36As regards the information that any request for a preliminary ruling must contain, it should be borne in mind that, according to settled case-law, in the context of the cooperation between the Court of Justice and the national courts established by Article 267 TFEU, the need to provide an interpretation of EU law which will be of use to the national court makes it necessary for that court to set out the factual and legislative context of the questions referred or, at the very least, to explain the factual circumstances on which those questions are based. The Court is empowered to rule on the interpretation or validity of EU provisions only on the basis of the facts which the national court puts before it (orders of 5 October 2017, OJ, C‑321/17, not published, EU:C:2017:741, paragraph 12, and of 5 June 2019, Wilo Salmson France, C‑10/19, not published, EU:C:2019:464, paragraph 12).
