Cedarbaum, Jonathan G.

Jonathan Cedarbaum rejoined the firm in 2011 after spending two years in the leadership of the Justice Department's Office of Legal Counsel, where he ultimately served as Acting Assistant Attorney General in charge of the Office, which provides authoritative legal advice to the White House, the Attorney General, and all executive branch departments and agencies. Mr. Cedarbaum has a diverse litigation practice, focusing especially on False Claims Act, Administrative Procedure Act, IP/antitrust and international cases. He also counsels clients on regulatory matters and represents them before administrative agencies and congressional committees—particularly in the areas of data security and privacy, health care and financial services.


During his time at OLC, Mr. Cedarbaum was deeply involved in the development and early implementation of the Dodd-Frank and Affordable Care Acts. As a member of the Justice Department’s senior leadership and as a legal counselor to senior officials across the government, he was also involved in numerous other statutory and regulatory initiatives, including in the areas of cybersecurity and data privacy, economic sanctions, patent reform, procurement reform and energy development.

Earlier in his career, Mr. Cedarbaum had done two additional stints at the Justice Department: two-and-a-half years as an Attorney-Advisor in the Office of Legal Counsel (1999-2002) and a year as a Bristow Fellow in the Office of the Solicitor General (1997-1998). Mr. Cedarbaum has also served as Deputy Chief of Staff to the President of the International Criminal Tribunal for the Former Yugoslavia (2002-2003) and as a legislative assistant for a Member of Congress (1985-1986).

Fourth Circuit Holds cGMP Violations Do Not Create False Claims Under Medicare and Medicaid

In the first appellate decision of its kind, the U.S. Court of Appeals for the Fourth Circuit held on February 21, that because compliance with the Food and Drug Administration’s Current Good Manufacturing Practices (cGMP)  regulations is not a precondition for reimbursement under Medicare and Medicaid, violations of the cGMP regulations by themselves cannot form the basis for False Claims Act claims under those programs.

False Claims Act: 2013 Year-in-Review

The False Claims Act (FCA) saw another year of increased activity in 2013, with new qui tam suits hitting an all-time high of 753, a rise of more than 100 over 2012. In fiscal year 2013, the federal government brought in $3.8 billion—the fourth year in a row of more than $3 billion in recoveries. As in the past, the healthcare and pharmaceuticals sector accounted for the biggest share, with $2.6 billion recovered. Procurement saw a jump, more than doubling to $890 million. Financial institutions remained a substantial target, and both the government and private plaintiffs were increasingly bringing claims against recipients of grant and loan funds as well as contractors. Activity at the state level increased as well, with many states expanding the reach of their own false claims statutes, and both state attorneys general and private plaintiffs making aggressive use of new theories of liability.
