The aim of this paper is to analyse research undertaken on interest groups and their relationship with the European Court of Justice. Anchored in a politics of law perspective in the European Union, it argues that without taking into consideration how non-state actors, such as interest groups, NGOs or companies have used the Court would be an incomplete perspective to the Court’s role in the EU political system. On the contrary, the Court’s impact has been enhanced by the participation of private and public contributors, which have used the ECJ as a means to advance their own position and has created a virtuous circle reinforcing the integration process. The use of the Court by non-state actors, thus the juridicisation of lobbying strategies, is another illustration of the politics of law we see in the European Union.
