Burkhardt, Jill L., United States Magistrate Judge
In this securities class-action litigation, the trial court denied plaintiff’s request to conduct post-class discovery because the additional discovery would be unduly burdensome under Federal Rule of Civil Procedure 26. The court also denied plaintiff’s request to require defendants to run certain emails through the predictive coding process because defendants had already utilized search terms to screen the emails for responsiveness.
The plaintiff-investors brought this class action against defendants alleging violations of securities law. Plaintiffs sought discovery of documents covering a nine-month period after the class period had ended. Plaintiffs argued that this period likely contained relevant evidence of the defendants’ violations. Defendants argued that it had already conducted discovery outside of the alleged class period and that additional discovery would require manual review and be substantially burdensome, outweighing any resulting benefits. In support of their argument defendants demonstrated the production would increase their discovery costs 26 percent, or $390,000.
Plaintiffs contended that these costs should not be considered because defendants could utilize predictive coding and search terms to screen for relevance and privilege at a cost of only $11,279. Without acknowledging which cost estimate was considered, the court held that the “substantial burden of producing documents from this time period outweighs the benefit of the additional discovery.”
Plaintiffs also argued that defendants should be required to run emails, which had already been screened for relevance using search terms, through the predictive coding process. Defendants contended that utilizing predictive coding on the previously screened documents might negatively affect the quality of the predictive coding process. The court agreed with the defendants’ “method of using linear screening with the aid of search terms to identify responsive documents with regard to the emails already reviewed for the three individual defendants.”
