German court holds Google liable for false statements in AI Overviews
The Regional Court of Munich issued a temporary injunction against Google after its AI tool conflated two publishers and invented facts about dubious business practices, a decision Google is likely to appeal.
A German court has issued a preliminary ruling holding Google liable for false and defamatory statements generated by its AI Overview tool, marking a significant shift in how algorithmic outputs are treated under liability frameworks. The Regional Court of Munich determined that AI summaries constitute independent, new, and substantive statements created by the company, rather than neutral links to third-party content. This classification denies Google the traditional search engine liability protections that have historically shielded operators from responsibility for indexed material.
The legal action stemmed from a case involving two Munich-based publishers whose reputations were allegedly damaged when the AI tool conflated separate entities. The algorithm invented facts about one entity being involved in scams and dubious business practices, making affirmative statements such as being "known for dubious business practices and is often perceived as a scam." These claims did not appear in the original search results or the cited sources, and Google failed to correct the misleading output despite receiving a cease-and-desist letter earlier this year.
In its defence, Google argued that users understand AI outputs are not always accurate and must be verified. The court rejected this, noting that the false statements in this instance were not present in the standard search results at all. The ruling emphasised that while surfacing third-party content is largely unavoidable for traditional search engines, AI Overviews provide an "additional function" that is not essential for internet use. The court stated plainly that "nobody needs AI to search the Internet," allowing users to find information without the tool.
The decision also weighed Google’s commercial speech rights against the publishers’ interest in removing false information. The court concluded that the publishers’ interest outweighed Google’s rights, particularly because the false outputs were primarily an expression of commercial activity capable of impacting public opinion. The court noted that Google’s argument regarding user verification was weak, as the tool’s utility would be diminished if users had to independently verify every displayed link, a behaviour that surveys suggest is not common among users.
Google stated it is reviewing the decision and is likely to appeal the preliminary ruling. The company’s spokesperson told Ars Technica that it invests deeply in the quality of AI Overviews to ensure responses are accurate and reflect information existing on the web. However, the ruling suggests that if other courts adopt this stance, major AI firms could face a wave of lawsuits over defamatory outputs generated during the current experimental phase of AI search technology.
