THOMAS FICK ET AL. v. EXXON MOBIL CORPORATION
No. 13-6608
UNITED STATES DISTRICT COURT EASTERN DISTRICT OF LOUISIANA
January 9, 2017
SUSIE MORGAN, UNITED STATES DISTRICT JUDGE
CIVIL ACTION SECTION “E”
ORDER AND REASONS
Before the Court is a motion in limine filed by Defendant, ExxonMobil Corporation, to exclude the testimony of Plaintiff’s proffered aerial photography expert, Glen Hickerson.1 The motion is opposed.2 For the reasons that follow, Defendant’s motion is DENIED.
BACKGROUND
On January 4, 2017, Exxon filed a motion in limine to exclude testimony or other evidence prepared by Glen Hickerson, Plaintiffs’ aerial photography expert.3 Exxon argues “Mr. Hickerson’s expert opinions are inadmissible because he lacks sufficient qualifications in the field of photogrammetry and the methodology he employed to form his opinions is unreliable and/or unsupported.”4
STANDARD OF LAW
The
The party offering the expert opinion must show by a preponderance of the evidence that the expert’s testimony is reliable and relevant.10 The reliability of expert testimony “is determined by assessing whether the reasoning or methodology underlying the testimony is scientifically valid.”11 In Daubert, the Supreme Court enumerated several non-exclusive factors that courts may consider in evaluating the reliability of expert testimony.12 “These factors are (1) whether the expert’s theory can or has been tested, (2) whether the theory has been subject to peer review and publication, (3) the known or potential rate of error of a technique or theory when applied, (4) the existence and
The Supreme Court has cautioned that the reliability analysis must remain flexible. Various Daubert factors “may or may not be pertinent in assessing reliability, depending on the nature of the issue, the expert’s particular expertise, and the subject of his testimony.”14 Thus, “not every Daubert factor will be applicable in every situation . . . and a court has discretion to consider other factors it deems relevant.”15 In sum, the district court is offered broad latitude in making expert testimony determinations.16
As a general rule, questions relating to the bases and sources of an expert’s opinion affect the weight of the evidence rather than its admissibility and should be left for the finder of fact.17 “Vigorous cross-examination, presentation of contrary evidence, and careful instruction on the burden of proof are the traditional and appropriate means of attacking shaky but admissible evidence.”18 The Court is not concerned with whether the opinion is correct, but whether the preponderance of the evidence establishes that the opinion is reliable. “It is the role of the adversarial system, not the court, to highlight weak evidence.”19
DISCUSSION
I. Is Hickerson Qualified to Give Testimony?
Exxon argues Mr. Hickerson should be precluded from testifying about any version of the photograph Bates-numbered LLE_Fick01756 because he lacks the necessary
In response, Plaintiffs argue Mr. Hickerson need not be a licensed photogrammetrist to provide helpful testimony, because “[w]hat is being asked is whether the two-dimensional photograph provided is a reliable source of information, and what information can be gleaned from said photograph.”22 Plaintiffs contend Mr. Hickerson is qualified to provide testimony on the topic of two-dimensional historical photograph interpretation.23
According to Mr. Hickerson’s sworn declaration, he graduated from Radford University with a Bachelor of Science in Geology.24 Thereafter, he worked for the EPA in its Environmental Photographic Interpretation Center (“EPIC“), which was established to “use monoscopic and stereoscopic aerial photographs and imagery to support [the] EPA’s research and regulatory programs.”25 This work included the analysis of “current and historical environmental aerial photographic interpretation and photogrammetry.”26 While at EPIC, Mr. Hickerson was “involved in refining the technique for utilizing aerial photographs to identify lineament and fractures to determine groundwater flow influences.”27 Mr. Hickerson is currently the Vice President of Environmental Research,
The Court finds Mr. Hickerson is qualified to testify as an expert in the field of historical aerial photography interpretation.
II. Is Hickerson’s Methodology Reliable?
Exxon also argues Mr. Hickerson’s methodology is unreliable because he did not use a stereo pair through a stereoscope to reach his conclusions, which Exxon contends is the “standard methodology.”29 Exxon argues “[s]tereoscopic coverage is absolutely necessary for any meaningful interpretation of imagery as well as the ability to obtain reliable measurements from aerial photographs.”30 Exxon further argues Mr. Hickerson’s methodology is unreliable because using a stereo pair requires the use of multiple images, and Mr. Hickerson used only a single image.31 Essentially, Exxon avers, Mr. Hickerson reached his conclusions based on a magnified image of LLE_Fick01756, which requires no scientific expertise and which invites speculation as to what the image depicts.32
In response, Plaintiffs argue Mr. Hickerson’s methodology employs an interpretation of the historical aerial photograph—a methodology relied upon by the American Society for Photogrammetry and Remote Sensing.33 Plaintiffs contend Mr. Hickerson’s opinions were based on an analysis of the ten basic elements of photographic interpretation, an explanation of which can be found in the “Manual of Photographic Interpretation.”34
The Court finds the issues raised by Exxon with respect to the testimony and report offered by Mr. Hickerson go to the weight and not the admissibility of the evidence. Mr. Hickerson’s testimony will not be excluded pursuant to Rule 702 of the Federal Rules of Evidence. Exxon will have the opportunity to cross-examine Mr. Hickerson and present contrary evidence of its own expert, Clifford Mugnier.
CONCLUSION
For the foregoing reasons, Defendant’s motion in limine35 to exclude Plaintiff’s proffered expert, Glen Hickerson, is DENIED.36
