The binding legal principles are: (1) Rationality requires an objective inquiry into whether legislative means are rationally connected to a legitimate governmental purpose; it does not test fairness, reasonableness or whether better alternatives exist - those are matters for proportionality analysis under section 36. (2) Section 12(1)(c) of the Constitution protects the security of person of road accident victims from violence, imposing duties on the state to protect physical integrity, but this constitutional duty need not always include a civil claim for damages in delict; statutory compensation schemes can constitute adequate protection if reasonable and justifiable. (3) Where a statutory scheme abolishes a common law remedy but provides an alternative statutory remedy, the limitation of constitutional rights (such as security of person) may be justified where the scheme pursues legitimate purposes (financial viability, equity, sustainability) and the limitation is reasonable and justifiable. (4) Regulations made under empowering legislation must be rationally connected to the objectives of the empowering provision and must comply with constitutional rights, including socio-economic rights. (5) A regulation prescribing tariffs for healthcare services that: (a) cannot procure services in the private sector, (b) excludes essential services needed by vulnerable groups, (c) forces reliance on public facilities that cannot adequately provide for those needs, and (d) produces minimal cost savings, is not rationally related to providing reasonable healthcare and violates section 27(1)(a) of the Constitution. (6) Where government undertakes complex policy reform through incremental measures, courts should permit reasonable leeway to deal with problems one step at a time, provided each step is rational and constitutionally compliant.
