The 22nd edition of the JURIX conference was held in Rotterdam on the 17th and 18th December and was hosted by the Erasmus University Rotterdam. While the conference was back to its country of origin, JURIX continues to attract a wide international audience. This year, the conference received submissions from all five continents. This clearly demonstrates the lively and growing interest for the highly interdisciplinary discipline of legal informatics. The selection of papers for this edition of JURIX covers a wide variety of topics in legal informatics, including contributions on established fields such as legal document management, argumentation, case based reasoning, dispute resolution, support for legal drafting and ontologies, to emerging areas such as regulatory compliance, normative multi-agent systems and game theory, as well as application areas, for example, fraud detection, legal tutoring systems and legal decision support systems.
