The Form and Function of Oral Arguments in High Courts

Oral arguments provide one of the most significant—and visible—aspects of the judicial process. This chapter examines the comparative literature on this critical procedure, particularly at apex courts. It focuses on three central questions. Recognizing that at many high courts, hearings are the exception rather than the rule, the chapter first considers explanations for why courts hold hearings when they do. It emphasizes three prominent explanations: the need for information, the need for legitimacy, and the need for public awareness. The second section then engages with research on the conduct of hearings, including the length of proceedings, the extent to which judges speak, and how characteristics like gender affect proceedings. The third and final section of the chapter discusses the legal and political impact, if any, of hearings. In particular, the chapter examines the factors that allow or inhibit attorneys from persuading judges, as well as the effect of hearings on the political environment in which a court operates. Each section highlights work both from the US and comparative contexts to reveal the trends in studies of oral arguments as well as the opportunities created by expanding the scope of research beyond the US Supreme Court. Each section concludes with a discussion of potential avenues for future work, such as the systematic study of case complexity on the use of hearings and the impact of institutions like ombudsmen on the conduct and impact of the procedure. The chapter then ends with additional concluding thoughts and suggestions for further research.
