The statute begins, in § 3729(a), by explaining the conduct that creates FCA liability. In very general terms, §§ 3729(a)(1)(A) and (B) set forth FCA liability for any person who knowingly submits a false claim to the government or causes another to submit a false claim to the government or knowingly makes a false record or statement to get a false claim paid by the government. Section 3729(a)(1)(G) is known as the reverse false claims section; it provides liability where one acts improperly – not to get money from the government, but to avoid having to pay money to the government. Section 3729(a)(1)(C) creates liability for those who conspire to violate the FCA.
A person does not violate the False Claims Act by simply submitting a false claim to the government. The person must submit the claim with knowledge of the falsity. Knowledge of false information is defined as being (1) actual knowledge, (2) deliberate ignorance of the truth or falsity of the information, or (3) reckless disregard of the truth or falsity of the information.
