2. NATIONAL ENERGY-SECURITY STRATEGIES AND JUDICIAL REVIEW

1. Introduction

National energy security concerns a state's capacity to maintain a reliable, affordable and sustainable supply of energy for households, businesses, public institutions and critical infrastructure. In South Africa, energy-security strategies may involve expanding electricity-generation capacity, diversifying the energy mix, strengthening transmission networks, procuring renewable energy, maintaining dispatchable generation and developing nuclear or other technologies.

Although energy strategy primarily falls within the responsibility of the executive and specialist regulators, energy-security decisions remain subject to constitutional and administrative-law requirements. Judicial review enables courts to determine whether governmental energy decisions were made lawfully, rationally, procedurally fairly and within the powers granted by legislation.

2. Constitutional and Legislative Framework

South African energy-security decisions operate within the Constitution of the Republic of South Africa, 1996, particularly the principles of legality, accountable government and administrative justice. Section 33 protects the right to administrative action that is lawful, reasonable and procedurally fair.

The Promotion of Administrative Justice Act 3 of 2000 (PAJA) provides grounds for reviewing administrative decisions. Courts may intervene where an administrator exceeds statutory authority, ignores relevant considerations, follows an unfair procedure, acts irrationally or commits a material error of law.

The Electricity Regulation Act 4 of 2006 (ERA) is also central. Section 34 has historically empowered the responsible Minister, acting with the energy regulator where required, to make determinations concerning new generation capacity and procurement. Energy security therefore operates through statutory powers rather than unlimited executive discretion.

3. Energy Security and Judicial Review

Courts generally recognise that determining the appropriate energy mix involves technical, economic and policy considerations. Judicial review does not ordinarily allow judges to substitute their preferred electricity policy for that chosen by government.

However, energy security cannot operate as a justification for disregarding legal requirements. Courts may examine whether authorities followed mandatory procedures, properly exercised statutory powers, considered legally relevant factors and provided required opportunities for public participation.

Thus, judicial review creates a balance between executive energy-policy discretion and constitutional accountability.

4. Case Law: Earthlife Africa Johannesburg v Minister of Energy

Case Name/Citation: Earthlife Africa Johannesburg and Another v Minister of Energy and Others (19529/2015) [2017] ZAWCHC 50; 2017 (5) SA 227 (WCC).

Facts: The dispute concerned governmental steps toward procuring approximately 9.6 GW of nuclear generation capacity, including ministerial determinations under section 34 of the Electricity Regulation Act and international nuclear-cooperation agreements. The applicants challenged several governmental decisions connected with the proposed nuclear programme.

Legal Issue: Whether the nuclear-procurement-related determinations and associated governmental actions complied with constitutional, statutory and procedural requirements.

Judgment: The Western Cape High Court held, among other things, that the relevant 2013 and 2016 section 34 determinations were unlawful and unconstitutional and should be reviewed and set aside. The court identified procedural defects, including inadequate public participation in relation to the determinations.

Legal Principle/Ratio Decidendi: Major energy-security programmes remain subject to the principle of legality, statutory requirements and procedurally fair decision-making. Strategic importance does not exempt energy decisions from judicial scrutiny.

Significance: The judgment demonstrates that courts need not determine whether nuclear power itself is desirable. Their constitutional role is instead to ensure that the government follows lawful procedures when implementing major energy strategies.

5. Case Law: Earthlife Africa Johannesburg v Minister of Environmental Affairs

Case Name/Citation: Earthlife Africa Johannesburg v Minister of Environmental Affairs and Others (65662/16) [2017] ZAGPPHC 58; [2017] 2 All SA 519 (GP).

Facts: The case concerned environmental authorisation for the proposed 1,200 MW Thabametsi coal-fired power station. Government argued that coal generation formed part of measures intended to maintain security of electricity supply, while Earthlife challenged the adequacy of consideration given to climate impacts.

Legal Issue: Whether environmental authorities could lawfully authorise the project without adequately considering its climate-change implications.

Judgment: The High Court found the Minister's decision reviewable and remitted the climate-change issue for reconsideration. It recognised climate impacts as legally relevant considerations within environmental decision-making.

Legal Principle/Ratio Decidendi: Energy security and environmental sustainability must be considered within the governing statutory framework. Security-of-supply objectives do not eliminate obligations to consider legally relevant environmental consequences.

Significance: The case demonstrates that national energy-security planning must integrate environmental protection, climate considerations and lawful administrative decision-making.

6. Conclusion

National energy-security strategies require substantial governmental flexibility because electricity systems involve complex questions of reliability, investment, affordability and technology. Nevertheless, constitutional government requires energy-security decisions to remain lawful, rational, transparent and procedurally proper. Judicial review therefore provides an accountability mechanism rather than a judicial replacement for energy policy. The Earthlife cases demonstrate that even strategically important nuclear and coal-generation decisions must comply with statutory procedures, environmental obligations and constitutional principles.
