This chapter advances a human-centered artificial intelligence approach (HCAI) to applications of artificial intelligence (AI) in the judiciary. It argues that while AI offers much potential for augmenting a growing range of functions traditionally performed by human actors in courts, preserving HCAI principles of fairness, accountability, transparency, proportionality, and user-centeredness is paramount. It assesses the importance of explainable AI and contestable AI, surveys examples from several jurisdictions, and proposes a principled framework for permissible AI use in courts, with a spectrum of five zones reflecting a continuum from low-risk administrative functions to high-risk adjudicative determinations. In the final analysis, the chapter suggests that HCAI is central to safeguarding human agency in judicial processes increasingly influenced by AI.
