part on his previous work with pharmacies that had a relationship with AmerisourceBergen.

    Held

    The Court denied Manes’ motion to exclude the testimony of James Place and Deborah Komoroski but granted in part and denied in part AmerisourceBergen ‘s motion to exclude the testimony of Jack Teitelman.

    Key Takeaways:

    • Place’s opinions all fall within his area of expertise and Arkansas’s statute about the standard of care does not apply in this case. Manes is free to challenge the factual basis of Place’s opinions on cross-examination, but Manes has not identified any reason Place’s testimony is inadmissible.
    • As per Rule 703, Teitelman can base his opinion on facts or data he has been made aware of or personally observed.

  • Construction Expert Witness’ Deposition Testimony deemed “Incomplete and Inconclusive”

    Construction Expert Witness’ Deposition Testimony deemed “Incomplete and Inconclusive”

    This action stems from a trip and fall incident that occurred on July 19, 2019, while Plaintiff, Carolyn Simmons was walking and tripped along a dangerous and defective sidewalk located in front of Rite Aid in Ridgeland, South Carolina. The Defendant, Rite Aid of South Carolina, Inc., Walgreens, and Sitaras and Tzioros Properties, Inc., (hereafter referred to as “Defendant”), is a national drug store chain located in Ridgeland, State of South Carolina.

    Defendant Sitaras and Tzioros Properties, Inc.’s (hereafter “Defendant”) filed a motion to exclude the testimony of Plaintiff’s expert Gerald Neal.

    Construction Expert Witness

    Gerald Neal is licensed general contractor with eighteen years of experience in project management and facilities engineering. Moreover, he has extensive experience constructing and renovating homes, offices, apartments, restaurants, and churches.

    Want to know more about the challenges Gerald Neal has faced? Get the full details with our Challenge Study report. 

    Discussion by the Court

    While the case was still pending in state court, Plaintiff identified Neal as an expert witness and indicated, in response to Defendants’ interrogatories, that Neal was “compiling” documents and would forward these upon receipt.

    After the case was removed to United States District Court, the Plaintiff’s expert report was due by March 26, 2024. According to Defendant’s motion, no expert report meeting Rule 26(a)(2)(B) requirements had been produced by Plaintiff under the Court’s scheduling order.

    Also, Neal was deposed while the case was still pending in state court. Besides, he stated in his deposition that he lacked certain important information that was necessary to finalize his opinions. Specifically, Neal testified that he needed the date of the building’s certificate of occupancy because that would determine the specific building code that was applicable to this incident.

    Subsequently, Defendant filed its motion to exclude more than two months after the deadline in the scheduling order for the production of expert reports. Defendant’s assertions that it has never been provided an expert report from Neal and that his deposition testimony was “incomplete and inconclusive” have gone unchallenged by Plaintiff since no response to the motion to exclude was filed.

    Ultimately, the Court found that no good cause or substantial justification has been shown for the failure to timely produce an expert report and the failure to comply has not been shown to be harmless.

    Held

    To conclude, the Court granted Defendant’s motion to exclude the testimony of Gerald Neal as an expert witness at trial.

    Key Takeaway:

    To conclude, the Court found that no good cause or substantial justification had been shown for the failure to timely produce an expert report. Furthermore, the failure to comply has not been shown to be harmless.

    In short, when considering a motion to exclude an expert witness for failure to produce a required expert report, the Court must address two applicable rules. First, Fed. R. Civ. P. 16(b)(4) provides that a scheduling order may be modified only “for good cause and with the judge’s consent.” Second, even where a timely expert report has not been produced, an expert will not be excluded so long as the failure to timely produce the report is “substantially justified or is harmless,” as per Fed. R. Civ. P. 37(c)(1).

  • Demography Expert Witness Allowed to Analyse Various Maps At Issue

    Demography Expert Witness Allowed to Analyse Various Maps At Issue

    This is a vote dilution case where Plaintiffs challenge the configuration of Mississippi’s State Supreme Court districts, which, despite population changes and the passage of four Censuses, have gone unchanged since 1987. The result of this districting scheme is an unequal playing field for Black voters, such that Mississippi’s nine-member Supreme Court has never had more than a single Black Justice at a time, despite the State’s voting-age population being approximately 36% Black.

    The Plaintiffs filed a motion to partially exclude, wherein they requested that the Court exclude certain portions of the proposed testimony of David Swanson, one of the Defendants’ experts. More particularly, the Plaintiffs requested that Swanson be precluded from testifying regarding electoral map drawing and ecological inference analysis.

    Demography Expert Witness

    David A. Swanson is: (1) Edward A. Dickson Emeritus Professor of Sociology, University of California Riverside; (2) Research Associate, Population Research Center, Portland State University; (3) Faculty Affiliate, Center for Studies in Demography and Ecology, University of Washington; and (4) Research Fellow, Social Science Research Center, Mississippi State University. Swanson served as a member of the U. S. Census Bureau’s Scientific Advisory Committee for six years (2004-10) and chaired the committee for two (2009-2010).

    His B.Sc. is from Western Washington State College (now Western Washington University), and his Ph.D. and M.A. are from the University of Hawai’i. He also holds a Graduate Diploma in Social Sciences from the University of Stockholm.

    Get the full story on challenges to David Swanson’s expert opinions and testimony with an in-depth Challenge Study.

    Discussion by the Court

    Swanson Is An Expert In Understanding Maps

    The Plaintiffs have retained William Cooper as an expert. Cooper has prepared a report that contains four proposed new redistricting plans (two illustrative plans and two “least change” plans). According to Cooper, the proposed plans would create a majority-BVAP District. Swanson, who the Defendants retained as an expert in demography, prepared two reports—the first of which expends considerable effort and time addressing the illustrative plans contained in Cooper’s report.

    The Plaintiffs argued that Swanson has no experience drawing electoral
    maps, and no specialized knowledge with respect to electoral maps. The Court agreed with the Defendants’ position that Swanson “has never claimed to be an expert in drawing maps. He is, however, an expert in understanding maps. His demographic analysis of the various maps potentially at issue in this case is accurate.”

    The Court held that Swanson’s testimony should be limited to his opinions as to the maps that Cooper has drawn and his opinions pertaining to them.

    In reaching this conclusion, the Court is cognizant that the Plaintiffs have pointed to certain qualifications that Swanson lacks. Those issues appear to be ripe questions for cross-examination.

    Swanson attacked Burch’s analysis regarding the State of Mississippi as a whole

    The Plaintiffs’ second point of contention pertains to ecological inference analysis. The Plaintiffs have designated Dr. Traci Burch as an expert. Although her report and rebuttal report address multiple issues related to political behavior, barriers to voting, and political participation, of particular importance here is her utilization of a method referred to as King’s Ecological Inference analysis (“King’s EI”) in estimating voter turnout by race.

    Swanson’s surrebuttal report addressed Burch’s analysis and pointed to what he believed were flaws in that analysis. For instance, he stated that “[i]n constructing her Ecological Inference (EI) model of existing District 1, Burch erroneously included Adams County (a county in existing District 2) and erroneously excluded Bolivar County (a county in existing District 1).” Swanson’s surrebuttal report also stated that Burch’s findings in regard to King’s EI did not change his “opinion that Black Mississippians are able to participate effectively in the political process. As I showed in my initial report, Blacks voted at higher rates than Whites in District 1.” Swanson also attacked Burch’s analysis regarding the State of Mississippi as a whole because she “express[ed] an opinion about White voters relative to non-white voters not an opinion about White voters relative to Black voters.”

    The Plaintiffs contended that Swanson had no experience using the King’s EI Technique relied on by Burch and added that he is admittedly not an expert in voting behavior to which Defendants replied that Swanson has not attacked the mechanics of Burch’s King’s EI analysis but, instead, his testimony will be that Burch’s “answers are not helpful because she is asking the wrong questions.”

    The Court noted that the distinction between the proposed testimony and the underlying mechanics of King’s EI is critical but refrained from altogether precluding Swanson from testifying on this topic.

    Held

    The Court denied the Plaintiffs’ motion to partially exclude the proposed testimony of Defendants’ expert, David Swanson.

    Key Takeaway:

    • Although Swanson lacked the required expertise in electoral mapdrawing and voting behavior, the Court did not exclude his demographic analysis of the various maps potentially at issue in this case.
    • The Court did not fully preclude Swanson from identifying what he believed were flaws in Burch’s analysis.

  • Law Enforcement Expert Witness’ Supplemental Report on Deviation from Police Practices Admitted

    Law Enforcement Expert Witness’ Supplemental Report on Deviation from Police Practices Admitted

    Plaintiff Kevin Strickland filed this lawsuit against the Kansas City, Missouri, Board of Police Commissioners and five Kansas City police officers for alleged unconstitutional conduct that resulted in his wrongful conviction.

    On June 21, 2024, Plaintiff issued its police practices expert, Russell Fischer’s supplemental report. The supplemental report is 2.5 pages long, and the revisions are made based on three third-party deposition transcripts that Fischer states were not available to him at the time of his initial report dated April 5, 2024. The relevant deposition transcripts are those of Pete Edlund (deposed on April 3); Alfred Gordon (deposed on May 13); and Bridgett Gordon (deposed on May 13). Pete Edlund was a KCPD homicide detective who investigated the 1978 triple homicide. Alfred and Bridgett Gordon were both interviewed by the KCPD during the triple homicide investigation.

    Defendants moved to strike the supplemental report, arguing it contained new opinions untimely disclosed in violation of Rule 26(e).

    Law Enforcement Expert Witness

    Russell Fischer retired as the Chief of the Criminal Investigations Division specifically in charge of all investigative matters relating to homicide, robbery, sex crimes, domestic crimes and related functions task force operations.

    Get the full story on challenges to Russell Fischer’s expert opinions and testimony with an in-depth Challenge Study. 

    Discussion by the Court

    The Court held that the parties’ pretrial disclosures under Rule 26(a)(3) were not yet due, so the issue was whether the Supplemental Report contained “entirely new opinions” as Defendants alleged or rather newly discovered information that merely “completed” the initial report. To begin with, Defendants failed to provide specific examples of how the Supplemental Report provided “entirely new opinions,” and the Court found none. Both reports opined on whether officers deviated from minimally acceptable police practices during the homicide investigation. The Supplemental Report merely considered Alfred and Bridgett Gordon and Pete Edlund’s version of events in opining on the same.

    Defendants also took issue with the fact the Supplemental Report was disclosed after the discovery deadline passed and after Defendants’ deadline to depose Fischer. While the timing was not ideal, Plaintiff maintained two of the three deposition transcripts were not available until the day discovery closed, making it impossible to provide the Supplemental Report beforehand. Plaintiff also added that Defendants have never attempted to take Fischer’s deposition to date.

    The Court denied the Defendants’ motion since finding supplementation will best serve the purposes of Rule 26.

    To ensure Defendants were not disadvantaged in any way, the Court permitted Defendants to depose Fischer out of time.

    Held

    The Court denied the Defendants’ motion to strike as untimely and improper the supplemental report of Plaintiff’s expert witness, Russell Fischer.

    Key Takeaway:

    Rule 26(e)(1) provides that “a party who has made a disclosure under Rule 26(a) must supplement or correct its disclosure in a timely manner if the party learns that in some material respect the disclosure or response is incomplete or incorrect, and if the additional or corrective information has not otherwise been made known to the other parties during the discovery process or in writing.” 

    However, Rule 26(e) does not provide a vehicle for parties to merely “revise or change its disclosures,” “to bolster an expert’s opinion,” or “to present entirely new theories.”

  • Accounting Expert Witness Barred from Testifying because He Used Simple Addition to Derive Infringing Sales

    Accounting Expert Witness Barred from Testifying because He Used Simple Addition to Derive Infringing Sales

    Plaintiff, a prominent telecommunications service provider, has established the well-known marks “LIGHTSPEED” and “LIGHTSPEED VOICE” in connection with its telecommunications services. When Defendant opened a business called LIGHTSPEED CONSTRUCTION GROUP, Plaintiff alleged that the mark was nearly identical to its marks in connection with the offering of confusingly similar telecommunications services.

    Plaintiff added that such use creates a likelihood of confusion with Plaintiff’s customers.

    In this trademark infringement case, Plaintiff sought, among other things, disgorgement of Defendant’s profits during the period of alleged infringement.

    Plaintiff obtained an expert report from accountant Kevin Kwan. Defendant claimed that the report simply added two numbers together and filed a motion to exclude his testimony. 

    Accounting Expert Witness

    Kevin Kwan has over 23 years of experience providing consulting and expert witness services in various business disputes, complex commercial litigation matters, and financial investigations. Kevin’s experience includes development of complex financial models, as well as compilation, organization, and analysis of large volumes of historical data through the development of databases.

    Discussion by the Court

    Defendant did not contest Kwan’s qualifications or reliability, but argued that his testimony would not be helpful to the factfinder.

    The Court found that Kwan’s relevant testimony is limited to calculating Defendant’s sales. He also opined that “disgorgement of Defendant’s profits appear[s] to be a reasonable measure of monetary relief in this matter.” But the appropriate form of relief in this case is a legal conclusion, and expert witnesses “may not offer legal conclusions” outside of exceptional circumstances.

    Since the Court has already determined that actual damages for injuries like lost profits are inappropriate, Kwan’s support for a disgorgement remedy was—at best—an unnecessary restatement. Besides, Kwan offered that conclusion because he “did not see any particular lost profits that could be claimed” by Plaintiff.

    In trademark cases, profits subject to disgorgement are calculated as the infringing sales less the incremental costs associated with those sales. Yet Kwan “did not perform an analysis of Defendant’s incremental costs associated with generating the infringing sales.” He also admitted that he has no opinion on Defendant’s costs. Kwan’s testimony is, therefore, limited to the amount of Defendant’s sales during the alleged infringement.

    Kwan’s estimate of Defendant’s infringing sales is the sum of two numbers. The numbers originated from two documents that Defendant produced to show their sales in 2022 and 2023. Kwan added these numbers together to derive Defendant’s total infringing sales. The Court held that simple addition is within the bailiwick of the average lay person and can be presented in closing arguments. Therefore, Kwan’s testimony does not merit admission.

    Held

    The Court granted Defendant’s motion to exclude the testimony of Kevin Kwan and excluded Kwan from testifying at trial.

    Key Takeaways:

    • The appropriate form of relief in this case is a legal conclusion, and expert witnesses “may not offer legal conclusions” outside of exceptional circumstances.
    • Simple addition is within the bailiwick of the average lay person and can be presented in closing arguments. Expert testimony generally will not help the trier of fact if it “offers nothing more than what lawyers for the parties can argue in closing arguments.”

  • Neurology Expert Witness’ Testimony Excluded Because He Does Not Offer a Proper Medical Conclusion

    Neurology Expert Witness’ Testimony Excluded Because He Does Not Offer a Proper Medical Conclusion

    This is a personal injury action stemming from an accident between two tractor trailers. On November 10, 2020, while operating a truck on behalf of his employer, Robert Hibbert was rear-ended by another tractor trailer. 

    Witnesses noted that he “did not stop and was slumped over the wheel”; the EMS report indicated that Plaintiff, Hibbert did not remember what happened.

    Hibbert suffered a stroke on or about May 22, 2013 and alleged that the symptoms he exhibited after the accident are similar to those he exhibited around the time of his 2013 stroke. Plaintiff sought to have his treating physician, Dr. John E. Robinton, to testify that Plaintiff “hit his head and lost consciousness” as a result of the accident, that this impact caused a concussion, and that the concussion triggered a stroke. 

    In the “Impression” section of his report, Robinton made the following comment, which formed the basis for this motion: “Given the fact that the recent MRI revealed no evidence of an acute injury, I am hopeful that the present complaints and findings are related to a concussion.” Robinton also noted in a letter dated March 30, 2021 that, after reviewing Plaintiff’s neuropsychological assessment, “it did not appear that the report is absolute in [its] conclusion regarding etiology.” From this, Plaintiff argued, Dr. Robinton can testify regarding a possible concussion because “the issue of the concussion has not been ruled out.” 

    Defendant sought to preclude Robinton’s testimony that the November 10, 2020 accident caused any injury to Plaintiff.

    Neurology Expert Witness

    John E. Robinton is a neurologist in Montclair, New Jersey and is affiliated with multiple hospitals in the area, including Mountainside Medical Center at Hackensack Meridian Health and Saint Michael’s Medical Center. Firstly, he received his medical degree from Weill Cornell Medicine and has been in practice for more than 20 years. Moreover, Dr. John E. Robinton has expertise in treating Parkinson’s disease, neck pain and spine problems, non-Alzheimer’s dementia, among other conditions.

    Discussion by the Court

    The Court found that there is no evidence in the record indicating that Plaintiff sustained head trauma or any other kind of injury in the accident, and Robinton’s remark only expresses “hope[] that the present complaints and findings are related to a concussion.”

    Plaintiffs sought to have Robinton testify that another injury, e.g., a concussion caused by the accident, triggered Plaintiff’s condition merely because “[t]here is no etiology showing the cause of the Plaintiff’s stroke from this accident.” The Court held that the mere absence of evidence concerning etiology does not open the door to rank speculation as to what else may or may not have been the cause of the post-accident symptoms—and certainly this rank speculation does not clear the Daubert bar when it is expressed in the form of “hope.” 

    Plaintiff pointed to Stigliano v. Connaught Labs., Inc., which held that “treating doctors may testify about their diagnosis and treatment of [a patient’s] disorder, including their determination of that disorder’s cause.” 

    All Robinton offered was “hope that the present complaints and findings are related to a concussion”—far from a medical conclusion or diagnosis. The Court held that Stigliano, its progeny, and any cases interpreting New Jersey’s rules of evidence are entirely inapplicable to the question of whether Robinton’s testimony can be admitted. Moreover, even under Stigliano, Robinton’s testimony could not be admitted. His remarks regarding a possible concussion are not a “diagnosis,” but merely conjecture.

    Held

    The Court granted Defendants Flavors C. and Ricardo Ralat’s motion to preclude John Robinton’s testimony.

    Key Takeaway:

    To be admissible, an expert must base the conclusions of her testimony on “‘methods and procedures of science’ rather than on ‘subjective belief or unsupported speculation.’” Any testimony by Robinton that the accident caused an injury which triggered Plaintiff’s symptoms would constitute precisely the kind of “subjective belief or unsupported speculation” contemplated by Daubert to be in violation of Rule 702

  • Statistics Expert Witness’ Potential Backpay Calculation Excluded

    Statistics Expert Witness’ Potential Backpay Calculation Excluded

    Named Plaintiffs Mary Alice Clark, Christopher Coulter, Aaron Perez, Kevin Nelson and Phillip Roscher (collectively, “Plaintiffs”), individually and on behalf of all others similarly situated, brought this putative collective action against Defendant Capital Vision Services, LLC d/b/a MyEyeDr (“MyEyeDr” or the “Company”), claiming that MyEyeDr misclassified all General Managers (“GMs”) and General Managers-in-Training (“GMITs”) as exempt from the overtime pay requirements imposed by the federal Fair Labor Standards Act (“FLSA”), as well as Massachusetts and Pennsylvania law.

    MyEyeDr filed a motion to exclude Plaintiffs’ proffered expert witness, Dr. Liesl M. Fox under Fed. R. Evid. 702 and 403.

    Statistics Expert Witness

    Liesl M. Fox, Ph.D. is a Senior Consultant and Partner at Quantitative Research Associates, a firm that provides statistical and computing consulting services. She has been a statistical consultant for over twenty-five years, including conducting analyses in the fields of litigation and medical research, and has testified as an expert witness.

    Furthermore, she has consulted on and testified in numerous matters involving wage-and-hour disputes, including claims under the Fair Labor Standards Act of 1938 (“FLSA”). These matters have involved allegations of unpaid overtime, off-the-clock work, employment misclassification, minimum wage violations, time-shaving, record-keeping violations, and other wage-and-hour issues.

    Get the full story on challenges to Liesl Fox’s expert opinions and testimony with an in-depth Challenge Study. 

    Discussion by the Court

    Reliability

    Initially, MyEyeDr challenged Fox’s opinions on several grounds. As to the calculation of potential backpay, she assumed that all of the GMs’ training last eight weeks when there was testimony from MyEyeDr’s Chief Revenue Cycle Officer that such period could be shortened, and two class members for which she had made such calculation, testified that neither undertook such training and others testified to a shorter training period.

    Consequently, the Court held that the fact that Fox’s calculation for backpay were premised on such unsupported assumptions undermined the reliability of those calculations. Similarly, in her opinion regarding whether Plaintiffs supervised the equivalent of two full-time employees (for the purposes of determining if the executive exemption applied), the Court found that she did not account for inventory hours spent by these employees “which artificially deflated the labor hours GMs supervised.”

    Moreover, according to the Court, the key is that there is no explanation of a reliable methodology in which she included some work hours in her analysis and excluded others.

    Helpfulness to the Trier of Fact

    Next, the Court questioned whether Fox’s opinions will be helpful to the trier of fact.

    If MyEyeDr is found to have violated the FLSA, it would owe backpay for uncompensated overtime hours worked by GMs at a rate of one and a half times their hourly rate. Upon determining the number of overtime hours each GM worked, the jury would be tasked with calculating each individual’s hourly rate by dividing the weekly salary by the number of hours worked that week. To calculate the backpay, the jury would (1) multiply the hourly rate by one and a half and (2) multiply that by the GM’s overtime hours that given week. Such calculations constituted basic math that a jury can compute without the opinion of an expert.

    However, Plaintiffs noted that the payroll data in this case “contains more than 95,400 rows of data” spanning five years with “81 different earnings code[s] some of which are included in the damage calculations and others that are not properly included in the regular rate,” and “it contains unpaid and paid time off hours that need to be excluded from hours work estimates, and . . . bonuses that need to be spread over the time periods during which they are earned.” They argued that, given the enormity of the data, a jury is unlikely to have the ability to do these calculations. 

    Nevertheless, the Court held that such data can be presented in summary fashion to the jury. Plaintiffs may explain the meaning of such numbers through lay witnesses and argue the reasonable inferences that can be drawn from same to the jury. The Court decided that this proffered “opinion” did not require specialized knowledge or would be helpful to the jury as required under Fed. R. Civ. P. 702.

    Risk of Undue Prejudice and Confusion to the Jury

    Furthermore, the Court held that there is a risk that the jury will attach undue significance to this opinion offered by Fox based on the deficiencies addressed above, such that any probative value of same is outweighed by the risk of undue prejudice and confusion to the jury under Rule 403.

    Held

    In conclusion, the Court granted the Defendants’ motion to exclude Plaintiffs’ proffered expert witness, Liesl M. Fox.

    Key Takeaways:

    To begin with, MyEyeDr did not challenge Fox’s credentials as a highly qualified statistical consultant, or the general relevance of her proffered opinions, but challenged their reliability on several grounds and posited that her proposed testimony would be unhelpful to the jury.

    • First of all, Fox’s testimony would not assist the jury because Fox’s calculations are basic math that a jury can compute without the opinion of an expert.
    • Secondly, Fox’s calculation for backpay were premised on unsupported assumptions. For instance, Fox assumed that all of the GMs’ training lasted eight weeks when there was testimony from MyEyeDr’s Chief Revenue Cycle Officer that such period could be shortened.
