The opinion of the court was delivered by: Seybert, District Judge
On January 21, 2008, Magistrate Judge A. Kathleen Tomlinson issued an order ("January 2008 Order") striking certain portions of an Amended Report and Opinion of Dr. Diop Kamau, an expert witness retained by Plaintiffs. Presently pending are Plaintiffs' objections to the January 2008 Order.
The Court assumes the parties' familiarity with the relevant factual background. Briefly, Plaintiffs retained an expert witness, Dr. Diop Kamau, to opine on whether Suffolk County police officers were engaging in racial profiling of minority motorists. An issue arose regarding eight witnesses who Dr. Kamau interviewed regarding their experiences with the Suffolk County Police Department. After much back and forth on the issue, it was determined that Dr. Kamau could not provide sufficient identifying information concerning the eight witnesses. Accordingly, in lieu of precluding Dr. Kamau's report and opinion in its entirety, Judge Tomlinson directed Plaintiffs to discuss with Dr. Kamau the possibility of amending his opinion to excise the portion of the opinion discussing the eight witnesses and "exclude any proffers based upon consideration of the statements and interviews of those witnesses." (Order dated December 19, 2007.) On January 8, 2008, Plaintiffs' counsel faxed to Judge Tomlinson Dr. Kamau's Amended Report and Opinion, which purportedly excised reference to and reliance upon the eight excluded witnesses.
After carefully reviewing the Amended Report and Opinion, Judge Tomlinson rendered a detailed analysis of the reports to date and found that the restatement of certain of Dr. Kamau's opinions ran counter to her previous rulings regarding consideration of the statements of the eight witnesses. (January 2008 Order 5.) Judge Tomlinson held that, in rendering his opinion, Dr. Kamau was limited to considering incidents involving Christopher Olujobi, Angel Feliciano, Dolores Brown, Ritchie Rivera, Greg Slate, and Dr. Kamau's personal experience in August 2004. Id. Additionally, Judge Tomlinson directed that five of the 21 conclusions proffered by Dr. Kamau in the Amended Report and Opinion be struck as outside the scope of the permissible specific considerations. An appeal of the January 2008 Order followed.
The Court may set aside a Magistrate's order concerning non-dispositive matters only if the order is "clearly erroneous or contrary to law." Fed. R. Civ. P. 72(a). An order is "clearly erroneous only when the reviewing court[, based] on the entire evidence[,] is left with the definite and firm conviction that a mistake has been committed." E.E.O.C. v. First Wireless, Inc., 225 F.R.D. 404, 405 (E.D.N.Y. 2004) (quoting Weiss v. La Suisse, 161 F. Supp. 2d 305, 320-21 (S.D.N.Y. 2001)) (alteration in original). An order is "contrary to law when it fails to apply or misapplies relevant statutes, case law or rules of procedure." First Wireless, 225 F.R.D. at 405. Furthermore, discovery matters are generally considered non-dispositive. See id. "A magistrate judge's resolution of discovery disputes deserves substantial deference and is overruled only if there is an abuse of discretion." Id. (internal quotation marks and citation omitted).
Rule 702 of the Federal Rules of Evidence provides: If scientific, technical or other specialized knowledge will assist the trier of fact to understand the evidence or to determine a fact in issue, a witness qualified as an expert by knowledge, skill, experience, training or education may testify thereto in the form of an opinion or otherwise, if (1) the testimony is based upon sufficient facts or data, (2) the testimony is the product of reliable principles and methods, and (3) the witness has applied the principles and methods reliably to the facts of the case.
Pursuant to Rule 702, district court judges have discretionary authority "to determine [the] reliability [of an expert's testimony] in light of the particular facts and circumstances of the particular case." Highland Capital Mgmt., L.P. v. Schneider, 551 F. Supp. 2d 173, 178 (S.D.N.Y. 2008) (quoting Kumho Tire Company, Ltd. v. Carmichael, 526 U.S. 137, 158, 119 S.Ct. 1167, 143 L.Ed. 2d 238 (1999)) (alteration in original). "The rule incorporates the principles established in Daubert v. Merrell Dow Pharms., Inc., in which the Supreme Court charged trial courts with a gatekeeping role to 'ensure that any and all scientific testimony or evidence admitted is not only relevant, but reliable.'" Great N. Ins. Co. v. Power Cooling, Inc., No. 06-CV-0874, 2007 U.S. Dist. LEXIS 95912, at *13-14 (E.D.N.Y. Dec. 18, 2007) (quoting Daubert, 509 U.S. 579, 589, 113 S.Ct. 2786, 125 L.Ed. 2d 469 (1993)).
In applying Rule 702, the Second Circuit has advised that courts should consider whether (1) the witness is "qualified as an expert" to testify as to a particular matter; (2) the opinion proffered by the expert is based upon reliable data and methodology; and (3) the expert's testimony (as to a particular matter) will "assist the trier of fact." Nimely v. City of New York, 414 F.3d 381, 397 (2d Cir. 2005). "[T]he Supreme Court has also stated that reliability within the meaning of Rule 702 requires a sufficiently rigorous analytical connection between that methodology and the expert's conclusions. Nimely, 414 F.3d at 396 (citing General Elec. Co. v. Joiner, 522 U.S. 136, 146, 118 S.Ct. 512, 139 L.Ed. 2d 508 (1997) ("A court may conclude that there is simply too great an analytical gap between the data and the opinion proffered."). Thus, "when an expert opinion is based on data, a methodology, or studies that are simply inadequate to support the conclusions reached, Daubert and Rule 702 mandate the exclusion of that unreliable opinion testimony." Nimely, 414 F. 3d at 396-97 (quoting Amorgianos v. Amtrak, 303 F.3d 256, 266 (2d Cir. 2002)). Moreover, the burden is on the party seeking to admit the expert testimony to prove its admissibility by a preponderance of the evidence. Daubert, 509 U.S. at 593 n.10.
The issue here centers on the reliability of certain opinions proffered by Dr. Kamau. Dr. Kamau proffered 21 opinions based on his review of, inter alia, Suffolk County Police Department Civil Complaint Procedures, Summons Procedures, Arrest Procedures, and Reporting Police Activities; review of deposition testimony of Plaintiffs and police witnesses; and his own personal experience and investigation of the Suffolk County Police Department in 2004. In accordance with Judge Tomlinson's December 19, 2007 order, Dr. Kamau explicitly states that his "report excludes my consideration of the complaints of eight (8) members of the public regarding racial profiling by Suffolk County police."
