The U.S. Supreme Court's 2008 decision in Stoneridge Investment Partners, LLC v. Scientific-Atlantic, Inc. illustrated a reformulation of the private-attorney-general model for enforcing federal laws. This case, which rejected another attempt to expand scheme liability in private securities actions to create a new class of defendants, recognized the possible harms from private enforcement. At the same time, it described alternative methods of deterring bad behavior – namely, state and government enforcement. Stoneridge thus follows a pattern of recent securities and antitrust Supreme Court cases that have scaled back on the private attorney general method of enforcement in favor of a more nuanced approach that limits the expansion of private litigation where the harms could exceed its benefits.
