In Vergara v. California (2014), a trial-level court ruled that California laws governing teacher tenure and dismissal were unconstitutional. This study analyzes Vergara in light of the shifting use of the courts to promote equal educational opportunities and the changing power bases of educational interest groups, including educational advocacy groups and teacher unions. This study particularly uses policy regimes theory to analyze the relationship between political interests, ideas, and institutions and highlights how the case represents an inversion of how educational interest groups have traditionally used the courts as vehicles for effecting education reform. Grounded in this analysis, this study explores legal and policy implications for both courts and reformers acting in this new context.
