Anonymity as the Enforcement Wall
What the Keller-Sutter complaint establishes is not that AI defamation is difficult to prosecute — it is that prosecution cannot begin when no human is identifiable as the proximate actor . Criminal defamation law was written for speakers. When the speaker is an AI model operating on an anonymous prompt, the legal architecture has no entry point. The complaint against "persons unknown" is not a strategic choice; it is the only available option under current Swiss law .
This is where AI malpractice anxiety meets a profession still building its policies — the parallel to AI-generated false citations admitted in Nevada County criminal briefs is exact: in both cases, the harm is documented, the mechanism is traceable, and the responsible party is legally indeterminate. Practitioners who assumed AI liability would be resolved in the courts before it reached them are already inside the vacuum the Swiss case makes visible.
