MEMORANDUM OPINION
In this successor suit to
District of Columbia v. Heller,
I. Background
Very soon after the Supreme Court invalidated D.C.’s handgun ban in
Heller,
the City Council imposed new restrictions on gun ownership, chiefly through a series of registration requirements. Plaintiffs then immediately filed this action, claiming that these new restrictions still violated the Second Amendment and were in excess of the District’s home-rule authority. Judge Ricardo M. Urbina, to whom this case was previously assigned, ultimately granted summary judgment to the District,
see Heller v. District of Columbia,
On April 19, 2013, the District served Plaintiffs with expert disclosures pursuant to Fed.R.Civ.P. 26(a)(2), identifying Mark D. Jones, Cathy L. Lanier, and Joseph J. Vince, Jr. as expert witnesses. See Opp. at 2. Jones is “a former agent for the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives (“ATF”), with more than 30 years[’] experience in law enforcement, *137 who was assigned to the District of Columbia for more than [seven] years and has participated in more than 100 Federal, state, and local law-enforcement arrests involving unlawful firearms possession, illegal firearms trafficking, misuse of firearms, and firearm-related violence.” See Opp. at 2 (citing Mot. to Strike Expert Testimony of Mark D. Jones, Exh. 1 (Expert Report of Mark D. Jones) at 1). He proffers opinions on the importance of the one-gun-per-thirty-day-period limitation, the in-person registration and renewal requirements, the safety and training requirements, and the requirement' to inform law-enforcement officials of the sale, transfer, or loss of ownership of a firearm. See id. Lanier is “the Chief of Police for the Metropolitan Police Department of .the District of Columbia (“MPD”), with over 20 years of law-enforcement experience (all of it in the District) and is responsible for overseeing MPD’s efforts to prevent gun violence, and arrest and prosecute violent criminal offenders.” See Opp. at 2 (citing Mot. to Strike Expert Testimony of Cathy L. Lanier, Exh. 1 (Expert Report of Cathy L. Lanier) at 1). She opines about law-enforcement challenges unique to the District and about the importance of in-person background checks, safety and training requirements, and registration certificates. See id. Vince is “also a former ATF agent with nearly 30 yearsf] experience investigating the illegal trafficking of firearms and the diversion of firearms for illegal purposes.” See Opp. at 2 (citing Mot. to Strike Expert Testimony of Joseph J. Vince, Jr., Exh. 1 (Expert Report of Joseph J. Vince, Jr.) at 1). Vince opines regarding the benefits and burdens of several of the registration requirements, including long-gun registra-r tion, the thirty-day rule, in-person registration and renewal, safety training, and the notification obligation. See id.
Plaintiffs now move in limine to strike the reports and exclude the proposed expert testimony. Although Plaintiffs’ Motions were filed before any of Defendants’ experts could be deposed, the parties have represented to the Court in a conference call on June 27, 2013, that these depositions have now taken place.
II. Analysis
Plaintiffs challenge Defendants’ proposed expert testimony under two similar, but distinct, legal regimes. First, Plaintiffs assert that Defendants’ expert reports fail to comply'with the disclosure requirements of Fed.R.Civ.P. 26(a). Second, they contend that the proposed expert testimony fails to meet the reliability requirements of Fed.R.Evid. 702 and
Daubert v. Merrell Dow Pharm., Inc.,
A. Rule 26(a)
Plaintiffs first argue that Defendants’ proposed expert testimony must be struck because the disclosure statements they.- served for Jones, Lanier, and Vince do not satisfy the requirements of Fed. R.Civ.P. 26(a). Each expert report, in Plaintiffs’ view, “is devoid of ‘facts or data considered by the witness’ in forming his ‘opinions.’ ” See Jones Mot. to Strike at 5 (quoting Fed.R.Civ.P. 26(a)(2)(B)); Lanier Mot. to Strike at 5; Vince Mot. to Strike at 5. Defendants take issue with this characterization, contending that “each of the challenged reports is rife with facts and data.” See Opp. at 6. Defendants have the better of this argument: while the expert reports may be terse, they provide sufficient information to comply with the goals and requirements of Rule 26(a).
Fed.R.Civ.P. 26(a)(2) provides that a “party must disclose to the other parties
*138
the identity of any witness it may use at trial to present evidence under Federal Rule of Evidence 702, 703, or 705.”
Id.
Disclosures must ordinarily be supplemented by a written report, prepared and signed by the witness, including the substance of the opinions the expert plans to offer and the facts and data he relies upon.
Id.
For proposed experts who regularly provide expert testimony or have been specifically retained to do so, the report must also detail the witness’s qualifications, his past history as an expert, and his compensation.
Id.
“The purpose of Rule 26(a)(2) is to prevent unfair surprise at trial and to permit the opposing party to prepare rebuttal reports, to depose the expert in advance of trial, and to prepare for depositions and cross-examinations at trial.”
Minebea Co., Ltd. v. Papst,
Under Rule 37(c)(1), if a party fails to comply with these disclosure requirements, “the party is not allowed to use that ... witness to supply evidence on a motion, at a hearing, or at a trial, unless the failure was substantially justified or is harmless.” Fed.R.Civ.P. 37(c)(1). “In addition to or instead of this sanction,” courts may provide alternative sanctions, including informing the jury of the party’s failure, awarding costs and attorney fees to the prejudiced party, or any of the other sanctions listed in Rule' 37(b)(2)(A)(i-vi). Id.
The reports here do comply with the requirements of Rule 26(a)(2). Each contains a complete list of the expert’s opinions and the “facts and data considered by the witness.”
See
Rule 26(a)(2). For example, the Vince report outlines each of his opinions and provides a comprehensive list of documents he reviewed in reaching such opinions.
See
Vince Report at 2. He goes on to state that “[t]he opinions that I articulate in this report are based on my experience, my review of numerous studies and books, the District of Columbia’s firearms laws and regulations, and discovery materials from this case made available to me. The materials I used to formulate my opinions are listed above.”
See id.
Jones and Lanier make identical claims.
See
Jones, Report at .4; Lanier Report at 2. Each expert further describes — at great length — the experience he or she drew upon in, reaching these opinions.
See
Jones Report at 1-3; Lanier Report at 1-2; Vince Report at 1-2, 8-10. Because all of these experts explain their experience and the knowledge they have accumulated over many years in the field, the reports provide Plaintiffs with precisely the kind of notice envisioned by Rule 26(a) — notice sufficient to “prevent unfair surprise at trial and to permit the opposing party to prepare rebuttal reports, to depose the expert in advance of trial, and to prepare for depositions and cross-examinations at trial.”
Minebea Co.,
Other courts within this jurisdiction have arrived at similar conclusions, rejecting the idea that “an expert report must be sufficiently complete that no deposition of the expert should be needed to prepare to cross examine him,” and denying motions to strike expert testimony where the expert’s “opinions ... are all in the report and [the opposing party] had the opportunity to depose [the expert] to examine more fully the bases for his opinions.”
Evans v. Washington Metro. Area Transit Auth.,
In this case, Plaintiffs have had an opportunity to depose these experts and examine more fully the bases for their opinions. They will also be able to present opposing lay and expert testimony, as well as have the opportunity, absent summary judgment, to cross-examine Defendants’ experts at trial. Where Defendants have provided adequate notice of the opinions they expect these experts to offer and Plaintiffs have had and continue to have opportunities to challenge these conclusions, the goals of Rule 26(a) are satisfied, and there is no basis for striking the reports and preventing these experts from testifying.
B. Daubert and Rule 702
Plaintiffs next argue that the proposed testimony of Lanier, Jones, and Vince must be excluded under Rule 702 because none of the opinions is “ ‘the product of reliable principles and methods,’ ” nor have the experts “ ‘applied the principles and methods reliably to the facts of the case,’ ” their opinions instead being “ ‘nothing more than the expression of ... personal legislative policy preferences or subjective conclusions.’ ”
See
Lanier Mot. to Strike at 8 (quoting
Estate of Gaither ex rel. Gaither v. District of Columbia,
A district court has “ ‘broad discretion in determining whether to admit or exclude expert testimony.’ ”
United States ex rel. Miller v. Bill Harbert Int’l Constr., Inc.,
A witness who is qualified as an expert by knowledge, skill, experience, training, or education may testify in the form of an opinion or otherwise if:
(a) ' the expert’s scientific, technical, or other specialized knowledge will help the trier of fact to understand the evidence or to determine a fact in issue;
(b) the testimony is based on sufficient facts or data;
(c) the testimony is the product of reliable principles and methods; and
(d) the expert has reliably applied the principles and methods to the facts of the case.
Under Rule 702, trial courts are required to act as gatekeepers who may only admit expert testimony if it is both relevant and reliable.
See Daubert,
Expert testimony is relevant if it will assist the trier of fact to understand
*140
the evidence presented.
See
Fed.R.Evid. 401, 702;
see also Daubert,
“In considering Rule 702 motions, the court assumes only a ‘limited gate-keep[ing] role’ directed at excluding expert testimony that is based upon ‘subjective belief or ‘unsupported speculation.’ ”
Harris v. Koenig,
While the Court’s role is admittedly limited, it cannot “toss the [sic] ‘the decision to receive expert testimony ... off to the jury under a let it all in philosophy.’ ”
Boyar v. Korean Air Lines Co., Ltd.,
“The issue for the Court to determine is whether this- is a case where [the expert’s] assumptions amount to ‘rampant speculation’ and should be excluded, or whether his assumptions merely represent a weak factual basis for his testimony that is appropriately challenged on cross examination.”
Boyar,
Daubert’s
gatekeeping obligations apply to
“all
expert testimony, including testimony based on technical or other specialized knowledge.”
Clay v. Ford Motor Co.,
Each of the experts here uses the same methodology, one that has been approved by courts in a variety of cases involving experts whose experience forms the basis of their opinions. In each case, the expert “observed the relevant evidence” and “applied their specialized knowledge” to the case at hand.
Russell v. Whirlpool Corp.,
In Walker, the Third Circuit approved a trial judge’s admission of testimony from a law-enforcement official who had worked as a narcotics investigator in Harrisburg, Pennsylvania, for some thirty years. Id. The expert’s testimony regarding the geographic origins of cocaine trafficked in Pennsylvania was based upon his experience “regularly participating] in investigations involving the importation of cocaine ... [speaking] with drug traffickers on a daily basis ... working] with a variety of other law enforcement agencies ... [and teaching] courses and seminars on drug trafficking and drug identification.” Id. The Third Circuit held “that [the expert’s] method for reaching these conclusions was reliable,” id., and noted that it “ha[d] previously recognized that law enforcement officials can rely upon their specialized knowledge or experience to offer expert *142 testimony on various aspects of drug trafficking ... [and may] testify in a :Hobbs Act case regarding whether goods had originally been produced in another state.” Id. (citations omitted).
Although the testimony at issue here concerns a different subject from the testimony at issue in
Walker,
it is fundamentally of the same kind: a distinguished law-enforcement official with a long history of specialized experience in a particular area opining on issues within that particular area. Just as
Walker
involved an expert in drug trafficking testifying on the behavior of drug traffickers, the experts here know gun trafficking and gun violence and seek to testify on the behavior of gun owners and users in response to certain gun-control policies. This case is a far cry from one where the opinion evidence “is connected to existing data only by the
ipse dixit
of the expert,” such that “there is simply too great an analytical gap between the data and the opinion proffered.”
Joiner, 522
U.S. at 146,
Indeed, it appears here that the opinion evidence is connected to the - existing facts — the registration requirements and the state of gun violence in the District— by a methodology precisely contemplated by Daubert and Rule 702: each expert’s professional judgment obtained through long experience in -the field. Each of the reports specifically identifies this experience as being the basis..for the opinions proffered, and each provides some justification — in the form of information gained from the expert’s relevant experience — for those opinions. See, e.g., Lanier Report at 4-5 (supporting opinion that “[a]n initial in-person registration and background check are the best means to verify an applicant’s eligibility to possess a firearm” with claim that “the criminal background check performed by MPD, which is based on fingerprints, is more effective than that performed by a gun dealer, which is merely based on a social security number [because identity theft is rampant, and gun dealers are not necessarily well trained in identifying false documents”); Jones Report at 6 (opining that “[i]n my observation a well-regulated firearms registration process increases, the likelihood that law enforcement may successfully trace guns they recover”).
Plaintiffs’ concerns about the conclusions these experts’ experience led them to, and the believability of those conclusions, go to the weight of the testimony and can be appropriately addressed through cross-examination.
See U.S. v. H & R Block, Inc.,
Plaintiffs’ points regarding the D.C. Circuit’s directives on remand similarly go to the weight of the evidence, not its admissibility, and are more appropriately raised on summary judgment or at trial. Plaintiffs are correct in noting that the D.C. Circuit remanded this case “ ‘to develop a more thorough factual record,’ ”
Heller,
Plaintiffs are free to raise these arguments at summary judgment and, if need be, at trial. “Even where an expert’s evidence is ruled admissible under the
Daubert
standards, a district court remains free to decide that the evidence amounts to no more than a mere scintilla ... [and] remains free to grant summary judgment.”
Hirsch v. CSX Transp., Inc.,
Finding the proposed testimony of Jones, Lanier, and Vince sufficiently reliable for purposes of its admission, the Court will allow their reports and their testimony at trial to assist the finder of fact in its evaluation of the evidence.
III. Conclusion
For the foregoing reasons, the Court will deny Plaintiffs’ Motions to Strike the testimony of Cathy L. Lanier, Mark D. Jones, and Joseph J. Vince, Jr. A separate Order consistent with this Opinion shall issue this day.
