On 27 February 2018, the Court of Justice of the European Union rendered its judgment in the Case C-266/16 The Queen, on the application of Western Sahara Campaign UK v Commissioners for Her Majesty’s Revenue and Customs and Secretary of State for Environment, Food and Rural Affairs.
The Court found that the Fisheries Agreement concluded between the EU and Morocco is valid in so far as it is not applicable to Western Sahara and to its adjacent waters. It should be recalled that according to the opinion rendered by the Advocate General Wathelet, the Fisheries Agreement concluded between the EU and Morocco would be invalid because it applies to the Western Sahara and its adjacent waters.
