  US v. Frazier - 11th Circuit

Decided: 10/15/2004
District Court Decision: Excluded In Part, Admitted
Appellate Court Decision: Affirmed

In Daubert, the Supreme Court suggested that a trial court assessing the reliability of proposed scientific testimony might consider, among others, the following factors: (1) whether the theory or technique underpinning the expert's opinion "can be (or has been) tested"; (2) whether the theory or technique "has been subjected to peer review and publication"; (3) whether, with respect to particular theory or technique, there is a high "known or potential rate of error," and whether there are "standards controlling the technique's operation"; and (4) whether the theory or technique enjoys "general acceptance" within the "relevant scientific community." ... In Daubert v. Merrell Dow Pharms., Inc., 509 U.S. 579, 113 S.Ct. 2786, 125 L.Ed.2d 469 (1993), the Supreme Court "assign[ed] to the trial judge the task of ensuring that an expert's testimony both rests on a reliable foundation and is relevant to the task at hand."

  US v. Bonds - 6th Circuit

Decided: 12/15/1993
District Court Decision: Admitted
Appellate Court Decision: Affirmed

We note that although the findings of the magistrate judge and the district court were based only on the pre-Daubert Frye hearing and the general acceptance test, these findings are relevant to our examination under a Daubert analysis, first because, as the district court noted, neither the defendants nor the Government challenge the magistrate judge's findings regarding the substance of the expert testimony presented at the Frye hearing or his characterization of the testimony, and second, because general acceptance is still one factor the Supreme Court has said can impact on a court's scientific validity determination and the defendants' arguments on appeal focus on these findings and their general acceptance determination. ... The Supreme Court in Daubert v. Merrell Dow Pharmaceuticals, Inc., ___ U.S. ___, 113 S.Ct. 2786, 125 L.Ed.2d 469 (1993), has now rejected Frye's general acceptance test as the exclusive test and has redefined the standard for the admission of expert scientific testimony.[12]

  US v. Crisp - 4th Circuit

Decided: 3/31/2003
District Court Decision: Admitted
Appellate Court Decision: Affirmed

In Daubert, the Court announced five factors that may be used in assessing the relevancy and reliability of expert testimony: 266*266 (1) whether the particular scientific theory "can be (and has been) tested"; (2) whether the theory "has been subjected to peer review and publication"; (3) the "known or potential rate of error"; (4) the "existence and maintenance of standards controlling the technique's operation"; and (5) whether the technique has achieved "general acceptance" in the relevant scientific or expert community. ...

  Newell Rubbermaid, Inc. v. Raymond Corp. - 6th Circuit

Decided: 4/3/2012
District Court Decision: Excluded
Appellate Court Decision: Affirmed

In affirming Brown, this court relied heavily on Dhillon v. Crown Controls Corp., 269 F.3d 865 (7th Cir.2001), where the Seventh Circuit excluded an expert witness's testimony because the expert had not designed forklifts of the model at issue in that case or performed the "crucial" tests on alternative designs that were necessary for considering "product- and manufacturer-specific" issues. ... It concluded that Railsback did not have sufficient training or experience with forklifts to qualify him as an expert witness, that his testimony was not relevant because it involved different models of forklifts than the one at issue in the present case, and that his methods of extrapolating from anecdotal evidence and his failure to test his proposed alternative designs rendered his opinion unreliable.

  US v. Chischilly - 9th Circuit

Decided: 7/25/1994
District Court Decision: Admitted
Appellate Court Decision: Affirmed

Chischilly first challenged the reliability of the Government's DNA extraction and matching procedures on the following grounds: (1) the Government's experts were either drawn from the overly narrow field of forensic scientists, a group predisposed to accept new forensic techniques, or had a career interest in testifying on behalf of the FBI; (2) contaminants could have affected some of the samples relied on by the FBI in its DNA analysis and led to unreliable results; (3) inconsistencies in the gel used by the FBI in the electrophoresis process may affect the mobility of the alleles[7] in the DNA 1153*1153 fragments; (4) ethidium bromide, used by the FBI but not most research laboratories in gel electrophoresis, may retard the migration of DNA fragments through the electrophoretic gel; (5) the presence of additional bands on the autorads[8] interpreted in the RFLP[9] test may have indicated that the DNA samples were degraded; ... While perhaps support for exclusion of Chischilly's DNA test results under the superseded Frye test, with its requirement of general acceptance of a theory in the scientific community, these same statements take on the hue of adverse admissions under Daubert's more liberal admissibility test: evidence of opposing academic camps arrayed in 1156*1156 virtual scholarly equipoise amidst the scientific journals is scarcely an indication of the "minimal support within a community" that would give a trial court cause to view a known technique with skepticism under Daubert's fourth factor.

District Court Decision: Admitted
Appellate Court Decision: Affirmed

Defendants filed a motion in limine requesting the district court exclude ballistics evidence in this case under Daubert v. Merrell Dow Pharmaceuticals, 509 U.S. 579, 113 S.Ct. 2786, 125 L.Ed.2d 469 (1993), and Rule 702. ... During trial and outside the presence of the jury, counsel for Saldana renewed his motion in limine to preclude the testimony of the government's ballistics expert on the grounds that the expert's conclusions concerning the matches in the Wilson and Cerda murders and the Bowser and Prudhomme murders lacked statistical reliability.
