1. Member States shall not apply any quantitative restrictions on exports to any other Member State, except where otherwise provided for in this Protocol. 2. Member States may take such measures as are necessary to prevent erosion of any prohibitions or restrictions which apply to exports outside the Community, provided that no less favourable treatment is granted to Member States than to third countries. Article 9 GENERAL EXCEPTIONS Subject to the requirement that such measures are not applied in a manner which would constitute a means of arbitrary or unjustifiable discrimination between Member States, or a disguised restriction on intra-SADC trade, nothing in Article 7 and 8 of this Protocol shall be construed as to prevent the adoption or enforcement of any measures by a Member State: a) necessary to protect public morals or to maintain public order; b) necessary to protect human, animal or plant life or health; c) necessary to secure compliance with laws and regulations which are consistent with the provisions of the WTO; d) necessary to protect intellectual property rights, or to prevent deceptive trade practices; e) relating to transfer of gold, silver, precious and semi-precious stones, including precious and strategic metals; f) imposed for the protection of national treasures of artistic, historic or archaeological value;
