Mary Inman

Partner, Constantine Cannon


Mary Inman is a partner in Constantine Cannon’s London Office.  After 20+ years representing whistleblowers in the U.S., she moved to London in July 2017 to launch the firm’s international whistleblower practice.  She specializes in representing whistleblowers from the U.K., Europe and worldwide under the various American whistleblower reward programs, including the Federal and various state False Claims Acts and the SEC, CFTC, IRS and DOT whistleblower programs.  Ms. Inman’s efforts to export the American whistleblower programs to the United Kingdom, including her efforts on behalf of British whistleblower Andrew Patrick, were featured in a recent New York Times article.

Ms. Inman is a recognized expert and frequent author and speaker on areas related to the international application of the American whistleblower laws, financial frauds, health care reimbursement and government procurement.  She has particular expertise in addressing Medicare Advantage risk adjustment fraud and is one of the lead counsel in a prominent whistleblower case against UnitedHealth Group involving allegations the Medicare Advantage Organization submitted false claims for payment to the Medicare Program based on artificially inflated member risk scores.  She also has extensive experience addressing fraud in the financial services industry, government infrastructure projects, and representing city and state governments in prosecuting civil fraud actions.

Ms. Inman joined Constantine Cannon in June 2015.  Previously, she was a partner at Phillips & Cohen, LLP.  Her clients have successfully helped the United States and various states and municipalities recover hundreds of millions of dollars, including cases where:

  • A British retailer of luxury cashmere sweaters and its CEO paid $900,000 to settle allegations that they had engaged in a practice of splitting packages to evade the payment of U.S. customs duties.
  • two Tampa, Florida based Medicare Advantage Organizations, Freedom Health and Optimum Healthcare, paid $32.5 million to settle allegations that they had fraudulently induced CMS to allow them to expand their health insurance offerings into new counties in Florida and the Carolinas by falsely representing that they had a sufficient network of doctors, clinics, and hospitals available to serve their enrollees in the expanded service area when they had no such networks in place.
  • A California jury awarded a $223 million verdict to several Los Angeles and California agencies against an electric utility for overcharging its government customers.
  • A series of hospitals around the country paid $62.9 million to settle allegations that they had inflated cost reports submitted to Medicare for reimbursement.
  • Tyco International and other manufacturers paid over $60 million to settle claims by dozens of California municipalities that they had sold waterworks parts with 40% more lead than allowed by industry standards.
  • Tenet Healthcare Corp. paid $9.75 million in part to settle allegations that its subsidiary shifted costs from its inpatient unit to its rehabilitation unit to increase Medicare reimbursement.
  • Afghanistan war-zone contractor RECON International settled with the Department of Justice in 2010 to avoid litigating claims that it had fraudulently inflated its bills for materials used to build operating bases for U.S. troops.
  • The San Francisco Unified School District received a $5 million award after suing NEC Business Network Solution for paying kickbacks to school officials to induce them to order excess computer equipment using federal funds from the E-rate program.
  • Inman also was a leading member of the team of lawyers representing a whistleblower, several states and dozens of public agencies in a two-month jury trial, which resulted in a verdict that the largest PVC pipe manufacturer in the world had defrauded its customers over a ten-year period. Prior to the start of the trial, co-defendant Formosa Plastics paid $22.5 million to settle its own potential liability.

Ms. Inman graduated cum laude from the University of Pennsylvania Law School in 1994, where she was an articles editor and an associate editor of the University of Pennsylvania Law Review.
After law school, she clerked for the Honorable D. Brock Hornby, U.S. District Court for the District of Maine, and the Honorable Norman H. Stahl of the U.S. First Circuit Court of Appeals. She was then an associate at O’Melveny & Meyers LLP in San Francisco, where her practice focused on employment, collective bargaining and False Claims Act matters.

Ms. Inman graduated summa cum laude from Bowdoin College in 1990 with a joint degree in Russian and Government and Legal Studies.  During her senior year she studied abroad at the Moscow State Linguistic University.

Ms. Inman is bar-qualified in California and Maine.
