Yes, potentially. California Business and Professions Code section 17500 makes it a misdemeanor to publicly disseminate an untrue or misleading factual statement to sell goods or services, or to induce someone to enter an obligation, when the person knew or with reasonable care should have known the statement was misleading. The statute does not state a completed purchase or buyer reliance as an element; that is an inference from its text, not a separate court ruling.

What facts matter

The question is more specific than whether an advertisement was inaccurate. Preserve the exact ad and its context: the words or images used, where and to whom it was shown, what product or service it promoted, who prepared or approved it, and what that person knew or should have known when it was disseminated.

Section 17500 applies to public dissemination, including online statements, and provides a misdemeanor penalty of up to six months in county jail, a fine up to $2,500, or both (Business and Professions Code section 17500). Whether the statement, audience, purpose, and speaker’s knowledge meet the statute depends on the actual facts. The reasonable-care language does not mean every mistaken statement is automatically criminal.

A separate public civil-enforcement route

The advertising chapter also allows specified public prosecutors to seek a civil penalty of up to $2,500 per violation under Business and Professions Code section 17536 (section 17536). That is a separate public civil-enforcement track. It does not mean a private consumer can collect that statutory penalty or that every criminal allegation automatically produces both proceedings.

This differs from a false-pretenses theft case, which turns on obtaining another person’s property through a false representation. A section 17500 inquiry can focus on the public advertisement and the speaker’s knowledge even where no buyer completed a purchase. The exact statement, its audience and purpose, and what the accused knew are central records to preserve.

Save the original ad, screenshots showing where it appeared, versions and approval records, and communications about the claim.
