In this Introduction to the book Frontiers of Gender Equality: Transnational Legal Perspectives (2023), editor Rebecca Cook shows how a chorus of voices introduces new and different discourses about the wrongs of gender discrimination and explains the multiple dimensions of gender equality. This volume demonstrates that the wrongs of discrimination can best be understood from the perspective of the discriminated, and that gender discrimination persists and grows in new and different contexts, widening the gap between the principle of gender equality and its realization, particularly for subgroups of women and LGBTQ+ peoples.Frontiers of Gender Equality provides retrospective views of the struggles to eliminate gender discrimination in national courts and international human rights treaties. Focusing on gender equality enables comparisons and contrasts among these regimes to better understand how they reinforce gender equality norms. Different regional and international treaties are examined, those in the forefront of advancing gender equality, those that are promising but little known, and those whose focus includes economic, social, and cultural rights, to explore why some struggles were successful and others less so. The book illustrates how gender discrimination continues to be normalized and camouflaged, and how it intersects with other axes of subordination, such as indigeneity, religion, and poverty, to create new forms of intersectional discrimination.With the benefit of hindsight, the book’s contributors reconstruct gender equalities in concrete situations. Given the increasingly porous exchanges between domestic and international law, various national, regional, and international decisions and texts are examined to determine how better to breathe life into equality from the perspectives, for instance, of Indigenous and Muslim women, those who were violated sexually and physically, and those needing access to necessary health care, including abortion. The conclusion suggests areas of future research, including how to translate the concept of intersectionality into normative and institutional settings, which will assist in promoting the goals of gender equality
