The appellants were business entities that manufacture, import, market and sell angling equipment, including bait-carrying drones and remote-controlled bait-carrying devices. On 24 February 2022, the Deputy Director-General for Fisheries Management (DDG) published a notice advising the public that the use of motorised devices such as bait-carrying drones, bait-carrying remote-controlled boats and other remotely operated vehicles, as well as motorised electric reels, are prohibited for angling. Following this notice, the appellants experienced a rapid decline in demand for their products, with order cancellations and demands for reimbursement from clients. The appellants brought an application in the Gauteng Division High Court seeking a declaratory order that the use of drones and remote-controlled devices is not prohibited under the Marine Living Resources Act 18 of 1998 and its regulations, and that the DDG should withdraw the public notice. The high court dismissed the application and the matter was appealed to the Supreme Court of Appeal with leave.
