Cover Story: The rapid digitalization of judicial systems has made vast numbers of court decisions publicly available, yet their unstructured narrative form limits meaningful access. Judicial decisions interweave facts, arguments, and legal reasoning in complex ways, making structural understanding essential for scalable access to case law. This study presents the first in-production, sentence-level Rhetorical Role Labeling (RRL) system for Hungarian judicial decisions. Based on a newly curated, expert-annotated corpus, the work compares classical and neural architectures for identifying the functional roles of sentences in legal judgments. The deployed system now enables role-aware legal search across Hungary’s judicial decision database, significantly enhancing the transparency and usability of court decisions. View this paper
