The present dissertation has as its object the study of civil liability arising from unfair damage caused by artificial intelligence systems. Technology based on artificial intelligence has become one of the main tools for the development of mankind. Its disruptive power, capable of influencing people s daily lives and changing the way society relates to each other, reminds us of the emergence of the Fourth Industrial Revolution. Recent experience shows us that the performance of artificial intelligence is not always beneficial to its users. There are many cases of mistaken decisions or systems with biased algorithms that generate harmful consequences to their users, both financial and moral. In light of this reality and the peculiarities inherent in artificial intelligence systems, a debate has arisen in Brazil about the possible need for new laws to regulate civil liability for damages caused by artificial intelligence. Thus, the paper starts by analyzing some of the civil liability legal frameworks relevant to the regulation of artificial intelligence, such as the Civil Code, the Consumer Protection Code, and the General Law of Data Protection, to verify whether the existing legal framework is sufficient to regulate the matter. To this end, the main legal and ethical principles applied to artificial intelligence were also analyzed, as well as the treatment given to the subject by the European Union. Finally, possible complementary solutions to the civil liability of artificial intelligence were analyzed with the use of insurance, compensation funds and earmarked assets to ensure the unjust damage repair and reduce the risk of agents involved with artificial intelligence systems.
