61The second of those fundamental rights, which is affirmed in Article 47 of the Charter, requires that the person concerned must be able to ascertain the reasons upon which the decision taken in relation to him is based, either by reading the decision itself or by requesting and obtaining disclosure of those reasons, without prejudice to the power of the court having jurisdiction to require the authority concerned to disclose that information, so as to make it possible for him to defend his rights in the best possible conditions and to decide, with full knowledge of the relevant facts, whether there is any point in his applying to the court having jurisdiction, and in order to put the latter fully in a position to review the lawfulness of the decision in question (see Case C‑300/11 ZZ [2013] ECR, paragraph 53 and case-law cited, and also Kadi II, paragraph 100).
