29As Advocate General Jacobs made clear in point 30 of his Opinion in Case C-36/92 PSEP v Commission [1994] ECR I-1911, I-1914, the obligation to state the purpose of the request means ‘of course that [the Commission] must identify the suspected infringement of the competition rules’, ‘[t]he necessity of the information must be judged in relation to the purpose stated in the request for information’ and ‘[t]he purpose must be indicated with reasonable precision, otherwise it will be impossible to determine whether the information is necessary and the Court will be prevented from exercising judicial review’.
