A second German court has ruled that Google is directly responsible for false claims in its AI search answers — because those answers are Google’s own statements, not neutral search results. Why it matters: if that reasoning spreads, every AI answer engine carries publisher-style liability for what its model invents, which changes the economics of AI search.

What happened
In a decision dated September 24, 2026, the Aachen Regional Court barred Google from spreading certain false statements its “AI Mode” search feature generated about a local physician, and explicitly relied on the reasoning of an earlier Munich ruling. The Decoder reported on October 18 that Google’s publicly announced appeal of the Munich case was never carried through to a decision — the case ended in a settlement instead, so no higher court has tested the reasoning.
In late May, Munich Regional Court I had ruled that Google is directly liable for its AI-generated search summaries after its AI falsely linked two Munich-based publishers to fraud schemes. The judges classified AI Overviews as Google’s own statements, meaning the company itself has to answer for them.
The Aachen case: an AI pinned someone else’s crime on a doctor
The Aachen plaintiff worked as chief physician and professor of neuroradiology from 2010 until late June 2026. On August 28, a colleague told him Google’s AI Mode was explaining his departure with an alleged sexual assault against his secretary. Follow-up searches using terms like “suspension” and “court proceedings” produced detailed, multi-paragraph fabrications, including an invented legal aftermath.
None of it concerned him. The AI had taken events involving a different former university professor and attached them to the doctor — something the court could confirm from its own records, because the criminal case had been brought against someone else. The doctor asked Google by email in late August to remove the content; in mid-September Google said it would take no action, and a formal legal demand also went nowhere while the false texts stayed live.
The court then acted on an emergency basis without hearing Google first, banned further spread of the three disputed text variants, and set fines of up to 250,000 euros per violation. Google can still challenge the injunction, and the decision is not final.
Why it matters
Two regional courts have now converged on the same view: a company that “provides AI-generated search is therefore also responsible for the answers generated in this context,” as the Aachen court put it, noting that Google’s AI produces “independent, new, and substantive statements” from combining third-party sources. The court also said checking would have been feasible — had Google confronted its own AI with the doctor’s objections, the system would have caught the errors itself.
For anyone building on AI search, the stakes go beyond one person’s reputation. Settlements can keep individual cases from becoming binding precedent, but a pattern of courts treating AI answers as the provider’s own content raises the cost of every hallucinated claim — and, as The Decoder notes, could eventually support claims from the publishers whose work feeds those answers. Expect answer engines to get more cautious, and takedown processes to get faster, at least in Germany.
Frequently asked questions
Did a German court ban AI Mode or AI Overviews in Germany?
No. The Aachen order targets specific false texts about one person. It does not ban AI Mode, require Google to stop summarizing people, or decide damages.
Why is Google liable if the AI combined information from other websites?
Both courts reasoned that the AI’s answers are independent, new statements Google itself produces — not mere links or references to third-party content — so Google answers for them as its own content.
Is the Aachen ruling final?
No. It is an injunction Google can still challenge, and the earlier Munich case ended in a settlement rather than a higher-court decision.
