66If, in the light of the information provided pursuant to Article 15(2) of the Framework Decision and any other information available to the executing judicial authority, that authority reaches the conclusion that, although it is based on the existence of an ‘arrest warrant’ for the purpose of Article 8(1)(c) of the Framework Decision, the European arrest warrant was in fact issued in the absence of any national arrest warrant separate from the European warrant, that authority must refuse to give effect to the European warrant on the basis that it does not satisfy the requirements as to lawfulness laid down in Article 8(1) of the Framework Decision.
