Future Star

Practice area:


Joshua Matz is a partner at Kaplan Hecker & Fink LLP. His practice includes complex commercial disputes, civil rights, constitutional law, and Supreme Court and appellate litigation. In 2020, Joshua was recognized by The National Law Journal as a “D.C. Rising Star” and by Benchmark Litigation as a “Future Star” and member of its “40 & Under Hot List.” In January 2021, Joshua was commissioned by Governor Andy Beshear as a Kentucky Colonel—the Commonwealth’s highest honor—for successfully defending Governor Beshear’s COVID-19 public health measures at the Supreme Court. In February 2021, Joshua took a leave of absence from the firm to serve as Impeachment Counsel to the House Judiciary Committee for the second Senate trial of President Trump; he previously served among counsel to the House Judiciary Committee for the first impeachment and trial of President Trump. 

Joshua litigates a wide array of commercial cases, ranging from contract, fraud, and misappropriation disputes to consumer protection and sex discrimination matters. He advises companies on regulatory compliance, participates in sensitive internal investigations, and helps to formulate administrative and constitutional challenges to city and state regulation. And along with several of his colleagues at Kaplan Hecker, Joshua represents Columbia University in class action tuition refund litigation arising from its response to the pandemic. 

Joshua is also an experienced defamation litigator. He represents E. Jean Carroll in a case against Donald J. Trump for defamatory statements Trump made in response to Ms. Carroll’s public revelation that he had sexually assaulted her. He represents Moira Donegan in a defamation case arising from the “Shitty Media Men” list. He represents Liz Mair in a defamation case brought by Rep. Devin Nunes relating to her political criticism. And he represents Stanford Medical School faculty who were threatened with a defamation suit for scientific criticism of policies advocated by former White House Coronavirus Advisor Dr. Scott Atlas. 

Joshua maintains a substantial civil rights and constitutional practice. His cases have ranged across LGBTQ rights, religious liberty, freedom of speech, privacy, firearm regulation, the separation of powers, the right to counsel, due process, and the scope of constitutional remedies. He has represented individual clients, civil rights organizations, current and former government officials, cities, states, and congressional committees. Joshua has also published two books with Professor Larry Tribe of Harvard Law School and has established himself as a sought-after expert on constitutional issues. 

Joshua holds a JD (magna cum laude) from Harvard Law School. He clerked for Judge J. Paul Oetken (SDNY), Judge Stephen Reinhardt (Ninth Circuit), and Justice Anthony Kennedy (U.S. Supreme Court).
