38It is apparent from the case-law of the Court of Justice that any decision imposing or maintaining restrictive measures against a person must be taken on a sufficiently solid factual basis, and the EU Courts must then determine whether the facts alleged are made out in the light of the information or evidence provided and assess the probative value of that information or evidence in the circumstances of the particular case and in the light of any observations submitted in relation to them by, among others, the person concerned (see, to that effect, judgment of 18 July 2013, Commission and Others v Kadi, C‑584/10 P, C‑593/10 P and C‑595/10 P, EU:C:2013:518, paragraphs 119 and 124).
