107Next, as regards the reliability of the information provided by the Council, the Court notes that, in accordance with settled case-law, the activity of the Court of Justice and of the General Court is governed by the principle of the unfettered assessment of the evidence, and it is only the reliability of the evidence before the Court which is decisive when it comes to the assessment of its value. In addition, in order to assess the probative value of a document, regard should be had to the credibility of the account it contains and, in particular, to the person from whom the document originates, the circumstances in which it came into being, the person to whom it was addressed and whether, on its face, the document appears to be sound and reliable (see, to that effect, judgment of 27 September 2012, Shell Petroleum and Others v Commission, T‑343/06, EU:T:2012:478, paragraph 161 and the case-law cited).
