Joshua Matz serves in an Of Counsel capacity at Kaplan Hecker & Fink LLP. He specializes in trial and appellate litigation, with a focus on constitutional law and civil rights. He entered private practice after clerking for Judge J. Paul Oetken of the Southern District of New York, Judge Stephen Reinhardt of the Ninth Circuit Court of Appeals, and Justice Anthony M. Kennedy of the United States Supreme Court. In 2014, Forbes named Joshua to its “30 under 30” Law & Policy List—and in 2016 it named him an “Alumni All-Star” of past honorees.

I love the law not only because I enjoy solving hard puzzles, but also because I care passionately about seeking justice in the world.

Before joining Kaplan Hecker, Joshua worked in private practice on a wide array of commercial cases, ranging from complex contract and bankruptcy disputes to False Claims Act litigation and white collar investigations. There, he honed valuable skills that he brings to bear on all of his matters at Kaplan Hecker LLP.

In addition to his commercial experience, Joshua maintains an active and growing civil rights practice. He has litigated a diverse set of questions relating to LGBTQ rights, religious liberty, freedom of speech, defamation liability, the Second Amendment, the Foreign and Domestic Emoluments Clauses, the Prison Litigation Reform Act, California’s anti-SLAPP statute, and the Ku Klux Klan Act.

Recently, Joshua represented a coalition of constitutional scholars as amici curiae throughout the travel ban litigation. In its en banc opinion upholding an injunction against the second version of President Trump’s travel ban order, the Fourth Circuit cited his amicus brief several times. The Economist called Joshua’s brief a “persuasive and skillfully targeted argument,” and Slate described the court’s opinion as “a striking vindication of the constitutional theory put forth in an amicus brief by a group of scholars led by . . . Joshua Matz.”

Kaplan Hecker & Fink LLP offers a compelling new vision of the law firm environment.  As the legal profession evolves in this uncertain era, the time has come for a law firm steeped in humane values and committed to making the world a better place.

Joshua has written for diverse audiences about cutting-edge legal issues. His articles have appeared in The Washington PostThe Wall Street Journal, The GuardianThe AtlanticACS Blog, and Wired. He has also delivered talks at the Cambridge Public Library, the 92nd Street Y, Politics & Prose, the National Constitutional Center, and the University of Pennsylvania. From 2011 to 2012, he wrote weekly news round-ups for SCOTUSblog.

Since March 2017, Joshua has served as the Publisher of Take Care, a legal website that offers accessible coverage of the President and the Administration. He also serves as an Adjunct Professor of Law at Georgetown Law School, where he and Amir Ali co-teach a class entitled, “Constitutional Litigation and the Current Administration.”

In March 2012, Joshua and Harvard Law Professor Larry Tribe published “The Constitutional Inevitability of Same-Sex Marriage,” 71 Md. L. Rev. 471 (2012). In June 2014, they published an award-winning book, Uncertain Justice: The Roberts Court and the Constitution (Henry Holt & Co.). In May 2018, they published their second book together, To End a Presidency: The Power of Impeachment (Basic Books).

Joshua holds a BA (magna cum laude) from the University of Pennsylvania and an MSt (with distinction) from Oxford University. He graduated magna cum laude from Harvard Law School, where he served as Articles & Book Reviews Chair of the Harvard Law Review and president of the American Constitution Society. During law school, he worked at the Public Citizen Litigation Group and the Federal Defender of New York. After graduating, he spent a summer at Neufeld Scheck & Brustin LLP, where he worked on civil rights cases arising from wrongful convictions.
