By attending this workshop, you will step in a fictional court case dealing with the liability of AI technology in cancer diagnosis. A group of patients sues an AI technology company for being wrongly treated for prostate cancer. The AI Act, AI Liability Directive and the new Product Liability Directive are in force. There is no evidence of doctors’ malpractice. The workshop participants are invited to support either the claimant or the defendant in arguing in favor or against the company being held liable. To convince the judge, participants will need to discuss whether causality can be established between the company’s technology actions and the patients’ damage. In particular, the company’s data governance and transparency measures are under scrutiny.
