AUTHOR=Rotolo Antonino , Sartor Giovanni TITLE=Argumentation and explanation in the law JOURNAL=Frontiers in Artificial Intelligence VOLUME=Volume 6 - 2023 YEAR=2023 URL=https://www.frontiersin.org/journals/artificial-intelligence/articles/10.3389/frai.2023.1130559 DOI=10.3389/frai.2023.1130559 ISSN=2624-8212 ABSTRACT=This article investigates the conceptual connection between argumentation and explanation in the law and provides a formal account of it. The contribution is twofold. On the one hand, we offer a critical reconstruction of the concept of legal argument, justification and explanation of decision-making as it has been elaborated in legal theory and, above all, in AI & Law. On the other hand, we propose some definitions of explanation in the context of formal legal argumentation, showing a connection between formal justification and explanation.
