Overview
For three consecutive years (2023-2025), Benchmark Litigation has named Adeel to its lists of the “Top 100 Trial Lawyers” in the U.S., which consists of “partners who have been venerated by peers and clients as being the best in breed at the nuanced practice of trial law . . . based on an intensive peer-and-client review." Benchmark Litigation also named Adeel as a Litigation Star for each of the last three years (2023-2025) and has noted that peers describe Adeel as “meticulous and relentless,” and “an unflappable whiz at everything he does.”
Adeel was nominated to the United States Court of Appeals for the Third Circuit by President Biden. That nomination expired without a vote in the United States Senate after the 2024 presidential election. Adeel was the first Muslim-American ever nominated to a Circuit Court of Appeals. He wrote a letter to President Biden regarding his nomination that was described by one commentator as “required reading for anyone who wants to know how to deal with opponents of pluralism, diversity, and democracy.”
Adeel secured the largest jury verdict in the history of the Virginia court system with a $2 billion verdict after a seven-week jury trial in a case involving theft of trade secrets in the software industry—a case that is now on appeal. Adeel also secured the largest settlement with New York state in history in cases involving the death of a state prison inmate on the morning of closing arguments after a two-and-a-half week jury trial in the Southern District of New York. Adeel has represented other clients in a variety of industries in state and federal courts and arbitrations around the country across a range of subject matters including commercial contracts, false advertising, and consumer protection statutes.
Adeel's work has been recognized through numerous professional awards (see awards and accolades section). He has also litigated numerous high-profile civil rights cases (see pro bono section).
Pro bono
Adeel also tried a lawsuit involving the death of a mentally ill Black inmate who was alleged to have been killed by white prison guards in a retaliatory beating. The resulting landmark settlement included an unprecedented provision requiring New York to install a comprehensive network of video recording cameras and microphones throughout the Sullivan Correctional Facility.
Adeel has also filed a series of amicus briefs on behalf of a coalition of cross-faith religious groups on issues including LGBTQ+ civil rights.
