52According to the settled case-law of the Court, in order to ensure the primacy of EU law, the functioning of that system of cooperation requires the national court to be free to refer to the Court of Justice for a preliminary ruling any question that it considers necessary, at whatever stage of the proceedings it considers appropriate, even at the end of an interlocutory procedure for the review of constitutionality.
