Mcclurg v. Mallinckrodt, Inc.

United States District Court, E.D. Missouri, Eastern Division

July 21, 2017

SCOTT D. MCCLURG, et al., Plaintiffs,
v.
MALLINCKRODT, INC.,, Defendants.

          MEMORANDUM AND ORDER

          AUDREY G. FLEISSIG UNITED STATES DISTRICT JUDGE

         This matter is before the Court on Plaintiffs' motion (ECF No. 608) to supplement three of their common-issues expert reports, in order to correct the experts' opinions as to Defendant Cotter Corporation's releases of radiation. Plaintiffs wish to alter the calculations the experts performed because those calculations were imprecise, having been based on mere assumptions about the dryer system used by Cotter to dry the radioactive material at issue. During Defendants' deposition of one of Plaintiffs' experts, Nicholas P. Cheremisinoff, Ph.D., Cotter produced the actual specifications of the dryer system, which Plaintiffs assert will allow their experts to offer precise calculations.[1] For the reasons set forth below, the Court will grant Plaintiffs' motion in part.

         BACKGROUND

         Plaintiffs state that Dr. Cheremisinoff did not have access to the actual specifications of the dryer system either at the time he disclosed his original expert report, in accordance with the Case Management Order (“CMO”), on January 20, 2017, or at the time of his first supplemental report on April 28, 2017.[2] Dr. Cheremisinoff instead relied on “reasonable assumptions” regarding the specifications to perform his calculations regarding releases. Two of Plaintiffs' other common-issues experts, air modeler Camille Sears, and toxicologist James Clark, Ph.D., relied on Dr. Cheremisinoff's calculations to perform their own calculations regarding radiation release and Plaintiffs' exposure thereto. Plaintiffs requested the actual specifications from Cotter in discovery, but Cotter did not produce the specifications until the deposition of Dr. Cheremisinoff. Plaintiffs argue that Cotter was required to disclose the specifications earlier, in response to Plaintiffs' discovery requests. Therefore, Plaintiffs also argue that Cotter should pay the “costs and fees associated with any re-deposition of Plaintiffs' experts.” ECF No. 608 at 7.

         Dr. Cheremisinoff and Sears have already been deposed by Defendants, and Dr. Clark's deposition has been scheduled for July 25, 2017. Dr. Cheremisinoff attests that “the source terms [for his calculations] can be reassembled within a few days to a week using the identical methodology applied to prepare the estimates published in [his original] Jan. 2017 report.” ECF No. 608-2 at 3. Therefore, Plaintiffs state that Dr. Cheremisinoff will be able to issue a revised report in less than two weeks. Plaintiffs do not indicate how long Sears and Dr. Clark will need to revise their reports, but at a July 10, 2017 status conference with the Court, Plaintiffs indicated that these experts, too, would rely on the same methodology they previously used but would simply substitute certain inputs in their respective calculations.

         In opposition to Plaintiffs' motion, Cotter argues that it was not required to produce the specifications earlier because the specifications were obtained by its expert, and under the CMO, Cotter is not required to disclose its experts or the facts or data considered by its experts, until September 15, 2017. Cotter argues that, until its expert is designated as a trial expert, any research the expert has conducted is and was protected work product.[3]

         Although Cotter does not state the precise date on which it obtained copies of the specifications, Cotter contends that its expert did not obtain the specifications until after Dr. Cheremisinoff issued his original expert report on January 20, 2017. Further, Cotter argues that Dr. Cheremisinoff knew the model number of the dryer used by Cotter before he issued his January 20th expert report, and that Dr. Cheremisinoff could have obtained the specifications on his own, by conducting internet research and contacting the manufacturer, as Cotter's expert did.

         Defendant Mallinckrodt, Inc., also opposes Plaintiffs' motion. Mallinckrodt argues that Plaintiffs have already supplemented Dr. Cheremisinoff's expert report once, and should not be able to do so again, in order to incorporate “publicly available” information about the dryer system that Plaintiffs' experts could have located on their own. Mallinckrodt also states that “[a]lthough Plaintiffs' motion represents that Plaintiffs only seek leave to amend the dryer emission source term calculations by Cheremisinoff (which will then also lead to amended reports by Sears and Clark), Mallinckrodt anticipates Plaintiffs will change other admitted mistakes in Cheremisinoff's calculations that were brought to light during deposition.” ECF No. 612 at 4.

         Finally, both Defendants argue that allowing supplementation now would prejudice Defendants because it would delay the litigation further and may require some adjustment to Defendants' experts' reports, which are currently due on September 15, 2017.

         DISCUSSION

         Under Federal Rule of Civil Procedure 26(a)(2)(B), an expert witnesses must provide a written report containing, among other things, “a complete statement of all opinions the witness will express and the basis and reasons for them.” Rule 26(a)(2)(D) requires that such reports be disclosed “at the times and in the sequence that the court orders.” Fed.R.Civ.P. 26(a)(2)(D). This Rule “prevents experts from ‘lying in wait' to express new opinions at the last minute, thereby denying the opposing party the opportunity to depose the expert on the new information or closely examine the expert's new testimony.” Minebea Co. v. Papst, 231 F.R.D. 3, 6 (D.D.C. 2005).

         Rule 26(e)(1) provides that “[a] party who has made a disclosure under Rule 26(a) . . . must supplement or correct its disclosure. . . in a timely manner if the party learns that in some material respect the disclosure or response is incomplete or incorrect, and if the additional or corrective information has not otherwise been made known to the other parties during the discovery process or in writing.” Fed.R.Civ.P. 26(e)(1)(A). For an expert witness, “the party's duty to supplement extends both to information included in the report and to information given during the expert's deposition, ” and “[a]ny additions or changes to this information must be disclosed by the time the party's pretrial disclosures under Rule 26(a)(3) are due.” Fed.R.Civ.P. 26(e)(2).

         “The duty to supplement arises when the expert subsequently learns of information that was previously unknown or unavailable, and the new information renders the earlier report incomplete or inaccurate.Coene v. 3M Co., 303 F.R.D. 32, 42 (W.D.N.Y. 2014) (citations omitted); see also Wilson v. Sundstrand Corp., No. 99 C 6944, 2003 WL 22012673, at *7 (N.D. Ill. Aug. 25, 2003) (holding that a party need not first obtain leave of court to supplement an expert report under Rule 26(e)(1); rather, that rule “imposes an obligation to supplement an expert disclosure ‘if the party learns that in some material respect the information disclosed is incomplete or incorrect'”). However, a supplementation under Rule 26(e) should not be used as an opportunity to disclose “new opinions.” See Coene, 303 F.R.D. at 42 (citing cases).

         In light of Plaintiffs' assertion that the newly-obtained specifications render the previously disclosed expert reports incomplete or inaccurate, the Court believes that Plaintiffs are entitled to correct the reports under Rule 26(e)(1). Whether the specifications were previously unavailable to Plaintiffs is a close question, in light of the fact that Dr. Cheremisinoff had the correct model number and perhaps could have obtained the specifications from the manufacturer on his own, as Cotter's expert ultimately did. But it is likewise a close question whether Cotter should have produced the specifications earlier, given that they were responsive to Plaintiffs' discovery requests. See, e.g., Transamerica Life Ins. Co. v. Lincoln Nat'l Life Ins. Co., 255 F.R.D. 645, 652 (N.D. Iowa 2009) ...
