If the judicial construction of Europe was not catalyzed by innately activist judges, who were the pioneers of change? Focusing on the 1960s-early 1980s, Chapter 5 introduces the first Euro-lawyers: A vanguard of independent-minded WWII survivors who sought to unite Europe via bottom-up lawyering. Less institutionally constrained than judges, they nonetheless had to erode ubiquitous knowledge deficits and habits embodied by courts and clients. To this end, they cultivated local litigants and disputes exposing national barriers to European integration; constructed test cases to introduce local judges to European rules they hardly knew; cajoled their interlocutors to solicit the ECJ by ghostwriting their referrals; and thus generated opportunities for the ECJ to render pathbreaking judgments. The chapter combines oral history interviews, materials from the ECJ and lawyers’ personal archives, secondary historiographies and newspaper records, and geocoded data of the first referrals to the ECJ. The chapter speaks to readers seeking a new perspective on the origins of European integration, the creativity and mischievousness of strategic litigation, how lawyers cultivate the rights-consciousness of litigants and the activism of judges, and how individuals promote novel practices that cut against imagined possibilities.
