Back in 2019, the American Bar Association (ABA) called for courts to appoint special masters regularly in MDLs. Its report claimed that multidistrict proceedings in particular could “benefit from specialized expertise,” and that “[e]ffective special masters reduce costs by dealing with issues before they evolve into disputes and by swiftly and efficiently disposing of disputes that do arise.”
The ABA’s resolution thus urged judges to appoint special masters in complex cases at “the outset of litigation” and permit them to do everything from oversee discovery and pretrial litigation to conduct trials based on parties’ consent, allocate settlements, and administer claims. Failing to do so, it cautioned, “[r]egardless of the reason,” “may disserve the goal of securing ‘a just, speedy, and inexpensive determination.’” Neither this reproach nor the ABA’s empirical claims included empirical support, however.
My co-author, Margie Williams, and I set out to investigate. But we didn’t just look into special masters, we considered everyone that judges allocate power or authority to in MDLs: magistrate judges, claims administrators, lien resolution administrators, and even banks. We posted our article, Judicial Adjuncts in Multidistrict Litigation, on SSRN today and the paper will appear in Columbia Law Review this December. But for those of you who’d prefer the quick version, here’s a summary of our findings:
