This study analyzes the nexus between the executive and judicial branches in understanding presidential success in domestic policy making from a system of separated powers perspective. The author investigates the nature of the interaction between the solicitor general and the Supreme Court's rulings in cases in which the federal government participated in the subissue area of civil rights during the Kennedy administration. The author found that the administration's civil rights litigation stralegy was highly succesful before the Warren Court. However, a content analysis of the solicitor general‘s briefs revealed a more complex and cautious approach to the civil rights cases. I conclude by suggesting that an insightful line of inquiry into understanding presidential influence in domestic policy making should include, not exclude, the Supreme Court.
