The rapid development of technological innovations is transforming society at a global level in the 21st century. These technologies are changing the way we work, communicate, and entertain ourselves, and artificial intelligence (AI) is having an increasingly significant impact on the world. AI has the potential to transform many aspects of our lives, so it is important that it is used in a safe and responsible way. Legal regulations are essential for ensuring the responsible use of AI and for providing effective protection in case of damage caused by AI. The European Union has recently begun developing regulatory frameworks to ensure standards and norms for AI at the EU level. The Proposal of the Artificial Intelligence Act, which sets out standards that all EU member states must follow, together with the Proposal for a Directive on liability for defective products and the Proposal for an Artificial Intelligence Liability Directive completes the puzzle of the first legislative framework on liability for AI. These three acts, together with the General Product Safety Regulation, should provide adequate protection for victims in the event of damage caused by AI. The purpose of this thesis is to investigate how four key legal sources regulate liability at the EU level in the case of damage caused by AI and how these four sources can be implemented into Croatian law.
