In a ruling of May 28, 2026 (case 26 O 869/26), made public in early June 2026, the Munich I Regional Court (Landgericht München I) prohibited Google in summary proceedings from disseminating untrue factual claims about two Munich-based publishers in its AI Overview search function. The court classified Google not as an indirect distributor of third-party falsehoods but as a direct disturber (direct infringer) whose AI produces false information as Google's own content (Source: heise.de). It is the first reported German decision to prohibit specific false AI Overview statements on this basis (Source: the-decoder.com).
| Court | Landgericht München I (Munich I Regional Court), Germany |
| Case number | 26 O 869/26 |
| Ruling | May 28, 2026 (preliminary injunction, summary proceedings); public early June 2026 |
| Applicants | Two Munich-based publishers (represented by Lausen Rechtsanwälte) |
| Respondent | |
| Status | Injunction granted; Google bears about 80 percent of legal costs |
Background
Google's AI Overviews function generates a flowing summary text above conventional search results, synthesizing multiple sources into a single answer. In the conduct at issue, the AI Overview incorrectly attributed information about dubious dealings of other companies — reported as including links to scams and subscription traps — to the applicants' business (Source: heise.de). The publishers, represented by the law firm Lausen Rechtsanwälte, sought a preliminary injunction against the false statements.
Holding
The chamber's reasoning distinguishes the generative format from conventional search. While ordinary search results merely present indexed third-party content with title, snippet, and link, the AI Overview evaluates multiple sources and produces an independent, coherent answer that average users perceive as information from Google itself. The court held that the limited liability search engines have traditionally enjoyed for third-party content does not transfer to this generative format; ordinary defamation-law standards apply instead, and untrue factual claims can be prohibited without Google invoking the automated nature of the process. A "created with AI" notice does not change the attribution to Google (Source: heise.de).
Google must remove the objected content and prevent the function from generating comparable false claims about the affected publishers, on pain of court-imposed penalties. According to the industry service JUVE, Google bears around 80 percent of the legal costs of the proceedings (Source: heise.de).
Relation to earlier case law
The ruling builds on a September 2025 decision of the Frankfurt am Main Regional Court (case 2-06 O 271/25), which held that liability for AI Overviews is not per se excluded but rejected the specific cease-and-desist application before it. The Munich court went further by prohibiting specific false statements (Source: heise.de).
Reactions and commentary
Commentary has connected the ruling to the question of platform-liability immunity for AI-generated output. Gary Marcus argued the decision illustrates why Section 230-style immunity may not shield AI-generated content in the United States, since the summary is the platform's own speech rather than hosted third-party content (Source: garymarcus.substack.com). Coverage has also noted the ruling's operational consequences for the German-language market — incentives toward more conservative AI Overview output for sensitive topics such as individuals, companies, and health — and placed it alongside the UK Competition and Markets Authority's June 2026 conduct requirement on CMA oversight of Google's AI search functions, and announced complaints under the Digital Services Act (Source: heise.de).
Current status
The injunction issued in summary proceedings; the parties' names and the full decision text have not been identified in public reporting, and the judgment does not yet appear on a public canonical host. Whether Google has lodged an objection or appeal, or whether main proceedings will follow, is not reported as of June 12, 2026.
