The appellants are companies involved in the manufacture, importation and sale of angling equipment, including bait-carrying drones and remote-controlled boats. On 24 February 2022, the first respondent, the Deputy Director-General for Fisheries Management, issued a public notice stating that the use of motorised devices such as bait-carrying drones, remote-controlled boats and motorised electric reels is prohibited for recreational angling. The appellants alleged that this notice caused significant financial harm to their businesses and contended that neither the Marine Living Resources Act 18 of 1998 nor its regulations prohibit such devices. They sought declaratory relief that the use of these devices is lawful and that the notice was unlawful and of no legal effect. The High Court dismissed the application, leading to an appeal to the Supreme Court of Appeal.
