Expert: Monika Simmler, Professor of criminal law, Switzerland Swiss Finance Minister Karin Keller-Sutter filed a criminal complaint over a Grok post that an anonymous X user generated by asking the chatbot to "roast" her. According to Bloomberg, the complaint seeks to hold the X user accountable for defamation and verbal abuse, and separately asks the prosecutor to assess whether X also bears responsibility for failing to block Grok's misogynistic and "vulgar" output. The finance ministry described the result as a "blatant denigration of a woman" and said "such misogyny must not be seen as normal or acceptable." The user deleted the prompt within two days of Grok generating the response and said no harm was intended, describing it as a "technical exercise" to see whether Grok would roast the Swiss official. That defence is itself the shape of the failure: nobody set out to defame anyone - they were testing a feature, and the feature complied. xAI built and promoted that feature. Elon Musk has encouraged X users to prompt Grok for roasts since the chatbot launched, and an xAI spokesperson recently told Fox News that Grok is the only "non-woke" chatbot on the market. A model tuned to produce abuse on request will produce abuse about real, named people, and Grok's recent record is consistent with that design choice: it has generated antisemitic output since the "woke" filters were removed in July 2025, and its "undressing" image feature has already drawn bans, a Dutch court fine and a lawsuit from the city of Baltimore. The roast post is not a hallucination in the strict sense - no false fact was asserted - but it is the same class of failure. The system was handed a request to generate damaging content about a specific serving official and produced it instantly, with no editorial process between generation and publication and no check on whether the target had done anything at all. The live legal question is where liability lands. Swiss law threatens up to three years of imprisonment or a fine for anyone found responsible for the intentional publication of offensive material, and insults that damage a person's reputation also carry fines, reduced if they are retracted. Monika Simmler, a professor of criminal law, told Swiss media that "there is a good chance of prosecuting the authors of such prompts, even if the posts are subsequently deleted" - she did not opine on the risk to X or xAI. Keller-Sutter is pressing that question anyway: prosecutors have been asked to investigate whether X owed a duty of care to prevent Grok from generating such posts, or whether X "made Grok available with the knowledge or even intent that the technology could be used to commit criminal offenses." Lawyers writing for Bloomberg Law have noted that UK and EU law "leave room" for claims that automated systems cause reputational harm, and expect defamation rules to be widened to cover chatbot output. Switzerland is not in the EU - so if this complaint fails, the country may rewrite its law instead.
