Knowledge production through legal mobilization: Environmental activism against the U.S. military bases in East Asia

There is growing interest in social movement actors as knowledge producers, but many movements have limited ability to access or produce credible, authoritative information. Building on sociolegal scholarship and social movement studies, we show how movements can overcome knowledge gaps they have via-à-vis state authorities and contribute to public knowledge through institutional tactics. We argue that features of the process of legal mobilization activate mechanisms that bolster movements' credibility, reveal or generate information, and thereby facilitate social movement knowledge production. We theorize these dynamics by analyzing environmental activism against U.S. military bases in Japan and South Korea, which allows us to leverage most similar legal contexts and types of claims to identify and illustrate the mechanisms.
