Historic reminder/explanation: this provision was included into the text of the Return Directive at a late stage of negotiations following a strong request from certain Member States which insisted that the Directive should not oblige them to change well-established practices of taking/passing back illegally staying third-country nationals to other Member States under bilateral agreements.
L'article 6, paragraphe 3 de la directive définit donc une exception qui concerne uniquement l'obligation de l'État membre sur le territoire duquel se trouve le ressortissant de pays tiers d'adopter une décision de retour, cette obligation incombant alors à l'État membre qui reprend ce ressortissant.
