226That said, it is apparent from the Court’s case-law that in deciding whether to exclude information and evidence obtained in contravention of the requirements of EU law, regard must be had, in particular, to the risk of breach of the adversarial principle and, therefore, the right to a fair trial entailed by the admissibility of such information and evidence (see, to that effect, judgment of 10 April 2003, Steffensen, C‑276/01, EU:C:2003:228, paragraphs 76 and 77). If a court takes the view that a party is not in a position to comment effectively on evidence pertaining to a field of which the judges have no knowledge and is likely to have a preponderant influence on the findings of fact, it must find an infringement of the right to a fair trial and exclude that evidence to avoid such an infringement (see, to that effect, judgment of 10 April 2003, Steffensen, C‑276/01, EU:C:2003:228, paragraphs 78 and 79).
