HELEN GILLMOR, District Judge.
Plaintiff's Motion in Limine No. 1 seeks to exclude Defendants' expert, Dr. Stacey Hail, M.D., and her expert opinion relating to "excited delirium syndrome."
Dr. Hail is an Emergency Medicine Physician and a Medical Toxicologist certified by the American Board of Emergency Medicine and the American Board of Medical Toxicology. She is an Associate Professor in the Department of Emergency Medicine at the University of Texas Southwestern Medical Center at Dallas, Texas. She currently serves as an attending physician in the Parkland Hospital Emergency Department in Texas, which is a Level 1 Trauma Center and is represented to have the most emergency room visits of any single hospital in the United States. (Ex. A at p. 1, ECF No. 308-2).
Plaintiff makes two principal objections to Dr. Hail being called to testify as an expert witness.
Federal Rule of Evidence 702 provides that "scientific, technical, or other specialized knowledge" by a qualified expert is admissible if it will "help the trier of fact to understand the evidence or to determine a fact in issue." Fed. R. Civ. P. 702.
The United States Supreme Court held in
The Ninth Circuit Court of Appeals has explained that expert testimony is relevant if the evidence logically advances a material aspect of the party's case.
Causation is an extremely relevant issue in this case. To prevail in a Section 1983 action, the plaintiff must demonstrate that the defendant's conduct was the cause of the claimed injury.
Dr. Hail's expert report provides an opinion as to the Decedent's cause of death. Dr. Hail opines that the Decedent died from methamphetamine-induced Excited Delirium Syndrome. (Ex. A at p. 26, ECF No. 308-2). The report concludes that the Defendant Officers did not cause the Decedent's death. Dr. Hail's expert report states that the Decedent did not die from traumatic causes, nor from exposure to the Taser or exposure to OC spray, or due to restraint by the Defendant Officers.
Dr. Hail is qualified to provide a medical expert opinion as to cause of death. Dr. Hail has served as a medical expert witness in numerous cases. Several federal courts have certified Dr. Hail as a medical expert and admitted her expert opinion testimony concerning cause of death.
Plaintiff objects on the basis that Dr. Hail is not a pathologist and did not perform the autopsy of the Decedent. Plaintiff's argument is misplaced. Such an argument goes to the weight of the opinion, not the admissibility. A physical examination of the decedent is not required for an expert to be permitted to testify as to cause of death.
The inquiry is whether the expert has the qualifications based on his or her knowledge, skill, experience, training, or education.
Dr. Hail is qualified to render an expert opinion on cause of death based on her knowledge, skill, experience, training, and education.
The District Court's inquiry into an expert's admissibility pursuant to
The trial court is "supposed to screen the jury from unreliable nonsense opinions, but not exclude opinions merely because they are impeachable."
Plaintiff argues that Dr. Hail's conclusion that the Decedent died as a result of methamphetamine-induced Excited Delirium Syndrome should be excluded because it is not a recognized medical diagnosis by the American Medical Association, American Psychiatric Association, or the World Health Organization. Plaintiff's argument goes to weight, not admissibility. The district court is not tasked with deciding whether the expert is right or wrong, just whether the testimony has substance such that it would be helpful to the jury.
Dr. Hail's expert opinion is based on reliable data, principles, and methods. Fed. R. Evid. 702;
On September 10, 2009, the task force published a study that provides a review of the history and epidemiology of the syndrome, its clinical perspectives, potential pathophysiology, diagnostic characteristics, differential diagnoses, and clinical treatment. The study concludes, as follows:
The Eleventh Circuit Court of Appeals has explained that "`excited delirium' is a widely accepted entity in forensic pathology and is cited by medical examiners to explain the sudden in-custody deaths of individuals who are combative and in a highly agitated state."
The Ninth Circuit Court of Appeals has permitted district courts to rely on expert testimony regarding Excited Delirium Syndrome in granting police officers qualified immunity in Section 1983 cases.
Dr. Hail explains in her report that she reviewed a number of studies concerning Excited Delirium Syndrome including both the American College of Emergency Physician's White Paper and the National Institute of Justice's report from its Excited Delirium Syndrome Workshop Panel. The studies discuss the definition, epidemiology, pathophysiology, differential diagnosis, and acute treatment of Excited Delirium Syndrome and the common features of the syndrome. Dr. Hail reviewed the common features from the studies and compared them to those exhibited by the Decedent in rendering her opinion. Dr. Hail's methods are sufficiently reliable to allow her to provide an expert opinion.
Plaintiff objects to Dr. Hail's conclusion that the Decedent's death was caused by Excited Delirium Syndrome on the basis that it is a differential diagnosis rather than the result of a definitive diagnostic test. Plaintiff's objection is misplaced. The Ninth Circuit Court of Appeals has found that differential diagnosis is a common, reliable methodology under the
Plaintiff's challenges to Dr. Hail's expertise and opinions go to the weight of her opinion, but they do not provide a basis for exclusion of the testimony.
Plaintiff is permitted to cross-examine Dr. Hail on her conclusions, the reliability of the principles and methods she utilized, any conflicting expert testimony, and any contrary evidence in the record.
Plaintiff's Motion in Limine No. 1 To Exclude Testimony, Evidence, and Argument Regarding "Excited Delirium Syndrome" At Trial (ECF No. 266) is
Plaintiff's Motion in Limine No. 2 seeks to exclude Defendants' expert, Dr. Mark Kroll, Ph.D., and his expert opinion relating to Tasers and electrical weapons.
Plaintiff makes two principal arguments.
Dr. Kroll is a Biomedical Scientist with a specialty in bioelectricity, that is, interaction of electricity and the body. He has a Masters of Science and a Ph.D. in Electrical Engineering and is currently an adjunct full professor in biomedical engineering at California Polytechnic University and the University of Minnesota and a principal in Mark Kroll & Associated, LLC.
Dr. Kroll has been issued 370 U.S. patents and represents that he holds the most patents on electrical medical devices of anyone in the world. (Def.'s Ex. A, at p. 4, ECF No. 309-2). He is a Fellow of the American College of Cardiology, a Fellow of the Heart Rhythm Society, a Fellow of the IEEE Engineering in Medicine and Biology Society, and a Fellow of the American Institute for Medical and Biological Engineering. Dr. Kroll is the author of over 200 abstracts, papers, and book chapters and is also the co-editor of 4 books, including 2 scientific books on electrical weapons.
Dr. Kroll serves on numerous boards including the board for Taser International, Haemonetics, Prostracare, VivaQuant, and Recombinetics.
Plaintiff argues that Dr. Kroll should be precluded from testifying because he is a member of the Board for Taser International and is also the Chair of Taser International's Litigation Committee. Plaintiff's argument is misplaced. Plaintiff's argument goes to the weight and credibility of Dr. Kroll's testimony, not its admissibility. The Ninth Circuit Court of Appeals has explained that "as a general rule, bias is not a permissible reason for the exclusion of expert testimony."
Causation is a central issue in this case, specifically whether Defendant Chung's use of the Taser on the Decedent may have contributed to his death. Dr. Kroll has been certified to provide expert opinion on similar issues by numerous federal courts.
Dr. Kroll has the requisite training, skill, education, and experience to testify regarding the use of Tasers and the effect it may or may not have had on the Decedent. Kumho, 526 U.S. at 149; Wereb, 2011 WL 13279150, at *2.
Dr. Kroll conducted an audio analysis from the deployments of the Taser at issue in this case. Dr. Kroll developed a software tool which he used in his analysis. Dr. Kroll's expert report sets forth that the software he used is a widely accepted tool in biological and psychological research for sound analysis.
Dr. Kroll reviewed the audio signatures from the recording of the Taser deployments in this case. Dr. Kroll evaluated the sound emitted to determine if the Taser deployments resulted in an open circuit or an intact circuit to the Decedent. Dr. Kroll's report explains that an open-circuit occurs when a wire is broke, a probe misses, there is a clothing disconnect, or a probe is dislodged. The expert report opines that an open-circuit results in a louder sound and crackling being emitted from an electrical arc.
Dr. Kroll's report also reviewed the video from the Taser deployments. The report explains the effects the Taser would have had on the Decedent given the distances at issue in the videos Dr. Kroll asserts that Officer Chung's deployment of the Taser resulted in a maximum of 1 second of probe-mode electronic control to the Decedent.
Dr. Kroll's expert report cites to more than 150 authorities to support the scientific basis for his opinions. The Defendant Officers explain in their Opposition that one of the references is Dr. Kroll's publication "Significance of Sound During CEW Application" which is a peer-reviewed article. The article has received no negative comments and is published in a learned treatise. (Opposition at pp. 14-156, ECF No. 309).
The expert report states that Dr. Kroll's opinions were developed using well-recognized scientific disciplines, including bioelectricity, electrophysiology, and biomedical science, and that Dr. Kroll applied various qualitative and quantitative research methodologies as outlined in the report. (Def.'s Ex. A at pp. 26-33, ECF No. 309-2). Dr. Kroll's report satisfies the requirements of Fed. R. Evid. 702.
The soundness of the factual underpinnings and the correctness of Dr. Kroll's conclusions are matters for the jury, and do not go to the admissibility of his opinion.
Plaintiff's Motion in Limine No. 2 to Exclude Testimony And Report Of Dr. Mark Kroll, Ph.D. (ECF No. 267) is
Plaintiff's Motion in Limine No. 3 seeks to exclude Defendants from presenting evidence and argument regarding qualified immunity and the community caretaking doctrine.
Defendants oppose the Motion, in part. Defendants agree that it will not argue or use the term "qualified immunity" before the jury.
Defendants argue, however, that factual issues regarding qualified immunity are relevant and necessary issues for trial. Defendants also argue that issues regarding the Defendant Officers' community caretaking functions are relevant for trial.
On June 28, 2017, the District Court issued an Order denying the Defendant Officers' request for qualified immunity as to Plaintiff's claim for excessive force in violation of the Fourth Amendment to the United States Constitution. (ECF No. 224).
On July 10, 2018, the Ninth Circuit Court of Appeals issued an unpublished Memorandum decision. (ECF No. 241). The appellate court affirmed the district court's denial of qualified immunity and remanded for further proceedings. In its decision, the appeals court held that viewing the evidence in the light most favorable to the Plaintiff, there were factual issues as to whether the Defendant Officers used excessive force in deploying the Taser and the pepper spray against the Decedent.
The Defendant Officers filed a petition for certiorari to the United States Supreme Court that was denied on February 19, 2019. (ECF No. 252).
The doctrine of qualified immunity protects government officials from liability for civil damages insofar as their conduct does not violate clearly established statutory or constitutional rights of which a reasonable person would have known.
The second prong of determining if the right was "clearly established" is a matter of law to be decided by the Court.
The Ninth Circuit Court of Appeals construed the record in the light most favorable to the Plaintiff in its decision on qualified immunity. The appellate court did not find facts and there are no facts established for trial regarding qualified immunity. The appeals court specifically found that "there is a factual issue for the jury whether [Defendant Officers'] use of force violated both the Forth Amendment and clearly established law" which must be decided first before determining whether the Defendant Officers are entitled to qualified immunity.
The Ninth Circuit Court of Appeals did not find that the Defendant Officers could not raise qualified immunity at trial. Qualified immunity is a defense and the factual questions as to the Defendant Officers' actions is a question for the jury.
It is well established that police officers serve community caretaking functions that are separate from detection, investigation, or acquisition of evidence relating to violation of a criminal statute.
In its decision on appeal, the Ninth Circuit Court of Appeals addressed community caretaking in light of the arguments raised by the Parties.
Defendants are not precluded from arguing or presenting evidence during trial that they were engaged in community caretaking and acted reasonably given the severity of the circumstances during the incident on March 16, 2015.
Defendants are allowed to elicit evidence of the Officers' community caretaking function and the surrounding circumstances during the March 16, 2015 incident.

The Motion is
The Motion is
Plaintiff seeks to preclude Defendants from introducing evidence concerning the circumstances of Plaintiff's expert Richard Lichten's retirement from the Los Angeles County Sheriff's Department in 2008.
Defendants argue that Mr. Lichten engaged in surreptitious sexual misconduct including masturbating in a female employee's office after hours. Defendants assert the misconduct was the subject of a civil lawsuit, which Mr. Lichten settled. Defendants argue that Lichten was forced to resign because of the sexual misconduct complaint. Defendants argue that such evidence is relevant and request they be able to cross-examine Mr. Lichten about the misconduct for bias and credibility purposes.
Proof of bias is ". . . almost always relevant because the jury, as finder of fact and weigher of credibility, has historically been entitled to assess all evidence which might bear on the accuracy and truth of a witness' testimony."
Other federal courts have addressed the same issue regarding Mr. Lichten's retirement. Recently two separate federal district courts have found that evidence of Mr. Lichten's forced retirement is admissible as to his possible bias.
In
The Court recognizes that the details of Mr. Lichten's retirement are inflammatory and could confuse the jury and waste time on a collateral matter. Fed. R. Evid. 403.
The Court will permit the Parties to inquire of Mr. Lichten as to whether, at the time he retired, there was a complaint for misconduct against him. They could then ask if he retired in lieu of an investigation and they may inquire if he bears any ill will against the Los Angeles County Sheriff's Department or any other police department.
The Parties may not introduce evidence of or ask details about the complaint, the fact that it was sexual in nature, or otherwise offer evidence or argument pertaining to alleged misconduct unless for impeachment purposes. Defendants must raise any possible impeachment issue with the Court before it seeks to introduce such information before the jury.

The ruling on Plaintiff's Motion in Limine No. 5 is set forth in the Court's Order #3 on Motions in Limine.
Plaintiff's Motion in Limine No. 6 seeks to bar all eyewitness testimony except for the testimony of the Defendant Officers.
Plaintiff argues that eyewitness testimony of the subject incident is not relevant because reasonableness in an excessive force case is based upon the perspective of a reasonable officer on the scene, citing
Plaintiff appears to argue that testimony from any eyewitness who is a bystander or percipient witness is not admissible in excessive force cases. Plaintiff's argument is not well taken. Credibility is often an integral part of excessive force cases and eyewitness testimony is relevant and probative as to the respective Parties' version of events.
Eyewitness testimony from bystanders is relevant.
