MEMORANDUM OPINION AND ORDER
(Daubert Motion re: Bobby Shull, M.D.)
Pending before the court is the Motion to Exclude Certain General Opinions of
Bobby Shull, M.D. [ECF No. 2052] filed by defendants Johnson & Johnson and
Ethicon, Inc. (collectively “Ethicon”). The Motion is now ripe for consideration because
briefing is complete.
I.

Background

This case resides in one of seven MDLs assigned to me by the Judicial Panel
on Multidistrict Litigation concerning the use of transvaginal surgical mesh to treat
pelvic organ prolapse (“POP”) and stress urinary incontinence (“SUI”). In the seven
MDLs, there are more than 75,000 cases currently pending, approximately 30,000 of
which are in this MDL.
In this MDL, the court’s tasks include “resolv[ing] pretrial issues in a timely
and expeditious manner” and “resolv[ing] important evidentiary disputes.” Barbara
J. Rothstein & Catherine R. Borden, Fed. Judicial Ctr., Managing Multidistrict

Litigation in Products Liability Cases 3 (2011). To handle motions to exclude or to
limit expert testimony pursuant to Daubert v. Merrell Dow Pharmaceuticals, Inc.,
509 U.S. 579 (1993), the court developed a specific procedure. In Pretrial Order
(“PTO”) No. 217, the court instructed the parties to file only one Daubert motion per
challenged expert, to file each motion in the main MDL—as opposed to the individual
member cases—and to identify which cases would be affected by the motion. PTO No.
217, at 4.1
II.

Preliminary Matters

Before plunging into the heart of the Motion, a few preliminary matters need
to be addressed.
I am compelled to comment on the parties’ misuse of my previous Daubert
rulings on several of the experts offered in this case. See generally Sanchez v. Bos.

Sci. Corp., No. 2:12-cv-05762, 2014 WL 4851989 (S.D. W. Va. Sept. 29, 2014); Tyree
v. Bos. Sci. Corp., 54 F. Supp. 3d 501 (S.D. W. Va. 2014); Eghnayem v. Bos. Sci. Corp.,
57 F. Supp. 3d 658 (S.D. W. Va. 2014). The parties have, for the most part, structured
their Daubert arguments as a response to these prior rulings, rather than an
autonomous challenge to or defense of expert testimony based on its reliability and
relevance. In other words, the parties have comparatively examined expert testimony
and have largely overlooked Daubert’s core considerations for assessing expert

1 Ethicon

identified the Wave 1 cases affected by this Motion in its attached Exhibit A [ECF No. 20521], which the court has attached to this Memorandum Opinion and Order. At the time of transfer or
remand, the parties will be required to designate relevant pleadings from MDL 2327, including the
motion, supporting memorandum, response, reply, and exhibits referenced herein.

2

testimony. Although I recognize the tendency of my prior evidentiary determinations
to influence subsequent motions practice, counsels’ expectations that I align with
these previous rulings when faced with a different record are misplaced, especially
when an expert has issued new reports and given additional deposition testimony.
Mindful of my role as gatekeeper for the admission of expert testimony, as well
as my duty to “respect[ ] the individuality” of each MDL case, see In re

Phenylpropanolamine Prods. Liab. Litig., 460 F.3d 1217, 1231 (9th Cir. 2006), I refuse
to credit Daubert arguments that simply react to the court’s rulings in Sanchez and
its progeny. Indeed, I feel bound by these earlier cases only to the extent that the
expert testimony and Daubert objections presented to the court then are identical to
those presented now. Otherwise, I assess the parties’ Daubert arguments anew. That
is, in light of the particular expert testimony and objections currently before me, I
assess “whether the reasoning or methodology underlying the testimony is
scientifically valid” and “whether that reasoning or methodology properly can be
applied to the facts in issue.” Daubert, 509 U.S. at 592–93. Any departure from

Sanchez, Eghnayem, or Tyree does not constitute a “reversal” of these decisions and
is instead the expected result of the parties’ submission of updated expert reports and
new objections to the expert testimony contained therein.
Finally, I have attempted to resolve all possible disputes before transfer or
remand, including those related to the admissibility of expert testimony pursuant to

Daubert. Nevertheless, in some instances I face Daubert challenges where my
interest in accuracy counsels reserving ruling until the reliability of the expert

3

testimony may be evaluated at trial. At trial, the expert testimony will be tested by
precise questions asked and answered. The alternative of live Daubert hearings is
impossible before transfer or remand because of the numerosity of such motions in
these seven related MDLs. As these MDLs have grown and the expert testimony has
multiplied, I have become convinced that the critical gatekeeping function permitting
or denying expert testimony on decisive issues in these cases is best made with a live
expert on the witness stand subject to vigorous examination.
In the course of examining a multitude of these very similar cases involving
the same fields of expertise, I have faced irreconcilably divergent expert testimony
offered by witnesses with impeccable credentials, suggesting, to me, an unreasonable
risk of unreliability. The danger—and to my jaded eye, the near certainty—of the
admission of “junk science” looms large in this mass litigation.
The parties regularly present out-of-context statements, after-the-fact
rationalizations of expert testimony, and incomplete deposition transcripts. This,
combined with the above-described practice of recycling expert testimony, objections,
and the court’s prior rulings, creates the perfect storm of obfuscation. Where further
clarity is necessary, I believe it can only be achieved through live witness testimony—
not briefing—and I will therefore reserve ruling until the expert testimony can be
evaluated firsthand.
III.

Legal Standard

By now, the parties should be intimately familiar with Rule 702 of the Federal
Rules of Evidence and Daubert, so the court will not linger for long on these

4

standards.
Expert testimony is admissible if the expert is qualified and if his or her expert
testimony is reliable and relevant. Fed. R. Evid. 702; see also Daubert, 509 U.S. at
597. An expert may be qualified to offer expert testimony based on his or her
“knowledge, skill, experience, training, or education.” Fed. R. Evid. 702. Reliability
may turn on the consideration of several factors:
(1) whether a theory or technique can be or has been tested;
(2) whether it has been subjected to peer review and
publication; (3) whether a technique has a high known or
potential rate of error and whether there are standards
controlling its operation; and (4) whether the theory or
technique enjoys general acceptance within a relevant
scientific community.

Cooper v. Smith & Nephew, Inc., 259 F.3d 194, 199 (4th Cir. 2001) (citing Daubert,
509 U.S. at 592–94). But these factors are neither necessary to nor determinative of
reliability in all cases; the inquiry is flexible and puts “principles and methodology”
above conclusions and outcomes. Daubert, 509 U.S. at 595; see also Kumho Tire Co.

v. Carmichael, 525 U.S. 137, 141, 150 (1999). Finally, and simply, relevance turns on
whether the expert testimony relates to any issues in the case. See, e.g., Daubert, 509
U.S. at 591–92 (discussing relevance and helpfulness).
At bottom, the court has broad discretion to determine whether expert
testimony should be admitted or excluded. Cooper, 259 F.3d at 200.
IV.

Discussion

Dr. Shull is board-certified in obstetrics and gynecology and urology in female
pelvic medicine and reconstructive surgery. Dr. Shull is currently a professor of

5

obstetrics and genecology and urology at Northwestern University.
a. Alternative Designs and Products
Ethicon argues that Dr. Shull should not be permitted to testify that
alternative procedures are safer than Ethicon’s mesh products. Ethicon does not
challenge Dr. Shull’s qualifications or the reliability of this expert testimony; instead,
Ethicon challenges the relevance of this expert testimony. The relevance of this
expert testimony is better decided on a case-by-case basis. Accordingly, I RESERVE
ruling until trial.
b. Mesh Properties
Ethicon argues that Dr. Shull’s opinions concerning biomaterials—such as
mesh deformation, degradation, pore size, and weight—should be excluded because
Dr. Shull is unqualified and his opinions are unreliable.
As to qualifications, Ethicon argues that Dr. Shull is not a biomaterials or
toxicology expert and has never performed any degradation testing, among other
things. I find this argument without merit. An expert need not be a biomaterials
scientist to testify about the clinical effects of mesh. Dr. Shull is a urogynecologist
with experience treating patients with mesh complications. This clinical experience,
combined with Dr. Shull’s review of the relevant literature, qualifies him to opine on
mesh’s effect on and reaction to the human body. Ethicon’s Motion is DENIED on this
matter.
As to reliability, Ethicon wishes to exclude Dr. Shull’s statement that smallerpore, heavier-weight meshes intensify adverse reactions. Ethicon argues that this

6

testimony is inappropriate because Dr. Shull has not shown that an alternative
device—one with larger-pore, lighter-weight mesh—would have been equally
effective. But the challenged statement was not about the overall balance between
safety and efficacy or the appropriateness of an alternative design; Dr. Shull was
merely opining on adverse reactions. In its attempt to demonstrate a logical fallacy,
Ethicon has created its own. Ethicon’s Motion on this point is DENIED.
c. Design
Ethicon claims Dr. Shull is not qualified to offer what Ethicon characterizes as
design opinions. But they do not explain or identify design opinions with sufficient
specificity. This most recent wave of Daubert motions in this MDL is plagued with
some confusion about what constitutes a design opinion. So some clarification is
necessary before proceeding.
At first glance, it seems Ethicon wants to prevent Dr. Shull from providing any
opinions that even mention the word “design.” But the mere utterance of a single
word is not an incantation that transforms an opinion about one thing into something
else.
A close, contextual reading of the transvaginal mesh cases where this issue has
been raised before reveals the heart of Ethicon’s objections. In this motion—and
several others—the plaintiffs argue that the expert at issue lacks the particularized
skill, knowledge, experience, education, or training that is necessary to provide
opinions about the process of designing a product. Opinions of this sort include, for
example, opinions about pre-marketing product testing and product development.

7

But upon review, I find Dr. Shull has not expressed any opinions about the process of
designing a product. So Ethicon’s Motion is DENIED as moot on this very limited
issue.
d. Warnings
Ethicon claims Dr. Shull is not qualified to offer expert testimony about
product warnings, which includes expert testimony about the adequacy of the
relevant Instructions for Use (“IFU”). According to Ethicon, Dr. Shull is not an expert
in the development of warning labels and thus is not qualified to offer expert
testimony about warnings. Dr. Shull is not an expert in the development of warning
labels. While an expert who is an obstetrician and gynecologist may testify about the
specific risks of implanting mesh and whether those risks appeared on the relevant
IFU, the same expert must possess additional expertise to offer expert testimony
about what information should or should not be included in an IFU. Wise v. C. R.

Bard, Inc., No. 2:12-cv-1378, 2015 WL 521202, at *14 (S.D. W. Va. Feb. 7, 2015). Dr.
Shull does not possess the additional expertise to offer expert testimony about what
an IFU should or should not include. Accordingly, Dr. Shull’s expert testimony about
these matters is EXCLUDED.
e. Marketing
Ethicon seeks to exclude certain opinions on the ground that Dr. Shull is
unqualified to offer marketing opinions. Dr. Shull opines that “Ethicon
inappropriately marketed” its devices to “all physicians,” and “Ethicon formed a
special interest group with other mesh manufacturers to further market its prolapse

8

kits.” To the extent Dr. Shull seeks to offer opinions regarding Ethicon’s market
strategy and techniques, nothing in the record demonstrates that Dr. Shull possesses
any specialized knowledge, skill, or experience regarding marking practices. Further,
these opinions amount to discussions of corporate conduct and state-of-mind, which
have been consistently precluded. These opinions are EXCLUDED.
f. Opinions That Do Not Fit the Facts of the Case
Ethicon asks to court to exclude Dr. Shull’s expert testimony about
biomaterials that do not fit the facts of specific cases. But Ethicon paints with too
broad of strokes; it does not specify what opinions should be excluded from which
cases. Without details and context, I cannot rule on this issue, so Ethicon’s Motion is
DENIED on this point. In any event, a case-specific motion should be filed in the
specific case to which it applies.
V.

Recurring Issues

Many of the Daubert motions filed in this MDL raise the same or similar
objections.
One particular issue has been a staple in this litigation, so I find it best to
discuss it in connection with every expert. A number of the Daubert motions seek to
exclude FDA testimony and other regulatory or industry standards testimony. To the
extent this Motion raises these issues it is GRANTED in part and RESERVED in
part as described below.
I have repeatedly excluded evidence regarding the FDA’s section 510(k)
clearance process in these MDLs, and will continue to do so in these cases, a position

9

that has been affirmed by the Fourth Circuit. In re C. R. Bard, Inc., 81 F.3d 913,
921–23 (4th Cir. 2016) (upholding the determination that the probative value of
evidence related to section 510(k) was substantially outweighed by its possible
prejudicial impact under Rule 403). Because the section 510(k) clearance process does
not speak directly to safety and efficacy, it is of negligible probative value. See In re

C. R. Bard, 81 F.3d at 920 (“[T]he clear weight of persuasive and controlling authority
favors a finding that the 510(k) procedure is of little or no evidentiary value.”).
Delving into complex and lengthy testimony about regulatory compliance could
inflate the perceived importance of compliance and lead jurors “to erroneously
conclude that regulatory compliance proved safety.” Id. at 922. Accordingly, expert
testimony related to the section 510(k) process, including subsequent enforcement
actions and discussion of the information Ethicon did or did not submit in its section
510(k) application, is EXCLUDED. For the same reasons, opinions about Ethicon’s
compliance with or violation of the FDA’s labeling and adverse event reporting
regulations are EXCLUDED. In addition to representing inappropriate legal
conclusions, such testimony is not helpful to the jury in determining the facts at issue
in these cases and runs the risk of misleading the jury and confusing the issues.
Insofar as this Motion challenges the FDA-related testimony discussed here, the
Motion is GRANTED.
A number of experts also seek to opine on Ethicon’s compliance with design
control and risk management standards. Some of this testimony involves the FDA’s
quality systems regulations, and some—likely in an attempt to sidestep my

10

anticipated prohibition on FDA testimony—involve foreign regulations and
international standards. I find all of this proposed testimony of dubious relevance.
Although these standards relate to how a manufacturer should structure and
document risk assessment, the standards do not appear to mandate any particular
design feature or prescribe the actual balance that must be struck in weighing a
product’s risk and utility. Nor is it clear that the European and other international
standards discussed had any bearing on the U.S. medical device industry when the
device in question was being designed.
Nevertheless, because the nuances of products liability law vary by state, I will
refrain from issuing a blanket exclusion on design process and control standards
testimony, whether rooted in the FDA or otherwise. Each standard must be assessed
for its applicability to the safety questions at issue in this litigation, consistent with
state law. I am without sufficient information to make these findings at this time.
Accordingly, I RESERVE ruling on such matters until a hearing, where the trial
judge will have additional context to carefully evaluate the relevance and potential
prejudicial impact of specific testimony.
Similarly, I doubt the relevance of testimony on the adequacy of Ethicon’s
clinical testing and research, physician outreach, or particular product development
procedures and assessments otherwise not encompassed by the above discussion.
Again, such matters seem to say very little about the state of the product itself (i.e.,
whether or not it was defective) when it went on the market. But because the scope
of relevant testimony may vary according to differences in state products liability law,

11

I RESERVE ruling on such matters until they may be evaluated in proper context at
a hearing before the trial court before or at trial.
Additional—and more broad—matters also warrant mention. While some of
these concerns may not apply to this particular expert, these concerns are raised so
frequently that they are worth discussing here.

First, many of the motions seek to exclude state-of-mind and legal-conclusion
expert testimony. Throughout these MDLs, the court has prohibited the parties from
using experts to usurp the jury’s fact-finding function by allowing testimony of this
type, and I do the same here. E.g., In re C. R. Bard, Inc., 948 F. Supp. 2d 589, 611
(S.D. W. Va. 2013); see also, e.g., United States v. McIver, 470 F.3d 550, 562 (4th Cir.
2006) (“[O]pinion testimony that states a legal standard or draws a legal conclusion
by applying law to the facts is generally inadmissible.”); In re Rezulin Prods. Liab.

Litig., 309 F. Supp. 2d 531, 546 (S.D.N.Y. 2004) (“Inferences about the intent and
motive of parties or others lie outside the bounds of expert testimony.”). Additionally,
an expert may not offer expert testimony using “legal terms of art,” such as
“defective,” “unreasonably dangerous,” or “proximate cause.” See Perez v. Townsend

Eng’g Co., 562 F. Supp. 2d 647, 652 (M.D. Pa. 2008).
Second, and on a related note, many of the motions seek to prohibit an expert
from parroting facts found in corporate documents and the like. I caution the parties
against introducing corporate evidence through expert witnesses. Although an expert
may testify about his or her review of internal corporate documents solely for the
purpose of explaining the basis for his or her expert opinions—assuming the expert

12

opinions are otherwise admissible—he or she may not offer testimony that is solely a
conduit for corporate information.

Third, many of the motions also ask the court to require an expert to offer
testimony consistent with that expert’s deposition or report or the like. The court will
not force an expert to testify one way or another. To the extent an expert offers
inconsistent testimony, the matter is more appropriately handled via crossexamination or impeachment as appropriate and as provided by the Federal Rules of
Evidence.

Fourth, in these Daubert motions, the parties have addressed tertiary
evidentiary matters like whether certain statements should be excluded as hearsay.
The court will not exclude an expert simply because a statement he or she discussed
may constitute hearsay. Cf. Daubert, 509 U.S. at 595. Hearsay objections are more
appropriately raised at trial.

Finally, in some of the Daubert motions, without identifying the specific expert
testimony to be excluded, the parties ask the court to prevent experts from offering
testimony the expert is not qualified to offer. I will not make speculative or advisory
rulings. I decline to exclude testimony where the party seeking exclusion does not
provide specific content or context.
VI.
