At Platkin LLP, we use the law to drive meaningful change in the face of injustice. When our democracy is under threat, powerful wrongdoers harm people with impunity, or gun violence endangers our communities, we fight back fearlessly and win.
Platkin LLP is a mission-driven law firm founded by former New Jersey Attorney General (AG) Matthew Platkin and a talented team of litigators from the AG’s office. Together, they led some of the nation’s most consequential cases and have experience holding harmful actors accountable, including the Trump Administration, large technology companies, reckless gun manufacturers, and other powerful interests harming consumers. From lawsuits that demand accountability at the highest levels to cases that ensure the public’s safety, protect consumers, and uphold the foundations of our democracy, we don’t just win—we set legal precedents to protect the public for generations to come.
Our team is experienced in handling high-stakes litigation in trial and appellate courts, as well as sensitive investigations across a range of practice areas. We have a proven track record of being thorough, independent, and unafraid to take on all aspects of tough legal fights—and winning.
We represent governments, private individuals, and organizations across a wide variety of complex legal matters, including consumer protection, false claims, environmental, securities, and antitrust cases, among others. Our attorneys handle all aspects of litigation—from filing the complaint through an appeal—and are not afraid to confront the most powerful companies in the world or defend clients’ interests when they are being harmed.
With extensive experience in both state and federal appellate courts, we approach each appeal by examining every case with a fresh perspective. We defend trial wins in the face of uncertainty, and we obtain reversals of unfavorable rulings. We also provide candid consultations for clients seeking an evaluation or second opinion on pending litigation risks and the odds of ultimate success.
Our expertise conducting sensitive investigations is deep and we have a hard-earned reputation for independence and integrity in every matter we undertake. Our attorneys have conducted large-scale investigations and served as independent monitors of corporate institutions to implement compliance measures and best practices.
We have led numerous high-profile matters in the face of intense public scrutiny. We understand how to navigate a crisis and deliver results for our clients when they need them most.
We represent individuals and organizations seeking to effect systemic change in the government or private sector. As former government attorneys who have filed and litigated precedent-setting and industry-changing cases, we know how to advance justice through litigation. We also work closely with nonprofits and advocacy groups, serving as coalition builders and trusted advisors in the pursuit of shared public-interest goals.
