This chapter studies some of the most important ethical topics involving the use of artificial intelligence (AI) within the legal system itself and examines how central legal values might unintentionally or intentionally change with increased use of AI in law. Ethical issues surrounding AI use in law often share a common theme. As AI becomes increasingly integrated within the legal system, how can society ensure that core legal values are preserved? Among the most important of these legal values are: equal treatment under the law; legal results arising from law, principle, and facts rather than social status or power; procedural fairness and due process; fairness in design and application of the law; transparency in legal substance and process; adequate access to justice for all; integrity and honesty in creation and application of law; and judicial, legislative, and administrative efficiency. The central ethical challenge is to identify the ways in which the use of AI may be shifting core legal values and to ensure that these crucial values are preserved in the technological transition. A more positive view also identifies the ways in which AI technology can not only preserve central values, but rather, can foster and enhance these values to the betterment of the legal system and society overall.
