An incisive look at the citrus trade dynamic between South African and the European Union. The author sets out to identify potential grounds of discrimination as a consequence of the European Commission's trade restrictions to counter the spread of the Citrus Black Spot Disease (CBS). Arbitrary discrimination is countered by the Sanitary and Phytosanitary Agreement (SPS Agreement), of which both South Africa and the European Unions are members. The provisions of the SPS Agreement are analysed with reference to the trade restriction and available scientific evidence conducted on the spread of CBS in different regions.
