    Discussion by the Court

    Elizabeth Thomson

    Thomson is qualified based on her twenty years of law enforcement experience and extensive training. For instance, she may testify regarding patterns in sexual assault cases due to her training, field experience, and six years of specialized service on a crisis intervention team. She may testify regarding police procedures based on her service as a homicide sergeant, where she developed and updated departmental policies and standard operating procedures.

    Defendants sought to limit Thomson’s testimony. First, they challenged her opinions regarding Nix’s and Keiner’s credibility as usurping the jury’s role. Specifically, they sought to preclude Thomson from testifying that Nix was truthful while Keiner was not, or from characterizing the parties’ statements as “consistent” or “inconsistent.”

    Nix contended that Thomson did not make credibility determinations but instead applied her investigative expertise to identify “consistencies and inconsistencies” in the parties’ statements. The Court is not persuaded. Even when framed in these terms, such testimony effectively invites the jury to conclude that accounts deemed “consistent” are credible, while those labeled “inconsistent” are not.

    Next, Defendants sought to preclude Thomson from testifying that the evidence is consistent with a nonconsensual sexual encounter. The Court declined to limit such testimony. Expert testimony offering “general and conditional opinions” about whether behavior aligns with patterns observed in sexual abuse cases is permissible.

    Finally, Defendants moved to preclude Thomson from testifying that Keiner was acting under “color of law” because such testimony would usurp the role of the jury. In this case, the Court found that Thomson’s proposed testimony—that Keiner was acting under “color of law” when he encountered Nix—did not usurp the jury’s fact-finding role. Jurors are unlikely to understand how police officers are trained to recognize whether they are acting under “color of law.”

    Andrea Taylor

    A. Taylor’s methodology is reliable under 702

    First, Keiner argued that Taylor’s methodology is unreliable under Rule 702. Taylor’s opinions are the product of a reliable methodology. She employed a multi-method approach to screen Nix for PTSD and CPTSD by administering seven diagnostic questionnaires and conducting two clinical interviews.

    The Court found Keiner’s arguments to the contrary unpersuasive. First, he argued that Taylor’s opinions are unreliable because she failed to use a Clinician-Administered PTSD Scale (“CAPS-5”) to diagnose Nix with PTSD “despite acknowledging CAPS-5 as the gold standard.” As discussed above, Taylor’s methodology is reliable because it is grounded in her professional experience. 

    Next, Keiner challenged Taylor’s conclusion that Nix has Complex PTSD because “Complex PTSD is not a distinct diagnosis under the DSM-5.” Taylor sufficiently explained each step of her analysis and the basis for her conclusions. The Court’s inquiry ends there.

    Keiner also argued that Taylor’s opinions are unreliable because she failed to perform any differential etiology or rule out alternative causes of Plaintiff’s PTSD symptoms. The Court disagreed. Differential etiology is simply one method of assessing causation in the medical context. Keiner’s assertion that Rule 702 “requires an expert to engage in a reasoned differential etiology” is unsupported.  Regardless, Taylor accounts for alternative causes of Nix’s symptoms and distinguishes between Nix’s baseline functioning and her post-incident decline. Taylor acknowledged Nix’s pre-existing anxiety and extensive trauma history, including childhood abuse and prior violence.

    B. Taylor’s methodology is based on sufficient facts and data under 702

    Keiner next argued that Taylor’s opinions are not based on sufficient facts or data under Rule 702.

    Taylor relied on sufficient facts and data here. She concluded, “to a reasonable degree of psychological certainty,” that the alleged sexual assault caused Nix’s PTSD and CPTSD symptoms. Taylor based that opinion on Nix’s “test results, symptom presentation, personal narrative, and trauma chronology,” and testified that her methodology was “standard” and grounded in her professional experience. The Court is satisfied that Taylor did not selectively “cherry pick” favorable facts but relied on the type of information reasonably considered by mental-health professionals conducting trauma assessments.

    Keiner claimed that Taylor improperly relied on Nix’s self-report without “independently verifying” the information through medical or therapy records, the Sexual Assault Nurse Examiner (“SANE”) exam, or other “objective” evidence. But the Court does not “require every expert to undertake an independent evaluation of the entire record to determine what he or she did or did not need to consider.” Taylor testified that it is “standard” to rely on self-reported symptoms to form diagnostic opinions—that is all the Court requires under 702.

    C. Portions of Taylor’s testimony are unhelpful under 702

    Finally, Keiner argued that portions of Taylor’s proposed testimony are not “helpful” under Rule 702. Specifically, Keiner challenged Taylor’s assertions that Nix was truthful in reporting the alleged assault; trauma victims “have no gain” in being untruthful; and gaps in Nix’s deposition testimony can be explained by dissociation or freezing.

    Taylor may not vouch for Nix’s truthfulness at trial. Taylor may not testify, for example, that Nix was truthful in reporting the incident or that inconsistencies in Nix’s account resulted from a trauma response. Those determinations remain within the exclusive province of the jury.  The Court also barred Taylor from opining that trauma victims “have no gain” in being untruthful—such testimony crosses the line into improper bolstering by suggesting that the jury should accept Nix’s account.

    This limitation did not preclude Taylor from testifying about the experiences and behaviors of trauma victims generally.

    Held

    • The Court granted in part and denied in part Defendants’ motion to exclude Elizabeth Thomson.
    • The Court granted in part and denied in part Defendants’ motion to exclude Andrea Taylor.

    Key Takeaway

    Expert testimony offering “general and conditional opinions” regarding patterns commonly observed in sexual-abuse victims is admissible. Taylor may testify, for example, that sexual-assault victims may experience memory lapses, dissociation, and freezing responses. Such testimony assists jury members in evaluating Nix’s testimony without telling them what to believe—an important distinction under 702.

  • Law Enforcement Expert Was Not Allowed to Opine on the Suspect’s Flight

    Law Enforcement Expert Was Not Allowed to Opine on the Suspect’s Flight

    Hakim Ledbetter was charged with: attempted possession with intent to distribute 500 grams or more of methamphetamine, 5 kilograms or more of cocaine, and 1,000 grams or more of PCP and aiding and abetting; possession of a firearm in furtherance of a drug trafficking crime; and possession of a firearm by a felon.

    The Government intended to present at trial evidence of Ledbetter’s flight, and “argue that his flight establishes his consciousness of guilt.”

    Ledbetter thus sought to introduce Chuck Rylant‘s testimony “regarding psychological and physiological factors that affect human responses to threatening stimuli,” so that the jury could “understand alternative reasons for flight in situations of perceived threat.”

    The Government moved in limine to exclude Rylant’s testimony, or in the alternative, for a pretrial Daubert Hearing, arguing that his opinion is irrelevant and inadmissible.

    Law Enforcement Expert Witness

    Chuck J. Rylant is a former police officer who has investigated and reviewed crimes of violence—including fights, attacks, and homicides—committed with various weapons.

    He earned a doctorate in clinical psychology in addition to completing numerous master’s level classes in psychology.

    Discussion by the Court

    Qualifications

    Rylant is not qualified to testify as to Ledbetter’s psychology. Rylant received his “Psy.D.” degree from “California Southern University,” an exclusively online, unaccredited school. While Rylant purports to be an expert on the psychological and physiological limitations of what humans are capable of, the defense presented nothing to establish that Rylant is trained to evaluate the psychological basis for a suspect’s flight from the police. Most of Rylant’s teaching and lecturing occurred when he had earned only an MBA degree—well before he received his “Psy.D.” in 2020.

    Rylant’s curriculum vitae confirmed that his specialty is limited to police use of force decisions and self-defense. Moreover, Rylant purportedly could not recall in how many federal criminal cases he was qualified to testify as an expert. Although he initially said that his “understanding” was five cases, he then acknowledged it was three. In those cases, he opined only on the decision to use force. Finally, Rylant acknowledged that he had never before offered an expert opinion on the psychological reasons for a person’s flight from police.

    This case does not concern whether police use of force was reasonable, but whether Ledbetter’s flight from police showed consciousness of guilt. In other words, Rylant’s “specialized knowledge” otherwise has nothing to do with Ledbetter or this case. His work on police use of force aside, Rylant has authored two series of books: one titled “How to Be Rich,” and the other, a jiu-jitsu primer.

    Reliability

    According to the Court, Rylant’s “expert report”—which he drafted in an hour—was exceedingly general, including virtually no mention of the facts of this case. Indeed, Rylant testified that he had essentially cut and pasted his Ledbetter report from strikingly similar reports he had prepared for other cases having nothing to do with flight from the police.

    Rylant did not base his “expert” opinion respecting flight from police on reliable methodology. Indeed, Rylant never explained his methodology.

    He never spoke with Ledbetter or anyone else about why Ledbetter fled. He never visited the neighborhood where Ledbetter was arrested. Indeed, although he purported to be uncertain, he apparently has never visited Philadelphia. Rylant offered no studies that he or anyone else conducted about flight from police.

    Fit – Rule 403

    It is apparent that the “fit” of Rylant’s opinion to Ledbetter is poor. He sought to opine that something (which he never clearly identified) other than consciousness of guilt could cause someone in Ledbetter’s circumstances to flee in the manner Ledbetter did. Yet, in forming this opinion, Rylant was ignorant of circumstances that could well have caused Ledbetter to flee from the police. On October 15, 2024, Ledbetter:

    • was in violation of his parole because he had left the state of Georgia
    • effectively possessed three loaded handguns;
    • as a parolee, and a convicted felon, was prohibited from possessing any weapons;
    • was driving a truck containing drugs valued at over $1 million;
    • had previously fled from police when they executed a warrant;
    • had previously been convicted of federal drug charges; and
    • had previously shot someone and been convicted of aggravated assault.

    Rylant then reluctantly acknowledged that this new information could have provided reasons for why someone in Ledbetter’s circumstances would run from police. The potential for prejudice and jury confusion arising from the Government’s “other reasons for flight evidence”—with its attendant cautionary instructions—would plainly outweigh the probative value of Rylant’s unreliable opinion, which he was not qualified to give.

    Rule 704

    Rule 704(b) still prohibits an expert from opining about the “possible” mental state of a Defendant. Accordingly, the Court determined that the defense’s attempt to end-run Rule 704(b) was impermissible.

    Held

    The Court ruled that because Chuck Rylant’s proffered opinion did not pass muster under Rules 702, 704, and 403, he could not testify at trial.

    Key Takeaway

    Although proffered to opine on Hakim Ledbetter’s psychology, Rylant is not and has never been a psychologist. His “Psy.D.” was conferred in 2020 by an unaccredited, exclusively online institution. He appears never to have testified, written, or lectured on the issue he was called to address: the psychology of a suspect fleeing from police. The three federal cases in which he purportedly testified bear no resemblance to Ledbetter. Rylant’s methodology is unknown.

    Although he purported to base his opinion only on generalities, he “revised” that basis and impermissibly strayed into his belief that Defendant lacked mens rea in fleeing from police. Admitting Rylant’s opinion would thus likely open the door to other explanations highly damaging to Ledbetter—about why he fled, as well as cautionary instructions, which would certainly confuse the jury.

  • Psychology Expert’s Testimony on the Grave Risk of Harm Admitted

    Psychology Expert’s Testimony on the Grave Risk of Harm Admitted

    Petitioner brought this action under the 1980 Hague Convention and the International Child Abduction Remedies Act, seeking the return of his minor child, S.A.M., to Switzerland. He alleged that Respondent wrongfully removed the child to Missouri in April 2025 without his consent and was unlawfully retaining custody.

    Asserting joint custody rights, Petitioner identified Switzerland as the child’s habitual residence and requested repatriation.

    Respondent raised affirmative defenses, claiming that the child’s return would pose a grave risk of physical or psychological harm or create an intolerable situation. She also invoked the Human Rights Exception of Article 20 of the Convention, arguing that the repatriation would violate the human rights and fundamental freedoms.

    Petitioner filed a motion to exclude the testimony of expert David Finn and to block a medical examination of the child.

    Discussion by the Court

    Petitioner moved to exclude David Finn’s testimony under Daubert v. Merrell Dow Pharms., Inc. and Federal Rules of Evidence 702, 401, and 403, because his opinions were unreliable, cumulative, based on selectively provided documents and unsupported by sufficient testing.

    Respondent opposed the motion to exclude. It was clear that Petitioner has failed to demonstrate Respondent acted outside her authority as the custodial parent in obtaining the examination of the minor child by Finn. Finn also reviewed the reports from the Department of Children and Family Services.

    Finn evaluated S.A.M. and reviewed all documents regarding S.A.M. Finding that Finn’s opinions were based on a sufficient factual foundation and methodological approach, the Court ruled his testimony admissible. While Petitioner’s concerns could impact credibility, they did not warrant exclusion and would be properly addressed through cross-examination.

    Held

    The Court denied the Petitioner’s motion to exclude the testimony of David Finn.

    Key Takeaway:

    The Court found Finn’s testimony admissible, supported by interviews and a review of documents, including Department of Children and Family Services reports.

    It held that the objections against Finn’s testimony concerned credibility, not admissibility, and could be addressed on cross-examination. Expert testimony, it emphasized, should only be excluded if so unsupported that it offers no help to the factfinder.

  • Psychology Expert Witness’ Testimony Assessing Causal Factors Leading up to a Suicide Admitted

    Psychology Expert Witness’ Testimony Assessing Causal Factors Leading up to a Suicide Admitted

    This case involved various claims arising from the death of SGT, a minor and former student at St. Marys Middle School in the Camden County School District. Plaintiffs alleged SGT died of suicide because of multiple bullying incidents at the school and Defendants’ failures to adequately respond to and address those incidents and asserted claims under the Americans with Disabilities Act (“ADA”) and Georgia law.

    Plaintiffs retained a psychology expert, Dr. Sheila Crowell, to opine on the causal chain of stressors leading to SGT’s suicide and SGT’s symptoms of ADHD. In her report, Crowell opined SGT experienced stress as a result of actions and inactions by staff at St. Marys Middle School and the cumulative nature of these stressors exceeded the typical level of stress most children encounter. 

    Crowell opined there was a clear precipitating event for SGT’s suicide on November 18, 2019. SGT made “origami rockets” for a classmate on November 15, 2019. The classmate threw the origami rockets in the math classroom, and one got stuck in the ceiling. On November 18, 2019, Jackson sent SGT to the “ownership room” for this incident.

    Crowell opined this event appeared to have been on the forefront of SGT’s mind on the day he died by suicide. In Crowell’s deposition, she detailed a process called “chain analysis.” “A chain analysis is where you go through the chain of events that led to a person harming themselves.”

    Defendants argued Crowell formed her opinions based on information that was narrowly focused on stressors SGT experienced at school, and Crowell did not sufficiently consider stressors outside the school. Defendants asked the Court to exclude Crowell’s opinions.

    Psychology Expert Witness

    Sheila Crowell is a tenured Psychology Professor at the University of Utah. She has been a licensed and practicing psychologist since 2013. Crowell has received funding from the American Foundation for Suicide Prevention and the National Institutes of Health to better understand and prevent suicide. Crowell has produced 115 peer-reviewed and invited publications, of which 30 publications deal directly with the topic of suicide or self-injury.

    Discussion by the Court

    Crowell’s Opinions Are Based on Reliable Methodology

    Defendants argued Crowell’s methodology was not reliable for two reasons. First, Defendants contended Crowell’s opinions are based solely on deposition testimony that was narrowly focused on stressors SGT may have encountered at school. Defendants argued SGT could have encountered other stressors, including discipline at home, interactions with peers outside of school, and SGT’s relationship with his parents, but Crowell did not consider these additional stressors in forming her opinions. Second, Defendants argued Crowell’s “chain analysis” was merely her subjective opinion.

    Crowell’s opinions are based solely on deposition testimony that was narrowly focused on stressors SGT may have encountered at school

    Crowell’s report and deposition testimony demonstrated that she reviewed numerous documents to determine which stressors contributed to SGT’s suicide. In addition to depositions from school administrators, Crowell considered SGT’s suicide note, SGT’s suicide video, an interview with SGT’s brother, and Plaintiff Kohn’s deposition.

    Crowell’s report and testimony showed that although she considered information about other stressors from outside of school, like SGT’s home life and parental discipline, she determined those stressors were not “proximal stressors” on the day of SGT’s suicide.

    The Court did not find that Defendants have shown Crowell’s opinions were improperly based on insufficient information.

    Crowell’s “chain analysis” was merely her subjective opinion

    The Court held that the Defendants’ second challenge regarding the reliability of Crowell’s chain analysis methodology is also unconvincing.

    Crowell has sufficiently explained the connection between her training and experience and her opinion that actions and inactions by staff at St. Marys Middle School likely increased SGT’s vulnerability to mental health struggles and led to SGT’s suicide. Defendants have not shown Crowell’s chain analysis is based on an unreliable methodology.

    Crowell relied on her training and experience as a clinical and research psychologist when she performed a chain analysis in this case. Crowell identified several documents she reviewed related to this case, including depositions, a forensic interview, and an academic article focused on youth suicide. After reviewing those materials, Crowell noted there was no evidence of any mental health support for SGT or any efforts to protect him from bullying.

    Crowell’s Opinions Will Assist the Trier of Fact

    Defendants argued causation is the “[t]he legal issue” in this case, and Crowell’s opinions would not assist the trier of fact in resolving that issue. According to the Defendants, Crowell’s opinions focused only on what happened immediately before the suicide, not long-term stressors, and, therefore, her opinions will not help the jury determine whether and to what extent other events could have contributed to SGT’s death.

    Defendants’ contention that Crowell’s opinions will not assist the trier of fact is unconvincing. The Court held that Crowell’s opinions concern the relevant time period for assessing causal factors leading up to a suicide and self-harm generally, and, specifically, concern the proximal stressors that may have contributed to SGT’s suicide. Crowell’s opinions on these topics arise from her specialized training and experience in psychology and assessing risk of self-harm and suicide (with special focus on risks for adolescents). Crowell’s opinions concern a core issue in this case—the cause of SGT’s suicide—and the opinions concern topics likely beyond the understanding of the lay person.

    Held

    The Court denied the Defendants’ motion to exclude the testimony of Sheila Crowell.

    Key Takeaway:

    • Crowell identified the “ownership room” incident as a clear precipitating event for SGT’s suicide, particularly because the “ownership room” probably had negative historical meaning for SGT. Crowell noted the “ownership room” incident occurred in the context of ongoing academic struggles.
    • Crowell’s opinions concern a core issue in this case—the cause of SGT’s suicide—and the opinions concern topics likely beyond the understanding of the lay person. Therefore, Crowell’s opinions would be helpful to the trier of fact.

  • Psychology Expert Witness Testimony Regarding Trauma Resulting from Alleged Racial Discrimination Limited

    Psychology Expert Witness Testimony Regarding Trauma Resulting from Alleged Racial Discrimination Limited

    Plaintiffs and Proposed Class Representatives Quinton Burns and K.B (collectively “Burns”) brought this action individually and on behalf of all similarly situated Black people against Defendants SeaWorld Parks & Entertainment, Inc. and SeaWorld Parks & Entertainment, LLC on account of the alleged racial discrimination that they suffered at Defendants’ property, Sesame Place Philadelphia (“Sesame Place”).

    Plaintiffs—Black and Hispanic parents and their children—allege that, when they visited the park, costumed character performers refused to interact with them in favor of similarly situated white children. Plaintiff retained, Michael L. Lindsey, to opine on “the extent to which racial discrimination, experienced by Plaintiffs, psychologically and traumatically impacted them” as well as “the therapeutic needs Plaintiffs will have over the course of their respective lifetimes.”

    Lindsey interviewed the named Plaintiffs and some of their family members and compiled reports of his observations. He conducted “each” of these interviews “exactly” according to an interview protocol that asked questions of both the children and parents in the room. The extensive script consisting of questions directed at the children who were allegedly discriminated against and their parents was prepared based on the criteria in the Diagnostic and Statistics Manual – 5 (“DSM-5”), the widely used taxonomy of mental health
    disorders. The DSM-5 contains diagnostic criteria for post-traumatic stress disorder (“PTSD”), which include the presence of certain “intrusion symptoms,” such as recurrent “distressing memories” or “[d]issociative reactions (e.g., flashbacks), and “persistent avoidance of stimuli associated with the traumatic event(s),” which can manifest as “efforts to avoid activities, places, or physical reminders” of the event, “[m]arkedly diminished interest or participation in significant activities,” or “[s]ocially withdrawn behavior.”

    Lindsey prepared reports about each family after conducting nine interviews of up to two hours each. Lindsey concluded that racism should be conceptualized as a toxic stressor associated with internalizing and externalizing behaviors, anger, conduct problems, and delinquent behaviors in adolescents and preadolescents or even should be considered a form of violence. Lindsey opined that the behavior exhibited by SeaWorld’s costumed characters by shunning and ignoring children of color was a representative example of institutional racism. Lindsey categorized the same as an adverse childhood experience (ACE) and recommended trauma-informed care for the traumatic experiences created by SeaWorld. Lindsey opined that SeaWorld was required to compensate the Plaintiffs for their immediate harm, allocate funds for the collateral mental and physical consequences of such experiences, and pay punitive damages to substantially and significantly discourage other similarly situated institutions from perpetuating such experiences.

    SeaWorld filed a motion to strike the report and testimony of Plaintiffs’ expert, Michael Lindsey.

    Psychology Expert Witness

    Michael L. Lindsey is a lecturer in the Psychology Department at Southern Methodist University in Dallas, Texas and the President of Nestor Consultants, Inc., which offers multiple services, including psychological evaluations and diversity trainings. He received a juris doctor from Villanova Law School and a PhD in Clinical Psychology from Hahnemann University. He has taught classes on, among other topics, developmental psychology, child psychology, research methods, and the role of ethics and diversity in psychology. He is a member of the American Psychological Association’s (“APA”) Law and Society Division and is a member of the planning committee for the International Academy of Law and Mental Health.

    Discussion by the Court

    SeaWorld initially argued that, because Lindsey was not a licensed psychologist and did not maintain a clinical practice, he was not qualified to deliver his opinions as a matter of law. The Court held that Lindsey’s lack of a professional license was not dispositive. And while Lindsey did not have a clinical practice, he had extensive experience both lecturing on and researching issues related to developmental psychology and consulting on the precise type of psychological issues relevant to his reports.

    SeaWorld maintained that Lindsey’s reports were not based on “any methodology . . . let alone a methodology” that satisfied Daubert and its progeny. Sea World contended that Lindsey failed to show a causal relationship between the alleged racial discrimination Plaintiffs suffered at Sesame Place and the trauma he says they have suffered. SeaWorld also found fault with Lindsey’s decision to interview the Plaintiff families in a group, without ever speaking with the children alone. Finally, SeaWorld took issue with Lindsey’s nearly identical recommendations that the Plaintiff Parents receive therapy.

    Lindsey’s reports contained three separate findings, the last of which drove his recommendations that the Plaintiffs receive therapy and, especially, punitive damages:

    1. His professional experience and the scientific literature showed that, in general, ACEs “may cause trauma.”
    2. When ACEs in general “do result in trauma,” they should be treated with trauma-informed care.
    3. Based on Lindsey’s “professional opinion,” SeaWorld had created traumatic experiences for the identified family members.

    Implicit in his final finding was: (1) that what allegedly happened to the Plaintiff Children at Sesame Place constituted ACEs; (2) that those ACEs were the sort, in general, that caused trauma; and (3) that those individual ACEs, in fact, caused trauma for the Plaintiff Children.

    The Court noted that the APA made it clear that Lindsey’s chosen method of assessment, a clinical interview, was a widely accepted tool and altough his script might not have constituted a “structured diagnostic interview” per the APA’s handbook, this technique, although subjective, can still be sufficiently scientifically grounded to be reliable considering the interview protocol included several questions to both sets of interviewees aimed at understanding what happened to the Plaintiff Children at Sesame Place, how it made them feel at the time, and how they have processed the events since, all of which would help Lindsey evaluate whether they constituted ACEs.

    Next, SeaWorld’s argued that Lindsey “neither provided nor followed any identifiable framework to assess which adverse experiences result in ‘trauma.’” The Court noted the lack of a reliable method to determine whether the ACEs that he identified caused trauma in the specific instances he was tasked with examining. Clinical interviews like the ones Lindsey conducted remained, in his view, the primary basis for determining whether an ACE had caused trauma, even though SeaWorld identified multiple peer-reviewed tests that can be used to measure trauma in both adults and children. However, it was seen that Lindsey’s interview protocol, albeit nonstandard, contained questions that plainly tracked the diagnostic criteria for PTSD contained in the DSM-5, which SeaWorld conceded was “the authoritative work on mental disorders. The Court held that it constituted a scientifically grounded means by which he could assess, in combination with his experience and review of the relevant scientific literature, whether the ACEs that the Plaintiff Children experienced are the type that would cause trauma.

    The Court noted that Lindsey’s findings shifted in scope from the general to the individual, concluding that “SeaWorld had created traumatic experiences for these identified family members” and concluded that Lindsey’s reports were not based in the scientific method in this respect. Although Lindsey’s interview protocol did contain plenty of questions that would have allowed him to elicit the Plaintiff Children’s emotions and how they then related to amusement parks, it did not contain any mechanism for isolating the causes of those sentiments. Lindsey failed to ask the Plaintiff Parents about their children’s psychosocial history and he admitted in his deposition that he did not review Plaintiffs’ videos of some of the interactions between the children and the costumed characters, which could have helped him better understand the severity of the ACEs being described. Nor can the scientific literature he cited bridge the gap at this step because these studies discuss the potentially traumatic impact of ACEs that involve racism, not the actual traumatic nature of the ACEs that Lindsey identified.  Henceforth, Lindsey was not permitted to testify about whether the ACEs he identified caused the symptoms of trauma that he observed.

    He could testify that, based on his scientifically based interview protocol, review of relevant scientific literature, and years of professional experience, the alleged discriminatory events at Sesame Place were ACEs likely to cause trauma. He could also testify that the Plaintiff Children’s symptoms were consistent with trauma and that many interviewees and their family members could benefit from therapy. However, he couldn’t solely attribute the observed symptoms to the alleged discrimination at Sesame Place.

    SeaWorld pointed out that Lindsey failed to “control for ‘suggestibility’—a cognitive bias concept in which a child’s response’s may be influenced or contaminated by what parents or older siblings said about the events in issue or their feelings about said events when it interviewed the Parent and Child Plaintiffs together. However, the Court determined that such concern implicated Lindsey’s credibility and was the province of the jury. Moreover, despite making essentially the same recommendation for every Plaintiff Parent, whether interviewed or not, Lindsey’s failure to engage in any “differentiation or . . . individualized analysis” did not warrant exclusion considering Lindsey’s reports consisted of unique narratives of the interviews he conducted, including the responses from both the child and parent interviewees that informed his conclusions that what happened to Plaintiffs at Sesame Place constituted an ACE, in addition to the materially identical recommendations.

    The Court, citing UGI Sunbury LLC v. A Permanent Easement for 1.7575 Acres, 949 F.3d 825, 832 (3d Cir. 2020), held that Daubert requires that an expert’s testimony must be “‘sufficiently tied to the facts of the case,’ so that it ‘fits’ the dispute and will assist the trier of fact.” SeaWorld argued that the necessary fit was missing there because Lindsey stopped short of diagnosing any Plaintiff with a condition listed in the DSM-5. The Court held that the question of whether therapy (with or without a DSM-5 diagnosis) would be beneficial was relevant to questions that the jury would have to evaluate at trial. However, Lindsey’s reports would not warrant exclusion given the “liberal” nature of the “fit” inquiry under Daubert.

    SeaWorld also identified multiple statements in Lindsey’s reports that it argued were otherwise inadmissible as a matter of law. Lindsey’s discussion of institutional racism included a legal conclusion that SeaWorld argued must be stricken: “SeaWorld, by their behaviors of shunning and ignoring children of color, are representative examples of” individual or institutional racism. SeaWorld argued that the same must happen to Lindsey’s discussion of damages, where he concluded that “SeaWorld must pay Plaintiffs for their immediate harm, allocate funds for the collateral mental and physical consequences of these experiences, and pay punitive damages to substantially and significantly discourage other similarly situated institutions from perpetuating such experiences.” The Court held that the definition of “institutional racism” that Lindsey tagged SeaWorld with there—including a description of “institutional discrimination” as something that “targeted specific, easily stereotyped, generalizable attributes of individuals”—implied that the company acted with a degree volition that steered his conclusion too close to an ultimate issue in this case. The Court also held that opining on the appropriateness of the punitive damages was a job for the fact finder, not an expert witness.

    Held

    Defendants’ Motion was granted in that Michael Lindsey was precluded from testifying on: (1) whether Defendants, its employees, or its agents were the cause of the trauma symptoms that he observed during his clinical interviews of Plaintiffs; (2) whether the alleged incidents of racial discrimination at Sesame Place Philadelphia constitute intentional discrimination; or, (3) whether Plaintiffs are entitled to punitive damages.  Lindsey’s opinions on these issues were stricken by the Court but Defendants’ motion to strike the testimony of Lindsey was denied in all other respects.

    The Court has not arrived on an outcome for this case since the remaining issues involved in this case still await resolution.

    Key Takeaways:

    SeaWorld initially contested Lindsey’s qualifications, citing his lack of a professional license and clinical practice. However, the Court determined that his extensive experience and expertise were sufficient, regardless of these factors. Additionally, SeaWorld challenged the methodology of Lindsey’s reports, arguing they lacked scientific basis. Despite this, the Court found his interview protocol and review of literature to be acceptable. Lindsey’s findings regarding trauma and therapy recommendations were upheld by the Court, although he couldn’t solely attribute symptoms to alleged discrimination. Concerns were raised about Lindsey’s use of the concept of “suggestibility” and the lack of individualized analysis, but the Court considered these matters of credibility for the jury to decide. The Court applied the Daubert standard to assess the admissibility of Lindsey’s testimony, allowing most of his reports to be admitted while ruling out some statements as inadmissible legal conclusions. SeaWorld’s objections regarding certain statements in Lindsey’s reports were upheld by the Court, affirming that determination of punitive damages is the role of the fact finder, not an expert witness. Overall, the text highlights the intricate process of evaluating expert testimony, with the Court meticulously scrutinizing Lindsey’s qualifications, methodology, and the admissibility of his reports and testimony.

    Court limits testimony of Marketing Expert Witness citing lack of experience analyzing consumer confusion from either a legal or marketing perspective in trademark infringement suit

    In the case involving Plaintiff Blue Bottle Coffee, LLC and Defendants Southern Technologies, LLC and Hui Chuan Liao, the Plaintiff, a coffee business, filed a lawsuit in August 2021 and an amended complaint in November 2021. The dispute centered on alleged trademark infringement and unfair competition claims. The Plaintiff held multiple registered trademarks, including two solely consisting of a shade of blue, Pantone 2995 C, and asserted trade dress in its product packaging.

    Defendants, who began using the name “Blue Brew” in 2017, were accused of selling coffee-related products with packaging and branding that closely resembled the Plaintiff’s, including the use of a similar shade of blue and the word “blue.”

    On April 7, 2023, the Plaintiff served three expert reports from Jeffrey S. Andrien, Norman Broadhurst; and Jill Morton. Jill Morton provided testimony regarding branding and the use of color in the case. On May 22, 2023, updated versions of these reports were provided to the Defendants. Jill Morton was deposed by the Defendants on July 20, 2023. Subsequently, on August 11, 2023, the Defendants filed a Daubert motion to exclude Jill Morton’s testimony challenging the reliability and relevance of each of Morton’s three conclusions and her corresponding analyses: (A) the color blue as a source-identifying attribute of Plaintiff’s brand, (B) the color blue that the parties used in connection with their brands was “similar or nearly identical”; and (C) the combined effect of the color blue and the word “blue” on Defendants’ products would cause consumer confusion with Plaintiff’s products.

    Marketing Expert Witness

    Jill Morton is the CEO of Colorcom, a consulting firm that “specializes in helping companies understand how to use color most effectively.” Morton received a Bachelor of Fine Arts from the University of California, Santa Barbara, where she also completed a fifth year of study in the Graduate School of Education. She also received a Master of Fine Arts in design from the University of Hawaii. As a color consultant, Morton leverages her extensive technical and professional knowledge about color to provide guidance on a diverse range of projects. Her expertise encompasses aspects such as the psychological impact of color, creative color combinations, harmonious color choices, visual ergonomics, and staying current with marketing trends. Morton applies these critical factors to offer successful solutions for her global clientele.

    Discussions by the Court 

    Jill Morton had a degree in Art Education and an MFA in design, along with over twenty years of experience as a “brand identity expert.” She had also taught courses on color at universities and colleges for over 20 years, including a graduate-level course on the psychological and physiological effects of color. The Court found her qualified to provide testimony regarding Plaintiff’s use of the color blue as a source-identifier, emphasizing the broad conception of expert qualifications under Rule 702.

    Defendants had argued that Morton’s qualifications were unreliable because she wasn’t a licensed psychologist or a scientist and hadn’t published peer-reviewed papers. However, Morton clarified that she referred to herself as a “color consultant” and only discussed psychology in the context of how it related to branding and consumer behavior, drawing from her extensive marketing experience. The Court agreed that her expertise was rooted in her marketing experience, and any questions about her qualifications went to the weight of her testimony, not its admissibility.

    Defendants also contested the reliability of Morton’s testimony because she didn’t conduct consumer surveys or interview Blue Bottle employees about their advertising strategies. Morton defended her opinion, stating that she relied on her experience advising brands on color and consumer associations. The Court agreed that the absence of surveys or interviews impacted the weight of her testimony but didn’t render it inadmissible.

    To prevail in a trademark infringement claim, the claimant needed to demonstrate the validity of their mark, which could be through federal registration, a suggestive mark, or secondary meaning in the market. Morton’s discussion about the functionality of blue in branding was relevant to the trademark infringement inquiry, as it related to the validity of the marks.

    Morton proceeded to assert that the shade of blue used by the Defendants on their packaging, Pantone 305 C, was “nearly identical” to the Blue Bottle Blue Marks, Pantone 2995 C. She emphasized her expertise in both Pantone and CMYK colors, backed by 20 years of experience in understanding how consumers perceive these color systems.

    To facilitate the jury’s evaluation of these color similarities, Morton conducted a Pantone color analysis. Pantone, a company and system for classifying colors, formulates mixing formulas for various shades. Morton provided a breakdown of the color ingredients for Pantone 2995 C (Blue Bottle Blue) and Pantone 305 C (Defendants’ blue) based on the Pantone Color Guide. She explained that these colors contained varying proportions of Pantone Pro Blue and Pantone Transparent White, which determined the degree of lightness for each shade.

    While Pantone 2995 C (Blue Bottle Blue) had a relatively small percentage of Pantone Ref Blue, Morton pointed out that it shared identical ingredients with Pantone 305 C (Defendants’ Blue) in terms of Pantone Pro Blue and Pantone Transparent White. Consequently, Morton concluded that the shades of blue were “similar or nearly identical.”

    Morton had also conducted a CMYK analysis, which is a color formula system for printing materials. It involves using varying percentages of cyan, magenta, yellow, and black to create specific shades of color. In her analysis, Morton compared the CMYK formulas for Plaintiff’s and Defendants’ shades of blue, using a Pantone guide called “Color Bridge by Pantone.” She found that both colors predominantly consisted of cyan, with only minimal amounts of other colors. Additionally, Morton analyzed two unrelated shades of blue, contrasting them with the Plaintiff’s and Defendants’ colors, noting that they contained more magenta and black.

    Defendants had primarily questioned the reliability of Morton’s CMYK analysis, contending that Plaintiff provided no evidence to establish the peer-reviewed or previously accepted nature of her particular CMYK analysis methodology. Morton had clarified that she used the CMYK analysis to translate and confirm the Pantone color composition and similarities she observed. Her approach didn’t involve mathematical analysis but consisted of commentary regarding the CMYK breakdown of four different shades of blue, including those of the Plaintiff and Defendants, all based on Pantone formulas.

    The Court held that in certain fields, Morton’s extensive experience was considered a primary basis for reliable expert testimony, citing Lucido v. Nestle Purina Petcare Co. Her analyses were conducted based on two decades of practical experience with these techniques, aimed at explaining why the two colors might appear similar to the human eye. Given the relatively specialized nature of color’s role in branding, her experience and method explanation were deemed adequate. Any concerns about the reliability of Morton’s analysis could be addressed through cross-examination.

    Morton had stated that she conducted the two color analyses with the purpose of assisting the jury in evaluating the similarities between the marks, as the “Similarity of marks” is a relevant factor in establishing the likelihood of confusion, one of eight factors considered in trademark infringement cases.

    Defendants had argued that there was no need for a “framework” for jurors to compare two colors, as the differences between Plaintiff’s BLUE BOTTLE BLUE Marks and the colors used by Defendants were obvious, and one didn’t need to be a “color psychologist” for such a comparison. Morton herself acknowledged that jurors who had passed some color vision test could perform the color comparison just as well as she could. However, the Court recognized that Morton’s testimony went beyond a mere side-by-side comparison. She delved into the ingredient breakdown of the two Pantone colors, especially considering Plaintiff’s trademark registrations specifically claimed Pantone 2995 C. Morton translated the Pantone ingredients into ink makeups for printing, aiming to provide a nuanced perspective on color and its components as seen from a professional color consultant.

    While jurors could assess color similarity on their own, the Court found that Morton’s expertise could be useful in providing a framework for color interpretation and offering insights into the similarities between Plaintiff’s and Defendants’ shades of blue. Therefore, the Court concluded that Morton was permitted to provide this framework and analyze color similarities based on her experience as a color consultant.

    Morton also relied on Blue Bottle’s longstanding use of its marks and the combined effect of the BLUE BREW brand’s use of a similar color and the word “blue” in its name to argue that there was a likelihood of consumer confusion. Defendants challenged her lack of experience analyzing actual instances of consumer confusion from either a legal or marketing perspective. The Court agreed with Defendants, stating that her testimony wouldn’t assist the trier of fact, as it was essentially a side-by-side comparison, and her determination usurped the role of the jury as factfinders.

    Held

    In conclusion, the Court granted the motion to exclude Morton’s testimony regarding the likelihood of confusion between Plaintiff’s and Defendants’ products but allowed her testimony in all other respects.

    Key Takeaways:

    This case illustrates several important considerations for expert witness testimony under the Daubert standard. First, reliability hinges on the expert’s qualifications and experience in their discipline. The Court found Morton qualified to testify about color and branding given her extensive background, though unqualified on consumer psychology. Second, helpfulness to the jury is key for relevance. Morton’s color analyses assisted the jury in evaluating trademark validity and similarity, but her opinion on consumer confusion usurped their role.  

    Third, methodology matters, especially for scientific testimony. Morton’s color analyses using standard systems were sufficiently reliable from her experience, but her “consumer confusion” analysis lacked sound methodology. Fourth, ultimate legal issues are off limits. Though experts can embrace ultimate factual issues like similarity, they cannot give opinions telling the jury the legal result to reach. Fifth, if in doubt, exclude under Rule 403. Expert opinions with weak methodology risk confusing or misleading jurors. 

    In summary, Daubert requires a flexible inquiry, but proponents must show experts are qualified, use reliable methodology, and provide opinions helpful to the jury without invading its role or confusing the issues. This helps ensure expertise reliably informs while preserving the jury’s fact-finding function.
