33It is also important to note that the application of the European Union rules on State aid is based on an obligation of sincere cooperation between, on the one hand, the national courts and, on the other, the Commission and the Courts of the European Union, in the context of which each acts on the basis of the role assigned to it by the Treaty. In the context of that cooperation, national courts must take all the necessary measures, whether general or specific, to ensure the fulfilment of the obligations under European Union law and refrain from taking those which may jeopardise the attainment of the objectives of the Treaty, as follows from Article 4(3) TEU. Therefore, national courts must, in particular, refrain from taking decisions which conflict with a decision of the Commission, even if it is provisional (see judgment of 21 November 2013, Deutsche Lufthansa, C‑284/12, EU:C:2013:755, paragraph 41).
