Using Cambodia as a case study, this article examines cause lawyering in a repressive political environment. It focuses on “closeted” cause lawyering, a practice that we define as the intentional pursuit of change through the legal process that is concealed for strategic purposes. Situated within the wider scholarship on (cause) lawyering in general and authoritarian Southeast Asia and China in particular, the article draws upon interviews conducted over seven years in Cambodia with 37 lawyers and human rights defenders working in practice areas considered politically controversial by the authoritarian state. We identify how closeted cause lawyers operate in such a way as to ensure professional and personal survival while quietly advancing their goals across three settings, including dignity restoration work with clients, legal professionalism in court and sustaining a moral community of like-minded lawyers. The article underscores the ongoing relevance of cause lawyering even where intentionality must be hidden, as well as the enduring importance of cause lawyers’ efforts to preserve an ideal of the rule of law. We conclude by suggesting that the authoritarian turn in a range of democracies, including the Unites States, suggests that closeted cause lawyering may be required to defend democracy even among conventional lawyers.
