California enforces some of the strictest consumer protection laws in the U.S.
According to Business & Professions Code 17500 BPC, it is both a criminal offense and a civil violation for any individual or company to conduct false, deceptive, or misleading advertising.
The statute prohibits making false statements about the nature, quality, price, or availability of real estate, personal property, or professional services, whether online, in print, or through broadcast media.
A single misleading marketing campaign can lead to serious criminal charges, class-action lawsuits, and enforcement actions by the California Attorney General or local District Attorneys.
If your business or marketing agency is under investigation for false advertising in Southern California, Cron, Israels & Stark offers proactive support to safeguard your operations.

What the Prosecution Must Prove to Convict
To establish a misdemeanor conviction under BPC 17500, California prosecutors need to demonstrate three key elements of the offense beyond a reasonable doubt.
-
Intent to Sell or Distribute: You created, published, or shared an advertisement to attract the public to purchase a product, rent property, or hire your professional services.
-
Misleading Statement: The advertisement included a claim, statement, or depiction about the property or service that was false, misleading, or structurally deceptive.
-
Knowledge or Negligence: You either knew or should have known through reasonable care that the advertising statement was false or misleading.
The "Should Have Known" Negligence Standard
Unlike many criminal statutes that demand proof of specific intent to commit fraud, BPC 17500 uses a negligence standard.
A business owner cannot just claim ignorance of an inaccurate ad. If a reasonable business owner would have verified the claims beforehand, failing to do so results in both criminal and civil liability.
The Statutory Language: BPC 17500
The text of Business and Professions Code Section 17500 states:
"It is unlawful for any person, firm, corporation or association... to make or disseminate or cause to be made or disseminated before the public in this state... any statement, concerning such real or personal property or services... which is untrue or misleading, and which is known, or which by the exercise of reasonable care should be known, to be untrue or misleading..."
Common Categories & Real-World Examples of Deceptive Marketing
False advertising appears in various forms in both digital and retail environments. Regulatory agencies monitor several common marketing tactics very carefully.
1. Bait-and-Switch Tactics
Advertising an extremely low price on an item without any real intention of selling it, just to attract consumers into a store or website, and then strongly urging them to buy a more expensive item because the original product is "unavailable."
2. Fake "Original Price" or MSRP Discounts
Labeling a retail product with a permanent "50% off" tag when it has never been sold at the claimed full retail price is misleading. According to California law, a business cannot advertise a previous price unless it was the dominant market rate in the last three months.
3. Falsifying Product Origins or Health Benefits
Labeling a product as "100% Organic" or "Made in the USA" when its raw ingredients are chemically treated or imported from abroad, as well as claiming a dietary supplement can treat or cure an illness without scientific verification, violates BPC 17500.
Real-World Defense Scenarios
Example 1: The Weight Loss Miracle (Criminal/Civil Liability)
An online e-commerce brand launches an Instagram ad claiming its proprietary herbal tea burns 15 pounds of belly fat in 7 days without diet or exercise.
However, the brand lacks scientific laboratory data or clinical studies to back this claim. Since the business owners knew or should have known the statement was biologically unsupported, they face potential prosecution under BPC 17500.
Example 2: Permissible Sales "Puffery" (No Violation)
A local pizza shop displays a large banner that says: "The Best Slice of Pizza in Los Angeles!" A competitor attempts to report them to the City Attorney for false advertising, arguing there is no official city ranking. However, this is not a crime. The law considers this kind of claim as puffery—an exaggerated, subjective opinion that reasonable consumers would not interpret as a factual statement.
Example 3: The Unintentional Inventory Sync Failure (The Accident Defense)
An electronics retailer advertises a high-end camera at a steep discount online. Unexpected server lag causes the system to sell out quickly, but the ad remains active for four hours, attracting angry consumers to the store.
The owner provides documentation showing that a technical glitch caused the delay and offers rainchecks to affected shoppers. Since there was no deliberate misconduct, criminal liability under BPC 17500 is avoided.
Penalties and Enforcement Actions
California considers false advertising a major threat to fair competition, with violations handled through two distinct legal avenues.
Criminal Misdemeanor Penalties
If a local prosecutor brings criminal misdemeanor charges against an individual or business officer, a conviction results in:
-
Up to 6 months in a county jail per separate violation.
-
Fines of up to $2,500 per violation.
-
Summary probation and mandatory court-ordered restitution to all defrauded buyers.
Civil Enforcement & Class Actions
Typically, the California Attorney General, a county District Attorney, or a city attorney initiate a civil enforcement action under BPC 17500 in conjunction with Unfair Competition Laws (BPC 17200). The court has the authority to order:
-
Civil Penalties: Each person who views or receives the deceptive ad can be fined up to $2,500. For large digital ad campaigns, these fines can total in the millions of dollars.
-
Restitution: Compelling the corporation to return all profits and provide full refunds to all impacted consumers..
-
Injunctions: A permanent court order requiring the business to delete its website, stop marketing activities, or fully overhaul its corporate identity.
Related Offenses Under California Law
-
Unfair Competition — BPC 17200: Broadly prohibits any unlawful, unfair, or fraudulent business act. False advertising under BPC 17500 is automatically treated as an act of unfair competition, doubling the civil exposure.
-
Selling a False Quantity — BPC 12024: Criminalizes the act of selling a physical commodity in a smaller weight, count, or volume than what was represented to the buyer.
-
Misrepresentation of Charges — BPC 12024.1: Makes it a misdemeanor to intentionally pad invoices or falsify service costs billed on the basis of time, weight, or count.
-
Grand Theft by False Pretenses — PC 487: If a highly coordinated false advertising scheme intentionally scams a consumer out of money or property valued at more than $950, the state can upgrade the case to a felony grand theft charge, punishable by up to 3 years in state prison.
Proven Defense Strategies Against False Advertising Claims
To effectively counter regulatory investigations or consumer fraud complaints, prompt and expert action is essential. A capable defense firm can employ multiple proven strategies:
The Defense of Substantive Puffery
If a marketing campaign uses vague, broad, or highly subjective praise (like "the most comfortable shoes on Earth"), your attorney can claim it as legally protected puffery. Since it doesn't include measurable data, a typical consumer wouldn't consider it a factual guarantee.
Scientific Substantiation & Data Verification
If your business is undergoing an enforcement check regarding an ingredients list or product performance claim, our firm can provide independent lab reports, third-party quality certifications, or documented industry data to verify that the claims were accurate at the time of publication.
Good Faith Reliance on Manufacturer Specifications
If you are a third-party retailer or drop-shipper who based your ad copy on technical spec sheets from the manufacturer, your attorney can argue that you exercised reasonable care and had no scientific way of knowing the supplier's data was incorrect.
Frequently Asked Questions (FAQs)
What is the legal definition of "puffery" in California advertising law?
Puffery refers to promotional language or marketing images that depend on subjective opinions, hyperbole, or exaggerations that no reasonable person would interpret literally.
For example, phrases such as "The Coolest Clothes in Town" or "World's Best Coffee" are considered safe from BPC 17500 prosecution because they cannot be objectively verified as true or false.
Can an ad be illegal under BPC 17500 even if the text is 100% factually true?
Yes. California courts evaluate the overall impression of an advertisement. Even if an ad presents factually accurate statistics, using misleading graphics, tiny, hard-to-read disclaimers, or deceptive formatting to deliberately mislead consumers into false conclusions is still deemed illegal false advertising.
Are digital influencers or marketing agencies liable for false advertising?
Yes. Under BPC 17500, anyone who "disseminates or causes to be disseminated" a false statement can be held liable. If an influencer or creative ad agency creates or portrays a deceptive review while knowing the claims are false, they can be named as co-defendants along with the brand owner.
How does a corporate defense attorney stop a BPC 17500 investigation?
