Chicago, IL


Tony is an accomplished litigator with 40 years of experience in a broad range of state and federal civil trial and appellate matters. As counsel for both plaintiffs and defendants, he has first-chaired numerous jury and bench trials in federal and state courts and argued a wide variety of appeals throughout the country, including in the Illinois Supreme Court. A Principal of the firm since 1979 and a member of the Management Committee from 2010-2013, Tony served as Chair of the Litigation & Dispute Resolution practice group for more than 20 years.

Tony's practice encompasses complex business and financial litigation, concentrating in four major areas: (1) business disputes, including non-compete/non-solicitation agreements, (2) insurance coverage, (3) appeals and (4) class action defense. He represents individuals, privately held companies and publicly traded corporations in the areas of business fraud and related torts, unfair competition, labor-related litigation, toxic torts, environmental litigation, employment discrimination (including age and other types of discrimination), trademarks, ERISA litigation, trade dress matters, technology litigation, RICO fraud and securities litigation (including stock purchase agreements, notes and contracts).

"My main job as a litigator is to try to keep my clients out of litigation. But when that is impossible, then my job is to do what I can to help them win."

Representative successes:

  • In March, 2016, as co-counsel for the plaintiff, Tony obtained an $80 million jury verdict for our client against an insurer-related company for fraud, tortious interference, and violation of the Illinois False Claim Act.
  • In 2014, Tony successfully argued before the Illinois Appellate Court an important insurance coverage case involving class actions.
  • Tony recently succeeded in settling on very favorable terms a $100 million ERISA case related to the Madoff scandal. 
  • In 2013, Tony won a significant appeal in the area of restrictive covenants that clarified Illinois law regarding adequate consideration; the case has been called the most important restrictive covenant decision in 2013.
  • Tony has argued and won, among others, appeals in the Illinois Supreme Court, the Illinois Appellate Court, and the Seventh Circuit Court of Appeals that have made law in the insurance area, RICO and Truth in Lending; one of his insurance cases, Valley Forge v. Swiderski, was designated by a leading publication as one of the top ten insurance cases in 2006.
  • In 2011, Tony argued and won an appeal in a case of first impression in Illinois that clarified the method of giving notice of rescission under the Truth in Lending Act (TILA).
  • As lead counsel in a seven-day jury trial in state court in Boise, Idaho, Tony successfully defended (and recovered fees and costs for) a firm client in a trade secrets, breach of fiduciary duty and unfair competition case in which the plaintiff was seeking seven-figure damages.

  • Tony has successfully argued two separate insurance coverage cases before the Illinois Supreme Court that expanded policyholders' rights.
  • As lead counsel in a complex FINRA arbitration hearing lasting five weeks, Tony obtained a favorable award for a hedge fund client against a public options trading firm. Tony facilitated an advantageous settlement in a significant non-compete case for a highly successful trader in the high-frequency, automated 'black-box' electronic trading industry.
  • Tony successfully resolved a complex security fraud case against a prominent broker-dealer involving exotic financial investments.

Among other publications, he co-authored the 2012 e-publication How to Overspend and Lose Your Case: Ten Common Mistakes in Big Ticket Litigation [Kindle Edition], and contributed a chapter, "Ethical Considerations: Does Trial Consulting Help Achieve Justice," in the 2006 IICLE publication Inside and Outside the Jury Box (updated in 2011). Tony also authored an important treatise on non-compete agreements, Covenants Not to Compete: Forms, Tactics and the Law, and various journal articles for the CBA Record, Trade Secret Law Reporter, Midwest In-House Counsel and Business Tax Report.

Tony has extensive experience in legal writing and editing and taught legal writing at Loyola University Chicago. While in law school, he served on the Loyola Law Journal.
