Judgment_paragraph 35 · A-Rosa Flussschiff GmbH v Union de recouvrement des cotisations de sécurité sociale et d’allocations familiales d’Alsace (Urssaf), venant aux droits de l’Urssaf du Bas-Rhin and Sozialversicherungsanstalt des Kantons Graubünden (C-620/15)

35As a preliminary point, it should be borne in mind that, in accordance with the Court’s settled case-law, in a reference for a preliminary ruling under Article 267 TFEU, which is 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 case in the main proceedings. In that context, the Court is only empowered to rule 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 28 July 2016, Kratzer, C‑423/15, EU:C:2016:604, paragraph 27).
