66In the third place, as regards the Commission’s arguments set out in paragraphs 39 to 41 above, it should be borne in mind that, under Article 84(1) of the Rules of Procedure of the General Court, no new plea in law may be introduced in the course of proceedings unless it is based on matters of law or of fact which come to light in the course of the procedure. However, a plea or an argument which may be regarded as amplifying a plea put forward previously, whether directly or by implication, in the original application and which is closely connected therewith must be declared admissible (judgment of 11 July 2013, Ziegler v Commission, C‑439/11 P, EU:C:2013:513, paragraph 46 and the case-law cited).
