57It follows from the case-law of the Court that the effectiveness of the judicial review guaranteed by the first paragraph of Article 47 of the Charter requires, inter alia, that the person concerned is able to defend his or her rights in the best possible conditions and to decide, in full knowledge of the facts, whether it would be useful to bring an action against a given entity before the competent court (see, to that effect, judgment of 8 May 2019, PI, C‑230/18, EU:C:2019:383, paragraph 78 and the case-law cited).
