61It should be recalled that, in proceedings under Article 267 TFEU, which is based on a clear separation of functions between the national courts and the Court of Justice, any assessment of the facts in the case is a matter for the national court. However, in order to give the national court a useful answer, the Court may, in a spirit of cooperation with national courts, provide it with all the guidance that it deems necessary (Case C-433/05 Sandström [2010] ECR I-2885, paragraph 35 and the case-law cited).
