82As the Court of Justice observed in Case 312/84Continentale Produkten Gesellschaft v Commission [1987] ECR 841, paragraph 11, the review procedure applies ‘if there is a change in the circumstances on the basis of which the values applied in the regulation imposing the antidumping duties were established’. The purpose of the review procedure is therefore to adapt the duties imposed to take account of an evolution in the factors which gave rise to them and the procedure therefore presupposes that those factors have altered.
