The Supreme Court's Certiorari Decisions: Conflict as a Predictive Variable

In the period from 1947 to 1976, the United States Supreme Court has denied certiorari in more than half the cases involving conflict with Supreme Court precedent or intercircuit conflict. In both instances, the denial rate has been higher in the Burger Court than in the Vinson and Warren Courts and denial has been greater for intercircuit conflict cases than for cases in which the ruling in the lower court was in conflict with one or more Supreme Court precedents. When conflict was conceptualized as a predictor of decision and examined along with federal government as petitioning party, economic issues, and civil liberty issues, it was found to have 4 to 7 times the predictive power of the other variables combined for the Vinson and Warren Courts. For the Burger Court, the petitioning party variable was found to be a better predictor than conflict, but conflict was a much better predictor than the subject variables. Discriminant function models using the four predictor variables were able to account for up to 36.9% of the variance in the Supreme Court's certiorari decisions, almost all of which was the result of the contributions made by the conflict and party factors.
