15While certain pleas may, and indeed must, be raised by the courts of their own motion, such as the question whether a statement of reasons for the decision at issue is lacking or is inadequate, which falls within the scope of essential procedural requirements, a plea going to the substantive legality of that decision, which falls within the scope of infringement of the Treaties or of any rule of law relating to their application, within the meaning of Article 263 TFEU, can, by contrast, be examined by the Courts of the European Union only if it is raised by the applicant (judgment of 10 December 2013, Commission v Ireland and Others, C‑272/12 P, EU:C:2013:812, paragraph 28 and the case-law cited).
