Biography

About Paul E. Slater — Over 56 years of Illinois litigation experience

Paul E. Slater is an attorney based in Chicago, ILLINOIS. The practice focuses on Litigation. Paul has over 56 years of legal experience.

A firm founder, visionary leader, and skilled litigator, Paul Slater handles high-stakes antitrust cases for private and public enterprises, including Fortune 500 companies. He pioneered the opt-out practice, representing companies as individual plaintiffs in industry-wide multidistrict antitrust litigation. This practice enables clients to tailor their claims and maximize their recoveries outside of class action proceedings, which often fail to meet individual client needs.

Mr. Slater represents clients in wide-ranging industries, including national drugstore, grocery store, and restaurant chains; domestic and international airlines; the leading air freight service provider; national car rental companies; and major shopping, internet, and media marketing companies. He has successfully resolved price-fixing, monopolies, customer allocation, anticompetitive vertical agreements, and other restraint-on-trade cases.

Among his many successes are first-of-their-kind antitrust cases, including ones against credit card companies, and industry-impacting actions against pharma giants for drug overcharging. Clients appreciate Mr. Slater’s ability to optimize their recoveries while working out resolutions that improve the parties’ relationship and results in better business terms for the future.

Before founding the firm, Mr. Slater taught at the University of California School of Law at Berkeley (Boalt Hall) and then at Northwestern University School of Law, where he was a professor of antitrust law and then an adjunct professor teaching an advanced antitrust law course for 35 years. Highly respected for his legal acumen and insight, he has been cited by the U.S. Supreme Court on several occasions. His exceptional knowledge of antitrust laws is rare, if not unrivaled.
