  • Environmental Expert Was Allowed to Opine on the Impact of PCBs

    Environmental Expert Was Allowed to Opine on the Impact of PCBs

    The Burlington School District (“BSD” or “Plaintiff”) commenced this action after discovering polychlorinated biphenyls (“PCBs”) at Burlington High School (“BHS”). Defendants Monsanto Co., Solutia, Inc., and Pharmacia LLC (collectively “Monsanto” or “Defendants”) are allegedly successors to the old Monsanto company, which was the primary manufacturer of PCBs in the United States for several decades. BHS was constructed in the 1960s, and testing recently revealed the presence of PCBs in its buildings. The BSD concluded that because of PCB contamination, BHS had to be demolished.

    Defendants filed a motion to exclude all testimony of Plaintiff’s experts Wendy Pearson and Robert A. Wanat.

    Discussion by the Court

    I. Monsanto’s Knowledge

    Defendants first argued that opinions about what Monsanto should have known should be excluded. Their contention is that these witnesses’ testimonies about the environmental impacts of PCBs — based in part on information from Monsanto’s own archives — are “mere pronouncements” based on “subjective or speculative opinions” and would constitute a subjective interpretation “based on nothing more than a review of decades-old documents.”

    Pearson reviewed the state of the science related to PCBs over several decades, beginning in the 1930s. Pearson also explained the chemical nature of PCBs and what was known about their dangers. She did offer opinions about what Monsanto could have done to expand its knowledge. Those opinions are based on studies that were known in the scientific community and, in certain instances, by Monsanto itself.

    As a result, the Court found that Pearson’s testimony is not based on speculation. Nor did it constitute merely subjective narrations. Instead, they appeared to be supported by a substantial documentary record that provided a foundation for their opinions. 

    Wanat’s report is similarly supported. He will testify about chemical evaporation generally, and with respect to PCBs specifically. He will also reference Monsanto’s documents, including patents and technical bulletins.

    II. Standard of Care

    Defendants next argued that Pearson’s and Wanat’s opinions regarding industry standards cannot be admitted because they are not supported by sufficient facts, are not based on any methodology, and constitute improper legal conclusions.

    Pearson intended to testify that Monsanto defined its own standard of care and failed to live up to that standard. Wanat’s report is more limited, citing Monsanto’s adherence to American Conference of Government Hygienists thresholds.

    The Court questioned whether the materials in question establish a standard of care, or whether they instead constitute general statements of corporate responsibility. Regardless of the distinction, the Court found no reason to exclude the testimony of either Pearson or Wanat, insofar as their testimony is based on Monsanto’s own statements about its responsibilities.

    Defendants’ final argument is that testimony about the standard of care consisted of improper legal conclusions and stood in the shoes of the jury.

    Here, Plaintiff submitted that Wanat will use the term “reasonable” in its “ordinary, non-legal sense.” Defendants have not identified an element of a pending cause of action that would render the term “reasonable” an impermissible legal conclusion. Consequently, the Court declined to bar such testimony.

    Held

    The Court denied Defendants’ motion to exclude the expert testimony of Wendy Pearson and Robert Wanat.

    Key Takeaway

    To determine when a question posed to an expert witness calls for an improper legal conclusion, the district court should consider first whether the question tracks the language of the legal principle at issue or of the applicable statute, and second, whether any terms employed have specialized legal meaning.

  • Certain Opinions of Environmental Expert Witness Excluded Because They Amount to Contract Interpretation

    Certain Opinions of Environmental Expert Witness Excluded Because They Amount to Contract Interpretation

    Plaintiffs Box Elder Kids, LLC filed a class action lawsuit against Defendants Anadarko Petroleum Corporation, Anadarko E & P Onshore, LLC, and other associated entities alleging a breach of Surface Owner Agreements (SOAs). These agreements obligated Anadarko, as successor to Union Pacific Land Resources Company, to pay a percentage of the value from oil, gas, and other hydrocarbons extracted from lands in Colorado, Wyoming, and Utah, which were previously owned by Union Pacific, to the Plaintiffs.

    The Plaintiffs owned the surface land where these hydrocarbons were extracted. The complaint sought recovery of these payments, referred to as the “Surface Owner Payment.” Additionally, the Plaintiffs claim unjust enrichment and allege fraud, deceit, and constructive fraud against Anadarko and its affiliates.

    Section 2 of the Shaklee SOA contains the following payment provision, which gives the surface owner a contractual right to cash payments based on the value of oil and gas produced from or allocated to the lands covered by the SOAs:

    [Anadarko] agrees, so long as it is receiving oil and/or gas production from or oil and/or gas royalties upon production from the described premises or allocated thereto under the provisions of a unitization agreement, to pay or cause to be paid to the Landowner in cash the value (which shall never be greater than the amount realized by [Anadarko] from the sale of such production) on the premises of two and one-half percent (2-1/2%) of all the oil and gas and associated liquid hydrocarbons hereafter produced, saved, and marketed therefrom or allocated thereto as aforesaid, . . .

    This breach of contract dispute centers around the meaning of ambiguous terms in Section 2 of the parties’ SOAs. The Court considered Plaintiffs’ motion to generally disqualify Defendants’ expert witness, Jamie Jost, and to prevent her from testifying as to various opinions contained her report.

    Environmental Expert Witness

    Jamie Jost is known for her dedication and passion to the Rocky Mountain Region’s environmental and economic sustainability in legal, land use and oil and gas development matters. She is the founder and managing shareholder of Jost Energy Law, P.C., a 100% female owned and operated firm specializing in natural resources and land use law.

    Discussion by the Court

    According to Jost, “When Anadarko’s predecessors and Plaintiffs’ predecessors entered into the SOAs, the parties stated their intent that the described premises may be used for oil and gas development. Section 2 of the SOAs obligates Anadarko to pay Plaintiffs 2.5% of the value of the oil and gas produced from, or allocated to pursuant to a unitization agreement, the surface owner’s described premises subject to the SOA. The SOAs do not require Anadarko to pay more than 2.5% of the value of the oil and gas allocated to the described premises under a unitization agreement. Oil and gas industry terms, custom, and practice support Anadarko’s payment of 2.5% of the value of the oil and gas allocated to the SOA described premises under a unitization agreement.”

    Plaintiffs asked the Court to exclude Jost’s opinions pertaining to (1) the “reasonable” interpretation of the original contracting parties’ intent; (2) oil and gas industry custom; and (3) what the “correct” interpretation of the contract is.

    Section 2 of the Surface Owner Agreement

    Jost’s opinions asserting what Section 2 of the SOAs obligates Defendants to pay, and by what methodology, pertain to the dispositive issue the trier of fact must decide in this case. The Court held that those opinions, which are effectively tantamount to contract interpretation, are inadmissible and will not be permitted.

    Plaintiffs also objected to any opinions offered by Jost that discuss whether Defendants’ interpretation of Section 2 is supported by oil and gas industry custom. In support, they argued that such evidence is inadmissible parol evidence because, “where one party to the agreement is not familiar with the industry, like the original contracting surface landowners here, evidence of industry custom is not helpful to the trier of fact for determining the parties’ intent.” 

    According to the Court, “there appears to be disputed evidence as to whether the original parties had experience dealing in oil and gas contracts.” Whether evidence of industry standards and customs is relevant cannot be determined until the jury decides this threshold fact question. Until then, Jost will be permitted to opine on whether industry standards and customs support Defendants’ interpretation of Section 2’s ambiguous terms.

    What remained in Plaintiffs’ motion challenging Jost are various arguments pertaining to whether her opinions are supported and consistent with language in the SOAs and their competing interpretation of the relevant parol evidence. The Court concluded, however, that such evidence bears on the weight of such evidence, not its admissibility.

    Held

    In sum, the Court will not altogether exclude Jamie Jost’s opinions regarding the ambiguous provisions of Section 2, but it will exclude those opinions that amount to contract interpretation.

    Key Takeaways:

    Jost’s opinions asserting what Section 2 of the SOAs obligates Defendants to pay, and by what methodology, pertain to the dispositive issue the trier of fact must decide in this case. An opinion is not objectionable just because it embraces an ultimate issue. Nevertheless, an expert witness’s testimony may not usurp the jury’s fact-finding function.

  • Montana Court rules against “fossil fuel–based provisions” in favor of a “clean and healthful environment”

    Montana Court rules against “fossil fuel–based provisions” in favor of a “clean and healthful environment”

    On March 13, 2020, sixteen Montana youth (collectively Plaintiffs or Youth Plaintiffs), then between two and 18 years old, filed a complaint against the State of Montana challenging the constitutionality of the State’s fossil fuel-based state energy system, which they alleged caused and contributed to climate change in violation of their constitutional rights guaranteed under Article II, Section 3; Article II, Section 4; Article II, Section 15; Article II, Section 17; Article IX, Section 1; Article IX, Section 3 of the Montana Constitution; and the Public Trust Doctrine. 

    Specifically, the complaint challenged the constitutionality of certain fossil fuel-based provisions which prohibited the State and its agents from considering the impacts of greenhouse gas (GHG) emissions or climate change in their environmental reviews; and the aggregate acts the State took to implement and perpetuate a fossil fuel-based energy system.

    Youth Plaintiffs asked the Court to acknowledge the [Montana Environmental Policy Act] Limitation’s contribution to the depletion and degradation of Montana’s environment and natural resources.

    Discussion by the Court

    CLIMATE SCIENCE AND PROJECTIONS

    Steven Running provided testimony in the general areas of the climate system, including the energy balance and imbalance, the physics of GHG emissions that are driving climate change, the global carbon cycle, the global hydrologic cycle, how they control this energy imbalance, and then how human caused fossil fuel development is harming Montana’s ecosystems and hydrology while Cathy Whitlock explained how human-caused fossil fuel development and the resulting release of CO2 into the atmosphere are harming Montana’s ecosystems, water supplies, communities, and the Plaintiffs themselves. Whitlock’s testimony included projections for Montana’s future based on continuing or increasing the present rate of GHG emissions.   

    CLIMATE CHANGE HARMS CHILDREN AND SPECIFICALLY THE YOUTH PLAINTIFFS

    Lori Byron provided testimony that climate change and the air pollution associated with it are negatively affecting children in Montana, including Youth Plaintiffs, with a strong likelihood that those impacts Will worsen in the absence of aggressive actions to mitigate climate change. Lise Van Susteren provided testimony on the physiological harms caused by climate change to Montana’s youth, including the Youth Plaintiffs, the psychological harms caused by the MEPA Limitation, and the availability of remedies to alleviate Plaintiffs’ psychological injuries. Michael Durglo brought to the table his extensive experience working with tribal elders and youth on climate related issues. The Court found their testimony informative and credible.

    CLIMATE CHANGE IS ALREADY ADVERSELY AFFECTING MONTANA’S NATURAL ENVIRONMENT

    Dan Fagre helped develop a national climate change research program within the National Park Service, coordinating with other scientists at national parks from Florida to Alaska. He built a research program centered on Glacier Park as a representative mountain ecosystem, engaging faculty and scientists from Montana universities and across the U.S. 

    Jack Stanford has published over 220 scientific papers and books on aquatic ecosystem processes, including influences of human activities. 

    Both Stanford and Fagre were of the opinion that anthropogenic climate change was impacting, degrading, and depleting Montana’s environment and natural resources.

    The Court observed that of the approximately 146 glaciers present in Glacier National Park in 1850, only twenty-six glaciers larger than twenty-five acres remained in 2015. 82% of Glacier Park’s glaciers were gone and there had been a 70% loss of area of all glaciers. Moreover, Montana’s water resources were critically important to Youth Plaintiffs and all Montana citizens and to many people beyond the State’s borders. Anthropogenic climate change was disrupting the natural range of variation in the flow paths of Montana’s river systems. 

    DEFENDANTS’ ACTIONS CONTRIBUTE TO CLIMATE CHANGE AND HARM PLAINTIFFS

    Anne Hedges shed light on pollution-related policy issues in Montana, emphasizing on impacts to air, water, landscapes, and climate from fossil fuels.

    Peter Erickson testified about Montana’s fossil fuel consumption, extraction, and infrastructure, focusing on three categories: (1) extraction of fossil fuels; (2) processing and transportation of fossil fuels; and (3) consumption of fossil fuels by end users. For each of these categories, Erickson quantified the amount of coal, oil, and gas and translated that in units of carbon dioxide (CO2) emissions released from the fuels once they are combusted. Erickson added up all the coal, oil, and gas to determine the emissions associated with the extraction, consumption, and transportation of those fuels. In his opinion, emissions from Montana’s fossil fuel consumption, extraction, and infrastructure were globally significant quantities.

    Defendants offered the testimony of Terry Anderson as an expert economist. Purporting to be based on data from the Energy Information Agency (EIA), Anderson provided extremely limited testimony in response to three questions: (1) the total greenhouse gas emissions for the world; (2) the 2020 greenhouse gas consumption emissions for the state of Montana; and (3) the 2022 greenhouse gas consumption emissions for the state of Montana.

    The Court held that Anderson’s testimony was not well-supported and contained errors.

    Defendants permitted three types of fossil fuel-related activities: (1) extraction of fossil fuels; (2) processing and transportation of fossil fuels; and (3) consumption of fossil fuels by end users.

    Data indicated that in 2019, total annual fossil fuels consumed in Montana led to about 32 million tons of CO2 being released into the Atmosphere.

    THE MEPA LIMITATION PREVENTS FULL REVIEW OF THE TECHNOLOGICALLY AND ECONOMICALLY AVAILABLE ALTERNATIVES TO FOSSIL FUEL ENERGY IN MONTANA

    In this case, Mark Jacobson summarized his research related to Montana and the feasibility of transitioning Montana swiftly from fossil fuels to clean and renewable energy in all sectors by mid-century, where all energy sectors include electricity, transportation, heating/cooling, and industry.

    Data indicated that it was technically and economically feasible for Montana to replace 80% of existing fossil fuel energy by 2030 and 100% by no later than 2050, but as early as 2035.

    Held

    The Court ruled that the MEPA Limitation deprived Plaintiffs of their constitutionally guaranteed rights. It upheld Plaintiff’s fundamental constitutional right to a clean and healthful environment, which includes climate as part of the environmental life-support system.

    Key Takeaways:

    Informative and credible testimony presented by experts helped the Court see that Montana has already warmed significantly more than the global average. The science is clear that there are catastrophic harms to the natural environment of Montana and Plaintiffs and future generations of the State due to anthropogenic climate change.

    In terms of per capita emissions, Montana’s consumption of fossil fuels is disproportionately large and only five states have greater per capita emissions. Montana is a major emitter of [greenhouse gas] emissions in the world in absolute terms, in per person terms, and historically. The current barriers to implementing renewable energy systems are not technical or economic, but social and political. Such barriers primarily result from government policies that slow down and inhibit the transition to renewables, and laws that allow utilization of fossil fuel development and preclude a faster transition to a clean, renewable energy system.

    Court: First Judicial District Court of Montana, Lewis and Clark County
    Date: August 14, 2023
  • Environmental Expert Witness barred from testifying about the Applicability of Asbestos National Emissions Standard for Hazardous Air Pollutants

    Environmental Expert Witness barred from testifying about the Applicability of Asbestos National Emissions Standard for Hazardous Air Pollutants

    This case involved two buildings in downtown Burley, Idaho, located at 1222 and 1226 Overland Avenue which burned in late January 2018 and were subsequently demolished in mid-February 2018. A small portion of the debris from the buildings was hauled away to a local gravel pit which also operated as a landfill. Rising concerns about the possible presence of asbestos in the building debris caused the work to cease. Testing at the demolition site after the buildings were demolished was why the presence of asbestos in some of the demolition debris was allegedly confirmed during a clean up by an EPA contractor some six months later. Therefore, the Government asserted that asbestos was present in the buildings before they were demolished. The charges in this case arose from the demolition and clean up of the buildings, which began on February 17, 2018. The fire that damaged the buildings occurred during the early morning hours of January 29, 2018. The cause of the fire was investigated by state and federal law enforcement. Arson was suspected because of circumstances surrounding the fires, including the discovery of an undetonated pipe bomb at the front door of a restaurant located directly across the street from the burned buildings. The presence of this pipe bomb necessitated the involvement of a bomb squad to render it safe. Various individuals were interviewed during the law enforcement investigation of the cause of the fire including Pilling and his former business partner, Brian Tibbets. Pilling and Tibbets were owners of the restaurant where the pipe bomb was found and both were thought to be owners of the Overland buildings that burned. For his part, Pilling was out of the country on a ski trip at the time of the fire. No one was ever criminally charged with causing the fire or for involvement with the pipe bomb found across the street. Pilling was charged by indictment on December 14, 2022, with seven criminal counts related to the demolition and cleanup of the buildings. The Clean Air Act (CAA) provided for criminal penalties if a person knowingly violated the National Emissions Standard for Hazardous Air Pollutants (“NESHAP”) for asbestos that governed the removal of asbestos as the result of demolition and renovation activities. Pilling was charged with failure to thoroughly inspect 1222 and 1226 Overland for asbestos before the demolition commenced (Count One), failure to notify the EPA ten days prior to the commencement of demolition activity (Count Two), failure to remove asbestos prior to demolition (Count Three), failure to have an on-site representative trained in compliance with asbestos work practices (Count Four), failure to adequately wet the asbestos before it was disposed of (Count Five), discharge of visible emissions to the outside air from asbestos-containing waste material (Count Six), and failure to deposit asbestos and components covered with asbestos as soon as practical in a disposal site authorized to accept asbestos (Count Seven).

    The parties have filed various motions in limine, all of which have been addressed by the Court.

    The Defendant filed a motion in limine seeking to exclude six categories of evidence of which the Government opposed the motion as to four of the following categories: (1) Evidence that arson caused the fire at the buildings located at 1222 and 1226 Overland Avenue in Burley, Idaho, in late January 2018, that the buildings caught fire under suspicious circumstances, that a pipe bomb was discovered, or any inference that Pilling was responsible for any of the foregoing; (2) Evidence of any other crime, wrong, or act” of Pilling, if any, pursuant to F.R.E. 404(b); (3) Evidence that asbestos, which was allegedly found in very limited amounts in the Overland buildings debris, is “deadly,” that it may bring on serious diseases, or that “no level of exposure is considered safe;”  and (4) Unsubstantiated belief or opinion held in the local community that Pilling was an “owner” of the buildings or demolition company.

    The Government also filed two motions in limine in response.
    The first motion sought to limit the scope of the Defendant’s cross-examination of Richard Martinez, a Government witness, while the second motion requested a ruling on the admission of certain expert testimony by John Pavitt.

    Chemistry Expert Witness

    Richard Martinez is a Chemist at the United States Environmental Protection Agency’s (EPA) National Enforcement Investigations Center (NEIC), where his areas of work included inorganic and organic chemical analyses and asbestos identification. Martinez has held this position since 2000. He previously held the position of Physical Science Technician at NEIC from 1994 to 2000. Martinez received his Bachelor of Sciences Degree in Biology from the University of Southern Colorado in 1990.

    Environmental Expert Witness

    John Pavitt is a Clean Air Act Inspector and Case Officer with the United States Environmental Protection Agency (“EPA”) and has held that position since 1993. He earned a Bachelor of Science degree in Environmental Studies from Western Washington University in 1986. He has training with respect to the collection of samples for asbestos analysis, and intimate knowledge of the regulations surrounding asbestos treatment and disposal.

    Discussion by the Court

    Defendant sought to prevent the Government from presenting evidence or suggesting that arson caused a fire in Burley, Idaho, in January 2018; the buildings caught fire under suspicious circumstances; a pipe bomb was discovered nearby; or that Defendant was responsible for it. Defendant argued that it was irrelevant and substantially outweighed by the considerations set forth in Rule 403. The Government responded by contending that it needed to provide a coherent and comprehensible story regarding the commission of the crime as well as context for its other evidence such as statements made by the Defendant during an interview with the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) investigators, but it never intended to present evidence of alleged arson as other-act evidence under Rule 404(b). The Court ruled that the Government could not suggest or offer evidence of arson, discovery of a pipe bomb nearby, suspicious circumstances surrounding the fire, or the Defendant’s involvement in it. However, the Government was permitted to briefly explain the context of the interview with ATF agents without implying any connection to the fire or suspicious circumstances.

    The Defendant also sought to prevent the Government from offering evidence that asbestos is “deadly,” that it may cause serious diseases, and that “no level of exposure is considered safe.” The Government responded that the dangerousness of asbestos was relevant to the Defendant’s motive for not undertaking proper abatement and demolition measures. The Court held that the dangers of asbestos inhalation were not relevant to any element of the charged offenses. And, to the extent, that those dangers may have been indirectly relevant to the Defendant’s alleged motive, that relevance was substantially outweighed by the undue delay and unfair prejudice that would have accompanied the presentation of such evidence.

    The Defendant sought to exclude evidence of any “unsubstantiated belief or opinion” held in the “local community” about his ownership of the buildings or demolition company. He argued that such “speculative” and “uninformed” testimony would be irrelevant and unfairly prejudicial. In response, the Government explained that it would not offer any “unsubstantiated” beliefs or opinions of community members, but it did intend to introduce an email from the Defendant’s father to the Defendant which ostensibly revealed the father’s belief that the Defendant owned the buildings.

    At first blush, evidence indicating that the Defendant’s father believed the Defendant to be an owner of the buildings did not appear relevant to whether he actually was an owner. However, the Court observed that both parties indicated that the Defendant’s alleged ownership of the buildings and demolition company would be a key issue at trial. And, to the extent that the direct evidence bearing on ownership was inconclusive, evidence of the father’s belief may have had probative value as circumstantial evidence. Moreover, whatever prejudice that evidence may have had against the Defendant would not have been unfair considering the defense counsel would have the opportunity to challenge the weight of the evidence.

    Accordingly, the Court agreed to allow the Government to offer evidence indicating that the Defendant’s father believed the Defendant to be the owner of the buildings.

    As for the motions in limine filed by the Government, the Government sought to prevent the Defendant from cross-examining Richard Martinez, who analyzed samples for asbestos content in this case.

    In 2020, Martinez was suspended from work for five days in connection with failures in his duties as a Waste Control Officer at the NEIC. Following a related investigation, the EPA Office of Inspector General (OIG) issued a report (the “OIG Report”) addressing “Staffing Constraints, Safety and Health Concerns” at the NEIC laboratory. And, in June of 2023, the EPA’s Office of Criminal Enforcement, Forensics and Training Professional Integrity and Quality Assurance (PIQA) disclosed a summary of a statement (the “PIQA Statement”) that Martinez made to investigators about his suspension and the matters addressed in the OIG Report. The PIQA Statement primarily focused on waste-handling concerns at the NEIC but included one reference to the NEIC’s “failing asbestos program.”

    According to the Government, anything related to Martinez’s suspension, the OIG Report, and the PIQA Statement were irrelevant and did not implicate Martinez’s character for truthfulness. The Defendant responded by arguing that all three subjects were relevant. Namely, the suspension bore on Martinez’s expert qualifications and reliability, and the OIG Report and PIQA Statement reflected the “state of affairs at the NEIC at the time of its involvement in this case.”

    The Court held that Martinez’s suspension arguably bore on the reliability of his expert testimony yet how much weight to give, or not give, the Defendant’s credibility challenges was the jury’s call. The Court noted that Martinez was suspended for his duty-related failures while employed at the NEIC, and that the fact of his suspension did appear to have some tendency to discredit his performance of other job duties, such as testing asbestos content.

    The Court, based on the information now available to it, decided that the OIG Report and PIQA Statement addressed largely—if not entirely—unrelated concerns about the NEIC’s waste-disposal program and that the Report and Statement were irrelevant and off-limits on cross-examination to the extent it was true.

    The Court determined that the OIG Report and PIQA Statement were fair game on cross-examination to the extent they addressed problems (1) at the NEIC testing facility and (2) within the asbestos program.

    The Government also argued that Federal Rules of Evidence 404(a)(1) and 404(b)(1) precluded the Defendant from cross-examining Martinez about his prior suspension. Those rules barred the use of character and other act evidence to prove that a person acted in accordance with a certain character trait on a particular occasion. The Court held that the evidence of the suspension was not being offered to prove the witness’s character, but instead to rebut the Government’s representation of Martinez as a reliable expert whose testimony should be given special weight in light of his experience and expertise.

    Next, the Government sought to introduce Pavitt as a “regulatory expert” in order to “orient the jury as to the ‘requirements of federal regulations and what routine practices’ of the regulated community should be ‘according to the regulations.” Pavitt was hired to (1) Explain that the Clean Air Act regulates the handling and removal of asbestos through NESHAP; (2) Explain “the applicability of the asbestos NESHAP;” (3) Provide and explain the regulatory definitions of various terms, such as “facility component,” “owner or operator of a demolition or renovation activity,” “demolition,” “facility,” “regulated asbestos-containing material,” “friable asbestos material,” and “waste generator;” and (4) Explain “what the work practice standards required.”

    Defendant objected that Pavitt’s proposed testimony consisted of legal conclusions, usurped the Court’s role of instructing the jury, usurped the jury’s role of applying the law to the facts, was unhelpful, and created a risk of confusing the jury.

    The Court held that Pavitt may not opine on the applicability of the asbestos NESHAP, what he believes the work practice standards require, or what he believes owners and operators “should” do to comply with those requirements because opinions about the applicability and meaning of the requirements constitute “legal conclusions.” Moreover, testimony about what owners and operators “should” do to comply with the requirements would also invade the province of the jury to apply the law to the facts. The Court observed that allowing Pavitt to explain when the legal requirements apply and what they require would create a risk of juror confusion, were the witness’s interpretation or description to differ in any respect from the Court’s final instructions.

    Pavitt was, however, allowed to explain technical terms and concepts within the regulations that were likely unfamiliar to the jury and that were pertinent to his testimony considering the asbestos work practice standards contained several technical terms that are likely unfamiliar to the average juror.

    The Court held that Pavitt will be allowed to explain the meaning of technical terms used in the NESHAP to the extent it is necessary for the jury to understand his testimony but will not be allowed to interpret ordinary terms that the average juror is likely to understand.

    Held

    The Defendant’s motion in limine to exclude evidence related to the cause of the fire, evidence related to the dangers of asbestos and beliefs and opinions about ownership of the buildings and demolition company was granted in part and denied in part by the Court. Both the motions in limine filed by the Government to limit cross-examination of EPA Witness and introduce regulatory expert testimony was, once again, granted in part and denied in part by the Court.

    Key Takeaways:

    Key takeaways regarding expert testimony include ensuring its relevance to the case, with a focus on addressing pertinent issues and clarifying complex matters for the jury. Challenges to expert qualifications and reliability are admissible, particularly concerning incidents in their professional history that may impact credibility. Limitations exist on the scope of expert testimony, notably restricting it from offering legal conclusions or assuming the role of the court or jury in interpreting and applying the law. Clarity is essential to avoid confusing the jury, with technical terms explained as needed, while overly complex or confusing testimony risks being excluded. Courts balance the probative value of expert testimony against the risk of prejudice, confusion, or misleading the jury, potentially excluding irrelevant or confusing testimony. Ultimately, the jury decides the weight and credibility of expert testimony, applying the law to the facts presented in the case.
