19 May 1952
The then Minister of Justice, C.R. Swart, served two notices on Solly Sachs, an official of the Garment Workers' Union of South Africa (GWU). The first notice ordered Sachs to relinquish his position in the Union within thirty days and not to participate in any way in the activities of the union. The second order restricted his movements to the Transvaal and prohibited him from attending any meetings other than religious, social or recreational gatherings.
