JOHN E. DOWDELL, District Judge.
Before the Court is the defendant's Motion in Limine to Exclude Expert Testimony (Doc. 61). By this Motion,
The government informed defense counsel that Ms. Iski is expected to testify regarding the following: (1) the effects of domestic abuse on the beliefs, behavior, and perception of Pennington; (2) the use of the power and control wheel to describe the complex dynamics of domestic violence; (3) the use of the power and control wheel to demonstrate the various strategies of coercive control that an abusive partner would use against an intimate partner; (4) tactics to impose punishment and encourage fear; and (5) the results of an assessment tool determining the likelihood that defendant committed the alleged crime. (Doc. 61 at 1-2). Defendant does not challenge Ms. Iski's qualifications. Rather, defendant moves to exclude Ms. Iski's proffered testimony on the following grounds: (1) Ms. Iski's testimony regarding Pennington's beliefs, behavior, and perception has no relation to a "fact of consequence" as required by Fed. R. Evid. 401; (2) Ms. Iski's methodology as to the danger assessment fails under Fed. R. Evid. 703 because she did not personally evaluate the victim and her conclusions are based on Pennington's statements to others about a purported pattern of abuse; and (3) Ms. Iski's testimony should be stricken under Fed. R. Evid. 702 because it is neither helpful to the trier of fact nor is it reliable in these circumstances. The Court addresses each of these contentions in turn.
Defendant contends that the effects of domestic abuse on the "beliefs, behavior and perception" of Pennington, one of the issues on which Ms. Iski seeks to provide testimony, are not material to the determination of whether defendant committed second degree murder or voluntary manslaughter under Fed. R. Evid. 402 and should therefore be excluded. (Doc. 61 at 3). Defendant cites no case law in support of this argument.
"[T]he concept of materiality is now embodied within the broader notion of relevance as defined in [401] . . . [and] refers to whether or not that evidence relates to a fact of consequence to the determination of the action." Telum, Inc. v. E.F. Hutton Credit Corp. 859 F.2d 835, 838 (10th Cir. 1988). A fact of consequence describes the "kind of fact to which proof may properly be directed. . . . The fact to be proved may be ultimate, intermediate, or evidentiary; it matters not, so long as it is of consequence in the determination of the action." Fed. R. Evid. 401 (advisory committee notes). "A trial court has broad discretion to determine whether evidence is relevant, and its decision will not be reversed on appeal absent a showing of clear abuse of that discretion." United States v. Bedonie, 913 F.2d 782, 801 (10th Cir. 1990) (quoting Hill v. Bache Halsey Shields, Inc., 790 F.2d 817, 825 (10th Cir. 1986)).
Despite defendant's failure to cite any authority in support of his argument, the Court agrees that Pennington's beliefs, behavior and perception are irrelevant to establish whether defendant committed second degree murder or voluntary manslaughter. Thus, the Court
As stated above, the government expects Ms. Iski to testify regarding the likelihood that defendant committed the alleged crime against Pennington based on a tool called the danger assessment.
Rule 703 of the Federal Rules of Evidence states:
Fed. R. Evid. 703.
Defendant asserts that "it is unlikely that a psychologist or psychiatrist would rely on information provided by third parties . . . in treating or diagnosing a patient." (Doc. 61 at 5). While the Court acknowledges that the danger assessment is a valuable tool, research demonstrates that a properly conducted danger assessment relies on responses given by the victim, not by other witnesses.
Additionally, the Court is particularly troubled by the fact that, though not raised by defendant, the government's representation of Ms. Iski's testimony comes dangerously close to constituting an opinion on an ultimate issue, which is not allowed in criminal cases. Fed. R. Evid. 704(b) prohibits an expert witness in a criminal case from providing an opinion on "whether the defendant did or did not have a mental state or condition that constitutes an element of the crime charged or of a defense," as such "matters are for the trier of fact alone." If Ms. Iski were to testify regarding defendant's likelihood of committing the alleged homicide, there is a risk that her testimony could constitute an opinion as to whether defendant had the mental state to commit either second degree murder or voluntary manslaughter and thus run afoul of Fed. R. Evid. 704(b).
The Court further finds that the introduction of Ms. Iski's testimony would unfairly prejudice defendant under Fed. R. Evid. 403. Rule 403 requires that the Court weigh the probative value of evidence against its potential prejudicial effect. Fed. R. Evid. 403. "Unfair prejudice within its context means an undue tendency to suggest decision on an improper basis . .." Fed. R. Evid. 403 (advisory committee notes). Based on the foregoing discussion regarding the questionable methodology Ms. Iski seeks to employ in conducting the danger assessment, the Court finds that allowing Ms. Iski to perform the danger assessment would have very little probative value. On the other hand, the risk of prejudice, specifically that the jury may fail to see the limitations of Ms. Iski's methodology and take any proffered calculations as conclusive facts, is great.
The Court therefore
Defendant further argues that Ms. Iski's testimony should be excluded because it does not assist the trier of fact nor is it sufficiently reliable as required by Fed. R. Evid. 702 and Daubert.
Pursuant to Federal Rule of Evidence 702, "[e]xpert testimony is admissible only if it is potentially helpful to the jury and `(1) the testimony is based on sufficient facts or data, (2) the testimony is the product of reliable principles and methods, and (3) the [expert] has applied the principles and methods reliably to the facts of the case.'" United States v. Baines, 573 F.3d 979, 985 (10th Cir. 2009) (quoting Fed. R. Evid. 702). "[A] trial court's focus generally should not be the precise conclusions reached by the expert, but on the methodology employed in reaching those conclusions." Bitler v. A.O. Smith Corp, 400 F.3d 1227, 1233 (10th Cir. 2004) (citing Daubert v. Merrell Dow Pharm, Inc., 509 U.S. 579, 592 (1993). Neither Daubert nor the Federal Rules of Evidence require a court to "admit opinion evidence [which contains] too great an analytical gap." Norris v. Baxter Healthcare Corp., 397 F.3d 878, 886 (10th Cir. 2005).
As an initial matter, the Court notes that the government did not file a Response.
Several risk factors have been associated with increased risk of homicides (murders) of women and men in violent relationships. We cannot predict what will happen in your case, but we would like you to be aware of the danger of homicide in situations of abuse and for you to see how many of the risk factors apply to your situation.
Using the calendar, please mark the approximate dates during the past year when you were abused by your partner or ex partner. Write on that date how bad the incident was according to the following scale:
