On any given day, almost 11 million people globally are deprived of their liberty. In 2020, the global female population was estimated to be 741,000, an increase of 105,000 since 2010. In order to investigate progress in the adoption of the Bangkok Rules since 2010, we conducted a legal realist assessment based on a global scoping exercise of empirical research and United Nations (UN) reporting, using detailed MESH terms across university and UN databases. We found evidences in 91 documents which directly relate to violations of the Bangkok Rules in 55 countries. By developing a realist account, we document the precarious situation of incarcerated women and continued evidence of systemic failures to protect them from custodial violence and other gender-sensitive human rights breaches worldwide. Despite prison violence constituting a complex and multifaceted phenomenon, very little research (from the United States, Canada, Brazil, Mexico, and Australia) has been conducted on custodial violence against women since 2010. Although standards of detention itself is a focus of UN universal periodic review, special procedures (violence against women) and concluding observations by the UN committees, very few explicitly mentioned women, and the implications of violence against them while incarcerated. We highlight three central aspects that hinder the full implementation of the Bangkok Rules; the past decade of a continued invisible nature of women as prisoners in the system; the continued legitimization, normalization, and trivialization of violence under the pretext of security within their daily lives; and the unawareness and disregard of international (Bangkok and others) rules.
