Legal Tech is but the latest in a long line of shapes taken by the cooperation between Law and Computer/Information Sciences. The first organized attempt started in 1949, when Lee Loevinger founded Jurimetrics, in today's parlance Computational Legal Studies, the application of quantitative methods, and often especially probability and statistics, to law. In the early 1960s, the field of Legal Cybernetics emerged, first in Eastern Europe, in the late 1960s also in the West, especially in Germany and Italy. Legal Cybernetics had a much broader approach: law was seen as a means of controlling and regulating society, embedded within Cybernetics as a general approach to regulatory structures and processes, and with the then new computers as a means for the practical implementation of regulatory mechanisms (in Russian: 'pravo i kibernetika'; in German: 'Rechtskybernetik'; in Italian: 'giuscibernetica'; in Swedish: the field is known in the U.S. literature as 'AI and Law'). When the cybernetic movement lost steam in the 1970s, the field of Legal Cybernetics declined as well. Instead, it is replaced by a field with a more limited theoretical reach: Legal Informatics, focusing on the interrelationship between law and computers (or automated information processing). It is generally divided in three subfields: 1. Legal Information (or Documentation) Science, sometimes also Legal Information Retrieval, i.e. how to user computers to improve the accessibility of the vast amount of legal documents like laws, court decisions or legal commentaries; 2. Computational Law, i.e. the mechanization or automation of legal reasoning and decision-making; and 3. Administration & Management, i.e. the automation of juridical office work. A second organizing structure that has been proposed in the literature is the division in 1. the conditions, 2. the applications, and 3. the implications of the use of computers in law. The first subfield focuses on questions like Which part(s) of juridical work can be automated?, or How laws must be formulated in order to be automatable? The second subfield focuses on the development of practical applications and their use in juridical work, while the third subfield encompasses the use of computers in society on the legal systems, i.e. the development and enactment of laws governing computer use and mitigating the risks they pose for individuals, groups, organizations and society, e.g. coyright law, competition law, or data protection law. Since then, the field has considerably narrowed down, with basic research being especially rare. Analyzing the topics on the leading journals and conferences in this field, i.e. the journals 'MULL: Modern Uses of Logic in Law' (1959–1966), 'Jurimetrics Journal' (1966–1978), 'Jurimetrics' (1978–2015), and 'Artificial Intelligence and Law' (1992–2019) as well as the conferences 'ICAIL: International Conference on Artificial Intelligence and Law' (1987–2019), 'JURIX: International Conference on Legal Knowledge and Information Systems' (1988–2019), and 'IRIS: Internationales Rechtsinformatik Symposion' (1999–2019), the research is now confined to three main areas: automated reasoning, software systems for lawyers and legal scholars (now often called Legal Tech), and computer or information law. The lecture will shed light on the long history of research at the intersection of Law and Computer Science, and discuss what we can learn from these experiences for future cooperation between legal scholars and computer scientists.
