Reflecting on recent gender law reform within international law, this book examines the nature of feminist interventions to consider what the next phase of feminist approaches to international law might include. To undertake analysis of existing gender law reform and future gender law reform, the book engages critical legal inquiries on international law on the foundations of international law. At the same time, the text looks beyond mainstream feminist accounts to consider the contributions, and tensions, across a broader range of feminist methodologies than has been adapted and incorporated into gender law reform including transnational and postcolonial feminisms. The text therefore develops dialogues across feminist approaches, beyond dominant Western liberal, radical, and cultural feminisms, to analyse the rise of expertise and the impact of fragmentation on global governance, to study sovereignty and international institutions, and to reflect on the construction of authority within international law. The book concludes that through feminist dialogues that incorporate intersectionality, and thus feminist dialogues with queer, crip, and race theories, that reflect on the politics of listening and which are actively attentive to the conditions of privilege from which dominant feminist approaches are articulated, opportunity for feminist dialogues to shape feminist futures on international law emerge. The book begins this process through analysis of the conditions in which the author speaks and the role histories of colonialism play out to define her own privilege, thus requiring attention to indigenous feminisms and, in the UK, the important interventions of Black British feminisms.
