Casey has particular expertise in civil investigations involving alleged violations of federal fraud statutes and analogous state laws.
Casey returned to private practice in 2020 after serving as an Assistant United States Attorney in the Civil Division of the U.S. Attorney’s Office for the Southern District of New York, where he investigated allegations of fraud committed against the United States under the False Claims Act, Anti-Kickback Statute, and other laws. Casey also represented federal agencies and officers in a wide variety of affirmative and defensive matters, including cases involving constitutional law, the Administrative Procedure Act, bankruptcy, employment discrimination, the Freedom of Information Act, and trademark law.
