Zac Madonia is a litigator who primarily practices in the areas of class action defense and complex commercial litigation. He represents corporate clients from a diverse range of industries – including mortgage and consumer lending, pharmaceutical manufacturing and distribution, and healthcare – facing class and mass actions in federal and state courts across the country.

Zac's practice spans the substantive spectrum. For example, Zac recently obtained dismissal with prejudice of a putative nationwide class action brought against a student lender that asserted civil RICO claims and alleged violations of various federal and state borrower protection statutes. He also obtained dismissal with prejudice (affirmed on appeal to the D.C. Circuit) of a False Claims Act action brought against a chemical and material sciences company that sought billions in damages based upon the alleged failure to report risk information to the EPA. Other substantive areas in which Zac regularly advises clients include antitrust and competition, commercial fraud, securities and shareholder derivative litigation, breach of contract, and intellectual property.
