Key Insight: In this case, the parties disagreed on the discoverability of communications between Defendants? foreign subsidiaries and divisions and foreign regulators regarding the filters at issue in the case. Following analysis of the effects of the December 1, 2015 amendments on the Federal Rules of Civil Procedure and of the specific facts of the case, the court determined that the at-issue communications were ?only marginally relevant? and was persuaded that ?the burden of [the] foreign discovery would be substantial.? Thus, the court concluded that Defendants were not required to search their foreign entities for communications with foreign regulators. In the course of its discussion of the amendments, the court stated: “Amended Rule 26(b)(1) was adopted pursuant to the Rules Enabling Act, 28 U.S.C. ? 2072 et. seq. That statute provides that ‘[a]ll laws in conflict with such rules shall be of no further force or effect after such rules have taken effect.’ Id., ? 2072(b). Thus, just as a statute could effectively overrule cases applying a former legal standard, the 2015 amendment effectively abrogated cases applying a prior version of Rule 26(b)(1). The test going forward is whether evidence is ‘relevant to any party?s claim or defense,’ not whether it is ‘reasonably calculated to lead to admissible evidence.'”
