Cooperation with third countries on readmission has occupied an increasingly prominent place in the EU's migration management strategy. The EU and its Member States have progressively concluded an extensive set of bilateral and multilateral, binding and non-binding, cooperation instruments on readmission. This proliferation questions the field's coherence with the principle of sincere cooperation, governing the interplay between the Union's and Member States’ action. By taking this principle as a benchmark, the article highlights the ineffective nature of the current ‘unprincipled’ pursuit of readmission goals. It also demonstrates that sincere cooperation—if read together with subsidiarity—does not necessarily favour the Union's international action, to the detriment of the Member States’. Rather, it requires a good faith effort to identify, and stand by, the most effective level of action.

55 This is due to the fact that readmission is not framed by Article 79 TFEU as a parallel competence. Thus, its exercise by the Union is capable of pre-empting future Member States action.

As discussed above, according to the Court, action by all Member States outside the Treaty framework is, instead, possible whenever the Union itself would not be competent to undertake it, ie in areas that are still within the realm of national competence (Pringle v Ireland, C-370/12, EU:C:2012:756, para 105).

In fact, a duty to abstain from taking a certain action can be a consequence not only of the exclusivity of the Union's action, but also (directly) of the duty of cooperation.
