The California False Claims Act is the state statute, codified at Government Code sections 12650 through 12656, that penalizes fraud against state and local government programs with treble damages and civil penalties on every false claim, and lets private individuals sue on the government’s behalf for a share of what gets recovered.1Government Code sections 12650–12656 It applies to anyone who bills a public agency, handles public money or property, or owes money back to the government, and its enforcement runs largely on insider tips.
Conduct That Creates Liability
Government Code 12651(a) lists eight categories of prohibited conduct.2Government Code 12651(a) You can face liability for:
- Submitting a request for payment or approval based on false or fraudulent information.
- Making or using a fabricated record or statement that matters to a fraudulent claim.
- Conspiring with someone else to commit any of these violations, even if you never submit a claim yourself.
- Having custody of government property or money and knowingly delivering less than the full amount.
- Certifying receipt of government property when the certification misrepresents what was actually delivered.
- Knowingly buying or taking as collateral government property from someone with no authority to sell or pledge it.
- Using a false record to reduce what you owe the government, or concealing an obligation to pay or return money to a public agency.
- Receiving government funds through an inadvertent false claim, later discovering the error, and failing to report it within a reasonable time.
That last category catches people who had nothing to do with the original fraud. If your organization receives a government overpayment by mistake and you learn about it but keep quiet, the silence itself creates liability.
You Don’t Need Intent to Defraud
The statute does not require proof that you set out to cheat the government. Government Code 12650(b)(3) defines “knowingly” to cover three levels of awareness: actual knowledge that information is false, deliberate ignorance of whether it’s true or false, and reckless disregard for the truth.3Government Code 12650(b)(3) Turning a blind eye to red flags, or failing to verify the accuracy of a claim before submitting it, is enough.
California courts have read this broadly. A contractor who bills a public agency impliedly certifies that it is complying with its contract, so billing for services while violating the contract’s terms can itself be a false claim, even without an explicit lie on the invoice.4San Francisco Unified School District ex rel. Contreras v. Laidlaw Transit, Inc. (2010)
What a Violation Costs
Three layers of financial liability stack on top of each other:
- Treble damages: three times the actual dollar amount the government lost because of the fraud.2Government Code 12651(a)
- A civil penalty on each false claim. The statute sets a base range of $5,500 to $11,000 per claim, adjusted upward every year for inflation under the Federal Civil Penalties Inflation Adjustment Act. Current penalties are significantly higher than the base amounts.
- The government’s litigation costs, including attorney’s fees and investigative expenses.
The per-claim math is what drives judgments into eight figures. A company that submitted 500 fraudulent invoices faces penalties calculated on each one, not a single lump sum, on top of treble damages on the underlying loss.
The Reduction for Self-Reporting
Government Code 12651(b) lets a court cut the multiplier to between two and three times actual damages and drop the per-claim penalty entirely, but only if every one of these conditions is met:5Government Code 12651(b)
- You reported the violation to the responsible government officials within 30 days of discovering it.
- You fully cooperated with the government’s investigation.
- You provided all information known to you about the violation.
- No criminal prosecution, civil action, or administrative action had already started, and you had no knowledge of any investigation into the violation.
Wait for the government to come knocking and this option is off the table.
Suing on the Government’s Behalf
The qui tam provisions in Government Code 12652(c) let any person file a fraud lawsuit on behalf of the state or a local government.6Government Code 12652(c) The person who files is called a qui tam plaintiff, or relator. Most CFCA investigations begin this way.
How the Case Starts
The complaint is filed in camera in superior court and stays under seal for up to 60 days. The defendant isn’t served and typically doesn’t know the case exists. On the day you file, you must send the Attorney General a copy of the complaint along with substantially all material evidence and information in your possession.
The Attorney General then has 60 days to decide whether to intervene, though the AG can get extensions for good cause and courts routinely grant them in complex cases. The seal stays in place until the AG and any local prosecutors involved tell the court what they’ve decided.
If the government intervenes, it takes over primary responsibility for the litigation, and you remain a party. If the government declines, you can continue the lawsuit on your own. California does not force dismissal when the government passes, so a whistleblower can pursue even a large case independently.
The Whistleblower’s Share
If the case produces a recovery, you receive a percentage of the total proceeds, including both penalties and damages:
- If the government intervened: between 15% and 33%, depending on how much you contributed to prosecuting the case.
- If the government declined and you prosecuted on your own: between 25% and 50%, with the court setting the exact figure.
Reasonable attorney’s fees and litigation costs are awarded on top of the percentage, not taken out of it.
When a Public-Disclosure Case Gets Thrown Out
Not every tip supports a qui tam suit. Government Code 12652(d)(3) requires the court to dismiss a case if substantially the same fraud was already publicly disclosed through a government-related court or administrative proceeding, a legislative report, hearing, audit, or investigation, or the news media.7Government Code 12652(d)(3) The purpose is to keep people from reading about fraud and racing to the courthouse to collect a bounty.
Two exceptions keep a case alive. The Attorney General or a local prosecutor can oppose dismissal. And you qualify as an “original source” if you either voluntarily disclosed the information to the government before it became public, or your knowledge is independent of and materially adds to the public disclosures and you voluntarily gave it to the government before filing. First-hand knowledge of the fraud generally keeps you clear of the bar.
Protection From Retaliation
Government Code 12653 prohibits employers from retaliating against anyone who takes lawful steps to investigate, report, or help prosecute a CFCA violation.8Government Code 12653 The protection reaches employees, contractors, and agents, and it covers firing, demotion, suspension, threats, harassment, or any other adverse change in the terms of employment.
If you’re retaliated against, you can sue for:
- Reinstatement with the seniority you would have had.
- Two times back pay, plus interest on the lost wages.
- Special damages for other losses caused by the retaliation.
- Punitive damages where appropriate.
- Attorney’s fees and litigation costs, paid by the defendant.
The statute protects “lawful acts done in furtherance of” a CFCA action or “other efforts to stop” a violation. That language is intentionally broad: reporting suspected fraud, gathering evidence, cooperating with investigators, and testifying all qualify. The protection still applies even if it later turns out no fraud actually occurred, as long as you acted lawfully and in good faith.
How Long the Government Has to Sue
Government Code 12654 sets two alternative deadlines, and whichever expires later controls:9Government Code 12654
- Six years from the date the violation was committed, or
- Three years from the date the Attorney General or responsible prosecutor knew or reasonably should have known the material facts, with an absolute cap of ten years from the violation.
In most cases the six-year clock applies. The three-year discovery rule matters when fraud was concealed well enough that the government had no reasonable way to find it within six years. The ten-year cap is absolute: no matter how skillfully the fraud was hidden, the window closes a decade after it happened.
Overlap With the Federal False Claims Act
The CFCA closely mirrors the federal False Claims Act at 31 U.S.C. §§ 3729–3733, and the two laws frequently apply to the same conduct when fraud touches programs funded by both state and federal dollars.1031 U.S.C. §§ 3729–3733 Medi-Cal is the common example: the federal government and California split the cost, so a provider who inflates claims may violate both statutes at once. A whistleblower in that situation can file parallel qui tam actions under each law.
