24As a preliminary point, it should be noted that the Court has previously had occasion, in its judgment of 20 April 2010 in Federutility and Others (C‑265/08, EU:C:2010:205), to outline a framework for analysis enabling the relevant national court to assess the compatibility with EU law of State intervention in prices, specifically in the natural gas sector. In that judgment and the subsequent case-law the Court gave some guidance as to the criteria on which such an assessment must be based, and it is in line with that case-law that the questions raised by the referring court should be examined (see judgments of 21 December 2011, Enel Produzione, C‑242/10, EU:C:2011:861, and 10 September 2015, Commission v Poland, C‑36/14, not published, EU:C:2015:570).
