2 3 4 5 6 7 8 UNITED STATES DISTRICT COURT 9 SOUTHERN DISTRICT OF CALIFORNIA 10 11 UNITED STATES OF AMERICA, et al. ex rel. Case No.: 20cv286-W (MSB) Everest Principals, LLC, 12 ORDER DENYING DEFENDANTS’ Plaintiffs, 13 MOTION TO STRIKE v. 14 [ECF NO. 224] ABBOTT LABORATORIES, et al., 15 Defendants. 16 17 18 This is a qui tam case, wherein Plaintiff-Relator, Everest Principals, LLC (“Relator”) 19 maintains causes of action against Defendants Abbott Laboratories, Abbott Laboratories 20 Inc., Abbott Cardiovascular Systems Inc., and Abbott Vascular Inc. (collectively referred 21 to as “Defendants” or “Abbott”) on behalf of the United States of America and several 22 states for violations of the federal False Claims Act (“FCA”) and analogous state laws. 23 (ECF No. 85 at 6.) Relator is a limited liability company whose sole member was 24 employed by Defendants as a Therapy Development Specialist in its Structural Heart 25 Division from August 2015 to April 2017. (Id. at 7.) Defendants are involved in the 26 manufacturing and sale of medical devices, instruments, medications, and other health 27 care products. (Id. at 8.) 2 Rebuttal. (ECF No. 224, hereinafter “Motion to Strike.”) After reviewing letter briefs 3 lodged by the parties, the Court held Telephonic Discovery Conferences on October 6, 4 2025, and October 14, 2025, to address various issues pertaining to expert reports. (ECF 5 Nos. 216 & 219.) Following the conference, the parties jointly requested an opportunity 6 for formal briefing as to the Court’s tentative order striking the entire August 29, 2025, 7 report of Relator’s expert Dr. David Healy (“Healy Report”). (ECF No. 221.) For the 8 reasons outlined below, the Court DENIES Defendants’ Motion to Strike. 9 I. BACKGROUND 10 A. Defendants’ Motion to Strike 11 In short, Defendants argue the Healy Report should be stricken because it 12 improperly discloses affirmative expert opinions disguised as rebuttal opinions. (ECF 13 No. 224-1 at 2.) On August 29, 2025, the rebuttal report deadline, Relator disclosed Dr. 14 Healy for the first time. (Id.) The Healy Report contains two overarching opinions: (1) 15 “Abbott’s Therapy Awareness Programs lacked many of the qualities necessary to meet 16 an educational objective consistent with prevailing standards;” and (2) “Abbott’s 17 Therapy Awareness Programs . . . [were] inconsistent with accepted educational 18 standards” in other respects too. (Id. at 3 (citing Healy Report ¶¶ 14–15).) Defendants 19 contend that “none of Abbott’s opening reports contained any opinions whatsoever on 20 the subjects that Dr. Healy references.” (Id.) Moreover, Defendants argue that Dr. 21 Healy makes “textbook affirmative expert opinions that should have been disclosed, if at 22 all, by the June 30 [affirmative expert] deadline.” (Id. at 5.) 23 Defendants dispute Relator’s contention that Dr. Healy’s opinions are based on 24 the same subject matter as Defendants’ expert reports. (Id. at 5–6.) Instead, 25 Defendants assert that Abbott’s experts “opined that education was necessary and 26 explained why—not whether Abbott’s provision of education was or was not
27 appropriate as judged against the so-called ‘standards of medical education.’” (Id. 2 Dr. Anupam Jena—Defendants argue “none of those references contradict or rebut 3 evidence on the same subject matter identified in Abbott’s reports,” in violation of Rule 4 26(a)(2)(D)(ii). (Id. at 6–8.) Finally, Defendants contend striking the Healy Report is the 5 proper remedy because Relator cannot establish substantial justification or 6 harmlessness. (Id. at 9 (citing Yeti by Molly, Ltd. v. Deckers Outdoor Corp., 259 F.3d 7 1101, 1106 (9th Cir. 2001).) By disclosing Dr. Healy’s opinion on August 29 rather than 8 June 30, Defendants contend “Relator deprived Abbott of the opportunity to rebut [the 9 opinions].” (Id.) Further, Defendants claim Relator’s late disclosure harmed Defendants 10 by forcing them to divert attention from expert depositions and dispositive motions and 11 incur additional attorneys’ fees. (Id. at 10.) 12 B. Relator’s Opposition 13 In response, Relator argues the Healy Report is proper rebuttal testimony and 14 Defendants’ Motion to Strike should be denied. (ECF No. 225 at 2.) Relator alleges that 15 Defendants “seek[] an impermissibly narrow standard of what constitutes proper 16 rebuttal that prevents a rebuttal expert from challenging affirmative experts’ underlying 17 assumptions and methodology and presenting facts and data that they failed to 18 consider altogether.” (Id.) Further, Relator maintains that accepting Defendants’ 19 position “would turn the very purpose of rebuttal testimony on its head.” (Id.) 20 More specifically, Relator argues that the Healy Report contains proper rebuttal 21 testimony because it (1) addresses the same subject matter as Defendants’ affirmative 22 experts’ reports—namely, the purported medical education need and fulfillment of such 23 need by Abbott’s events—and (2) is intended solely to rebut Defendants’ affirmative 24 experts’ reports. (Id. at 4–5.) On June 30, 2025, Relator contends five of Defendants’ 25 medical experts offered affirmative opinions “on the supposed need for physician 26 education on the MitraClip and whether Abbott’s events were conducted in a manner to
27 meet that need.” (Id. at 5, 6–9.) Relator argues it served the Healy Report on August 2 Report is offered to show Defendants’ experts “consistently overlooked established 3 principles of professional learning, substituting personal impressions or anecdotal 4 experience for evidence-based evaluation.” (Id. at 10–11 (citing Healy Report ¶¶ 62– 5 63).) Furthermore, Dr. Healy’s Report shows that “Abbott’s events ‘deviated 6 substantially from the standards of legitimate medical education.’ ” (Id. at 11 (citing 7 Healy Report ¶¶ 62–63).) Even if the Court finds any of Dr. Healy’s opinions were 8 improper rebuttal, Relator argues the Healy Report was served before the discovery 9 cutoff, Dr. Healy’s deposition, and the final pretrial conference. (Id. at 11.) Thus, there 10 is time to cure any possible prejudice, and the appropriate relief would be to permit 11 Defendants to take Dr. Healy’s deposition and serve a rebuttal report in response to the 12 Healy Report. (Id.) 13 II. APPLICABLE LAW 14 Federal Rule of Civil Procedure 26 governs the disclosure of expert testimony. 15 “Unless otherwise stipulated or ordered by the court, this disclosure must be 16 accompanied by a written report—prepared and signed by the witness . . . .” Fed. R. Civ. 17 P. 26(a)(2)(B). The report must contain a “complete statement of all opinions the 18 witness will express and the basis and reasons for them,” as well as “the facts or data 19 considered by the witness in forming them.” Fed. R. Civ. P. 26(a)(2)(B)(i)–(ii). 20 Additionally, the report must include the witness’s qualifications and “a statement of 21 the compensation to be paid for the study and testimony in the case.” Fed. R. Civ. P. 22 26(a)(2)(B)(iv), (vi). “A party must make these disclosures at the times and in the 23 sequence that the court orders.” Fed. R. Civ. P. 26(a)(2)(D). 24 “A party need not disclose an expert within the deadline for initial expert reports, 25 and can instead disclose an expert as a ‘rebuttal expert,’ when the expert’s testimony is 26 ‘intended solely to contradict or rebut evidence on the same subject matter identified
27 by an initial expert witness.’” Clear–View Techs., Inc. v. Rasnick, No. 13-cv-02744-BLF, 2 because a broad reading that “encompass[es] any possible topic that relates to the 3 subject matter at issue . . . will blur the distinction between ‘affirmative expert’ and 4 ‘rebuttal expert.’” Vu v. McNeil–PPC, Inc., No. CV 09-1656 ODW (RZx), 2010 WL 5 2179882, at *3 (C.D. Cal.

Abbott Cardiovascular Sys., Inc., 2008 19 WL 4601038, at *1 (N.D. Cal. Oct. 15, 2008)). Further, a rebuttal expert report “is not 20 the time to change methodologies to account for noted deficiencies; instead, it is to 21 respond to criticisms of such methodologies.” Alvarez v. NBTY, Inc., No. 17-cv-00567- 22 BAS-BGS, 2019 WL 1353713, at *3 (S.D. Cal.

27 provides in relevant part: 2 Rule 26(a) or (e), the party is not allowed to use that information or witness to supply evidence on a motion, at a hearing, or at a trial, unless the failure 3 was substantially justified or is harmless. 4 Fed. R. Civ. P. 37(c)(1). The party facing sanctions bears the burden of proving 5 substantial justification or harmlessness. Yeti by Molly, Ltd., 259 F.3d at 1107. A district 6 court has “particularly wide latitude” in determining whether to issue sanctions under 7 Rule 37(c)(1). Id. at 1106. 8 III. DISCUSSION 9 A. Healy Report 10 On August 29, 2025, Relator produced the Healy Report, purportedly rebutting 11 five of Defendants’ affirmative expert reports.1 Dr. Healy is a Clinical Professor of 12 Anesthesiology and the Assistant Dean for Continuing Medical Education (“CME”) and 13 Lifelong Learning at the University of Michigan Medical School. (Healy Report ¶ 5.) Dr. 14 Healy notes he was retained by Relator to respond to Defendants’ affirmative experts’ 15 opinions “concerning medical education provided by Abbott’s therapy awareness 16 programs for the MitraClip device.” (Healy Report ¶ 1.) In doing so, Dr. Healy explains 17 he “addresses the standards of appropriate medical education, the characteristics of 18 activities that are inconsistent with medical education purposes, and whether the 19 therapy awareness programs, and more specifically the speaker programs and other 20 company-sponsored events . . . held by Defendants . . . met prevailing standards for 21 providing medical education.” (Id.) Dr. Healy states that “[a]s an expert witness, I 22 evaluate whether educational activities meet accepted professional standards, are free 23 from commercial bias, and are designed to promote improved clinical care.” (Healy 24 Report ¶ 12.) The Healy Report contains two principal opinions: (1) “Abbott’s Therapy 25 Awareness Programs lacked many of the qualities necessary to meet an educational 26
27 2 Programs” were otherwise “inconsistent with accepted educational standards.” (Healy 3 Report ¶¶ 14–15.) Dr. Healy references five of Defendants’ expert reports, which are 4 summarized below. 5 B. Makar Report 6 In a footnote, Dr. Healy claims to rebut parts of Dr. Moody Malak Makar’s June 30 7 Report (“Makar Report”). (See Healy Report ¶ 37 n. 6.) Dr. Makar is “an 8 echocardiographer and cardiac anesthesiologist.” (See Makar Report at 1.) Dr. Makar 9 was retained by Defendants “to opine on various topics relating to echocardiography 10 and the MitraClip procedure.” (Id.) Relevant to the instant dispute, Dr. Makar 11 concluded: “heart teams at new implanting sites need to be trained on how to perform 12 the MitraClip procedure and diagnose appropriate patients for the procedure.” (Makar 13 Report ¶ 3.) 14 Relator argues Dr. Healy rebuts Dr. Makar’s “opinions about ‘medical education 15 generally’ because the ‘technical device training’ Dr. Makar discusses is fundamentally 16 distinct from Abbott’s speaker programs, which Dr. Makar does not address 17 specifically.” (ECF No. 225 at 8 (citing Healy Report ¶ 37 n. 6).) Dr. Healy acknowledges 18 “Dr. Makar does not address Abbott’s speaker programs at all, and his Report provides 19 no evidence that those programs were legitimate educational activities.” (Healy Report 20 ¶ 37 n. 6.) Moreover, Dr. Healy opines that an article Dr. Makar relies on “does not 21 support Dr. Makar’s position” and instead “demonstrates how far Abbott’s programs fall 22 from established standards of medical education.” (Id.) 23 C. Bolling Report 24 Similarly, Dr. Healy addresses paragraph 2.A of Dr. Steven Bolling’s June 30 Report 25 (“Bolling Report”) in a footnote. (See Healy Report ¶ 37 n. 7.) Dr. Bolling is a cardiac 26 surgeon who was retained by Defendants “to opine on the impact of MitraClip on
27 treatment for degenerative mitral regurgitation, including the education necessary to 2 (Bolling Report at 1.) Dr. Bolling concluded: “Because MitraClip was an innovation, it 3 was not well-known or well-understood when it was approved, thus, there has been an 4 unmet need that persisted as many patients who could have benefited from the device 5 were not appropriately referred.” (Bolling Report ¶ 2.A.) 6 Relator argues Dr. Healy rebuts Dr. Bolling’s medical education opinions by 7 explaining Dr. Bolling “assumes, without analysis, . . . that Abbott’s speaker programs 8 satisfied this educational role.” (ECF No. 225 at 8 (citing Healy Report ¶ 37 n. 7).) Dr. 9 Healy also remarks on how Dr. Bolling did not “examine their design, content, 10 interdependence, or effectiveness” or “distinguish between accredited CME and 11 promotional speaker events.” (Healy Report ¶ 37 n. 7.) Further, Dr. Healy opines that 12 Dr. Bolling conflates two issues: “the genuine need for physician education and the 13 question of whether Abbott’s programs constituted legitimate education.” (Id.) Dr. 14 Healy notes “literature makes clear that commercially influenced events often lack 15 independence and are less effective than independent, peer-reviewed CME activities.” 16 (Id.) 17 D. Urey Report 18 Next, Dr. Healy claims to rebut paragraphs 2.1 through 2.10 of Dr. Marcus Urey’s 19 June 30 Report (“Urey Report”). (See Healy Report ¶¶ 38–39.) Dr. Urey is a 20 “cardiologist who specializes in advanced heart failure, mechanical circulatory devices, 21 and the care of heart transplant patients.” (See Urey Report at 1.) Dr. Urey was 22 retained by Defendants “to opine on how mitral regurgitation patients are referred for 23 specialized evaluation and treatment, including with MitraClip, the role of industry- 24 sponsored events in educating healthcare providers involved in cardiac referral 25 pathways, the impact of MitraClip on the treatment of mitral regurgitation patients, and 26 the roles of the heart failure specialist in recommending, and the patient in choosing,
27 MitraClip.” (Id.) 2 necessary to ensure that patients are timely referred for vital treatments.” (ECF No. 225 3 at 7 (citing Urey Report ¶¶ 2.1–2.10.) First, Dr. Healy opines that Dr. Urey’s “assertion 4 that Abbott’s programs improved outcomes is unsupported” because “Dr. Urey provides 5 no evaluation data[,] does not examine whether the programs met accepted 6 educational standards,” and “relies primarily on his own experience as both a 7 participant and speaker at such events.” (Healy Report ¶ 38 (citing Urey Report ¶ 2.8).) 8 Additionally, Dr. Healy notes that “broader evidence” contradicts Dr. Urey’s conclusion. 9 (Healy Report ¶ 39.) For example, Dr. Healy says “[s]ystematic reviews consistently 10 show that didactic, commercially influenced programs do not improve long-term 11 knowledge retention or patient outcomes.” (Id.) Dr. Healy also found “Dr. Urey 12 overlooks the robust, independent sources of physician education, including CME, peer- 13 reviewed literature, and professional society guidelines.” (Id.) 14 E. Reeves Report 15 Dr. Healy next addresses paragraphs 5.1 through 5.7 of Dr. Ryan Reeves’ June 30 16 Report (“Reeves Report”). (See Healy Report ¶¶ 40–43.) Dr. Reeves is “a board- 17 certified cardiologist who specializes in cardiovascular medicine and interventional 18 cardiology.” (See Reeves Report at 1.) He was retained by Defendants “to opine on the 19 disease state of mitral regurgitation and its treatment, including treatment with 20 Abbott’s MitraClip device, the role of physician education and referrals in the selection 21 of proper MitraClip patients, and the role of an interventional cardiologist in evaluating 22 a patient for, and implanting, MitraClip.” (Id.) Regarding medical education, Dr. Reeves 23 concluded: “It is important to educate clinical cardiologists so that they can identify 24 appropriate candidates for evaluation by a heart team early enough to give the patient 25 the best outcome.” (Reeves Report ¶ 5.) 26 Relator argues the Healy Report rebuts the Reeves Report in several ways. (ECF
27 No. 225 at 6–7.) First, Dr. Healy explains, “Dr. Reeves assumes that Abbott’s therapy 2 Reeves Report ¶¶ 5.1–5.7).) Dr. Healy continues, “Dr. Reeves does not examine 3 whether the programs were based on documented educational needs, whether the 4 content was balanced and evidence-based, whether multidisciplinary perspectives were 5 included, or whether outcomes were assessed.” (Healy Report ¶ 40.) Further, Dr. Healy 6 opines Dr. Reeves does not “distinguish between accredited CME and company- 7 controlled promotional events.” (Id.) Finally, Dr. Healy observes that Dr. Reeves “makes 8 no reference to the wide variety of high-quality, unbiased continuing education that was 9 readily available to physicians.” (Id. ¶ 41.) Dr. Healy also criticizes two of the sources 10 Dr. Reeves relies on and opines that “Dr. Reeves disregards well-established evidence 11 showing that didactic, commercially influenced events are both less effective and more 12 susceptible to bias.” (Id. ¶¶ 42–43.) 13 F. Jena Report 14 Finally, Dr. Healy claims to rebut Dr. Anupam B. Jena’s June 30 Report (“Jena 15 Report”). (See Healy Report ¶¶ 47–49.) Dr. Jena is a physician specializing in internal 16 medicine and an economist specializing in, among other things, the economics of 17 physician behavior, healthcare productivity, and medical innovation. (See Jena Report 18 ¶¶ 1–3.) Dr. Jena determined that “[e]ducation plays a legitimate and necessary role in 19 spreading awareness and helping physicians identify appropriate candidates, 20 particularly for novel therapies such as MitraClip.” (Jena Report ¶ 94.) Further, Dr. Jena 21 concluded “one must isolate the effect of the alleged kickback from the legitimate and 22 beneficial impact of physician education provided during Abbott’s MitraClip events.” 23 (Id.) 24 Dr. Healy attempts to rebut Dr. Jena’s opinions that “education was essential for 25 adoption of MitraClip,” “Abbott’s speaker programs provided meaningful education,” 26 and “any evaluation of improper influence must ‘isolate’ the educational benefit of
27 these programs.” (Healy Report ¶ 48).) Dr. Healy opines that Dr. Jena’s reasoning is 2 that describing Abbott’s programs “as education lowers the threshold for what qualifies 3 as education below accepted professional norms.” (Id.) Furthermore, Dr. Healy notes 4 that the Jena Report “relies on participant testimony that physicians discussed clinical 5 data and cases at these events;” however, Dr. Healy opines “informal case discussions in 6 a promotional environment do not transform the activity into legitimate education.” 7 (Healy Report ¶ 46 n. 16.) 8 G. Analysis 9 Under Federal Rule 26(a)(2)(D)(ii), an expert report qualifies as a rebuttal report if 10 it “is intended solely to contradict or rebut evidence on the same subject matter 11 identified by another party under Rule 26(a)(2)(B) or (C).” Fed. R. Civ. P. 26(a)(2)(D)(ii). 12 Accordingly, the Court must assess: (1) whether the Healy Report addresses the same 13 subject matter as the initial reports it purportedly rebuts; and (2) whether the Healy 14 Report “is intended solely to contradict or rebut evidence” in the initial reports. See 15 Leadership Stud., Inc. v. Blanchard Training & Dev., Inc., No. 15cv1831, 2018 WL 16 1989554, at *10 (S.D. Cal. Apr. 27, 2018) (citing Fed. R. Civ. P. 26(a)(2)(A) & (D)(ii)), 17 report and recommendation adopted, No. 15cv1831, 2018 WL 3752373 (S.D. Cal. Aug. 7, 18 2018). 19 Relator generally contends the Healy Report responds to the same subject matter 20 as Defendants’ affirmative expert reports: “the purported medical education need 21 provided by Abbott’s events.” (ECF No. 225 at 4.) By contrast, Defendants argue their 22 affirmative experts “opined that education was necessary and explained why—not 23 whether Abbott’s provision of education was or was not appropriate as judged against 24 the so-called ‘standards of medical education.’” (ECF No. 224-1 at 5–6 (citing Healy 25 Report ¶ 47).) In comparing the Healy Report against Defendants’ five affirmative 26 expert reports, the Court finds Defendants’ arguments to be more persuasive. Although
27 the Healy Report addresses the same general subject matter (medical education) as 2 the subject matter at issue, it will blur the distinction between ‘affirmative expert’ and 3 ‘rebuttal expert.’ More importantly, such broad reading of Rule 26(a)(2)(C)(ii) will 4 render the scope of the subject matter limitless and will lead to unjust results.”); see 5 also Tubio v. Adidas Am. Inc., No. CV 22-6424 GW (PVCX), 2024 WL 1191051, at *2 (C.D. 6 Cal. Feb. 5, 2024) (“[M]erely opining on the same general subject manner does not 7 qualify as a rebuttal report if the report does not explicitly rebut and contradict the 8 same evidence relied on by the expert report it seeks to rebut.”); Fed. Trade Comm'n v. 9 Qualcomm Inc., No. 17-CV-00220-LHK, 2018 WL 6522134, at *4 (N.D. Cal. Dec. 11, 2018) 10 (“However, a rebuttal expert does not receive carte blanche to address the broad 11 subject matter of the case, but rather to ‘contradict or rebut evidence on the same 12 subject matter’ as the other party’s expert report.”) (internal citations omitted). 13 After a thorough review of the relevant reports, the Court finds the Healy Report 14 is not “intended solely to contradict or rebut evidence on the same subject matter” as 15 Defendants’ affirmative expert reports, as required by Rule 26. See Fed. R. Civ. P. 16 26(a)(2)(D)(ii). Indeed, the Healy Report goes well beyond simply addressing the need 17 for “medical education” and advances two overarching opinions about Abbott’s 18 programs: (1) “Abbott’s Therapy Awareness Programs lacked many of the qualities 19 necessary to meet an educational objective consistent with prevailing standards;” and 20 (2) “Abbott’s Therapy Awareness Programs” were also “inconsistent with accepted 21 educational standards” in other respects. (Id. (citing Healy Report ¶¶ 14–15).) 22 However, as summarized above, none of Defendants’ affirmative experts opined directly 23 on whether Abbott’s programming met “prevailing” or “accepted” standards for medical 24 education. (See supra Sections III.B–F.) 25 For example, the Reeves Report concludes: “It is important to educate clinical 26 cardiologists so that they can identify appropriate candidates for evaluation by a heart
27 team early enough to give the patient the best outcome.” (Reeves Report ¶ 5.) In 2 included any hallmarks of bona fide educational activity.” (Healy Report ¶ 40.) Dr. 3 Healy admits “Dr. Reeves does not examine whether [Abbott’s] programs were based 4 on documented educational needs, whether the content was balanced and evidence- 5 based, whether multidisciplinary perspectives were included, or whether outcomes 6 were assessed.” (Id.) Thus, by Dr. Healy’s own admission, he does not address the same 7 subject matter as Dr. Reeves’ Report. 8 Similarly, the Urey Report concludes: “Industry-sponsored events improve patient 9 outcomes by providing education necessary to ensure that patients are timely referred 10 for vital treatments.” (Urey Report ¶ 2.) In response, Dr. Healy states that Dr. Urey’s 11 “assertion that Abbott’s programs improved outcomes is unsupported.” (Healy Report 12 ¶ 38.) However, Dr. Urey did not discuss whether “Abbott’s programs” qualified as CME 13 or otherwise met prevailing standards of medical education; instead, Dr. Urey 14 commented generally on “industry-sponsored events.” (See generally Urey Report ¶¶ 15 2.1–2.10.) Dr. Healy acknowledges “Dr. Urey provides no evaluation data and does not 16 examine whether [Abbott’s] programs met accepted educational standards,” thereby 17 admitting Dr. Urey addressed a different subject matter. (Healy Report ¶ 38.) 18 Additionally, the Bolling Report opines there was an unmet need even after MitraClip 19 was approved, but it does not opine that Abbott’s programs satisfied this educational 20 need. Compare Bolling Report ¶ 2.A (“Because MitraClip was an innovation . . . there 21 has been an unmet need that persisted as many patients who could have benefited 22 from the device were not appropriately referred”), with Healy Report ¶ 37 n. 7 (“Dr. 23 Bolling conflates two separate issues: the genuine need for physician education and the 24 question of whether Abbott’s programs constituted legitimate education”). 25 Rather than addressing Abbott’s experts’ opinions—namely, that education was 26 necessary for the MitraClip procedure and industry could generally play a role in
27 providing this education—Dr. Healy assessed the quality of Abbott’s programs. 2 trial of any information . . . that is not properly disclosed.” Yeti by Molly Ltd., 259 F.3d 3 at 1106 (citing Fed. R. Civ. P. 37(c)(1)). Belatedly disclosed evidence may be excused if it 4 is substantially justified or harmless. See Fed. R. Civ. P. 37(c)(1); Goodman v. Staples The 5 Off. Superstore, LLC, 644 F.3d 817, 826 (9th Cir. 2011). Even though the Court finds the 6 Healy Report exceeds the scope of proper rebuttal, the Court recognizes “[e]xcluding an 7 expert from testifying is a ‘Draconian sanction.’ ” People v. Kinder Morgan Energy 8 Partners, L.P., 159 F. Supp. 3d 1182, 1193 (S.D. Cal. 2016) (quoting Gibson v. Credit 9 Suisse AG, 2016 WL 81224, at *4, 2016 U.S. Dist. LEXIS 2088, at *13 (D. Idaho Jan. 7, 10 2016). Courts typically decline to exclude experts as a sanction where there is ample 11 time to depose the expert. See, e.g., In re Uber Techs., Inc., Passenger Sexual Assault 12 Litig., No. 23-MD-03084-CRB (LJC), 2025 WL 3653918, at *12 (N.D. Cal. Dec. 17, 13 2025); Andrews v. Plains All Am. Pipeline, L.P, No. CV 15-4113 PSG (JEMx), 2019 WL 14 6647928, at *5 (C.D. Cal. Nov. 22, 2019) (declining to strike where defendants would 15 “still have the opportunity to prepare responses . . . and depose these experts with an 16 extended deadline, thereby solving the problem short of striking the reports”); Downs v. 17 River City Group, LLC, No. 3:11-CV-00885-LRH-WGC, 2014 WL 814303, *8 (D. Nev. Feb. 18 28, 2014). 19 Here, the Healy Report was served on August 29, 2025, well before the cutoff of 20 expert discovery (October 24, 2025), the dispositive motions filing deadline (December 21 19, 2025), and the Final Pretrial Conference (April 27, 2026). (ECF No. 147.) Because no 22 trial date has been set, there is ample time to cure any possible prejudice. Thus, the 23 Court finds any failure to timely designate Dr. Healy as an affirmative expert was 24 substantially justified and harmless, and the striking of the Healy Report is not 25 warranted.
