This report is the third in a planned five-volume series looking at the impacts of stra tegic litigation. Strategic litigation is of keen interest to the Open Society Foundations (OSF), which both supports strategic litigation and engages in it directly—and thus has an interest in gaining an unbiased view of its promises and limitations. Strategic litiga tion can be a powerful engine of social change. Yet it can also be costly, time-consuming, and risky. Studying its strengths, weaknesses, unintended consequences, and the condi tions under which it flourishes or flounders may yield lessons that enhance its potential and improve future social change efforts.
