28In that regard, it is sufficient to state that, in accordance with the Court’s settled case-law, in the preliminary ruling procedure under Article 267 TFEU, based on a clear separation of functions between the national courts and the Court of Justice, the national court alone has jurisdiction to find and assess the facts in the dispute in the main proceedings. In that context, the Court is empowered to rule solely on the interpretation or validity of EU law in the light of the factual and legal situation as described by the referring court, in order to provide that court with such guidance as will assist it in resolving the dispute before it (judgment of 20 December 2017, Schweppes, C‑291/16, EU:C:2017:990, paragraph 21 and the case-law cited).
