The High Court in Pretoria on FRIDAY  found that the National Energy Regulator of South Africa's (NERSA) decision to consider municipalities' applications for electricity tariff increases without the required cost studies is unlawful and invalid. According to Afriforum this means that the regulator may not consider any applications for electricity tariff increases from municipalities unless the required cost studies are also submitted. AfriForum submitted an urgent application to the court earlier this month to prevent NERSA from proceeding with these considerations.
