Section 24(2)(b) of the Legal Practice Act 28 of 2014, which restricts admission as a legal practitioner to South African citizens and permanent residents, is constitutional. The differentiation on the basis of citizenship bears a rational connection to the legitimate government purpose of protecting employment opportunities for citizens and permanent residents. Section 22 of the Constitution expressly limits the right to choose one's trade, occupation or profession to citizens, and the State has no constitutional obligation to extend this right to foreign nationals. The distinction between permanent residents (who have a permanent right to live and work in South Africa) and other foreign nationals (who have temporary or conditional status) is rational. Where differentiation on the basis of citizenship does not result in destitution, does not constitute a blanket employment ban, and where affected persons remain able to work in related capacities, such differentiation does not amount to unfair discrimination. The State's sovereign power to regulate entry into professions and to adopt protectionist policies for citizens is a legitimate exercise of legislative authority that courts should not interfere with absent arbitrariness or irrationality.
