Purpose: The global spotlight is increasingly shone on the situation of women in the male-dominated prison environment. Africa has observed a 24% increase in its female prison population in the past decade. This year is the 10-year anniversary of the United Nations Rules for the Treatment of Women Prisoners and Non-custodial Measures for Women Offenders (the Bangkok Rules) adopted by the General Assembly on 21 December 2010. Design/methodology/approach: Using a legal realist approach, this paper examines South Africa's progress in adopting the Bangkok Rules. This paper documents the historical evolution of the penal system since colonial times, focused on the development of recognition, protection and promotion of human rights of prisoners and an assessment of incarcerated women's situation over time. Findings: The analysis of the human rights treaties, the non-binding international and regional human rights instruments, African court and domestic jurisprudence and extant academic and policy-based literature is cognizant of the evolutionary nature of racial socio-political dimensions in South Africa, and the indeterminate nature of application of historical/existing domestic laws, policies and standards of care when evaluated against the rule of law. Originality/value: To date, there has been no legal realist assessment of the situation of women in South Africa's prisons. This paper incorporates race and gendered intersectionality and move beyond hetero-normative ideologies of incarcerated women and the prohibition of discrimination in South African rights assurance. The authors acknowledge State policy-making processes, and they argue for substantive equality of all women deprived of their liberty in South Africa. [ABSTRACT FROM AUTHOR]
