The Roberts Court and the End of the Entity Theory

This Article traces the shift away from the entity theory. It begins with a discussion of the various academic treatments of the entity model, from its first formulation years ago to the more radical “trust device” theories advanced today. It then looks at the various ways in which implicitly adopting the entity model has affected various rulings in class action litigation. Finally, it discusses how the 9–0 opinions in Taylor v. Sturgell, Bayer Corp. v. Smith, and Standard Fire Insurance Co. v. Knowles (buttressed by Justice Elena Kagan’s dissent in Symczyk v. Genesis Health Co.) have made it clear that the Supreme Court favors the aggregation model over the entity model.
