This open access book provides an exhaustive picture of the role that annulment conflicts play
in the EU multilevel system. Based on a rich dataset of annulment actions since the 1960s and a
number of in-depth case studies it explores the political dimension of annulment litigation
which has become an increasingly relevant judicial tool in the struggle over policy content and
decision-making competences. The book covers the motivations of actors to turn policy conflicts
into annulment actions the emergence of multilevel actors' litigant configurations the impact
of actors' constellations on success in court as well as the impact of annulment actions on
the multilevel policy conflicts they originate from.
