1. Section 23(1)(a) of the Private Security Industry Regulation Act is not unconstitutional when read together with section 23(6), which provides for exemptions on good cause shown. 2. Discrimination between citizens/permanent residents and refugees in the security industry does not constitute unfair discrimination when the exemption provision (section 23(6)) is properly interpreted and applied. 3. In determining 'good cause' under section 23(6), decision-makers must consider: (a) the special legal status of recognised refugees under international and domestic law; (b) personal circumstances of the applicant; (c) length of stay in South Africa; (d) the character and sensitivity of the security work involved; (e) previous employment history; (f) ability to produce required documentation. 4. Being a recognised refugee in itself goes a long way to establishing 'good cause' for exemption under section 23(6). 5. The Authority's decisions refusing registration solely on the basis of non-citizenship/non-permanent residence, without proper consideration of section 23(6) exemption, were flawed and subject to administrative review. 6. South Africa's international law obligations under the 1951 UN Convention Relating to the Status of Refugees must inform the interpretation of domestic legislation affecting refugees, particularly the right to seek employment under section 27(f) of the Refugees Act.
