Accurate Facts Can Still Produce A False AI Answer, And Courts Are Starting To Hold The Platform Responsible
Courts are starting to hold platforms responsible when AI answers built from accurate facts mislead, which could change how answer engines choose and combine sources.

A clean source list no longer makes an AI answer safe, and two German courts say Google owns what AI Mode says
Search Engine Journal reports that the Regional Court of Aachen, in a September 2026 decision, ordered Google to stop spreading versions of an AI Mode answer about a local doctor. He had been chief physician and professor of neuroradiology until late June. Searches about why he left returned a serious criminal allegation. Follow-up queries about suspension, termination and court proceedings produced longer accounts of a legal aftermath. The proceedings were real, but they involved a different former university professor. The doctor sent Google a detailed explanation in late August, and Google said in mid-September that it would take no action. The court then acted on an emergency basis without hearing Google, with fines of up to 250,000 euros per violation. Google can still challenge the order.
Does linking to sources protect the platform?
Not in Munich or Aachen. Both courts rejected the argument that users can check the cited pages themselves, and treated the AI answer as a self-contained statement made by Google.
Munich ruled in May that Google was directly liable for AI Overviews that tied two publishers to fraud and subscription traps. The claims appeared in none of the linked sources. That court described the output as "independent, new, and substantive statements", and Aachen adopted the wording. Both rulings say the answer, not the source list, is what carries liability.
Is the law actually settled?
No. A Berlin court reached the opposite view in early June, and no higher court has ruled because the one case heading there ended in a settlement.
The Berlin case was a trademark dispute. A perfume company objected to AI Overviews that named its brands next to links to cheaper imitations. The court called the feature a new format of search result and found no infringement. That summary repeated what other sites said, whereas the Munich and Aachen answers invented connections. The facts differ, but courts in one country have still described one product in incompatible ways. Google announced an appeal of the Munich ruling and then settled, according to The Decoder, as cited by Search Engine Journal.
Be sceptical about how far this reaches. The Aachen order is an emergency measure issued without Google's side. It is also German, and the coverage offers nothing on courts elsewhere.
How does a true fact end up attached to the wrong name?
Retrieval matches documents on a name and on surrounding attributes. When two people overlap, the system can merge them into one story, and every sentence in it still traces to a real document.
In Aachen the overlap was that both men were former university professors. This is the angle the headline coverage underplays. A review that checks each claim against its source would pass an answer like this one. The error sits in the join between facts, so the usual accuracy check cannot catch it. We have written about whether AI systems put your brand on the shortlist. Being merged with a namesake is a separate risk, and mention counts do not measure it.
What should I ask my AI-visibility vendor?
Ask whether the tool tests for entity conflation, meaning wrong attachments of true facts, or only counts mentions and citations. Ask who defines its "accuracy" score and how it was measured.
Ask how it handles follow-up queries. In Aachen the damaging text appeared when users added terms like termination and court proceedings, so a single-prompt audit would have missed it. Keep dated records of every report you send a platform. Google answered the doctor's detailed explanation by declining to act, and the court record of that refusal helped him.
Frequently asked questions
Can Google overturn the Aachen order?
Yes. The court acted without hearing Google, and Google can still challenge the order.
Does this cover only AI Overviews?
No. The Aachen case concerned AI Mode and the Munich case concerned AI Overviews.
Does it apply outside Germany?
The coverage gives no basis for saying so. It says the rules differ by jurisdiction and even by courtroom.
