Justin’s robust experience representing plaintiffs and defendants in complex commercial litigation, including, without limitation, antitrust, commodities, corporate fiduciary duty, fraud, intellectual property, and securities cases, has forged him into a formidable advocate on behalf of plaintiffs. He has amassed a track record of results through a wealth of first-chair experience, especially in trials, on behalf of asset managers, companies, government entities, public and private institutional investors, and individuals in United States federal and state court, arbitration, and abroad.

In 2018, Justin was honored as a Rising Star under 40 years of age by Law360® in Class Actions, a prestigious award given to a select few “top litigators and dealmakers practicing at a level usually seen from veteran attorneys.” He has also been honored by Lawyers of Distinction® in securities law and by Super Lawyers® as a Rising Star in antitrust and securities law.

Justin played a key role in the In re Petrobras Securities Litigation (S.D.N.Y.), arising from a multi-billion-dollar bribery and price-fixing scheme. In 2018, lead counsel achieved a historic $3 billion settlement for the class, as well as precedent-setting legal rulings. This is the largest securities class-action settlement in a decade, the largest class-action settlement ever involving a foreign issuer, and the fifth-largest class-action settlement ever achieved in the United States.

Justin played pivotal roles in several other class actions that resulted in total recoveries amounting to over $270 million for plaintiffs: In re Altair Nanotechnologies Securities Litigation (S.D.N.Y.), recovery of $1.5 million; Carmack v. Amaya Inc., et al. (D.N.J.), recovery of $5.75 million; Calfo v. Messina, et al. (S.D.N.Y.), recovery of $1.65 million; Kaplan v. S.A.C. Capital Advisors, L.P., et al. (S.D.N.Y.), recovery of $135 million; Mauss v. NuVasive, Inc., et al. (S.D. Cal.), recovery of $7.9 million; In re OSG Securities Litigation (S.D.N.Y.), recovery of over $30 million; Perez v. Higher One Holdings, Inc., et al. (D. Conn.), recovery of $7.5 million; In re Retrophin, Inc. Securities Litigation (S.D.N.Y.), recovery of $3 million; Springer v. Code Rebel Corporation (S.D.N.Y.), recovery of $1 million; and In re Yahoo! Inc. Securities Litigation (N.D. Cal.), recovery of $80 million. He also played integral roles in representing plaintiffs in the In re Aluminum Warehousing Antitrust Litigation (S.D.N.Y.), In re Generic Digoxin and Doxycycline Antitrust Litigation (E.D. Pa.), and In re Treasury Securities Auction Antitrust Litigation (S.D.N.Y.).

Prior to predominantly representing plaintiffs, Justin practiced at a premier, world-renowned large law firm that mostly represented defendants in bet-the-company litigation. His practice involved U.S. federal and state and international complex litigation, arbitration, and internal and regulatory investigations, with an emphasis on antitrust, commodities, and securities litigation. He played integral roles in representing defendants in Alaska Electrical Pension Fund v. Bank of America, N.A., et al. (S.D.N.Y.), Garofalo v. Revlon, Inc., et al. (D. Del.), In re Foreign Exchange Benchmark Rates Antitrust Litigation (S.D.N.Y.), and In re LIBOR-Based Financial Instruments Antitrust Litigation (S.D.N.Y.). Also, Justin played a pivotal role in iBasis Inc.’s lawsuit against Koninklijke KPN NV in connection with an alleged inadequate tender offer, which settled during trial in 2009 before the Delaware Court of Chancery. Justin’s zealous advocacy has been demonstrated further through his pro bono work that has achieved staggering results for those with disabilities: for example, for his work in representing plaintiffs in Toney-Dick v. Doar (S.D.N.Y.), he was awarded a 2013 Pro Bono Publico award from The Legal Aid Society.

An avid writer, Justin is the co-author of the Delaware Business Court Insider article entitled Lead Plaintiffs’ Shareholdings Draw Chancery Review. He contributed to chapters in the American Bar Association’s Antitrust Law Developments, Matthew Bender’s Antitrust Laws and Trade Regulation, the American Bar Association’s Model Jury Instructions in Civil Antitrust Cases, the Practicing Law Institute’s Securities Litigation, A Practitioner’s Guide, and Professor Deborah W. Denno’s chapter entitled When Willie Francis Died: The “Disturbing” Story Behind One of the Eighth Amendment’s Most Enduring Standards of Risk, in John H. Blume and Jordan M. Steiker’s book, Death Penalty Stories. Justin was also a speaker and presenter at the Knowledge Group’s Conference on October 20, 2015, entitled Latest Trends and Developments in Federal Securities Investigation: What to Expect in 2015 and Beyond.

Justin earned his J.D. degree, cum laude, from the Fordham University School of Law. During law school, he served as a member of the Fordham Urban Law Journal and as a business editor of the Fordham Dispute Resolution Society. He served as a judicial intern to the Honorable Stuart M. Bernstein of the United States Bankruptcy Court for the Southern District of New York. Justin earned his B.B.A. degree, with distinction, from the University of Michigan Stephen M. Ross School of Business, with an emphasis in finance and corporate strategy. During business school, he was awarded a University of Michigan Alumnae Council MBNA Scholarship.

Justin is admitted to practice law in New York and the United States District Courts for the Eastern and Southern Districts of New York and Eastern District of Michigan. He is a member of the American Bar Association and the New York City and State Bar Associations.
