Research on movement outcomes primarily examines the conditions under which social movements influence the law. Less attention has been given to the influence that legal change might have on the movement's subsequent development. Does the achievement of legal goals help the movement mobilize or does the movement experience decline once change occurs? Using unique measures of gay and lesbian mobilization, I investigate the influence of legal change on the number of gay and lesbian movement organizations in each state from 1974 to 1999. Results demonstrate that the impact of legal change is contingent on the type of reform achieved and the cultural context surrounding the decision.
