The dominant social scientific approach to studying judicial behavior treats judges as strategic actors pursuing their political preferences under institutional constraint. The intellectual roots of this rational choice approach are in American law’s long but sporadic engagement with pragmatist ideas. This article challenges that approach: a fully pragmatist account of judicial action provides a better description of the intellectual and social work of judging, and better explains how judges reach a decision in difficult cases that most affect the development of (...) law and its relationship to society. The article argues that the foundational intellectual problem for appellate judges is how to define the legal questions presented in a case. Definitions of legal questions arise from the interplay of habitual and creative action in the local social context of an appeals court. Professional and local interpretive habits and legal forms ordinarily do a great deal to define the key questions, which are not strictly determined when a case comes before a court. Unscripted small group interactions at oral arguments also figure in question definition; oral arguments are most important in the rare but legally important cases where habitual practices alone are insufficient to delimit the legal question judges must answer. Supported by extensive interviews with federal appeals judges and clerks, the article illustrates judges’ creative, interactional efforts to define an answerable question in a major asylum case decided in the Seventh Circuit Court of Appeals. Building from this case, the article describes the factors that shape judicial question definition, and describes the conditions when creative judicial action is likely to be most prominent. (shrink)
