German Court Rules Google Liable for False Statements from AI Overviews

A local court in Germany has issued a ruling that could reshape the operation of search engines and AI-based chatbots worldwide. The Munich Regional Court preliminarily ruled that Google is liable for a series of false statements generated by its AI Overviews feature, requiring the company to prevent the dissemination of erroneous or inaccurate claims through its search engine.

The ruling stems from a case first reported by the Decoder, in which two publishers discovered that Google’s AI-generated summaries linked them, in certain searches, to questionable business practices, scams, and subscription-related frauds, without any basis for doing so. Earlier this year, the affected companies sent the tech giant a cease-and-desist letter. Google denied liability, arguing that its automatic summary feature warns users that the information may contain errors and should be independently verified.

The court’s analysis concluded that Google’s AI combined information corresponding to other companies that had been flagged for possible illicit practices with data from the plaintiffs, generating associations that did not appear in any of the sources linked by the search engine. The authorities found that, unlike traditional search engines, which merely display lists of links with statements made by third parties, Google’s tool produced “independent, new, and substantial statements” based on a misinterpretation of information available on the internet.

According to the court, correcting misinformation is not the responsibility of third parties. Google is the only entity with the ability to modify the technology underpinning its AI-generated summaries and, therefore, “must be held accountable.” Furthermore, the court found that Google’s line of defense lacked merit, since the challenged summary “contains statements that do not appear at all in the search results.”

The court also held that results generated by an AI system cannot be protected under the principles of free speech, as they are the product of an algorithm designed, trained, and managed by a company, and not the expression of an individual opinion.

As a precautionary measure to prevent possible recurrence, the ruling required Google to remove a large portion of the statements deemed defamatory in this case, and to cover 80 percent of the legal costs arising from the proceedings. A company spokesperson suggested that the decision could be appealed, stating that Google invests deeply in the quality of AI Overviews and that the decision is not yet final.

The German court’s ruling could have global repercussions for the artificial intelligence industry. Companies such as OpenAI, Anthropic, and Perplexity AI also warn their users that their AI systems may produce errors, but this case argues that such warnings are not sufficient to exempt developers from liability. The ruling holds that when an AI generates new statements not found in original sources, the company that designs, trains, and operates the system must assume legal liability for any damages caused.
