1. Section 7(2) of the Constitution imposes a duty on the State and organs of state to respect, protect, promote and fulfil the rights in the Bill of Rights. 2. Systemic failures by organs of state that result in loadshedding and inability to provide consistent electricity supply can constitute breaches of constitutional obligations where they unjustifiably infringe Bill of Rights guarantees. 3. While the Constitution does not expressly provide for a right to electricity, loadshedding can infringe other guaranteed rights including dignity, life, security, environment, healthcare, water, food and education. 4. Once unconstitutional conduct is found, a court must make a declaration of invalidity pursuant to Section 172(1)(a), though the granting of further remedial relief involves discretion guided by what is just and equitable. 5. Courts must balance the need for effective constitutional remedies against separation of powers and should not unduly intrude into the executive sphere, particularly on matters implicating national budgets and economic policy. 6. Just and equitable relief may include supervisory orders directed at specific organs of state to ensure constitutional compliance, particularly regarding vulnerable institutions. 7. NERSA's two-stage tariff determination methodology is lawful and rational: allowable revenue is determined at the MYPD stage based on efficient forward-looking costs; actual tariffs per customer category including cross-subsidisation are determined at the ERTSA stage. 8. Section 15(1)(e) of the Electricity Regulation Act permits but does not mandate consideration of cross-subsidisation at any particular stage; NERSA may rationally determine cross-subsidies at the ERTSA stage after determining allowable revenue. 9. NERSA need not budget prospectively for corruption, fraud and wasteful expenditure at the revenue determination stage; such matters can be addressed retrospectively through the Regulatory Clearing Account mechanism.
