The articles in this volume provide evidence supporting the claim that organisational actors within the EU do engage in contestation over competences over a wide variety of legislative and policy-making procedures. Far from defining EU politics, treaty texts are only their beginning. The articles also provide evidence that informal changes may be translated into treaty change at a later date, although the evidence for this is more mixed. The various authors seek to take our initial arguments as a starting point to build on and point to important ways in which these arguments can be amended or extended. Nonetheless, it is clear that closer attention to processes of contestation and of interstitial change holds great promise as an approach to the understanding of EU politics.
