A German court ruled that Google can be held liable for defamatory statements generated by the AI Overview that appears at the top of its search results.
What’s new: The Regional Court of Munich found that Google’s AI Overview generated false, reputation-damaging claims. The generated text said that two German publishers engaged in fraudulent business practices and lured unknowing customers into buying subscriptions. Because Google generated the AI Overview, the court ruled that the company was responsible for defamatory falsehoods it contained. The court issued a temporary injunction that requires Google to stop disseminating the statements.
How it works: When users searched for the German publishing house Verlagshaus24 or its subsidiary GeraMond followed by the word “scam” — a term suggested by Google's autocomplete function — AI Overview responded with a summary that stated, “Yes, [company] is known for dubious business practices.” It also listed characteristics of an alleged scam including subscription traps, poor customer service, and content that remained locked even to paying customers. The court determined that the publishers in question had not, in fact, been accused of misconduct. Instead, the AI Overview had confused them with other companies that were suspected of fraudulent practices. The court found Google’s legal defenses lacking and held it responsible for defamation, and it enjoined Google to remove the statements immediately or pay a fine.
- The court found that Google’s AI Overviews were “independent, new, and substantive statements” that combined and rewrote information from other sources. By presenting AI-generated text as its own speech, Google took on liability for false statements.
- Google argued that users are savvy enough not to trust AI blindly and can verify AI Overview responses. The court rejected these arguments. Although AI Overview cited its sources, they did not actually support the AI-generated assertions, the court noted.
- The court ordered Google to pay 80 percent of the litigation costs, while the two plaintiffs were responsible for 10 percent each. If Google violates the injunction by continuing to disseminate the false statements, it faces fines of up to $285,000. The court's injunction takes effect immediately.
- Google plans to appeal the ruling, Reuters reported. The case will move to the Federal Court of Justice, Germany’s final venue for judicial appeals.
Behind the news: German and EU law generally have treated search engines as information intermediaries that display content rather than create it. Thus, search engines have borne limited liability for unlawful information in their results — until now.
Why it matters: Munich’s ruling against Google is a landmark case that shifts search engines’ liability for false statements. In the near term, it could alter the way Google presents its AI Overview. In the longer term, if the ruling is upheld on appeal, it could encourage similar lawsuits in Europe and elsewhere. One analysis found inaccuracies in roughly 10 percent of Google AI Overview results. If this figure holds, Google and other AI providers could face significant risk of litigation.
We’re thinking: We think that agentic question-answering systems can be improved significantly — for example, by grounding them in more reliable information sources. We remain optimistic that such systems can continue to operate at scale.
