Great Expectations: AI and Law as an Issue for Legal Semiotics

Abstract

Trying to build computerprograms that can assist the practicing lawyerin solving concrete cases is scientificallychallenging and financially attractive. So far,the practical results of such endeavors arerather modest, but that may change. This paperexamines the possible impact in the future ofadvanced advisory software on the semantics andpragmatics of law. Two kinds of computerprograms are discussed, viz., expertsystems and dialogue models. It is argued thatsuch systems may affect adjudication in someimportant ways, and that jurists shouldtherefore develop a more critical attitudetoward the use of such systems. Furthermore, itis argued that the widespread idea that the useof computers leads to more objectivity is onthe whole mistaken. As to the role of computersin legal decision making, the final question isnot: can they do it? But: do we want to let them doit? All this does not mean, however, thatjurists should turn away from ArtificialIntelligence and Law. On the contrary,developments in that field can be highlystimulating for legal theory and legal semiotics.
