A federal judge has temporarily blocked California’s new law aimed at curbing the use of deepfake technology in political campaigns, citing First Amendment concerns. The legislation, known as Assembly Bill 2839, was signed into law by Governor Gavin Newsom in September 2024 and sought to prohibit the distribution of “materially deceptive audio or visual media of a candidate” within 120 days before an election, unless the content was clearly labeled as manipulated.
U.S. District Judge John A. Mendez granted a preliminary injunction against the law, stating that while the risks posed by artificial intelligence and deepfakes are significant, the statute likely violates constitutional free speech protections. He described the law as “a blunt tool that hinders humorous expression and unconstitutionally stifles the free and unfettered exchange of ideas which is so vital to American democratic debate.” ([latimes.com](https://www.latimes.com/california/story/2024-10-03/judge-blocks-california-law-that-targeted-deepfake-campaign-ads?utm_source=openai))
The legal challenge was initiated by Christopher Kohls, a conservative commentator known as “Mr. Reagan” on social media platform X (formerly Twitter). Kohls had produced an AI-generated parody video of Vice President Kamala Harris, which was shared by X owner Elon Musk. The video depicted Harris making statements she did not actually make, leading to a public exchange between Musk and Governor Newsom. In response to the ruling, Musk commented, “California’s unconstitutional law infringing on your freedom of speech has been blocked by the court. Yay!” ([politico.com](https://www.politico.com/news/2024/10/02/california-law-block-political-deepfakes-00182277?utm_source=openai))
Governor Newsom’s office defended the legislation, emphasizing its intent to protect the integrity of elections. Spokesperson Izzy Gardon stated, “Deepfakes threaten the integrity of our elections, and these new laws protect our democracy while preserving free speech. Satire remains alive and well in California — even for those who miss the punchline.” ([cbsnews.com](https://www.cbsnews.com/sanfrancisco/news/california-election-deepfake-law-ab2839-blocked-by-judge/?utm_source=openai))
Legal experts have weighed in on the ruling, noting the challenges in regulating deepfake technology without infringing on constitutional rights. Jeff Kosseff, a First Amendment scholar, remarked, “The California law is a clear violation of the First Amendment, so it is not surprising that Judge Mendez quickly blocked it. The opinion is a well-reasoned application of First Amendment law and recognizes that government regulation is not an appropriate solution to any challenges that might arise from deepfakes.” ([arstechnica.com](https://arstechnica.com/tech-policy/2024/10/ai-doesnt-abolish-right-to-roast-govt-judge-blocking-calif-deepfake-law-says/?utm_source=openai))
The court’s decision underscores the ongoing tension between combating misinformation through emerging technologies and upholding free speech rights. As deepfake technology becomes more sophisticated, lawmakers and courts will continue to grapple with finding a balance that protects both the integrity of elections and constitutional freedoms.
