His commercial litigation experience encompasses business disputes, false advertising, consumer protection and fraud, FCA, and extensive class action defense work; antitrust and unfair competition matters; and intellectual property litigation, such as trademarks, patents, and trade secrets.
Jon served as the Nation’s lead environmental civil and criminal enforcement official and litigator, as Acting Assistant Attorney General for the Environment & Natural Resources Division (“ENRD”) of the U.S. Department of Justice (DOJ). Jon led ENRD’s 425 lawyers, overseeing 6,500 active matters and managing an annual budget of more than $150 million. Jon brings highly experienced executive leadership from among the most senior level of DOJ on white collar and regulatory enforcement, as well as on federal policymaking and rulemaking development and challenges. He speaks with authority on government decision-making processes, and the arguments and perspectives that move regulators and enforcers, best advising and positioning clients to deal with challenges.
Jon argued many of the government’s most significant cases during his time with the DOJ. This included the Navigable Waters Protection Rule and Clean Water Rule Repeal (10th Cir., district courts), the Affordable Clean Energy Rule and Clean Power Plan Repeal (D.C. Cir), defense of EPA actions on pesticide tolerances under FIFRA and the FDCA (9th Cir. en banc), among numerous others. Jon represented the United States in trial courts in both enforcement and defensive cases, including federal enforcement action against Jeffrey Lowe and the Tiger King Park, of Netflix fame, securing a first-of-its-kind injunction for violations of the Endangered Species Act and Animal Welfare Act. Jon directed the litigation and briefing of scores of additional federal cases nationwide, covering all of the major environmental and natural resources statutes, such as the Clean Air Act, the Clean Water Act, FIFRA (pesticides), FDCA (food safety), TSCA (toxics), CERCLA (land remediation), RCRA (waste), National Environmental Policy Act, Federal Land Policy and Management Act, and numerous other land- and resource-management statutes.

Circuit, regarding the most significant climate change regulations by EPA, as well as the preemptive scope of the Clean Air Act. Jon also litigated climate change-related credit and trading schemes and international agreements in district court. During Jon’s time in leadership at ENRD, it successfully defeated one of the most wide-ranging lawsuits regarding climate change to date—obtaining a stay pending interlocutory appeal and dismissal just weeks before a scheduled three-month trial on federal government liability for climate change.
An accomplished trial lawyer, prior to working at DOJ, Jon was a partner in the Washington, D.C. office of another global law firm. He not only represents clients in court, but creatively counsels corporations on balancing business needs and realities with a broad range of litigation risks and compliance obligations.

Professor of Law, Georgetown University Law Center
Nicholas Quinn Rosenkranz teaches constitutional law and federal jurisdiction, and he writes articles for the Harvard Law Review and the Stanford Law Review.
He is currently developing a new theory of constitutional interpretation and judicial review. The first installment, entitledThe Subjects of the Constitution, was published in the Stanford Law Review in May of 2010, and it is among the most downloaded articles about constitutional interpretation, judicial review, and/or federal courts in the history of SSRN. The second installment, The Objects of the Constitution, was published in May of 2011, also in the Stanford Law Review. And the comprehensive version is forthcoming as a book by Oxford University Press.
Rosenkranz has served and advised the federal government in a variety of capacities. He clerked for Judge Frank H. Easterbrook on the U.S. Court of Appeals for the Seventh Circuit (1999-2000) and for Justice Anthony M. Kennedy at the U.S. Supreme Court (October Term 2001). He served as an Attorney-Advisor at the Office of Legal Counsel in the U.S. Department of Justice (November 2002 - July 2004). He often testifies before Congress as a constitutional expert—most recently before the House Financial Services Oversight Subcommittee, regarding the Obama Administration's use of bank settlement agreements to circumvent the Appropriations Clause. He has also filed briefs and presented oral argument before the U.S. Supreme Court. His most recent Supreme Court brief, in Los Angeles v. Patel, was cited by Justice Alito in dissent.
