Aachen court makes it two: German judges keep holding Google liable for AI answers

A second German court has ruled that Google is liable for what its AI-generated search summaries say about people. The Aachen Regional Court applied the same legal reasoning as a landmark Munich ruling, this time in a case where Google's AI falsely attributed criminal offenses to a doctor who had nothing to do with them.

The decision matters far beyond one doctor's reputation. It signals that a consistent line of legal thinking is forming across Germany's courts — one that refuses to treat AI-generated answers as neutral pass-throughs of other people's content. Instead, judges are treating Google's AI Overviews as content the company itself published. And that distinction carries real weight for every search engine, AI assistant, and chatbot operating in one of Europe's largest markets.

How did we get here? A quick rewind

The story starts in Munich. A court there issued what observers described as a landmark ruling on AI search liability: Google, the court held, could be held responsible when its AI-generated search summaries made false claims about people. It was the first time a German court had drawn that line so explicitly for AI summaries in search.

Google responded the way large companies often do. It appealed. Then, according to reporting by The Decoder, it quietly settled the case. No dramatic courtroom finale. No appellate precedent that might have clarified — or softened — the Munich reasoning. Just a settlement, and presumably a hope that the whole issue would fade.

That strategy has now failed. The Aachen Regional Court, in a separate case with separate facts, reached substantially the same conclusion. Two courts. Two cases. One consistent legal view.

What does the Aachen ruling actually say?

The facts of the new case are stark. Google's AI Overviews attributed criminal offenses to a doctor. The offenses actually involved someone else — a different person entirely. The doctor, in other words, was falsely linked to crimes by an automated summary that millions of searchers might read and take at face value.

The Aachen Regional Court applied what The Decoder describes as "the exact same reasoning" as the Munich court. The core of that reasoning: Google's AI answers are the company's own content. Google doesn't get to position itself as a neutral conduit when its systems generate, synthesize, and present those statements directly to users.

That framing demolishes the defensive argument search engines have leaned on for decades. Traditional search results point users to third-party pages, and platforms have historically argued they merely index and link. AI Overviews are different. They produce text. They make claims. Under the emerging German view, when that text defames someone, the defamation is Google's.

Why does the Munich settlement matter now?

Google's quiet settlement in the Munich case looks, in hindsight, like a tactical misstep — or at least a bet that didn't pay off.

By settling rather than fighting the appeal through to a final judgment, Google avoided creating binding appellate precedent against itself. That's a standard move. The risk was always that other courts would simply adopt the Munich reasoning on their own, settlement or no settlement.

That's exactly what happened. The Aachen court didn't need the Munich case to be affirmed on appeal. It looked at the reasoning, found it persuasive, and applied it. A settlement can end one lawsuit. It cannot unwrite a legal argument that other judges can read.

The Decoder's reporting captures the dynamic plainly: "Google tried to overturn a landmark Munich ruling on AI search liability by appealing, then quietly settled. The strategy isn't working."

What's the legal principle at stake?

Strip away the case specifics and a single question sits at the center of this story: who speaks when an AI system speaks?

For years, the answer for search engines was: not us, we just link. That position rested largely on liability shields built for intermediaries — platforms that host, index, or transmit content created by others. The logic was coherent when a search result was ten blue links.

AI Overviews broke that model. The system reads the web, then composes its own answer in its own words, displayed prominently above the traditional results. Users see a statement, not a list of sources. German courts are now saying the legal responsibility follows that user experience: if Google writes the answer, Google answers for the answer.

As The Decoder reports, "a consistent legal view is forming across German courts, and it treats Google's AI answers as the company's own content."

Why should anyone outside Germany care?

Germany is the largest economy in the European Union and a bellwether for European tech regulation more broadly. Court-made doctrine there rarely stays confined. Plaintiffs' lawyers across the EU watch rulings like these closely, and legal reasoning that succeeds in one member state tends to travel — especially on questions of defamation, personality rights, and platform liability, where European legal traditions share common ground.

The stakes for Google are commercial, not just legal. AI Overviews sit at the top of the search results page. They are the product. If every hallucinated or defamatory statement in that product creates direct liability, the cost calculus of AI-generated search changes fundamentally. It's one thing to indemnify enterprise customers. It's another to face a parade of individual plaintiffs — doctors, business owners, private citizens — whose lives an AI summary mischaracterized.

And the pressure won't stay on Google alone. Any company whose AI produces public-facing statements about real people — chatbots, assistants, recommendation engines, agentic tools that summarize the web — faces the same underlying question the Aachen and Munich courts just answered.

What happens next?

Two rulings do not make final law. Germany's higher courts have not yet spoken, and Google still has procedural options, including appeals in the Aachen case. But the direction is clear and, for Google, unwelcome: lower courts are converging on the view that AI answers are the company's own content, and settling individual cases hasn't slowed that convergence.

The realistic paths forward narrow quickly. Google can fight this to Germany's highest courts and risk a definitive precedent. It can invest heavily in making AI Overviews refuse or hedge claims about private individuals. Or it can keep settling, case by case, while the doctrine hardens around it. Whichever route it picks, the era of treating AI-generated search answers as legally weightless text is ending — at least in Germany, where two courts have now said so in plain terms.
