Judgment_paragraph 33 · Cementos Portland Valderrivas, SA v European Commission (T-296/11)

33For the purpose of addressing this limb of the plea in law, it should be borne in mind that the administrative procedure under Regulation No 1/2003, which takes place before the Commission, is divided into two distinct and successive stages, each having its own internal logic, namely a preliminary investigation stage and an inter partes stage. The preliminary investigation stage, during which the Commission uses the powers of investigation provided for in Regulation No 1/2003 and which covers the period up until the notification of the statement of objections, is intended to enable the Commission to gather all the relevant information tending to prove or disprove the existence of an infringement of the competition rules and to adopt an initial position on the course of the procedure and how it is to proceed. By contrast, the inter partes stage, which covers the period from the notification of the statement of objections to the adoption of the final decision, must enable the Commission to reach a final decision on the alleged infringement (see, to that effect, Case T-99/04 AC-Treuhand v Commission [2008] ECR II-1501, paragraph 47).
