The South African Department of Correctional Services has a legislative mandate of detaining offenders in safe custody whilst ensuring their human dignity amongst others. This stems from section 2 of the Correctional Services Act 111 of 1998 as amended. In addition to that, chapter 3 of this Act makes provision for conditions under which offenders should be treated, conditions of human dignity. This piece of legislation is effectively giving effect to the Bill of Rights as articulated in chapter two of the Constitution of the Republic of South Africa of 1996. It is expected of the department to treat offenders according to the provisions of not only this Constitution and Correctional Services Act 111 of 1998 as amended but also to comply with the international conventions and treaties. Extensive empirical and non-empirical studies on the treatment of offenders have been conducted by various scholars in the field of penology but not much has been done to bring to the fore knowledge with regard to the developmental trend of the treatment of offenders. It is against this backdrop that a qualitative study through systematic review of literature was conducted to bring together and examine available literature. In other words, a systematic literature review was conducted to determine if there is a developmental trend towards the treatment of offenders in South Africa as required by the prescripts of the law. Furthermore, this study was conducted to also demonstrate the researcher’s knowledge in the field of penology. The focus was on the central theories identified as offenders’ rights. The Department of Correctional Services identified eight offenders’ rights and sees them as its Constitutional mandate (Department of Correctional Services, 2013:8). This study has found a violation of the offenders’ right to equality to be diminishing over time. Apart from that, this study reveals a substantial violation of offenders’ rights because out of seven offenders’ rights, only one [freedom of religion] appears be successfully protected and promoted by the department. This study further present the recommendations and suggested areas of further research. / Penology / D. Litt. et Phil. (Penology)
