A quarterly update on FCA Enforcement and Qui Tam Litigation from Arthur Fritzinger and Calli Padilla.

Arthur is a respected white collar defense attorney, representing companies and individuals in government inquiries, criminal proceedings, civil and administrative enforcement actions, and internal investigations. His clients include Fortune 500 companies, executives and directors of publicly traded and private companies, small businesses and owners, universities, and nonprofits.

Arthur focuses his practice primarily on False Claims Act (FCA) defense and has deep experience in the areas of health care fraud and abuse, anti-kickback violations, and government contracts fraud. He responds to qui tam and whistleblower suits as well as government-initiated inquiries, counsels on defense strategy and retaliation avoidance, defends civil investigative demand letters, leads sensitive internal investigations, and positions clients for quick and quiet resolutions.

He also has broad experience defending clients in non FCA-related governmental allegations of mail fraud, public corruption, sanctions violations, insider trading and other securities fraud, and tax fraud, as well as defeating fraud claims in a purely commercial context.

Arthur frequently represents clients in state and federal courts throughout the country. But as a lifelong Philadelphian, who matriculated, clerked, trained, and practices in Philadelphia, Arthur brings invaluable knowledge of the local bar and bench to every local engagement.

Beyond his private practice, Arthur regularly handles pro bono matters through the Pennsylvania Innocence Project. He was a core member of the legal team that won release for Dontia Patterson, who was incarcerated as a teenager and served 10 years in prison for a murder he did not commit. The District Attorney’s Office ultimately joined the defense request for the conviction to be vacated without retrial, and the city paid Patterson $1.2M to settle his civil right claims. Arthur also volunteers with the nonprofit, Focused Athletics, helping inner city athletes earn admission to college and, with his wife, is an active supporter of college sports.

Arthur graduated from Temple University Beasley School of Law, magna cum laude, and the University of Pennsylvania, cum laude, where he was an offensive lineman on the football team. Arthur joined Cozen O’Connor following clerkships with District Court Judge Mitchell S. Goldberg and Magistrate Judge David R. Strawbridge, both of the U.S. District Court for the Eastern District of Pennsylvania.
