Jarosław Łukomski voice deepfake — Nov 2026

The District Court in Warsaw has ruled that JFC Polska engaged in the unauthorized use of an AI-generated voice model resembling narrator Jarosław Łukomski in its advertising materials. The court determined that the synthetic audio constituted a deepfake, leading to orders for the company to remove the content, issue public apologies, and provide financial compensation to the claimant.

What happened

The case, heard by the Intellectual Property Division of the District Court in Warsaw, centered on JFC Polska’s creation and deployment of a digital voice model based on Łukomski’s likeness without his knowledge or consent. A court-appointed expert analyzed the audio and concluded that the synthetic voice was distinctly and misleadingly similar to Łukomski’s, capable of deceiving an average listener. Judge Sylwia Wit vel Wilk noted in the ruling that the advertisement functioned as a deepfake, as it created the impression that the narrator had spoken words he never actually uttered.

The court affirmed that a person's voice is a protected non-property right, regardless of their professional status. Consequently, JFC Polska was ordered to cease all use of the voice model and remove existing materials. The company must publish an apology on its website for 14 days, on its Facebook profile for 45 days, and within the publication Wirtualne Media. Additionally, the court awarded Łukomski 30,000 zlotys in compensation for non-pecuniary damage, plus over 17,000 zlotys in further compensation and legal costs. While the ruling is not yet final, JFC Polska representatives have indicated they are consulting on potential next steps.
