Andrew Kassof is one of the leaders of Kirkland’s litigation practice and serves on the Firm’s Executive Committee.
In back to back months this year, The American Lawyer recognized Andrew as its national “Litigator of the Week” for work on different cases—once for a defense victory in a False Claims Act suit in federal court in Illinois and the second for a Delaware Chancery Court victory for a buyer in a broken deal dispute. In the latter, the court “adopted” Andrew’s oral argument as “the grounds for its opinion” after “finding that Mr. Kassof’s exposition, explanation, and reasoning aligned with what I would write in a written opinion.” The next month, Andrew secured the dismissal of another False Claims Act case for a different client in federal court in Florida.
Andrew’s commercial litigation practice cuts across different industries and types of cases. Twice he has tried billion dollar cases to successful verdicts—once on the plaintiff side in a fraud-based suit in federal court in NY, and the other for the defense in a False Claims Act case in Texas; has successfully first-chaired dozens of additional cases in state courts, federal courts, and arbitration; and has represented corporate clients from different industries in various types of complex commercial disputes, False Claims Act suits, class actions, and other cases in state and federal courts in nearly every state in the country.
In the past year, Andrew has secured awards for plaintiffs and dismissals for defendants in commercial cases seeking hundreds of millions of dollars in Illinois, Minnesota, New York, Texas, Massachusetts, Delaware and California. In the False Claims Act space, Andrew has litigated and obtained dismissals and judgments in Massachusetts, Texas, Florida, New Jersey, Illinois and California. In sports cases, Andrew has successfully represented various sports teams, including the Chicago Cubs, Los Angeles Rams and Los Angeles Angels, sports owners, the United States Soccer Federation, sports leagues, and players and coaches from the NBA, NFL and college. Law360 named Andrew one of five “Sports MVPs” in its national “MVPs of the Year” list.
Andrew also leads Kirkland’s alternative fee program for the litigation group and often handles both plaintiff and defense-side cases on flat fee, success fee or contingency fee structures for multiple firm clients.
