With the passing of Justice Ruth Bader Ginsburg, President Donald Trump has nominated her successor, Judge Amy Coney Barrett to fill the open seat on the U.S. Supreme Court. On Monday, Oct. 26, the full Senate is scheduled to vote on her confirmation.

We have written about the antitrust views and backgrounds of other justices on the court, such as Justice John Paul Stevens, and more recently Justice Ginsburg, Justice Neil Gorsuch and Justice Brett Kavanaugh; however, Judge Barrett remains the wild card in this area of the law. She has only been on the U.S. Court of Appeals for the Seventh Circuit since 2017 and has spent most of that time on cases with little connection to the antitrust world. Despite the Seventh Circuit being well known for its antitrust jurisprudence, none of the opinions in which Barrett has participated in provide much insight into her approach to or views on the antitrust laws. Reviewing the panels on which she has sat, Barrett only participated in a total of seven antitrust cases, writing only one majority opinion and authoring no concurrences or dissents. As such, a review of any of those opinions provides limited information about what Barrett specifically thought of the arguments counsel made or the underlying legal issues.
