113First, as regards, the alleged infringement by the Commission of Article 42 of the Charter of Fundamental Rights, relating to the right of access to documents, and Article 15(3) TFEU, it must be recalled that, according to the latter provision, the right of access to documents is subject to the principles and the conditions determined by the European Parliament and the Council by means of regulations, acting in accordance with the ordinary legislative procedure. Thus, Regulation No 1049/2001, adopted on the basis of Article 255 EC, the contents of which was enshrined in Article 15(3) TFEU, lays down the general principles and limits with regard to the right of access to documents held by the Commission. Furthermore, according to Article 52(2) of the Charter of Fundamental Rights, the rights recognised by the Charter which are based on the Treaties must be exercised under the conditions and within the limits defined by those treaties.
