Much needs to be pointed out though. While South Africa signed the WPPT on 12 December 1997, a copy of the presidential minute authorising such signature is not in the Department of Trade and Industry's, DTI's, possession and could not be obtained from the Presidency. The Department of International Relations and Co-operation, Dirco, has advised that we express our interest to be bound by way of an instrument of accession rather than an instrument of ratification. It is incumbent on us to ensure that the appropriate provisions exist in our international laws to ensure effective enforcement of the rights of the treaty.
