    Court Cannot Conclude that Environmental Science Expert Witness’ Opinions Meet the Rule 702 Standard

    Plaintiff Utah Physicians for a Healthy Environment’s (“UPHE”) alleged a number of Clean Air Act (“CAA”) and Noise Control Act (“NCA”) violations against Defendants, who are motorcycle dealerships and their owner. At summary judgment, UPHE proffered the expert testimony of Dr. Michael St. Denis. In relevant part, St. Denis opined that a “test motorcycle” purchased by UPHE for this litigation was not in compliance with the CAA’s emissions standards. However, during the air-emissions testing, background levels of hydrocarbons exceeded the federal limit authorized for such testing. Both St. Denis and the testing center admitted that the testing would have been invalid for EPA purposes. However, the testing center stated in an email that the testing data could be used for “development/comparison purposes,” though it did not explain why. Defendants moved to exclude St. Denis’ opinion related to the test motorcycle under Rule 702.

    The Court granted this portion of Defendants’ motion to exclude. In particular, the Court found that UPHE had failed to show that St. Denis’s opinion reflected a reliable application of reliable principles and methods under Federal Rule of Evidence 702(d). The Court reasoned that “[b]oth St. Denis and [the testing center] admitted that the test results were invalid for EPA purposes given that the background levels of hydrocarbons exceeded 5 parts per million.” The Court then observed that “UPHE has not attempted to explain how high background levels of hydrocarbons would affect a test result, nor has it explained why the testing would be valid for comparison purposes.”

    UPHE filed a motion for clarification regarding the Court’s order granting Defendants Harley-Davidson of Salt Lake City, LLC, Northern Utah Power Sports, LLC, and Joseph Timmons, Jr.’s (collectively “Defendants”) motion to exclude a portion of an expert opinion offered by Dr. Michael St. Denis.

    Motion for Clarification

    UPHE argued that St. Denis explained both issues in his expert report. After noting that the initial test result had high background levels of hydrocarbons, in paragraph 33 of his report, St. Denis wrote:

    Elevated levels of [hydrocarbons] in the test cell have two results: 1) the concentration of [hydrocarbons] in the exhaust measured by exhaust analyzers and attributed to combustion is under-reported, and 2) the high level of [hydrocarbons] in the background air is subtracted from the level of [hydrocarbons] measured in the exhaust and artificially lowers the calculated level of emission of [hydrocarbons] from the vehicle. For these reasons, the concentration of [hydrocarbons] in the exhaust of the Test Motorcycle was under-reported. In other words, if the Test Motorcycle did not have an exhaust leak its measured [hydrocarbon] emissions would be greater.

    Next, in paragraph 34, he opined that “[e]ven with the exhaust leak, the emissions of [hydrocarbons plus nitrogen oxides] in the first test were 1.49 g/km, far exceeding the vehicle’s certified level of 0.5 g/km, and the federal standard of 0.8 g/km.” UPHE pointed to the former as evidence that St. Denis did explain how high background levels of hydrocarbons would affect a test result, and to the latter as evidence that St. Denis explained why the tests were valid for comparison purposes.

    Although Defendants attached St. Denis’ expert report to their Motion to Exclude, UPHE did not cite the report in its argument, let alone these particular paragraphs. Nor did UPHE respond to several of Defendants’ arguments on why St. Denis’ air emissions opinions are unreliable.

    Discussion by the Court

    Although it is titled a motion for clarification, the Court noted that it more closely resembles a motion for reconsideration, particularly given that UPHE states in its Reply (for the first time) that it relies on Federal Rule of Civil Procedure 54(b).

    Under Federal Rule of Civil Procedure 54(b), an interlocutory decision can be “revised at any time before the entry of a final judgment adjudicating all the claims.” The Court “is not bound by the strict standards for altering or amending a judgment under Federal Rules of Civil Procedure 59(e) and 60(b),” but the basic assessment for reconsideration remains the same. The Court may grant reconsideration based on the availability of new evidence, an intervening change in the controlling law, or the need to correct clear error or prevent manifest injustice. In other words, it is only appropriate in “extraordinary circumstances” when “the Court has misapprehended the facts, a party’s position, or the controlling law.”

    Analysis

    UPHE does not state which ground for reconsideration could apply. Nonetheless, it is clear that there is no new evidence or change in controlling law, nor was there clear error. Therefore, the only potential ground for reconsideration would be to prevent manifest injustice.

    The Court first notes that a motion for reconsideration is improper when used to “revisit issues already addressed or advance arguments that could have been raised in prior briefing.” As such, the Court could deny the motion for failing to cite the pertinent paragraphs of St. Denis’s report or otherwise argue these issues in its briefing. After all, “[p]arties should make all arguments accessible to the Court, ‘rather than ask [the Court] to play archaeologist with the record.’” Yet, it is also true that St. Denis’s report was in the record, was relatively short—spanning just 16 pages—and at least briefly discussed the subject at issue. Moreover, Defendants attached the report as an exhibit to their motion to exclude, and Defendants cannot argue they were unaware of the report’s assertions.

    Accordingly, if it were a simple matter of one missing citation, the Court might be inclined to reconsider its holding. But the deficiency here is more than that. UPHE bears the burden of demonstrating that its proffered expert’s opinions meet the Rule 702 standard. Here, UPHE failed to adequately show that these particular opinions reflect a reliable application of reliable principles and methods.

    UPHE bears the burden to show it is more likely than not that St. Denis’s opinions reflect a reliable application of reliable principles and methods

    Assuming without deciding that (i) the method of subtracting background hydrocarbons from the hydrocarbons measured in the exhaust is reliable generally and (ii) a test with background levels of hydrocarbons exceeding 5 parts per million is not necessarily invalid for comparison purposes, these statements are still not fully responsive to Defendants’ reliability arguments in their Motion to Exclude. For example, Defendants point out that St. Denis initially calculated emissions based on four tests (three of which were included in the average), then updated the chart to reflect eight tests, excluded some of these tests based on incorrect data, and revised total emissions downwards by more than ten percent. Of these eight attempted emissions tests, the average background hydrocarbon concentration varied widely, ranging from 5.46 ppm to 17.89 ppm.

    Further, Defendants argued that the testing was invalid because SGS Environmental Testing Center in Columbus, Indiana (“SGS”) collected data from the motorcycle after it had been driven for about 100 miles, instead of after its break-in period of 4,000 miles used for initial compliance emissions testing. Defendants also argued that the comparison is not reliable because the motorcycle was not in the same condition as it was when it left Defendants’ custody. Specifically, SGS partially disassembled the motorcycle to weld the exhaust system from the inside to fix the exhaust leak and clamped aluminum foil over the muffler and exhaust pipe. SGS itself stated that it “remain[ed] concerned about the modifications and the mileage on the vehicle for what [St. Denis] want[ed] to do with the results.”

    Motions for Reconsideration Are Generally Not Proper to “Advance Arguments that could have been raised in Prior Briefing”

    St. Denis does not address these concerns in his report, and UPHE did not respond to these arguments in its briefing. UPHE bears the burden to show it is more likely than not that St. Denis’s opinions reflect a reliable application of reliable principles and methods. By failing to respond to these arguments, UPHE did not meet that burden. As such, the Court cannot conclude that St. Denis’s excluded opinions are reliable even given the brief discussion in paragraphs 33 and 34 of his report. And as the Court noted earlier, motions for reconsideration are generally not proper to “advance arguments that could have been raised in prior briefing.” In short, the excluded opinions might be reliable, but UPHE, the proponent of this evidence, failed to show that they are.

    Held

    The Court denied UPHE’s motion for clarification.

    Key Takeaway:

    UPHE bears the burden to show it is more likely than not that St. Denis’s opinions reflect a reliable application of reliable principles and methods. By failing to respond to Defendants’ reliability arguments in their motion to exclude, UPHE did not meet that burden. Basically, motions for reconsideration are generally not proper to “advance arguments that could have been raised in prior briefing.” In short, the excluded opinions might be reliable, but UPHE, the proponent of this evidence, failed to show that they are.

  • 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.
