The Trend Toward MDLs in Products Cases

A review of multidistrict litigation (MDL) statistics confirms the increasing percentages of federal cases being consolidated into MDLs. According to the Judicial Panel on Multidistrict Litigation (JPML) website, as of June 2019, 202 MDLs were pending in 46 different federal districts, in 32 different states, before 160 different transferee judges. California boasts the largest number of MDLs, with 30. New York State is close behind with 26. The 141,721 cases included in these MDLs represent more than 50 percent of the federal civil docket. More than 30 percent (or 70 MDLs) of the pending MDLs are products liability cases, a significant increase from 16 percent in 2005. And, of the 70 MDLs, more than 50 are litigations involving pharmaceutical products and/or medical devices. These numbers highlight the increase in the frequency with which products liability cases are being coordinated in MDL proceedings.

The MDL statute enacted in 1968 allows for the transfer of cases “involving one or more common questions of fact … pending in different districts” to “any district for coordinated or consolidated pretrial proceedings.” 28 U.S.C. § 1407(a). After an MDL is established, later-filed cases involving the same questions of fact are seamlessly transferred to the MDL as tagalong cases. The efficiencies seen in MDL proceedings since 1968 have caused the MDL docket to grow dramatically. In the early years, the “caseload was relatively flat—in the late 1970s and throughout the 1980s, the Panel averaged only around 40 [consolidation] motions per year.” Emery G. Lee III et al., “Multidistrict Centralization: An Empirical Examination,” 12 Journal of Empirical Legal Studies,  211, 221 (2015). By the 1990s, the MDL caseload was growing rapidly. Today, the JPML reports that it considers more than 55 motions per year on average, and as of the end of 2018, MDLs accounted for 52 percent of all civil cases pending in federal court.
