Overview

Adeel Mangi is a litigator with extensive experience trying high-stakes cases to judges and juries in state and federal courts around the country. 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.”

Chambers USA quotes clients as saying Adeel is “one of the best litigators in the country right now,” “a first-class trial lawyer with excellent instincts,” and “one of the best up-and-coming trial attorneys in the country.” Clients quoted by Chambers also noted that “few, if any, attorneys can match his oral advocacy” and highlighted his “unflinching advocacy,” “masterful grasp of the facts of a case,” and ability “to think many steps ahead and devise winning strategies.”

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.

Benchmark awarded its "Impact Case of the Year" recognition for 2023 to Adeel and his team. In 2023, Adeel was also named to The National Law Journal’s General Litigation Trailblazers list. In 2022, he was featured in The American Lawyer’s ‘Litigators of the Week’ section in connection with a jury trial verdict. He has also been highlighted repeatedly, including in 2022, as a “Client Service All-Star” by The BTI Consulting Group. This award recognizes attorneys who “stand above all the others in delivering the absolute best in client service.”

Earlier, Adeel was named a "Future Star" for the years 2017-2022 by Benchmark Litigation. From 2016-2018 Adeel was also named to Benchmark’s “40 & Under Hot List.” The list recognizes “the achievements of the nation’s most accomplished legal partners” ages 40 and under. Adeel was previously named a “2014 Rising Star” by the New York Law Journal, which recognizes the most promising lawyers under the age of 40 who have demonstrated that they are top contributors to the practice of law and their communities; a “Rising Star” by the Minority Corporate Counsel Association’s Diversity & the Bar magazine, which selected 12 up-and-coming attorneys for 2014; and as one of the National Asian and Pacific American Bar Association's "Best Lawyers Under 40" for 2014. Adeel is also a 2013 graduate of the Microsoft Litigation Group's highly prestigious Trial Advocacy Academy.

Adeel has also litigated numerous high-profile civil rights cases. These included some of the most closely watched religious freedom cases of the Trump era, which involved two different Muslim communities denied permission to build mosques in Bernards Township and Bayonne. These lawsuits were the subject of seven editorials in New Jersey’s largest newspaper and were covered extensively in the national press. Both cases eventually resulted in settlements under which the mosques were approved and the municipalities involved paid significant compensation to the affected Islamic groups. Adeel also tried a lawsuit in 2020 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 filed a series of amicus briefs on behalf of a coalition of cross-faith religious groups on issues including DACA, the border wall, and on LGBTQ+ civil rights issues. Between 2017 and 2019, work pioneered and led by Adeel was awarded the "Outstanding Service Award" by the Alliance of Families for Justice; the “Legal Leadership Award” by the American Civil Liberties Union—New Jersey; the “Champions of Justice” award by the Muslim Bar Association of New York; the “Religious Liberty Award" (2018) and the “Landmark” litigation award (2017) by the New Jersey Muslim Lawyers Association; and the Trailblazer Award by the South Asian Bar Association of New Jersey. Adeel was also declared Pro Bono Attorney of the Year by the South Asian Bar Association of New York. Also in 2017, Adeel Chaired the Federal Bar Council’s annual Law Day Dinner celebrating the Rule of Law before some 850 attorneys and federal judges.
