J.P. STADTMUELLER, District Judge.
In the next few months, summer will slowly approach in Wisconsin and, with it, prime swimming season. Swimming is one of the most popular activities in the Badger State with its countless places for recreational swimming, including Lake Michigan, Wisconsin's 15,000 inland lakes, the state's 44,000 miles of rivers, and even artificial public and private pools. However, for those who opt for the latter location in which to dip their toes in the hot summer months, besides a rainy or unseasonably cold day, one of the most formidable enemies of a successful swim is green algae, a greenish growth that can appear on the floors and walls of a swimming pool or can suspend on the top of the pool, making the water unsuitable for swimming. To ensure a proliferation of algae does not further the "summertime blues," swimming pool owners use "shock," a chemical that is a granular form of highly concentrated chlorine
Like other swimming pool owners, the plaintiff, Traci L. Lemmermann ("Lemmermann"), a resident of Belgium, Wisconsin, was faced with a pool filled with algae and opted to use "shock" to treat her pool. Lemmermann claims that on June 11, 2005, upon mixing "HTH Sock It Vinyl Pool Shock" ("Sock It"), a "shock" produced by one of the defendants, Arch Chemicals Inc. ("Arch Chemicals"), with a gallon of water, the solution exploded, causing her respiratory injuries. The defendants dispute that the product exploded upon contact with water and contend that, even assuming the product did explode when exposed to water, the explosion did not cause Mrs. Lemmermann's injuries. Ultimately, the defendants argue that the plaintiff is unable to proffer "competent, admissible expert opinion evidence" to support her claim (Def's Mot. ¶ 5), and, accordingly, the court should award summary judgment pursuant to Fed.R.Civ.P. 56 in favor of the defendants on all counts. (Docket # 16). With the benefit of the parties' briefs on the motion for summary judgment and the various motions to exclude expert testimony (Docket # 20, # 22, # 35), the court is prepared to address the motions. The court will begin by briefly discussing the factual issues animating the present dispute, starting with a discussion of Mrs. Lemmermann's health prior to incident that occurred on June 11, 2005.
In the years prior to the June 11, 2005 incident, the undisputed evidence indicates that the plaintiff suffered from asthma and other problems with her breathing. Mrs. Lemmermann's primary care physician, Richard Bunting, M.D. ("Bunting"), who has cared for the plaintiff since June of 1996, repeatedly treated the plaintiff for her affliction, advising her to use steroid inhalers to treat her medical condition.
Mrs. Lemmermann has also battled allergies, seeing allergist Lauren Charous M.D. ("Charous") in October of 1998. The plaintiff's allergies included positive allergic reactions to "cats, dogs, and a variety of pollens." (DPFF ¶ 54). Dr. Charous provided Lemmermann with a trial of "Singulair," another asthma medicine, although Dr. Bunting does not recall Mrs. Lemmermann undergoing such a trial. In 2002, Dr. Charous formally prescribed Singulair for the plaintiff and also provided Mrs. Lemmermann with Nasacor AQ. Nothing in the record indicates that Lemmermann was treated for asthma in any significant way after 2002, but Lemmermann did report that she was using Albuterol to treat her asthma to hospital officials on June 11, 2005.
In the summer of 2004, the plaintiff purchased a one pound bag of Sock It, a pool treatment product, from a Wal-Mart Stores, Inc. ("Wal-Mart") retail store in Saukville, Wisconsin, in order to treat algae in a pool and keep it clean. The product itself includes a label indicating the active ingredients within the product are ninety-nine percent "Sodium Dichloro-s-Triazinetrione Hydrated" ("sodium dichlor" or "dichlor")
On June 11, 2005, taking an action she had done on "multiple occasions" "without incident," (PPFF ¶ 127), Lemmermann mixed the contents of the one pound of product into a plastic pitcher containing water, in order to better dissolve the product.
The emergency department report for Mrs. Lemmermann indicates that she was admitted because of "chemical chlorine" exposure. (Bunting Dep., 79:21-22). It is undisputed that Lemmermann suffered "superficial eye injuries" and had minor symptoms of respiratory irritation immediately after the incident (PPFF ¶ 175), but whether Mrs. Lemmermann suffered more severe injuries remains in dispute. The plaintiff asserts that she was having difficulties breathing immediately after the explosion, was nauseous, and was suffering from headaches. However, the medical report for Mrs. Lemmermann's visit to the emergency room states that the plaintiff denied any shortness of breath, fever, chills, nausea, vomiting, or chest pain. Moreover, when examined, Lemmermann's lungs were "clear and equal, without rales, wheeze or rhonchi." (DPFF ¶ 65). Dr. Bunting, who examined Mrs. Lemmermann on that day, concluded that Lemmermann's complaints regarding shortness of breath and a headache were due to an "acute anxiety reaction and hyperventilation," as opposed to "exposure to chemicals at the time" of the incident, and, accordingly, prescribed an anti-anxiety medicine for his patient. (DPFF ¶¶ 68-69). Lemmermann ultimately stayed at the hospital for two days following the incident. In several follow-up visits, after the June 11, 2005 incident, Dr. Bunting examined the plaintiff, finding the plaintiff's lungs to be "clear." (DPFF ¶ 70, ¶ 73, ¶ 76). Dr. Bunting concluded that Lemmermann's complaints were caused by a "significant anxiety component," as opposed to chemical exposure. (DPFF ¶ 72). Accordingly, Lemmermann's doctor prescribed Nortriptyline, an antidepressant. Finding nothing abnormal with Lemmermann's breathing, on July 12, 2005, Dr. Bunting referred the plaintiff to Dr. Rula al-Saghir ("al-Saghir"), a pulmonologist, telling Lemmermann to see Dr. al-Saghir "if she still thinks [her breathing to be] a problem." (DPFF ¶ 77).
On June 5, 2008, Lemmermann filed a suit in an Ozaukee County circuit court against defendants Wal-Mart and Arch Chemicals, alleging common law negligence and strict liability claims stemming from the plaintiff making a highly concentrated solution of Sock It and water. A little over three months later, the defendants removed the case to this court. (Docket # 1). During discovery, Arch Chemicals disclosed an internal incident report dated August 13, 2003, which indicated that a customer called to complain that his wife had "added some water to a bucket filled with" Sock It, causing the water to fizz. The report further states
After appropriate discovery occurred, the defendants collectively filed for summary judgment pursuant to Fed.R.Civ.P. 56. (Docket # 16). Propelling the motion for summary judgment were separate motions to exclude the expert testimony of two of the plaintiff's designated experts: (1) Mr. Michael D. Schuck, P.E. ("Schuck") (Docket #20); and (2) Dr. al-Saghir (Docket #22). Accordingly, before the court can determine, based on the evidence provided by the plaintiff, whether Lemmermann can survive summary judgment, the court must first determine what evidence the plaintiff may proffer to challenge the motion for summary judgment. As such, this order will first address the defendants' motions to exclude the expert evidence. The court notes that the plaintiff has filed her own motion to exclude the testimony of one of the defendants' expert, Ms. Sonia Oberson ("Oberson"). The court will reserve judgment on this latter motion until the court resolves the summary judgment issue.
Federal Rule of Evidence 702 and Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579, 113 S.Ct. 2786, 125 L.Ed.2d 469 (1993), govern the admission of expert testimony. Rule 702 states:
Accordingly, a district court is obliged to function as a "gatekeeper" regarding expert testimony, which requires making sure the proposed testimony is both relevant and reliable. Daubert, 509 U.S. at 589, 113 S.Ct. 2786. In order to make such an evaluation, the court must analyze the proposed testimony using a three-step analysis. Ervin v. Johnson & Johnson, Inc., 492 F.3d 901, 904 (7th Cir.2007).
First, "the witness must be qualified `as an expert by knowledge, skill experience, training, or education.'" Id. An expert need not have particular academic credentials to be "qualified," but rather "anyone with relevant expertise enabling him [or her] to offer responsible opinion testimony helpful to judge or jury may qualify as an expert witness." Tuf Racing Prods., Inc. v. American Suzuki Motor Corp., 223 F.3d 585, 591 (7th Cir.2000). Ultimately, "whether a witness is qualified as an expert can only be determined by comparing the area in which the witness has superior knowledge, skill, experience, or education with the subject matter of the witness's testimony." Carroll v. Otis Elevator Co., 896 F.2d 210, 212 (7th Cir.1990). In other words, the focus is not on whether the "expert is qualified in general, but whether his or her `qualifications provide a foundation for [him or her] to answer a specific question.'" Gayton v. McCoy, 593 F.3d 610, 617 (7th Cir.2010) (internal citations omitted).
Third, a court must confirm that an expert's testimony is relevant; that is, the testimony must "assist the trier of fact to understand the evidence or to determine a fact in issue." Ervin, 492 F.3d at 904. Relevant evidence is evidence that has "any tendency to make the existence of any fact that is of consequence to the determination of the action more probable or less probable than it would be without the evidence." Daubert, 509 U.S. at 587, 113 S.Ct. 2786 (citing Fed.R.Evid. 401). The proponent of the expert's testimony bears the burden of proof with respect to whether the admissibility requirements are met. See Lewis v. CITGO Petroleum Corp., 561 F.3d 698, 704 (7th Cir.2009). With these legal principles in mind, the court proceeds to examine the proposed testimony of the two witness that are the subject of the Daubert motions.
The plaintiff wishes to introduce Michael D. Schuck to testify with respect to "Arch's negligence in failing to warn . . .
First, the court examines whether Mr. Schuck is qualified to testify on each of the two issues that his testimony concerns. See Gayton, 593 F.3d at 617 ("[W]e must look at each of the conclusions [the expert] draws individually to see if he [or she] has the adequate education, skill, and training to reach them.").
The court initially examines the qualifications of Mr. Schuck to determine whether he has "superior knowledge, skill, experience or education" in an area that matches the issue of whether mixing uncontaminated dichlor with water will cause an explosion, "the subject matter of the witness's testimony." Carroll, 896 F.2d at 212. Mr. Schuck's academic record indicates that he holds a Bachelor of Science in Chemical Engineering from Wayne State University and a Master of Science in Environmental Engineering from the Milwaukee School of Engineering. The witness' primary qualification to opine on whether a chemical is volatile stems from his most recent work experience. From 1991 until 2006, Mr. Schuck worked for the Aldrich Chemical Company ("Aldrich"), a life science and high technology company whose products are used in scientific research institutions. Schuck served as an environmental engineer at Aldrich, being "charged with the duty of evaluating the hazards of chemicals in assisting the design of 25-30 different Material Safety Data Sheets for products containing various chemicals." (PPFF ¶ 160). Additionally, the witness' expert report indicates that he has extensive experience with providing "regulatory compliance, environmental health and safety . . . compliance, environmental program management and engineering services for industrial clients," which includes tracking and compiling information regarding the use, storage and disposal of chemicals for particular environmental management plans. Mr. Schuck has never worked as a toxicologist, is not certified or licensed as a toxicologist, but does claim to have expertise in the area of toxicology because he has "some friends who are industrial hygienists" who he has "asked for their opinion" on the subject with regard to his teaching a "risk assessment class" at the Milwaukee School of Engineering. (Schuck Dep. 37:13-25). Mr. Schuck conceded in sworn testimony that prior to his engagement in this case that he had no experience or knowledge related to dichlor and had no specific experience dealing with pool chemicals.
Here, the court concludes that Mr. Schuck is qualified to relate his opinion on the volatility of Shock It when solely mixed with water. The witness's years of experience in studying and evaluating the hazards posed by various chemicals and monitoring
The cases the defendants cite offer little support on the question of whether Mr. Schuck is qualified to testify about chemical reactions involving dichlor. Kirstein v. Parks Corp., 159 F.3d 1065 (7th Cir.1998), is not a case about an expert's qualifications to testify, but is rather concerned with the "reliability" prong of the Daubert inquiry. Id. at 1067 ("It is true that Dr. Nelson has impressive credentials . . . [b]ut the fact is that he did no testing on these products, either alone or in combination.") Moreover, the cases of Wintz v. Northrop Corp., 110 F.3d 508 (7th Cir. 1997), and Jones v. Lincoln Electric Co., 188 F.3d 709 (7th Cir.1999), are inapposite on the question of expert qualifications. In both cases, the court pondered motions to exclude witnesses who were to testify regarding the effect a particular substance had on human health. In both cases, the experts had a significant knowledge base regarding the particular substance in question.
The plaintiff does not wish for Mr. Schuck to merely opine on the chemical volatility of Sock It when mixed with water, however. In addition, the plaintiff proffers the witness's testimony to provide evidence that Arch Chemicals was negligent in "failing to warn Mrs. Lemmermann about the propensity of Sock It to cause a hazardous explosion when mixed in a small volume of water." (Pl's Resp. Br. 5). Here, the court concludes that Mr. Schuck is not qualified to testify as to whether Arch Chemicals was negligent in failing to warn the plaintiff regarding the explosive nature of the product in question, as he is not an expert in the field of warnings. While Mr. Schuck's education and job experience reflects considerable expertise in environmental engineering and superior knowledge of the field of chemistry, it shows no similar expertise in the area of warnings. See McCullock v. H.B. Fuller Co., 981 F.2d 656, 657 (2d Cir.1992) ("Woolley's training as an electrical and industrial engineer, along with his experience in the safety field, might qualify him to testify as to the need for a ventilation system, but that was not an issue in dispute. The adequacy of the warning labels was at issue, and Woolley is not an expert in that field because he lacks training or experience in . . . the design of warning labels."); see also Early v. Toyota Motor Corp., 277 Fed.Appx. 581, 585-86 (6th Cir.2008) ("Concerning warnings, the district court found that Nogan had not written or reviewed any owner's or repair manuals for any product, had never created a maintenance schedule for an NBR seal, and made no assertion that he was an expert on warnings. For these reasons, the district court was understandably convinced that nothing in Nogan's educational or professional background qualifie[d] him as an expert regarding either design defects or warnings.").
Mr. Schuck's education and past job experience indicate he lacks an expertise in warnings. The best experience the witness has had in the area of warnings is in his work at Aldrich in designing Material Safety Data Sheets for the chemicals produced by that company. However, the majority of the product labels Schuck crafted were not designed for use by the general consuming public, but were rather
"Even if an expert is qualified," a court should not allow an expert to offer an opinion that does not "rely on proper methodologies" and is "therefore speculative." Weir v. Crown Equip. Corp., 217 F.3d 453, 464 (7th Cir.2000). Accordingly, the court must examine the methodologies that the instant witness used in arriving at the conclusion that mixing uncontaminated Sock It in a small volume of water would create a hazardous situation. In making such an examination, the court keeps in mind the list of relevant factors provided by the Daubert case and its progeny discussed earlier in the order in evaluating the reliability of an expert's methods.
Here, the court finds that Mr. Schuck's methodology for determining that Sock It has a propensity to cause a hazardous explosion when mixed with a small amount of water is not scientifically reliable, and, accordingly, the entirety of his testimony is excludable under Daubert. Indeed, referring to the means by which the witness reached his conclusion as a "methodology" may be generous. Mr. Schuck concluded that dichlor mixed with water was dangerous based on his reading of: (1) the Material Safety Data Sheet for Sock It, which stated that if the material became "damp/wet or contaminated" an "explosive condition may exist"; (2) the
Ultimately, Mr. Schuck has provided to the court what any other person reading the data sheets regarding dichlor could have concluded: that dichlor when mixed with water may cause a reaction. The court is left to speculate whether mixing only dichlor and water, as opposed to dichlor, water, and a third substance, will cause a violent reaction, as the witness has only given the court his ultimate conclusion only supported by other ultimate conclusions. The Seventh Circuit has made clear that when an expert offers the court only a "bottom line," and no means by which to adjudge its validity as an opinion in contrast to a differing opinion, the expert has offered "nothing of value to the judicial process." McMahon v. Bunn-O-Matic Corp., 150 F.3d 651 at 658 (7th Cir.1998). ("No engineer would put such an unsupported assertion in a scholarly article . . . Why then should courts pay it any heed?").
Most troubling for the court is not so much what Mr. Schuck used to conclude that dichlor was volatile when mixed with a small amount of water; rather, what troubles the court is what the witness did not do in providing his expert opinion. Mr. Schuck did absolutely no testing on dichlor and what occurs when the substance is mixed with water. Moreover, the expert did not provide the court with any studies which employed such testing, nor can the expert cite to any literature, document, journal article, textbook, or any other study that indicates that mixing dichlor with water can produce a violent reaction.
Mrs. Lemmermann has designated Dr. al-Saghir, a pulmonologist to whom the plaintiff was referred to by her primary care physician, as the only expert testifying on the medical causation issue. Dr. al-Saghir intends to testify that the plaintiff either: (1) became afflicted with Reactive Airways Dysfunction Syndrome ("RADS"), "the development of a persistent asthma-like condition with airway hyperresponsiveness developing in a previously healthy asymptomatic individual within 24 hours of a single exposure to concentrated respiratory irritants," (DPFF ¶ 97); or (2) suffered an "exacerbation of her asthma" (Pl.'s Resp. Br. 5) as a result of exposure to fumes produced when Lemmermann mixed Sock It with water. The defendants do not contest Dr. al-Saghir's qualifications to testify on the medical causation issue: the witness is a "licensed physician and surgeon specializing in pulmonary medicine and critical care medicine," certified by several medical boards. (PPFF ¶¶ 143-145). Instead, the defendants challenge the methodology used by Dr. al-Saghir to arrive at her diagnosis of: (1) RADS; or, in the alternative, (2) exacerbation of preexisting asthma. As a result, the court examines the means by which Dr. al-Saghir reached her conclusions.
After Dr. Bunting referred the plaintiff to the witness, Dr. al-Saghir first saw Mrs. Lemmermann on July 20, 2005. Before meeting with the plaintiff, the witness reviewed some of Mrs. Lemmermann's most recent records, which indicated that the plaintiff's airway was "moderate[ly] obstruct[ed]" and that the plaintiff was being treated with inhaled bronchodialators since the incident. (al-Saghir Dep. Ex. 16). Dr. al-Saghir did not have any conversations with the plaintiff's primary care physician, however. Notably, the witness did not review Mrs. Lemmermann's "older records" regarding her long history of respiratory problems before the examination. (al-Saghir Dep. 73). During her appointment
Moreover, Dr. al-Saghir appears confused about the nature of the June 11, 2005 incident. While the witness understood that the plaintiff was injured when she tried to dilute sodium dichlor with water, during her deposition Dr. al-Saghir "assume[d] chlorine" was released when dichlor decomposed, when in reality nitrogen trichloride, a distinct substance, is released when dichlor decomposes. (al-Saghir Dep. 66-67). Moreover, Dr. al-Saghir made a similar statement in her February 6, 2009 report. (al-Saghir Dep. Ex. 16) ("Her symptoms started after exposure to chlorine.") Nonetheless, the witness argues that "any fumes in high concentration can cause RADS." (al-Saghir Dep. 69). Having said that, Dr. al-Saghir "does not know the minimum concentration of nitrogen trichloride necessary to cause" RADS, (DPFF ¶ 87), and "does not know the concentration of nitrogen trichloride to which Mrs. Lemmermann was exposed." (DPFF ¶ 88). The witness has not made any statement indicating or explaining whether exposure to nitrogen trichloride can exacerbate preexisting asthma.
The court notes that there are two distinct aspects of any testimony from a medical expert on exposure causation: (1) an expert's opinion on diagnosis of the specific ailment; and (2) an expert's opinion on external causation for the specific ailment. Mary Sue Henifin, Howard M. Kipen & Susan R. Poulter, Reference Guide on Medical Testimony, in Reference Manual on Scientific Evidence 472 (2d ed. 2000). Each aspect of the testimony "should generally be assessed separately, since the bases for such opinions are often quite different." Id. Accordingly, the court will examine each basis for the doctor's conclusions in turn.
The court finds striking flaws with Dr. al-Saghir's methodology for diagnosing RADS as the affliction from which Mrs. Lemmermann suffers. Dr. al-Saghir admits, and both parties agree, that the "first diagnostic criterion of RADS is the absence of preexisting disorder, asthma symptomatology or history of asthma in remission, and exclusion of conditions that can simulate asthma." (DPFF ¶ 98). In addition, all of the parties agree that the "fourth criterion for a valid diagnosis of RADS is the onset of asthma symptoms within minutes to hours, and less than 24 hours after the exposure." (DPFF ¶ 191). Moreover, the parties do not dispute that absent the first and fourth criterion, "a diagnosis of RADS would not be permissible." (DPFF ¶ 98, ¶ 101). However, "Dr. al-Saghir has not abandoned her opinion that Mrs. Lemmermann suffers from RADS" (Pl's Resp. Br. 17), despite: (1) Mrs. Lemmermann's obvious history of battling asthma; (2) the fact Mrs. Lemmermann did not complain about shortness of breath on the day of the incident; and (3) all of the medical records from June 11, 2005, indicating that the plaintiff's lungs were clear and free of injury. Given the clear disconnect between Dr. al-Saghir's concessions regarding a proper diagnosis of RADS and the witness' ultimate diagnosis for Mrs. Lemmermann, it appears that Dr. al-Saghir's diagnosis is "mere speculation and therefore inadmissible." Lewis, 561 F.3d at 705;
However, the logical gaps in Dr. al-Saghir's diagnosis are not the exclusive reason for the court excluding the witness' testimony regarding the RADS diagnosis. The court also notes that the means by which the expert arrived at her conclusion was premised on: (1) the faulty information the plaintiff provided to the expert; and (2) by looking at only the most recent medical records of the plaintiff. While initially relying on Mrs. Lemmermann's own word to make a diagnosis may not have been a poor methodology in and of itself, Walker v. Soo Line R.R., 208 F.3d 581, 586 (7th Cir.2000), continuing to rely on that methodology even though Mrs. Lemmermann's claims of not having a previous history of asthma are indisputably false leave the court puzzled as to how Dr. al-Saghir continues to insist that the plaintiff is suffering from RADS.
The expert's alternative diagnosis of Mrs. Lemmermann's condition is that she is suffering from an "exacerbation of preexisting asthma." Dr. al-Saghir never disclosed this diagnosis in her February 6, 2009 report. (al-Saghir Dep. Ex 16). In fact, the only time Dr. al-Saghir even hinted at this diagnosis prior to the plaintiff submitting proposed findings of fact to the court was at the tail end of her sworn deposition. The transcript of the deposition reads as follows in relevant part:
The above excerpt from Dr. al-Saghir's testimony is the only evidence in the record where the expert states any opinion on the issue of whether the plaintiff is suffering from an "exacerbation of preexisting asthma."
A central role of the court when deciding a Daubert motion is to "examine the methodology the expert has used in reaching his [or her] conclusions." Smith v. Ford Motor Co., 215 F.3d 713, 718 (7th Cir.2000). However, the burden is on the expert and the party proffering the expert to "explain the methodologies and principles supporting the opinion." Minix v. Canarecci, 597 F.3d 824, 835 (7th Cir. 2010). Here, the court is left dumbfounded as to why "exacerbation of preexisting asthma" is a proper diagnosis in this case, and the plaintiff has provided nothing for the court to examine regarding the methodology used by Dr. al-Saghir to arrive at her conclusion.
However, even if the court were to accept as reliable Dr. al-Saghir's conclusions that Mrs. Lemmermann suffers from either: (1) RADS; or (2) an exacerbation of her asthma, the court would still have to exclude the witness' testimony, as the expert is primarily testifying to provide causation testimony—that is, she is testifying that Mrs. Lemmermann's afflictions are caused by her exposure to fumes resulting from dissolving Sock It in water—and her testimony on the external causation is not sufficiently reliable. The Federal Judicial Center's Reference Manual on Scientific Evidence provides a basic four step process for how an expert should make an evaluation of external causation:
Mary Sue Henifin, Howard M. Kipen & Susan R. Poulter, Reference Guide on
Id. at 472, 119 S.Ct. 1167. Federal courts, including those within this circuit, have used the framework in the Reference Manual on Scientific Evidence in analyzing the methodology of an expert providing testimony espousing an external cause for a particular medical ailment. See, e.g., Cunningham v. Masterwear, Inc., No. 04-CV-1616, 2007 WL 1164832, at *3-4, 2007 U.S. Dist. LEXIS 29156, at *11-12 (S.D.Ind. Apr. 19, 2007) (Tinder, J.).
Here, the expert has provided the court with little to no explanation for her conclusions that the plaintiff suffers from RADS or an exacerbation of her previous asthma as a result of the incident on June 11, 2005. In fact, the overwhelming bulk of the plaintiff's submissions to the court defend how Dr. al-Saghir arrived at her diagnoses. (Pl's Resp. Br. 15) ("Dr. al-Saghir's diagnosis is the result of her own examination, continued treatment, and testing of Ms. Lemmermann, as well as of Ms. Lemmermann's medical history . . . Among other things, Dr. Al-Saghir's past experience in observing and treating patients with RADS provided her with the necessary background to diagnose Ms. Lemmermann with such condition [sic]."). However, the court is at a loss as to how Dr. al-Saghir concluded that Mrs. Lemmermann's alleged ailments, especially the "exacerbation of her previous asthma," is the product of what occurred on June 11, 2005.
The plaintiff attempts to paint the defendants' objections to Dr. al-Saghir's testimony as a "battle of the experts" and as "one to be decided by the jury as a matter of credibility." However, as discussed above, the motion to exclude Dr. al-Saghir's testimony is not a "battle" in any sense of the word, as Dr. al-Saghir and the plaintiff are not properly "equipped for the fight." The doctor's testimony is conclusory and does not exhibit even the slightest signs of reliability and, accordingly, under Daubert and its progeny, the court must exclude such evidence from the jury's consideration. Kumho Tire Co., 526 U.S. at 152, 119 S.Ct. 1167. The central case cited by the plaintiff in opposition to the motion to exclude Dr. al-Saghir's testimony is Walker, which stated that medical professionals can rely on "self-reported patient histories" and the "opinions of other medical professionals in forming their opinions." Walker, 208 F.3d at 586. However, even accepting the Seventh Circuit's statement as true, Walker is inapplicable with regard to the question of "external causation" testimony, as the Walker court only found that a medical doctor could rely on self-reported patient histories and the statements of medical professionals that were in factual dispute in making a diagnosis. Nothing in Walker speaks to the question of what is a proper methodology with regard to an expert opining on an external cause for a given medical ailment.
Coupled with the motions to exclude the expert testimony of Mr. Schuck and Dr. al-Saghir was a motion for summary judgment. (Docket # 16). Summary judgment is appropriate where the "pleadings, the discovery, and disclosure materials on file, and any affidavits show that there is no genuine issue of material fact and that the moving party is entitled to judgment as a matter of law." Fed.R.Civ.P. 56(c); Wis. Alumni Research Found. v. Xenon Pharms., Inc., 591 F.3d 876, 882 (7th Cir. 2010). A genuine issue of material fact exists when a reasonable jury could find in favor of the nonmoving party. Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 248, 106 S.Ct. 2505, 91 L.Ed.2d 202 (1986). "The initial burden is on the moving party.. . to demonstrate that there is no material question of fact with respect to an essential element of the non-moving party's case." Delta Consulting Group, Inc. v. R. Randle Constr., Inc. 554 F.3d 1133, 1137 (7th Cir.2009) (quoting Cody v. Harris, 409 F.3d 853, 860 (7th Cir.2005)). Once the movant satisfies this initial burden, the burden then shifts to the non-moving party who "may not rest upon the mere allegations or denials of his pleading, but . . . must set forth specific facts showing that there is a genuine issue for trial." Doe v. Cunningham, 30 F.3d 879, 883 (7th Cir. 1994) (quoting Anderson, 477 U.S. at 248, 106 S.Ct. 2505). In ruling on a summary judgment motion, the court must view the evidence plus all inferences reasonably drawn from the evidence in the light most favorable to the non-moving party. TAS Distributing Co., Inc. v. Cummins Engine Co., Inc., 491 F.3d 625, 630 (7th Cir.2007). With these standards in mind, the court looks to the specific allegations made by the plaintiff.
Lemmermann's complaint alleges two claims for relief, both stemming from the lack of a warning on the product the plaintiff used: (1) negligence; and (2) strict liability. The negligence claim alleges that "the act of pre-mixing . . . Sock It in small of amounts of water creates a dangerous condition," that Arch Chemicals had a duty to warn Lemmermann about the danger, and that Arch Chemicals' breach of its duty resulted in Lemmermann's injuries. (Compl. ¶¶ 16-25). In support of the strict liability claim, the plaintiff contends that the product Sock It was "defective and unreasonably dangerous" "due to the lack of proper warnings" regarding the danger created by "pre-mixing Sock It with water." (Compl. ¶¶ 26-33). Moreover, Lemmermann contends that she has sustained "substantial and permanent" personal injuries from the incident. (Compl. ¶ 14).
Under Wisconsin law, while plaintiffs are permitted to bring both strict liability and negligence claims premised upon the inadequacy of a product's warnings, Wisconsin courts have not distinguished between the standards for liability governing each type of claim. Tanner v. Shoupe, 228 Wis.2d 357, 365 n. 3, 596 N.W.2d 805 (Ct.App.1999) ("[W]hen the
In this case, the defendants argue without Mr. Schuck's testimony on liability and without Dr. al-Saghir's testimony regarding causation that the defendants are entitled to judgment as a matter of law on all counts. The court finds that the defendants have satisfied their initial burden in showing that there are no material facts in dispute and that judgment should be entered in its favor, and accordingly looks to the plaintiff to see if there is any evidence supporting her duty to warn or strict liability claims. Celotex Corp. v. Catrett, 477 U.S. 317, 322-23, 106 S.Ct. 2548, 91 L.Ed.2d 265 (1986). The plaintiff raises a number of arguments for why her claims should survive summary judgment, even without the testimony of the two experts.
First, the plaintiff contends that Arch Chemicals' own Material Safety Data Sheet regarding Sock It on its own indicates that the product has a propensity to explode when mixed with water. The court finds the Material Safety Data Sheet for Sock It, at best for the plaintiff, is ambiguous as to whether combining uncontaminated dichlor and water would cause an explosion. The data sheet merely states that if the product becomes "damp/wet or contaminated in a container the formation of nitrogen trichloride gas may occur" (emphasis added). The data sheet alone begs more questions than it resolves
The lack of any evidence supporting the claim of liability alone is reason to grant the defendants' motion for summary judgment. The court also notes, however, that even assuming the defendants had a duty to warn Lemmermann about the dangers of Sock It and the defendants breached their duty to warn, the plaintiff's claim would still fail because of a lack of evidence proving causation. The plaintiff contends that, even if Dr. al-Saghir cannot testify as an expert witness regarding causation, the doctor can still testify in her capacity as a treating physician with respect to what caused Mrs. Lemmermann's injuries. It is beyond question that, while a treating physician can testify with regard to his or her observations of and treatment provided to a patient, the treating physician becomes an "expert witness"—and with that is subject to the requirements of Rule 702 and Daubert—if the treating physician is opining on matters regarding causation. O'Conner v. Commonwealth Edison Co., 13 F.3d 1090, 1105 n. 14 (7th Cir.1994) ("[W]e do not distinguish the treating physician from other experts when the treating physician is offering expert testimony regarding causation"); see also Musser v. Gentiva Health Servs., 356 F.3d 751, 757 n. 2 (7th Cir.2004) ("Thus, a treating doctor (or similarly situated witness) is providing expert testimony if the testimony consists of opinions based on "scientific, technical, or other specialized knowledge" regardless of whether those opinions were formed during the scope of interaction with a party prior to litigation.").
However, even if the plaintiff articulated a claim regarding the inadequacy of the warning regarding the risk posed by contamination, the plaintiff has nothing in terms of evidence to support the claim. Both parties agree that Mrs. Lemmermann never contended that she contaminated the product when mixing it with water. (Pl's Resp. Br. 27; Def's Br. 9, n. 2). As a consequence, there cannot be any causal link between the inadequacy of the warning on the Sock It label regarding contamination and Mrs. Lemmermann's injuries. Moreover, Arch Chemicals' product conspicuously warns that an explosion can occur when the product has been contaminated.
Ultimately, the plaintiff has no evidence to support critical elements of her duty to warn or strict liability claims. The expert testimony proffered by the plaintiff screams of unreliability and cannot survive the Daubert test for expert evidence, let alone the "laugh test." Lemmermann provides no other reasons for why the plaintiff can survive summary judgment, and, as a result, the court is obliged to find that the defendants are entitled to judgment as a matter of law.
The Clerk of the Court is directed to enter judgment accordingly.
