For almost 30 years, Lee Armstrong has successfully litigated and tried some of the most complicated bet-the-company disputes across the country in matters involving finance, banking, bankruptcy, consumer class actions, employment, M&A, and securities.

Lee's representations, present and former, illustrate the breadth of his practice. Currently, Lee's docket includes: defending a financial institution against claims of structured finance trade secret misappropriation; defending a multinational retailer against a supplier's multibillion dollar breach of contract claims; and co-leading SiriusXM's national defense against various consumer class actions, including the recent successful resolution of a $100 billion Telephone Consumer Protection Act class action. In addition, Lee recently argued and won a multimillion dollar breach of contract summary judgment on behalf of an aviation company and obtained dismissal for Citizens Bank against securities class actions, a relationship that began more than a decade ago when Lee led the successful defense of then-parent RBS in the multibillion dollar securities class action arising from Enron's collapse.

Lee has acted as trial counsel in the most complex financial institutions cases and has litigated one of the most complex bankruptcies in history, Chrysler LLC: a 42-day nonstop effort that involved multiple evidentiary hearings and appellate practice. Lee also successfully has litigated trademark disputes (e.g., securing a trial verdict exonerating Citizens Bank against infringement claims and successfully arguing the Sixth Circuit appeal), numerous employment restrictive covenant matters, and failed M&A and joint venture disputes.
