The South African Law Reform Commission received a submission from the Traditional Healers Organisation requesting the investigation of the constitutionality of the Witchcraft Suppression Act of 1957 and the Mpumalanga Witchcraft Suppression Bill of 2007, the drafting of which was suspended in 2008. On 23 March 2010 the Minister of Justice and Constitutional Development approved a South African Law Reform Commission project to review witchcraft legislation. In March 2012 the South African Law Reform Commission advised that Ms Jennifer Joni has been designated as researcher and Judge Dennis Davis has been designated as project leader for Project 135: Review of witchcraft legislation. Dr Theodore Petrus, who completed a doctoral thesis on witchcraft-related crime in 2009, was invited to become part of an advisory committee to assist in the review.
