The binding legal principles established are: (1) The power to 'restrict' activities under section 9(1)(a)(ii) of NEMBA, when issuing norms and standards, is not limited to partial limitations but can include measures that severely curtail or effectively prohibit certain activities, particularly when interpreted contextually with sections 97 and 98 of NEMBA and the broader environmental legislative framework; (2) The distinction between 'restrict' and 'prohibit' in NEMBA is semantic rather than substantive, especially since section 98 permits conditional prohibitions which are effectively restrictions; (3) Environmental legislation must be interpreted synergistically and contextually, with NEMBA being read together with NEMA, CITES obligations, and implementing regulations to give effect to South Africa's constitutional environmental rights and international obligations; (4) Norms and standards issued under section 9 of NEMBA constitute subordinate legislation with legal force that must be obeyed unless set aside; (5) Clauses 12(4) and (5) of the Norms and Standards impose restrictions rather than absolute prohibitions, as they permit export/import of elephants in specific circumstances (not in controlled environments under 2000 ha, or temporarily for bona fide circus purposes).
