Tuscumbia City School System v. Pharmacia Corporation

United States District Court, N.D. Alabama, Northwestern Division

February 12, 2015

TUSCUMBIA CITY SCHOOL SYSTEM, on behalf of itself and all others similarly situated, Plaintiff,


C. LYNWOOD SMITH, Jr., District Judge.

This putative class action is before the court on defendant's motion to exclude the expert testimony of Dr. Shaun Crawford, Dr. Lois D. George, Matthew Hageman, Michael Heard, Dr. James Olson, and Robert Thompson.[1] Upon consideration of the briefs and evidentiary submissions, the court concludes that the motion should be granted in part and denied in part.


Analysis of the admissibility of expert testimony must begin with Federal Rule of Evidence 702, which provides that:

A witness who is qualified as an expert by knowledge, skill, experience, training, or education may testify in the form of an opinion or otherwise if:
(a) the expert's scientific, technical, or other specialized knowledge will help the trier of fact to understand the evidence or to determine a fact in issue;
(b) the testimony is based on sufficient facts or data;
(c) the testimony is the product of reliable principles and methods; and
(d) the expert has reliably applied the principles and methods to the facts of the case.

Fed. R. Evid. 702 (2014).[2] The Eleventh Circuit requires district courts to "conduct an exacting analysis of the foundations of the expert opinions to ensure they meet the standards for admissibility under Rule 702." United States v. Abreu, 406 F.3d 1304, 1306 (11th Cir. 2005) (quoting United States v. Frazier, 387 F.3d 1244, 1260 (11th Cir. 2004)) (internal quotation marks and emphasis omitted). The analysis has three parts: that is, district courts are required to assess whether

(1) the expert is qualified to testify competently regarding the matters he intends to address; (2) the methodology by which the expert reaches his conclusions is sufficiently reliable as determined by the sort of inquiry mandated in Daubert [ v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579 (1993)]; and (3) the testimony assists the trier of fact, through the application of scientific, technical, or specialized expertise, to understand the evidence or to determine a fact in issue.

United States v. Frazier, 387 F.3d 1244, 1260 (11th Cir. 2004) ( en banc ) (quoting City of Tuscaloosa v. Harcros Chemicals, Inc., 158 F.3d 542, 562 (11th Cir. 1998)) (alteration supplied); see also, e.g., Rink v. Cheminova, Inc., 400 F.3d 1286 (11th Cir. 2005) (same).

[T]he objective of that requirement is to ensure the reliability and relevancy of expert testimony. It is to make certain that an expert, whether basing testimony upon professional studies or personal experience, employs in the courtroom the same level of intellectual rigor that characterizes the practice of an expert in the relevant field.

Kumho Tire Company, Ltd. v. Carmichael, 526 U.S. 137, 152 (1999) (alteration supplied). "The inquiry... is a flexible one, " because "[m]any factors will bear on the inquiry, and... [there is no] definitive checklist or test." Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579, 593-94 (1993) (alterations supplied). Even so, factors that may be relevant for consideration include:

(1) whether the theory or technique "can be (and has been) tested, " (2) "whether the theory or technique has been subjected to peer review and publication, " (3) "in the case of a particular scientific technique, ... the known or potential rate of error, " and (4) whether the theory or technique is generally accepted by the relevant scientific community.

Hendrix ex rel. G.P. v. Evenflo Company, Inc., 609 F.3d 1183, 1194 (11th Cir. 2010) (quoting Daubert, 509 U.S. at 592-94); see also Rink, 400 F.3d at 1292 (discussing the foregoing factors in the context of assessing an expert's particular scientific technique).


Plaintiff contends that the defendant was negligent and wanton (or reckless) in the design, manufacture, and marketing of electric ballasts for fluorescent light fixtures containing "the now-banned toxic chemicals known as Polychlorinated Biphenyls (PCBs')." Plaintiff alleges that failing ballasts release PCBs into classrooms like those maintained by the plaintiff, and that "PCBs could cause systemic toxic injuries" to humans.[3] Plaintiff summarized the testimony it anticipates eliciting from the expert witnesses challenged by defendant as follows:

1. Dr. Shaun Crawford offers his opinion that he properly sampled both the outsides of the failed ballasts [removed from plaintiff's schools] and the oil from the capacitors.
2. Michael Heard and Matthew Hageman offer their opinion that the samples collected by Dr. Crawford show the presence of PCBs both inside and outside the ballasts.
3. Dr. James Olson offers his opinion that if PCBs have leaked from the ballasts, as shown by the other experts, they pose a serious health risk to anyone in Plaintiff's schools.
4. Robert Thompson provides for the Court a method of calculating damages both in Plaintiff's schools and throughout the class.
5. Dr. Lois George offers her opinion that fluorescent light ballasts can fail at any time and release PCBs into the environment through fire or leakage.

Doc. no. 69 (Plaintiff's Response to Defendant's Motion to Exclude), at ECF 2 (alteration supplied).[4] Plaintiff contends that each of the referenced opinions "is the product of reliable methodology, and each is offered by an individual who is supremely qualified in his or her field."[5]

A. Dr. Shaun Crawford, Matthew Hageman, and Michael Heard

Dr. Shaun Crawford's testimony is offered solely to show that he properly sampled the exterior of four ballasts removed from fluorescent light fixtures in plaintiff's schools, as well as the oil he found in the capacitors of those ballasts.[6] Plaintiff does not intend for Crawford to testify about an analysis of his samples. Instead, plaintiff intends to offer the testimony of Matthew Hageman and Michael Heard for that purpose.[7] It logically follows, therefore, that if the testimony of Hageman and Heard is not admissible, as defendant contends, Crawford's testimony will not be relevant or admissible either. Accordingly, the court must first address the admissibility of the testimony of Hageman and Heard.

Matthew Hageman and Michael Heard, who are employees of Sutherland Environmental Company ("Sutherland"), conducted laboratory testing of the oil and wipe samples collected by Dr. Shaun Crawford.[8] Plaintiff intends to use their testimony to show "the presence of PCBs both inside and outside the ballasts" sampled by Dr. Crawford.[9]

Defendant contends that the testimony of both analysts is unreliable because they disregarded several quality control protocols mandated by their own laboratory.[10]

Sutherland has implemented six quality control protocols for "every analytical measurement" conducted in its laboratory.[11] Most of those protocols are mandated by the United States government's Environmental Protection Agency ("EPA") for PCB testing.[12] Sutherland's first protocol states:

Every sample is spiked with certified surrogate compounds. The surrogates are chemically similar to the target analytes and indicate the extraction/analysis efficiency of each sample. The surrogate recoveries should not exceed three standard deviations (3 Sigma) from the average or exceed EPA method guidelines. If the surrogate recovery is outside the limit, then the sample is repeated.

Doc. no. 64-17 (Sutherland Quality Control Protocols), at 2. Neither Hageman nor Heard followed that protocol.[13]

The second protocol states that a "matrix spike is used to assess the accuracy of the analytical method for a given sample matrix.... The data is acceptable if the results fall within the Upper Control Limit (UCL) and the Lower Control Limit (LCL) of the [quality control chart] for each parameter and matrix."[14] Neither Hageman nor Heard followed that protocol.[15]

The third protocol calls for a "duplicate sample, " which "is used to assess the precision of the analytical method for a given matrix. A duplicate is assayed every 20 samples and must agree within the range set out in the EPA method."[16] Neither Hageman nor Heard followed that protocol.[17]

The fourth protocol states:

Stewhart Quality Control Charts for precision and accuracy have been developed and are used to ensure reliability in accordance with EPA methods.... The Upper Control Limit (UCL) and Upper Warning Limit (UWL) are established statistically and data must be within [these] control ranges to be acceptable.

Doc. no. 64-17 (Sutherland Quality Control Protocols), at 2 (alteration supplied). Neither Hageman nor Heard used a quality control chart when conducting their analysis.[18]

Hageman and Heard offered two explanations for not following the quality control protocols described above. The first was that plaintiff requested only "Level I" testing: that is, Sutherland offers four levels of laboratory testing, and "Level IV is the best to look at everything, " but it also is the most expensive of the four levels.[19] Michael Heard testified that he recommended Level IV testing for purposes of litigation, because it provides a higher level of precision and accuracy than Level I.[20] Similarly, Matthew Hageman testified that "[w]hen you're looking at Level I[, ] it's not going to tell you much."[21]

The second reason given by Hageman and Heard for ignoring four of Sutherland's quality control protocols was that they were instructed to do so by John Sutherland, even though Mr. Sutherland did not explain to either analyst how ignoring the protocols would affect the test results.[22]

Plaintiff contends that the test results are "not shaken by any claims concerning Sutherland's failure to follow procedures that called for a higher level of analysis and were simply unnecessary to determine the mere presence of a substance. Sutherland is a respected lab that was only attempting to show the presence or absence of PCBs."[23] Plaintiff further contends that "Sutherland did not mistakenly fail to do some required step in the process of testing the samples. Rather, it chose to provide a cheaper service that tested only for the presence of PCBs."[24]

The Eleventh Circuit has held, however, that a departure from standard procedures "violates a primary purpose of Daubert: to ensure the expert employs in the courtroom the same level of intellectual rigor that characterizes the practice of an expert in the relevant field." Guinn v. AstraZeneca Pharmaceuticals LP, 602 F.3d 1245, 1255 (11th Cir. 2010) (internal quotation marks omitted); see also In re Paoli R. R. Yard PCB Litigation, 35 F.3d 717, 777-78 (11th Cir. 1994) (holding that a district court did not abuse its discretion in excluding expert testimony because the expert "failed to perform many standard quality control techniques" (emphasis in original)). Heard's testimony that he would employ Level IV testing in the context of litigation suggests that an analysis typical of an expert in the relevant field would have been a Level IV analysis.

Plaintiff has failed to demonstrate that the testing conducted by Hageman and Heard - testing that did not include surrogate compound spikes, matrix spikes, duplicate samples, or a quality control matrix - "has been subjected to peer review and publication, " or is "generally accepted by the relevant... community." See Hendrix, 609 F.3d at 1194. When Hageman was asked at his deposition how his "method" of analysis was validated, Hageman responded that he did not "have any documentation on that."[25] Even so, plaintiff argues that "absolute certainty" is not required of expert testimony.[26] Although plaintiff is correct in that regard, the "known or potential rate of error" of the analysts' methods remains an important consideration. See Hendrix, 609 F.3d at 1194. Here, the rate of error cannot effectively be determined because the analysts ignored most of the quality control protocols meant to ascertain the rate of error.[27] Defendant, on the other hand, has provided EPA language, as well as testimony from its own expert witnesses, showing that the protocols ignored by Hageman and Heard are standard analytic procedures for determining the presence or absence of PCBs.[28]

This court concludes that the failure of Hageman and Heard to follow four of Sutherland's six standard quality control protocols - protocols that also are required by the EPA for PCB testing - renders their findings unreliable. That conclusion is supported by Sutherland's own explanation of its quality control protocols:

Quality control practices at Sutherland Environmental are established as part of every analytical measurement to assure reliability of final results. Variables that can affect results are considered, evaluated and controlled. Quality control is the routine procedural checks, by means of certified standards and spikes, that the data will have known precision and accuracy. Environmental Enforcement Agencies require that each laboratory generating data implement procedures to assure that the precision and accuracy are known and documented. Quality assurance at Sutherland Environmental is the overall program monitoring data reliability. All data released must be within the limit set by the quality control program and be defendable on a statistical basis. The objective of the quality assurance program is to reduce errors to tolerable limits and to assure the system is operating within acceptable limits.

Doc. no. 64-17 (Sutherland Quality Control Protocols), at 3. Accordingly, the expert testimony of Matthew Hageman and Michael Heard will be excluded.

Further, and as a result of the exclusion of the testimony of Hageman and Heard, the court finds that the testimony of Dr. Shaun Crawford, offered only for the purpose of demonstrating that his sampling was proper, is not probative of any fact at issue in this case. See Fed.R.Evid. 702(a). Accordingly, the testimony of Dr. Crawford also will be excluded.[29]

B. Dr. James Olson

The Eleventh Circuit addressed expert causation testimony for toxic tort cases in Chapman v. Procter & Gamble Distributing, LLC, 766 F.3d 1296 (11th Cir. 2014), as follows:

For analyzing cases involving alleged toxic substances, we have delineated two categories. McClain v. Metabolife Int'l, Inc., 401 F.3d 1233, 1239 (11th Cir. 2005). The first category consists of "cases in which the medical community generally recognizes the toxicity of the [substance] at issue" to "caus[e] the injury plaintiff alleges." Id.; Hendrix ex rel. G.P. v. Evenflo Co., 609 F.3d 1183, 1196 (11th Cir. 2010). In this category are "toxins like asbestos, which causes asbestosis and mesothelioma; silica, which causes silicosis; and cigarette smoke, which causes cancer." McClain, 401 F.3d at 1239. For judicial economy, federal courts need not consider expert opinions for diagnoses "medical doctors routinely and widely recognize as true, like cigarette smoking causes lung cancer and heart disease, too much alcohol causes cirrhosis of the liver, and... the ingestion of sufficient amounts of arsenic causes death." Id. at 1239 n.5. In cases where the cause and effect or resulting diagnosis has been proved and accepted by the medical community, federal judges "need not undertake an extensive Daubert analysis on the general toxicity question." Id. at 1239.
In contrast, the second category contains cases, where the medical community generally does not recognize the substance in question as being toxic and having caused plaintiff's alleged injury. Id. These cases require a two-part Daubert analysis, comprised of (1) general causation, "whether the [substance] can cause the harm plaintiff alleges, " id., and (2) specific causation, whether experts' methodology determines the substance "caused the plaintiff's specific injury, " Hendrix, 609 F.3d at 1196 (citing McClain, 401 F.3d at 1239). For cases in category two, a district judge "must assess the reliability of the expert's opinion on general, as well as specific, causation." Id. (first emphasis added).

Chapman, 766 F.3d at 1303-04 (alterations in original). In the absence of contrary authority from either the Supreme Court or the Eleventh Circuit, or persuasive authority from other jurisdictions, this court will assume that PCBs fall under the second category.

Plaintiff offers the testimony of Dr. James Olson to show that " if PCBs have leaked from the ballasts, as shown by the other experts, they pose a serious health risk to anyone in Plaintiff's schools."[30] In other words, plaintiff offers Olson's testimony to show general causation. Note well, however, that plaintiff does not allege personal injury in its amended complaint.[31] Instead, plaintiff alleges that it suffered property damages when PCBs, which admittedly are also capable of causing personal injury, contaminated its property. Plaintiff's claim, then, is for economic loss damages, and Dr. Olson's testimony is offered to show that the release of PCBs can cause property damage.[32]

Even so, plaintiff must address the issue of specific causation: that is, whether defendant's "fail[ure] to exercise reasonable care in the design, sale, testing, marketing, promotion, and distribution of PCBs" actually caused plaintiff's property damage.[33] The rub lies in the fact that plaintiff failed to test any of its classrooms for PCB exposure or contamination. Further, the only expert testimony offered by plaintiff that might have demonstrated contamination - i.e., the testimony of Matthew Hageman and Michael Heard to the effect that PCBs were present in the capacitors and on the exterior of two ballasts - is not admissible.[34]

Moreover, neither Dr. Olson's expert report nor his deposition testimony addresses whether the ballasts in plaintiff's schools actually leaked, or whether PCBs actually contaminated plaintiff's property.[35] Instead, his testimony is based upon an assumption that the ballasts leaked PCBs on plaintiff's property. Dr. Olson cannot testify to specific causation and, thus, he fails the "two-part Daubert analysis" required in cases involving toxic substances. Chapman, 766 F.3d at 1303-04. Further, this court concludes that such incomplete expert testimony - testimony that is based upon the assumption of a fact critical to an element of plaintiff's case - is likely to mislead a jury on the issue of causation. See Daubert, 509 U.S. at 595 ("Expert evidence can be both powerful and quite misleading because of the difficulty in evaluating it. Because of this risk, the judge in weighing possible prejudice against probative force under Rule 403... exercises more control over experts than over lay witnesses.") (internal quotation marks omitted); United States v. Frazier, 387 F.3d 1244, 1263 (11th Cir. 2004) ("Simply put, expert testimony may be assigned talismanic significance in the eyes of lay jurors, and, therefore, the district courts must take care to weight the value of such evidence against its potential to mislead or confuse."). Accordingly, the testimony of Dr. James Olson will be excluded.

C. Robert Thompson

None of plaintiff's experts has tested plaintiff's facilities for PCB contamination. Instead, plaintiff asks that defendant be ordered to pay for testing and for the remediation of facilities found to have been contaminated by PCBs.[36] Plaintiff offers the testimony of Robert Thompson to provide the court with a method for calculating the cost of such testing and remediation.[37]

Thompson has little knowledge concerning PCBs or light ballasts.[38] He has never created a PCB remediation plan, nor has he received any training on PCB remediation.[39] He also is unfamiliar with plaintiff's facilities and classrooms.[40] Even so, Thompson created a PCB remediation plan for plaintiff's schools that was based upon a "standard, generic protocol" created by the EPA, and plaintiff attempts to claim the costs listed in that plan as damages.[41]

Thompson's testimony is unreliable. Not only is Thompson unfamiliar with PCB remediation, but the EPA protocol upon which he relies is not the protocol that ultimately will be used in plaintiff's schools, as evidenced by the following colloquy from Thompson's deposition:

Q: You would have to know [what percentage of light fixtures in each of plaintiff's schools contained PCBs] before calculating damages, wouldn't you?
A: No, but whoever wrote the protocol would.
Q: Okay. Who's going to write the protocol here?
A: I can't answer that. I would not be responsible for that.
Q: Has a protocol been written?
A: Not that I am aware of.
Q: Well, if there's no protocol, how can you cost it out?
A: These are standard boilerplate prices for the process involved in removing PCBs. The EPA has written a standard, generic protocol. And these costs or these activities associated with that are based on that - that standard.
Q: We'll get to that. Am I correct that no individual has written a protocol regarding the removal of PCB-containing ballast[s] for [plaintiff]?
A: Not that I'm aware of.

Doc. no. 64-9 (Thompson Deposition), at 47-48 (alterations supplied).

Plaintiff contends that, even though the "steps that must be taken to remediate PCB contamination come from other sources, Mr. Thompson's job is to determine how much they will cost."[42] Those "steps" have not been determined, however, and Mr. Thompson therefore cannot do his "job" reliably. Indeed, Thompson testified that the yet-unwritten protocol would include some aspects of PCB remediation with which he is unfamiliar: e.g., proper containment practices.[43]

The court cannot allow Thompson to testify as to the costs of PCB remediation in plaintiff's schools when a remediation protocol has not been written, and when Thompson is not even qualified to speculate about the possible details of such a PCB-specific protocol.[44] Accordingly, the expert testimony of Robert Thompson will be excluded as unreliable.

D. Dr. Lois D. George

Plaintiff offers the testimony of Dr. Lois D. George to show that "fluorescent light ballasts can fail at any time and release PCBs into the environment through fire or leakage."[45] Defendant contends that Dr. George's testimony is "unsupported speculation, " and that it has no scientific basis.[46] However, Dr. George based her opinion upon a document written by the EPA providing that: "All of the pre-1979 [ballasts] in lighting fixtures that are still in use are now far beyond their typical life expectancy, increasing the risk of leaks, smoking conditions, or even fires, which would pose health and environmental hazards."[47] That document also states that "[ballast] failures are not uncommon."[48] Accordingly, defendant's argument lacks a basis in fact, and is rejected.


In accordance with the foregoing, it is hereby ORDERED that the motion to exclude expert testimony filed by defendant Pharmacia Corporation is GRANTED in part and DENIED in part. The motion is GRANTED as to the testimony of Dr. Shaun Crawford, Matthew Hageman, Michael Heard, Dr. James Olson, and Robert Thompson, and the testimony of those witnesses is EXCLUDED. The motion as to Dr. Lois George is DENIED.
