A False Claims Act case can be brought by a whistleblower (relator) to recover funds on behalf of the federal government. The government then has the option to “intervene” and proceed with the action. If the government does intervene, it has the primary role in prosecuting the action, although the relator remains entitled to a percentage of any recovery. Even if the government declines to intervene initially, it can later intervene upon a showing of “good cause.”
