Overview

Adeel Mangi is the Chair of the Trial Practice at Linklaters. He is widely regarded as one of the country’s leading trial lawyers, with a remarkable record handling high-stakes commercial disputes in state and federal courts. 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.

In 2025, Adeel was named “Attorney of the Year” by Law.com and New Jersey Law Journal for his outstanding achievements and exceptional leadership in the U.S. litigation field over the past year, and to Forbes’ inaugural “America’s Top Lawyers” list.

Adeel's work has been recognized through numerous professional awards (see recognition section). He has also litigated numerous high-profile civil rights cases (see pro bono section).

Beyond the office

Pro bono experience

Adeel has litigated numerous high-profile civil rights cases. These included closely watched religious freedom cases that 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 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.

Recognition

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.”
