Whether pursued on an individual basis or in the class setting, private antitrust litigation has played, and continues to play, an important role in the development of modern antitrust jurisprudence. And with notable Supreme Court cases like Twombly, Comcast, and Matsushita, private antitrust litigation has had an outsized influence on federal litigation more generally.

The Class Action and Private Litigation Committee monitors and provides a forum to discuss class action and private litigation antitrust law and policy. The Committee focuses on a wide range of issues relating to antitrust class action litigation, including class certification, procedural issues, substantive claims, and damages issues. The committee hosts several panel discussions each year that offer its members the opportunity to stay up-to-date on the latest developments and hot topics in the field while earning CLE credit. In recent years, the committee has hosted panels concerning private litigations against digital platforms, the rising use of litigation finance, and developments in class action jurisprudence.

The Committee also affords its members the opportunity to participate in other activities: members are encouraged to network at our events, present on topics and cases of recent interest at Committee meetings, plan and/or participate in Committee programming, and contribute written submissions on class action-related issues for the Section’s newsletter, Competition Chronicles.
