This study tested theoretical propositions concerning agenda-setting by minority political groups in the United States to see if they had the scope to be applicable to American Indian tribes or if there were alternative explanations for how this group places its agenda items on the formal agenda and resolves them. Indian tribes were chosen as the case study because they are of significantly different legal and political status than other minority groups upon which much of the previous research has been done. The study showed that many of the theoretical propositions regarding agenda-setting by minority groups were explanatory for agenda-setting by Indian tribes. The analyses seemed to demonstrate that Indian tribes use a closed policy subsystem to place tribal agenda items on the formal agenda. The analyses demonstrated that most tribal agenda items resolved by Congress involve no major policy changes but rather incremental changes in existing policies. The analyses also demonstrated that most federal court decisions involving Indian tribes have no broad impact or significance to all Indian tribes. The analyses showed that both Congress and the federal courts significantly influence the tribal agenda but the relationship between the courts and Congress in agenda-setting in this area of policy …

The focus of this investigation is the relationship of the United States Supreme Court's functional performance to its environment. Three functions of courts are noted in the literature: conflict resolution, social control and administration. These functions are operationalized for the United States Supreme Court. Hypotheses are developed relative to the general performance of these three functions by all courts. Box-Jenkins time series analysis is then used to test these hypotheses in relation to the performance of the United States Supreme Court. The primary analysis rests upon a data set that includes all non-unanimous decisions of the Supreme Court from 1916 to 1986. A supplemental analysis is conducted using all formal decisions for the 1953 to 1986 period. The results suggest that intellectual resources, legal resources, modernization, and court discretion are significant influences on the functional performance of the United States Supreme Court. Future research must consider these influences in the development of a general theory of courts.
