Much of the antitrust community's attention over the last year has focused on the ongoing shifts at the federal agencies—by way of example, so far this year, our articles have covered the aggressive review of, and in some cases, departure from, the horizontal and vertical Merger Guidelines by the Federal Trade Commission (FTC) and Department of Justice (DOJ); the DOJ's criminal prosecution of no-poach agreements; and federal agencies' withdrawal of Trump-era patent policy, among others. But state antitrust enforcers have been active as well—and, like the federal agencies, they have had mixed results. State attorneys general play a unique role in U.S. antitrust enforcement. They can bring suits under their state's antitrust laws, which mostly—though not entirely—track the federal antitrust laws. State attorneys general can also bring suit under federal antitrust laws with parens patrie standing, a special type of standing that allows governments to bring suit on behalf of their residents. We review some of the biggest recent case developments from state attorneys general, as well as legislative updates on laws that may introduce new standards in evaluating antitrust cases.
