Appeal from the United States District Court
for the Northern District of Alabama
_________________________
(May 20, 2010)
Before DUBINA, Chief Judge, CARNES and MARCUS, Circuit Judges.
PER CURIAM:
Appellant Cathie Weller filed this action in the district court, asserting
claims under the Federal Tort Claims Act, 28 U.S.C. § 1346(b)(1) and §§ 2671-
2680. Both parties moved for summary judgment. Appellee United States of
America moved for summary judgment on two grounds. The first ground–that
Appellant’s claims were time-barred because she did not file a claim with the
appropriate federal agency within two years of her decedent’s death–was rejected
by the district court. However, the district court granted summary judgment in
favor of Appellee on its second asserted ground. Specifically, the district court
found that the testimony of plaintiff’s experts on the issue of causation was
unreliable and, therefore, inadmissible under Federal Rule of Evidence 702 and
Daubert v. Merell Dow Pharmaceuticals, Inc., 509 U.S. 579 (1993). Without the
testimony of those witnesses, there was no evidence of causation and, accordingly,
the district court concluded that summary judgment in favor of the government
was appropriate.
“We review a district court’s decision to exclude an expert’s testimony
under an abuse of discretion standard.” Rink v. Cheminova, Inc., 400 F.3d 1286,
1291 (11th Cir. 2005) (citing Kumho Tire Co. v. Carmichael, 526 U.S. 137, 152
(1999)). “This standard of review requires that we defer to the district court’s
ruling unless it is ‘manifestly erroneous.’” Id. (quoting Quiet Tech. DC-8, Inc. v.
2
Hurel-Dubois UK Ltd., 326 F.3d 1333, 1340 (11th Cir. 2003)). “Because the task
of evaluating the reliability of expert testimony is uniquely entrusted to the district
court under Daubert . . . we give the district court ‘considerable leeway’ in the
execution of its duty.” Id. (quoting Kumho Tire, 526 U.S. at 152) (internal
citations omitted).
Applying this standard to the facts of this case, we conclude that the district
court did not abuse its discretion in excluding the plaintiff’s proffered expert
testimony. As noted by the district court, both of the plaintiff’s experts, Dr.
Edward Taylor and Dr. Alan Moshell, claim to have utilized what is referred to as
the “differential diagnosis” methodology in reaching their opinions as to causation.
However, as is required in applying that methodology, there is no indication that
either expert compiled a “comprehensive list” of potential causes of the decedent’s
illness or explained why potential alternative causes were ruled out. Both experts
admit in their respective depositions that they failed to rule out the potential role of
other drugs that the decedent was taking in causing his fatal illness.
The district court found that, based on these failures, the experts failed to
apply the differential diagnosis methodology reliably in their respective
evaluations. The district court further found that, because of these failures, the
experts’ testimonies would not assist the trier of fact. For these reasons, the district
3
court concluded that the testimony of both experts should be excluded under Rule
702 and Daubert. The district court did not abuse its discretion in so concluding.
Finally, the district court was correct that, without the testimony of these two
experts, the plaintiff had no evidence as to causation. Accordingly, summary
judgment in favor of the government was proper.
AFFIRMED.
