Consumers face a daily assault of flashy deals and marketing campaigns promising big savings. But not every advertisement tells the full story. So, to protect the public from misleading or deceptive practices, California has enacted  the False Advertising Law (FAL), designed to ensure that companies are honest in the way they promote goods and services.

Whether it is a misleading discount or a hidden limitation buried in fine print, businesses that cross the line can face legal consequences. Contact our consumer fraud lawyers to learn more.

What California Law Prohibits

California’s False Advertising Law makes it unlawful for a business to disseminate any statement that is untrue or likely to mislead. This includes advertisements published online, in print, on television, on billboards, and even on product packaging.

The standard is not whether the advertiser intended to deceive but whether the message would mislead a reasonable consumer. Examples include:

  • Claiming a product is “100% organic” when it is not certified as such.
  • Advertising “no fees” but adding unavoidable charges at checkout.
  • Suggesting a limited-time offer when the deal is ongoing indefinitely.
  • Comparing a product to a competitor’s in a way that distorts facts.

Because the statute is broad, nearly any communication used to promote a sale could be scrutinized.

In class action cases, the financial exposure for businesses can be substantial, as restitution may apply to thousands of consumers at once.

Proving a Violation

Courts typically look at whether a “reasonable consumer” would likely be deceived. Plaintiffs only need to show that a good portion of the targeted audience could have been misled.

Even technically true statements may be unlawful if they are presented in a way that creates a false impression. For example, a product advertised as “50% off” could still be misleading if the “original price” was inflated and rarely charged.

When companies distort the truth, they gain an unfair advantage over honest competitors and undermine consumer confidence. The FAL helps level the playing field by holding businesses accountable for the promises they make.

FAQs on California Consumer Rights

Do I have to prove the company intended to deceive me?
Under California law, the focus is on whether the advertisement would likely mislead a reasonable consumer, not whether the business acted in bad faith.

Can a group of consumers join together in a case?
Class actions are common in false advertising disputes, especially when the same misleading message reached thousands of people.

What if the ad was technically true but left out important details?
Omissions or half-truths can still be unlawful. Courts recognize that an incomplete message can be just as deceptive as an outright lie.

Are online businesses treated differently than brick-and-mortar stores?
The False Advertising Law applies broadly to digital and physical advertising alike.

How long do I have to bring a claim?
Deadlines vary depending on the statute invoked, but many false advertising claims must be filed within a few years of the incident. Consulting a consumer protection attorney early ensures you preserve your rights.
