Phillips & Cohen LLP specializes in representing whistleblowers in false claims (qui tam) cases under federal and state false claims laws and has the nation's most successful qui tam practice.

Qui tam cases brought by the firm's lawyers have generated civil and criminal recoveries to the federal government totaling more than $2.6 billion.

The firm's roster includes former government fraud prosecutors, a former U.S. Senate Judiciary counsel, a former U.S. Attorney and experienced litigators recruited from the nation's top law firms.

One of the firm's founding partners, John R. Phillips, was closely involved in helping Congress amend and strengthen the False Claims Act, a Civil War-era law, in the mid-1980s. He worked with Senator Charles Grassley, a Republican from Iowa, and Congressman Howard Berman, a Democrat from California, to make the False Claims Act a powerful tool to fight fraud against the government in modern times.

Phillips & Cohen handles lawsuits nationally. It has represented qui tam "relators" (whistleblowers) in 24 states in a wide range of government fraud cases, including defense contractor fraud, health care fraud (Medicare and Medicaid fraud) and fraud involving municipal bond transactions. The firm also handles cases brought under state false claims laws.

Phillips & Cohen investigates potential cases without a charge. It represents clients on a contingency basis, which means if the case is successful, the firm will share in the client's recovery. If a case is unsuccessful, no fees are charged.

The firm is experienced in working with counsel locally and is skilled at assembling multi-firm trial teams whenever additional and substantial litigation resources are required.

By having its main office in Washington, D.C., Phillips & Cohen is able to work more closely on its clients' cases with trial lawyers and officials at Justice Department's headquarters, where most of the case planning and decision-making occurs. The firm also has an office in San Francisco, California.
