This study broadens the base of judicial impact studies in education, extends a theoretical model appropriate for such studies, and suggests implications for policy and practice in the area of public sector labor relations, particularly with reference to the use of antistrike injunctions. Focal point for the study is an examination of the 1973 teacher strike in St. Louis, where teachers defied an antistrike injunction for four weeks. In his discussion, the author utilizes the French-Raven social power model to describe the Board of Education's efforts to mobilize judicial power against the teachers, the teacher organization's efforts to neutralize the board's strategy, and the outcomes of these efforts.
