ROANNE L. MANN, UNITED STATES MAGISTRATE JUDGE
Among the various discovery disputes presented to the Court in the State Attorney General Zyprexa cases are those involving the States of Louisiana ("Louisiana" or "LA") and Mississippi ("Mississippi" or "MS") (collectively, the "States"). Specifically, the parties differ as to the adequacy of those States' responses to discovery demands served by defendant Eli Lilly and Company ("Lilly") on May 9, 2008. As described herein, Mississippi and Louisiana are directed to supplement their production of responsive materials and information by August 20, 2008.
A. Timing of Supplemental Responses
As a preliminary matter, the parties disagree as to the date by which the two States must supplement their prior discovery responses. However, since the filing of their respective submissions, this Courtruled that all the plaintiffs in these related actions may have until August 20, 2008, to complete their production of materials and information responsive to Lilly's May 9th discovery demands. See 7/16/08 Case Management Order 2. Consequently, Lilly's challenges to many of the interrogatory responses by Louisiana and Mississippi are premature, in that both States have represented in those responses that their respective investigations are ongoing and that the responses will be supplemented "as necessary." See, e.g., Response to Interrogatory No. 2, Exhibit D to 7/8/08 Letters of Andrew Rogoff in Hood v. Eli Lilly, 07-CV-645 (JBW), and Foti v. Eli Lilly, 05-CV-1455 (JBW) and 05-CV-1549 (JBW).*fn1 The States are required to complete their supplementation by August 20, 2008.
B. Information That Will Be The Subject of Expert Testimony
Lilly challenges the States' objections to a number of interrogatories and/or document demands as calling for information that will be the subject of expert testimony. The States have now offered to supplement their responses by August 20th and, as to some requests, to provide "de-identified, non-individualized information . . . ." 7/11/08 MS Letter at 3; 7/11/08 LA Letter at 3. To the extent that the States have agreed to supplement their responses despite their prior objections, Lilly's challenges are again premature.
With respect to five interrogatory responses common to both States -- i.e., #23, 24, 25, 27 and 29 -- Mississippi and Louisiana adhere to their objections that the information sought is "more properly the subject of expert testimony, including requests for liability profiles and damage models . . . ." 7/11/08 MS Letter at 3; 7/11/08 LA Letter at 4.*fn2 In effect, the States object that Lilly is prematurely seeking responses to contention interrogatories, before the States have had an opportunity to take any discovery and prepare liability profiles and damage models.*fn3
Unlike the Southern District of New York, which has adopted a local rule that defers contention interrogatories until the conclusion of discovery,*fn4 this district has no per se rule prohibiting contention interrogatories in the early stages of discovery. Nevertheless, Eastern District courts have sustained objections to contention interrogatories where the demanding party failed to show that the usefulness of the information sought outweighed the burden imposed in responding early in the litigation. See, e.g., Protex Int'l Corp. v. Vanguard Prods. Group, Inc., No. 05-CV-5355, 2006 WL 3827423, at *2 (E.D.N.Y. Dec. 27, 2006); see also Strauss v. Credit Lyonnais, S.A., 242 F.R.D. 199, 234 (E.D.N.Y. 2007) (collecting cases).
Having reviewed the various discovery demands, and performed the requisite balancing, the Court concludes that some aspects of Lilly's demands are more properly the subject of expert disclosure and that requiring the States to respond at this preliminary phase of fact discovery would be unduly burdensome. For example, Interrogatories #24 and #25 seek a description of the criteria used by the States to determine that a Medicaid recipient developed a medical condition caused by Zyprexa, and to identify medical expenses associated with that condition. Interrogatory #27 demands detailed information regarding the methodology used by the State to compare the medical conditions of Zyprexa users and non-Zyprexa users. See also Interrogatory #29 (seeking "methodology and data for calculating the increase in price" of Zyprexa caused by Lilly's alleged wrongful conduct).
In contrast, several interrogatories (or subparts of interrogatories) seek basic information that, in fairness, should be disclosed promptly, so as to enable Lilly to formulate its defense. For example, Interrogatory #23 asks each State to identify every medical condition that it contends was caused by Zyprexa. Similarly, Interrogatory #27 asks whether, as to each such condition, the State contends that its Zyprexa-using Medicaid recipients had a higher incidence of that condition as compared to another population of individuals. And Interrogatory #29 requires the State to disclose whether it contends that the price of Zyprexa would have been lower but for Lilly's alleged wrongful conduct. While it may be premature at this point to require the States to detail the methodology by which they will prove those assertions, Lilly is entitled to notice as to the nature of the States' allegations against it. Therefore, the States shall promptly provide substantive responses to those portions of the interrogatories.
In their submissions to this Court, the States similarly argue that the following document demands are more properly the subject of expert testimony: MS #3/LA #3; MS #45/LA #47; MS #46/LA #48; MS #48/LA #50; MS #38; MS #47; MS #46/LA #48; MS #48/LA #50; MS #47. See 7/11/08 MS Letter at 3; 7/11/08 LA Letter at 4. Significantly, in response to some of the aforesaid document demands (i.e., MS #3/LA #3, MS #45/LA #47, MS #46, LA #50, MS #38), one or both States failed to assert this particular objection. If not interposed in a State's responses, the objection has been waived.
In any event, a request for pre-existing documents does not implicate the same concerns as a premature contention interrogatory. If, for example, a State representative has developed liability or damages models (MS #48/LA #50), or claims profiles or damages profiles concerning Medicaid recipients (MS #45/LA #47), the State is not entitled to withhold these factual materials on the basis that the same issues ...
