“Pursuant to the principle of sincere cooperation, the Union and the Member States shall, in full mutual respect, assist each other in carrying out tasks which flow from the Treaties. The Member States shall take any appropriate measure, general or particular, to ensure fulfilment of the obligations arising out of the Treaties or resulting from the acts of the institutions of the Union. The Member States shall facilitate the achievement of the Union's tasks and refrain from any measure which could jeopardise the attainment of the Union's objectives.”
“It must be borne in mind that the application of the EU State aid rules is based on a duty of sincere cooperation between the national courts, on the one hand, and the Commission and the European Union courts, on the other, in the context of which each acts on the basis of the role assigned to it by the FEU Treaty. In the context of that cooperation, national courts must take all the measures, whether general or specific, necessary to ensure fulfilment of the obligations under EU law and must refrain from those that may jeopardise the attainment of the objectives of the Treaty, as follows from Article 4(3) TEU. Accordingly, national courts must, in particular, refrain from taking decisions that conflict with a decision of the Commission (judgment of21 November 2013 , Deutsche Lufthansa, C-284/12, EU:C:2013:755, paragraph 41).”
“The duty under Article 4(3) TEU is binding on all authorities of the Member States, including the courts: seeCase C-344/98 Masterfoods Ltd v HB Ice Cream Ltd[2000] ECR I-11369 ("Masterfoods") at [49]. The general principle of legal certainty, which underpins the duty of sincere cooperation, requires Member States to avoid making decisions that could conflict with a decision contemplated by the Commission: seeCase C-234/89 Delimitis v Henniger Brau[1991] ECR I-935 at [47] ("Delimitis"); Masterfoods at [51] and National Grid Electricity Transmission v ABB Ltd[2009] EWHC 1326 at [24.] It is only where, in the words of the Commission in Delimitis at [50], there is "scarcely any risk" of a conflict between decisions of domestic and EU institutions, that the national authorities should proceed. Where the EU and domestic authorities have overlapping jurisdictions i.e. considering the same or similar matters, the risk of conflicting decisions will be high.”
“In my view these cases reinforce and support the following propositions. (1) The courts here should take all reasonable steps to avoid or reduce the risk of arriving at a conclusion which is at variance with a decision of, or on appeal from, the Commission in relation to competition law. (2) Except in the clearest cases of breach or non-breach, it will be a proper exercise of discretion to stay proceedings here to await the outcome of the Community proceedings.”
“Article 4 (3) does not have direct effect in itself, but it can be used as an additional argument where the Member State in question is alleged to have breached an unconditional and sufficiently precise obligation. In such a case, the national court, as an institution of the Member State, has to refrain from applying the provisions of domestic law which prevent EU law from having its full effect.”
“… an award registered under section 1 above shall, as respects the pecuniary obligations which it imposes, be of the same force and effect for the purposes of execution as if it had been a judgment of the High Court given when the award was rendered pursuant to the Convention and entered on the date of registration under this Act, …”
“The exclusion of another remedy [that is, other than under the ICSID Convention review procedures] means that a party to ICSID proceedings that is dissatisfied with the Award may not turn to another forum to seek relief for the same claim. Once the ICSID tribunal has rendered its award and the review procedures under the Convention have been exhausted, the case is res judicata. The principle ne bis in idem precludes resort to any national or international remedy.”
“56 In that regard, it must, first, be stated that the situation at issue here is distinguishable from that in Lucchini, relied on by the Commission, where the Court held that European Union law precludes the application of a provision of national law which seeks to lay down the principle of res judicata in so far as the application of that provision prevents the recovery of State aid granted in breach of European Union law which has been found to be incompatible with the common market in a decision of the Commission which has become final (see, to that effect, paragraph 63 of Lucchini). 57 In the present case, the court judgment possessed of the force of res judicata relied on by the Slovak Republic precedes the decision whereby the Commission requires the recovery of the aid at issue. 58 Consequently, as maintained by the Slovak Republic, Lucchini cannot be of direct relevance to this case. 59 Secondly, attention should be drawn to the importance, both in the European Union legal order and in the national legal orders, of the principle of res judicata. In order to ensure stability of the law and legal relations, as well as the sound administration of justice, it is important that judicial decisions which have become definitive after all rights of appeal have been exhausted or after expiry of the time-limits provided to exercise those rights can no longer be called into question (Case C-224/01 Köbler[2003] ECR I-10239 , paragraph 38;Case C-234/04 Kapferer[2006] ECR I-2585 , paragraph 20; andCase C-2/08 Fallimento Olimpiclub[2009] ECR I-7501 , paragraph 22). 60 Accordingly, European Union law does not in all circumstances require a national court to disapply domestic rules of procedure conferring the force of res judicata on a judgment, even if to do so would make it possible to remedy an infringement of European Union law by the judgment in question (see, to that effect, Kapferer, paragraph 21, and Fallimento Olimpiclub, paragraph 23).”
“A person seeking recognition or enforcement of such an award shall be entitled to have the award registered in the High Court subject to proof of the prescribed matters and to the other provisions of this Act.”
“The doctrine of sovereign immunity may prevent the forced execution in a State of judgments obtained against foreign States or against the State in which execution is sought. Article 54 requires Contracting States to equate an award rendered pursuant to the Convention with a final judgment of its own courts. It does not require them to go beyond that and to undertake forced execution of awards rendered pursuant to the Convention in cases in which final judgments could not be executed. In order to leave no doubt on this point Article 55 provides that nothing in Article 54 shall be construed as derogating from the law in force in any Contracting State relating to immunity of that State or of any foreign State from execution.”
“The Tribunal finds that it is not desirable to embark on predictions as to the possible conduct of various persons and authorities after the Award has been rendered, especially but not exclusively when it comes to enforcement matters. It is thus inappropriate for the Tribunal to base its decisions in this case on matters of EU law that may come to apply after the Award has been rendered. It will thus not address the Parties’ and the Commission’s arguments on enforceability of the Award.”
“The rights and obligations arising from agreements concluded before1 January 1958 or, for acceding States, before the date of their accession, between one or more Member States on the one hand, and one or more third countries on the other, shall not be affected by the provisions of the Treaties.”
