44It must be observed that the fourth paragraph of Article 263 TFEU provides for two situations in which natural or legal persons are accorded standing to institute proceedings against an act not addressed to them. First, such proceedings may be instituted if the act is of direct and individual concern to them. Second, such persons may bring proceedings against a regulatory act not entailing implementing measures if that act is of direct concern to them (judgments of 19 December 2013, Telefónica v Commission, C‑274/12 P, EU:C:2013:852, paragraph 19, and of 18 October 2018, Internacional de Productos Metálicos v Commission, C‑145/17 P, EU:C:2018:839, paragraph 32).
