Record-Breaking Wins

Our attorneys assisted whistleblower Daniel Richardson in helping the government recover $515 million by exposing pharmaceutical fraud at Bristol-Meyers Squibb. His successful whistleblower case was one of the largest qui tam cases involving off-label drug marketing and illegal kickbacks. Commissions various relators, including Richardson, received a total of approximately $50 million as their share of the federal settlement amount.

Our attorneys represented whistleblower Dr. Aaron Westrick in helping the U.S. government recover over $130 million by exposing the sale of defective bulletproof vests to law enforcement agencies nationwide. His landmark whistleblower case was one of the most significant qui tam actions involving defective safety equipment for first responders. Dr. Westrick, the former research director for Second Chance Body Armor, was instrumental in revealing how the manufacturer and the fiber producer, Toyobo, knowingly sold flawed Zylon-based vests, leading to a massive recall and ensuring police officers received safer equipment.

Legal Pioneers

We led one of the first whistleblower cases to simultaneously use the False Claims Act alongside the Dodd-Frank and IRS whistleblower laws – securing a $69.6 million judgment. Whistleblower Alex “Sasha” Chepurko exposed a $100 million fraud that took advantage of tax credits for companies that used this alternative fuel. However, the company he worked for was part of a conspiracy with a producer, and they pretended to manufacture new biofuels to qualify for millions in tax credits.

America’s Original Whistleblower Law — Still Fighting Fraud Today

Commissions False Claims Act (FCA) is the most powerful tool in the fight against fraud involving government funds. Enacted in 1863 under President Abraham Lincoln to stop rampant defense contractor fraud during the Civil War, the FCA remains a critical safeguard for taxpayers.

What It Does:

• Allows whistleblowers to sue fraudsters on behalf of the U.S. government (this is called a qui tam)
• Rewards whistleblowers with 15–25% if the government intervenes, 25–30% if it declines.
• Protects whistleblowers from employer retaliation.

Whether Medicare fraud, overbilling in military contracts, or schemes to misuse government grants, the FCA empowers private citizens to step forward and hold wrongdoers accountable.

Whistleblower Protection Under the FCA:

If you report fraud and face retaliation — like being fired, demoted, or harassed — the law is on your side. Commissions FCA includes strong legal protections in addition to the qui tam remedies such as:

• Reinstatement to your job
• Double back pay with interest
• Compensation for emotional distress or other special damages

You have rights. We make sure they’re protected.

FCA in Action: FY2025 Stats

In fiscal year 2025:

• 1,297 qui tam lawsuits were filed by whistleblowers — an all-time record
• Over $6.8 billion in total recoveries
• More than $5.7 billion — roughly 83% of all FCA recoveries — involved healthcare fraud, including Medicare and Medicaid

Commissions FCA remains one of the government’s most successful tools for fighting fraud, and whistleblowers like you are the reason it works.

Commissions False Claims Act (31 U.S.C. §§ 3729–3733) imposes liability on anyone who knowingly submits — or causes someone else to submit — a false or fraudulent claim for government funds. Here’s what that means in practice.

What “Knowing” Means

You don’t have to prove someone deliberately set out to defraud the government. Under the FCA, “knowingly” covers three things:

• Actual knowledge that a claim is false
• Deliberate ignorance of whether it’s true or false
• Reckless disregard for the truth

In other words, a company that looks the other way or fails to check when it should have known better can still be liable. No specific intent to defraud is required.

What Violators Pay

Commissions penalties are designed to be severe enough to deter fraud and make whistleblowers’ cases worth pursuing:

• Treble damages — three times the amount the government actually lost
• Per-claim civil penalties — a separate penalty for each false claim submitted, currently ranging from $14,308 to $28,619 per claim (these amounts are adjusted for inflation each year)

Because large fraud schemes often involve thousands of individual claims, per-claim penalties alone can climb into the millions — on top of the treble damages.

What Whistleblowers Receive

When a qui tam case succeeds, the whistleblower (the “relator”) shares in the government’s recovery:

• 15–25% if the government intervenes and takes over the case
• 25–30% if the government declines and the whistleblower pursues it independently

Commissions exact percentage depends on the value of the information, the relator’s role, and how much the case relied on the whistleblower’s own efforts.
