What makes an international institution work for labor activists? Shaping international law through strategic litigation

Studies on international legal mobilization often analyze the mobilization efforts of activists at a single international court. Yet we know little about how activists choose among multiple international institutions to advance social justice claims. Drawing on comparative case studies of Turkish and British trade union activists' legal mobilization efforts and case law analysis, I show that activists, guided by their lawyers, probe multiple avenues to identify the legal institution with the highest judicial authority and is most responsive to activists' claims. Once they identify their target institution, the iterative process between a responsive court and activists' strategic litigation can build a court's jurisprudence in a new issue area, even if the court provides limited de jure rights protections. Activists primarily use international litigation strategy to leverage structural reforms at the domestic level and to set new international norms through precedents.
