Sections 10(1) and 10(3) of the Gauteng Transport Infrastructure Act 8 of 2001 deprive landowners of certain property rights by restricting use and development of land within proposed road reserves, but this deprivation is not arbitrary under section 25(1) of the Constitution. A deprivation is arbitrary if the law does not provide sufficient reason for the deprivation or is procedurally unfair. Whether sufficient reason exists requires evaluation of the relationship between the means (the deprivation) and the ends (the purpose), considering the nature of the property, extent of deprivation, and whether less restrictive means are available. The deprivations here are not procedurally arbitrary because: (a) historical consultation processes were adequate given the circumstances; (b) it would be impractical to consult all affected owners retrospectively; and (c) mechanisms exist (sections 7, 8(9), 9(1)(c)) for individual concerns to be addressed. The deprivations are not substantively arbitrary because: (a) the purpose of protecting infrastructure planning involving substantial public expense is legitimate and compelling; (b) the restrictions are proportionate to this purpose; (c) landowners can apply for amendments to preliminary designs under section 8(9); (d) the restrictions do not prevent all use or alienation, only certain development changes; and (e) less restrictive means would not adequately protect the planning investment. The restrictions do not constitute expropriation under sections 25(2) and 25(3) because the state does not acquire rights in the property; it merely regulates use for public purposes. Expropriation requires acquisition by the state for public purposes, not mere regulatory restriction. The publication of notices under sections 10(1) and 10(3) is not administrative action because it merely brings transitional provisions into force without involving any administration of those provisions, similar to proclamation of commencement dates.
