TACY FLINT is a premier appellate litigator who has won victories for her clients in high-stakes cases at all levels of the judiciary, through an uncommonly insightful legal perspective combined with zealous advocacy and business acumen.
Tacy advocates for her clients from complaint through appeal. She is a superlative writer, having won cases with critical motions and briefs at all stages of litigation. In the words of one of Tacy’s clients, “She’s the heavyweight legal thinker and strategist you call when you want the knockout punch, be it an early dispositive motion or a Supreme Court brief. Tacy has a unique ability to tell her client’s story. A brief or motion written by Tacy does not simply set out key cases and facts. It builds the narrative.”
Tacy is equally renowned for her oral argument skills. She has argued in the U.S. Supreme Court, the Illinois Supreme Court, and federal and state courts of appeals across the country. Repeatedly, Tacy has won historic rulings for her clients—including vacatur of large jury verdicts, dispositive rulings in cases seeking billions of dollars in damages or injunctions posing an existential threat to her clients, and case-critical rulings on evidentiary and other legal issues.
Tacy graduated first in her class with highest honors from the University of Chicago Law School. She served as a law clerk to Justice Stephen Breyer of the U.S. Supreme Court and Judge Richard Posner of the U.S. Court of Appeals for the Seventh Circuit.
