Translate the following English sentence to French:
"We therefore cannot find any Council document which refers to the exchange of notes between Belgium and the United Kingdom given that, under Community legislation, it is Member States which are responsible for deciding this by mutual agreement and given that this does not require approval by the Council."
Par conséquent, il est impossible qu' un document du Conseil mentionne l' échange de notes entre la Belgique et le Royaume-Uni, étant donné que, d' après la législation communautaire, les États membres sont seuls compétents pour décider de commun accord, sans un quelconque feu vert du Conseil.
