Lampton v. C R Bard Incorporated et al
ORDER granting in part and denying in part Doc. 51 Motion to Strike general opinions of Dr. Blackman; denying Doc. 53 motion to strike expert report of Dr. LaDisa. Signed on October 12, 2020 by District Judge Nanette K. Laughrey. (Opalach, Tessa)
IN THE UNITED STATES DISTRICT COURT
FOR THE WESTERN DISTRICT OF MISSOURI
C. R. Bard, INC. and BARD
PERIPHERAL VASCULAR, INC.,
Bard’s Motion to Strike the general opinions of Dr. Blackman, Doc. 51, is granted in part
and denied in part. Bard’s Motion to Strike the expert report of Dr. LaDisa, Doc. 53, is denied.
Dr. Blackman cannot rely on or incorporate in his own opinions, the specific portion of the
expert testimony of Dr. Hurst which was stricken by the MDL court. While Dr. Blackman may
be qualified to give the same opinion that was stricken by the MDL court, it would undermine
the MDL discovery process to permit specific causation experts to clean up evidentiary defects
found by the MDL court that caused it to exclude part of a general causation expert’s testimony.
Otherwise, the Motions are denied because Bard has not identified additional examples of
how it would be prejudiced merely because Dr. Blackman and Dr. LaDisa are incorporating
material developed by the MDL general causation experts into their specific causation opinions.
Bard acknowledges that Dr. Blackman and Dr. LaDisa can rely on general expert testimony
developed during the MDL to form their specific opinions in this case. Therefore, Bard is not
prejudiced if Dr. Blackman and Dr. LaDisa testify consistently with those MDL general
causation opinions. At the MDL, Bard had an opportunity to depose and challenge the general
MDL experts that Dr. Blackman and Dr. LaDisa are allegedly relying on. Indeed, that process
led to the exclusion of part of Dr. Hurst’s testimony. While Bard suggests that Lampton is
seeking a “second-bite of the apple” by using Dr. Blackman and Dr. LaDisa to incorporate
general causation testimony into their specific causation analysis, Bard fails to demonstrate
anything that Lampton gains by a “second-bite at the apple,” much less some prejudice Bard
would suffer that would justify the painstaking process of drawing a line between specific and
general causation testimony, a line which is inherently diffuse and will likely evolve as the case
unfolds during a jury trial.
In addition, Bard has not demonstrated how the MDL process will be undermined by
permitting Dr. Blackman and Dr. LaDisa to directly incorporate into their opinions the general
MDL discovery. So long as Lampton’s specific causation experts are not contradicting the
material developed during general discovery or the MDL rulings, the MDL process has
functioned as expected. There is no “second-bite of the apple” in terms of the substance of the
MDL discovery. However, requiring the actual MDL experts to provide all the general expert
testimony at trial, as opposed to a specific causation expert incorporating and relying on the
general MDL discovery, is likely to make the jury trial process more cumbersome, without
providing any added protection for the MDL process.
Finally, the admissibility of Dr. Blackman’s and Dr. LaDisa’s testimony under the
Federal Rules of Evidence, is a matter appropriately raised in a motion in limine or a Daubert
challenge, not subsumed in a motion that seeks to make a distinction between general and
specific testimony. Therefore, the Court does not resolve here whether Dr. Blackman’s and Dr.
LaDisa’s testimony is irrelevant or otherwise inadmissible; it only finds that the testimony is not
excluded because it may be characterized as “general expert testimony.” Once the Court has had
the opportunity to evaluate these issues within the broader context of the case, the Court may or
may not find that Dr. Blackman’s and Dr. LaDisa’s testimony is wholly or in part admissible.
In its Motions to Strike, Bard requests leave of Court to serve expert reports to rebut any
statements, opinions, and conclusions offered by Dr. Blackman and Dr. LaDisa that are not
struck by the Court. Doc. 52, p. 13; Doc. 54, p. 9. The Court concludes that this is an issue
appropriately addressed in a telephone conference. Therefore, the request is taken under
For the foregoing reasons, Bard’s Motion to Strike the general opinions of Dr. Blackman,
Doc. 51, is granted in part. Dr. Blackman cannot rely on or incorporate in his own opinions, the
portion of the expert testimony of Dr. Hurst which was stricken by the MDL court. Otherwise,
the Motion to Strike, Doc. 51, is denied. Bard’s Motion to Strike Dr. LaDisa’s expert report,
Doc. 53, is denied. The Court has taken under advisement Bard’s request for additional expert
discovery to rebut Dr. Blackman’s and Dr. LaDisa’s testimony, pending a scheduled phone
