Many subrogation claims involving fire losses rely heavily on expert testimony. Expert testimony is admissible under Federal Rule of Evidence 702 if it is both relevant and reliable. In Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579 (1993), whose standard has been incorporated into Federal Rule of Evidence 702, the Supreme Court instructed federal trial courts to act as a “gatekeeper” of expert testimony, giving them the power to exclude expert testimony that is not supported by sufficient evidence. In Maria Fernanda Elosu and Robert Luis Brace v. Middlefork Ranch Incorporated, Civil Case No. 1:19-cv-00267-DCN, 2021 U.S. Dist. LEXIS 14449 (D. Idaho Jan. 22, 2021) (Brace), the United States District Court for the District of Idaho exercised its gatekeeper role when it granted in part and denied in part the defendant’s motion to exclude expert testimony pursuant to Daubert and Federal Rule of Evidence 702.
Brace, involved a fire at a vacation cabin in McCall, Idaho. The cabin, owned by Maria Elosu (Elosu) and Robert Brace (Brace and collectively with Elosu, Plaintiffs) was part of a homeowner’s association called Middlefork Ranch, Incorporated (MFR). The cabin had a “wrap around” deck with a propane-fired refrigerator on the north side. On the day before the fire, Brace stained the deck using an oil-based stain. That night, Elosu smoked cigarettes on the deck. The next morning, Plaintiffs used rags to clean up excess oil from the deck and an MFR employee changed the propane on the refrigerator and relit the pilot light. At 4:00 p.m., a fire started in or around the cabin while no one was home. The fire was discovered by a group of contractors who testified that the fire was isolated to the east side of the cabin when they first arrived. Importantly, one witness testified that there was no fire and no flames around the propane-fired refrigerator. The fire destroyed the cabin and the contents within.
