63Moreover, as part of the review of the lawfulness of the reasons which are the basis of the decision to include or to maintain a person’s name on the list of persons subject to restrictive measures, the effectiveness of the judicial review guaranteed by Article 47 of the Charter of Fundamental Rights of the European Union requires that the Courts of the European Union determine, in addition to whether the reasons relied on are sufficiently detailed and specific, whether those reasons – or at the very least one of them – constitute in themselves a sufficient basis to support that decision. The Courts of the European Union must also ensure that that decision, which affects the person concerned individually, is taken on a sufficiently solid factual basis. That entails a verification of the factual allegations in the statement of reasons underpinning that decision, with the consequence that judicial review cannot be restricted to an assessment of the cogency in the abstract of the reasons relied on, but must concern whether those reasons, or, at the very least, one of those reasons, deemed sufficient in itself to support that decision, are substantiated (judgment of 1 August 2025, Timchenko v Council, C‑703/23 P, EU:C:2025:608, paragraph 36 and the case-law cited).
